14 3 - Description Liquid system General information All the liquid circuit functions are operated via the MANIFOLD system and the pressure distributor. The use of pictorial symbols helps to clearly identify these functions. The MANIFOLD System From main tank From the rinse tank Depending on the model, there may be a 3-way valve to select the tank to suck from. It is black and is situated on the lower left-hand side of the blower. Optionally, a blue return valve can be fitted This allows a return flow circuit to be set up. This valve is located at the front of the mistblower, behind the operating unit. HLC Circuit The pressure circuit HLC (Hardi Liquid Circuit) is used with diaphragm pumps. The HLC distributor has three mechanical valves. Valve (A) operates the agitator. Valve (B) activates the powder mixer which flushes powder chemicals through the tank strainer. Valve (C) activates the rotating rinsing nozzle for rinsing the main tank inside when the liquid circuit is rinsed with clean water. Each function is identified by a pictorial symbol. Valves (A) and (B) are optional. Safety valves The safety valve protects the liquid circuit against over pressure in the event of failures or clogged lines. If the spring-loaded safety valve opens the liquid is lead back to tank via hose (A). The safety valve opens at15 bar. DANGER! Do not remove, bypass or block safety valve from the liquid circuit as this could put your safety at risk. 12

15 3 - Description Pressure pulsation damper The 321 pump is fitted with a pulsation damper on suction and pressure sides. The pressure side damper is pressureized. The dampers will reduce pulsations and secure an even flow from the pump. The pressuredamper should be inflatedto the pressure shown in the table on top of the pulsation damper (A).

16 3 - Description Operating units The fitted operating unit is the M70/2, BKC/2 or EVC/2. M70/2 Manual operating unit including a main on/off valve, a pressure adjustement valve, a pressure gauge and two section valves for RH and LH spray lines. Lever (A) is main on/off. Red knob (B) is pressure adjustment valve. Clockwise = increase. Anti-clockwise = decrease. BKC/2 Manual operating unit used in configurations with diaphragm pumps. The two section valves open or close the RH and LH spray lines ATTENTION! To start operation, one must increase the pressure turning the red handle (A). Turn clockwise to increase pressure or anti-clockwise to decrease it. Check the pressure gauge to see when it is at the correct pressure level. By closing the mechanical remote ON/OFF control, the flow is shut off to the nozzles and returned to the main tank. 14

17 3 - Description It is very important that the operating unit is correctly adjusted. Before using the equipment for the first time, it is necessary to adjust the pressure equalisation valve. A correctly adjusted pressure equalisation valve will allow the same flow rate as the nozzles at the section to bypass to tank when the section is closed. This avoids variations in pressure when one or two sections are shut off. The adjustment procedure is following: 1. Open the main on/off valve. 2. Put the pressure at, for example, 3 bar. 3. Close one of the sections (A) or (B). 4. With the valve of the closed section, adjust the pressure equalisation valve (C) until the pressure gauge3 bar again. 5. Open the section valve again and repeat the operation with the other section valve 6. Carry out a test by opening the two sections at the same time or one by one. If the operating unit is correctly adjusted the pressure should remain at 3 bar. ATTENTION! It is recommendable to carry out this adjustment as close to the intended working pressure as possible. ATTENTION! Carry out this adjustment ever so often as nozzle size is changed or as the nozzles flow rate increase as a result of normal wear. EVC/2 Electrically remote contolled operating unit. The main on/off valve, pressure adjustment valve and the two section valves are controlled by an electrical control box fitted to the tractor. The functions of the control box are described below: To direct spray liquid to the operating unit and spray lines select suction from main tank by the manifold valve. A. Main On/Off Switch B. Switch to open left-hand section. C. Switch to open right-hand section. D. Switch to increase or decrease pressure. ATTENTION! Inside the box is the electronic circuit board and fuses for each motor. Inside the box there are two spare fuses. It is very important that the operating unit is correctly adjusted. Before using the equipment for the first time, it is necessary to adjust the pressure equalisation valve. A correctly adjusted pressure equalisation valve will allow the same flow rate as the nozzles at the section to bypass to tank when the section is closed. This avoids variations in pressure when one or two sections are shut off. 15

18 3 - Description The regulation procedure is the following: 1. Open the two sections (B) and (C) on the electrical control box. 2. Put the pressure at, for example, 3 bar. 3. Close one of the sections. 4. With the pressure equalisation valve (E) of the closed section, adjust the pressure until the pressure gauge indicates 3 bar. 5. Open the section again and repeat the operation with the other section. 6. Carry out a test by opening the two sections at the same time or one by one. If the operating unit is correctly adjusted the pressure should remain at 3 bar ATTENTION! It is recommendable to carry out this adjustment as close to the intended working pressure as possible. ATTENTION! Carry out this adjustment ever so often as nozzle size is changed or as the nozzles flow rate increase as a result of normal wear. 16

19 3 - Description Air kit Axial fan Technical information The fans on HARDI ZENIT mistblowers have been designed with composite blades and their aerodynamic design offer a higher quantity and better distribution of air, less noise and less power consumption. A centrifugal clutch ensures a smooth start and stop. Flow levels go from 35,000 to 45,000 m3/h depending on the adjustments made to its components. AXIAL AIR KITS Model fan Fan Flow m3/h Gear Box AB mm speeds AB mm speeds ll those measurements have been made in wing position 3. (See Adjusting the fan) DANGER! NEVER exceed 540 rpmat the tractor PTO. Exceeding 540 rpm may cause severe damages to the fan and lead to severe personal injury or death! DANGER! Keep away from the air inlets and outlets while the fan is operating. Foreign objects may be expelled from the air outlet or a piece of cloth could be sucked into the air inlet. Risk of severe personal injury or death! The air kits are the most dangerous part of the machine. Do not repair, change or modify any of the parts but leave this to your HARDI dealer. Any repair jobs on air kits in requires qualified technicians. Adjusting the fan The angle of the fan blades can be adjusted to 4 positions. The factory setting is normally pos. 3. Decreasing the blade angle (minimum angle, position 1) reduces the flow and power consumption. Increasing the angle (maximum angle, position 4) increases the air flow and power consumption. This will adapt the mistblower different applications tractor sizes. To change the blade position you should do as follows: 1. Take off the suction grid. 2. Loosen the Allen screws (A) without taking them out completely. 3. Loosen the Allen screws (B) holding the nut at the back of the fan. 4. With both hands on opposite blades, turn them to the required position between 1 and 4. All the blades should turn at the same time. 5. Finally, check all the blades are in the same position (C)

22 3 - Description Protection grids All pneumatic fans have protection grids. These are fundamental to avoid accidents and stopping foreign objects from entering the fan. DANGER! Use of the air kit without protection grids is not permitted. DANGER! Do not remove the protection grids from the equipment whilst in use. DANGER! Do not go near the fan when the equipment is in use. Do not wear light or loose clothing. DANGER! Never put foreign bodies inside the fan via the grid, regardless whether it is in use or not. DANGER! Protect your hearing from fan noise by wearing EN 352-1:1992 homologated ear muffs or similar. DANGER! If you notice vibrations or abnormal noise, switch off the fan immediately. Air flow and pressure The following graphs show the air flow and pressure supplied by the two turbine models. These results have been calculated when the fan is in high gear. The capacities in low gear is less 15%. Pressure (mm H2O) Flow (m³/h) L - type Pressure Free These results have been calculated when the fan is in high gear. In the low gear the capacities are 45% less. Pressure (mm H2O) Flow (m³/h) L - type Pressure Free 20

23 3 - Description Gear Box The gear box for the P540 air kits has two speeds. The speed ratio is following: 1st speed = 1 / 6.6 Oil capacity: 1.75 litres. Oil type used is SAE 90. See Maintenance for how frequently the oil has to be changed. Pneumatic system The pneumatic system operates on low pressure and produces a high air speed in the spout to break up the spray film and create a very fine turbulent mist. Via the atomizers in the spout, the mist is distributed uniformly in the shape of a fan. Four types of spouts are available depending on boom type: A. Cannon with 1 outlet B. Spout with 2 outlets C. Spout with 3 outlets D. Spout with 4 outlets Ceramic discs are used to control the flow rate. This disc has two positions. If the disc is placed so the flow enters through its flat side, this will allow less to go through than if it enters through the cone-shaped side. Hydro-pneumatic System The hydro-pneumatic system operates on a medium to high pressure. This system takes advantage of the great amount of turbulence in the cone-shaped low-volume nozzle and distributes the spray liquid correctly. The air gets to the spout at high speed and this spreads the water in the shape of a fan. There are two types of spout, with three or five nozzles. These two spouts cannot be used together. E. Spout with 3 nozzles F. Spout with 5 nozzles 21

24 3 - Description IRIS system The IRIS application system allows for individual air adjustment as each outlet permits steep angling or even closing of the air supply, if necessary. The IRIS system provides the required droplet size and air conduction to the target. The most delicate and difficult part of the vine, the grape cluster, is safely treated throughout the season, due to a very easy and quick calibration with the IRIS system. A. Non-drip valve B. Nozzle C. Vane position indicator (angle) D. Air vane adjustment E. Air vanes 22

25 4 - Start up General information Important Information Before using the machinery, it is recommended that you read the instructions to obtain best results and avoid operational problems. Unloading the mistblower from the truck When loading or unloading the mistblower to/from a lorry by using a lever and pulley or a crane, use the suspension points shown on the diagram and make sure the straps used are strong enough. DANGER! Nobody must stand below or next to the machine during loading or unloading. Before starting up for the first time Although the surface of the metallic parts of the mist blower have been coated with a strong, protective product, we recommend you apply a layer of anti-corrosion oil (e.g. CASTROL RUSTILLO or SHELL ENSIS FLUID) to all metal parts to avoid chemical products discolouring the enamel, as well as to ease future cleaning. ATTENTION! This treatment should be repeated whenever the protective film wears off. Storage wheels On unhooking the equipment to exchange it for another or to store it away at the end of the season, a set of wheels could be installed below the chassis in order to be able to move it about easily. These wheels enable you to push the equipment and then you can fit it into any space in the warehouse that otherwise would be difficult to get to by tractor. Counterweights Check if it is necessary to place a counterweight on the front of the tractor, to increase the stability and steering performance. 23

26 4 - Start up Mechanical connections Coupling the driveshaft Initial installation of the driveshaft may involve having to cut the axle to adapt it to the tractor to which it will be hitched. To hitch it for the first time, proceed as follows: 1. Attach the mistblower to the tractor in such a way that the distance between the PTO shaft and the mistblower pump is the shortest possible. 2. Stop the engine and remove the ignition key. 3. If the driveshaft needs to be shortened, pull the two parts of the shaft apart. Fit the two parts of the shaft, one to the tractor and the other to the mistblower crankshaft and measure out the length that needs to be removed. Mark the protection guards. ATTENTION! The shafts must always have a minimum overlap of one third of their working length. 4. Cut both parts equally, using a saw. File the profiles afterwards to remove burrs. 5. Grease the profiles and reassemble male fitting and female fitting. 6. Fit the shaft to the tractor PTO and to the mistblower pump shaft. 7. Place the input part towards the tractor. Fit the chains to prevent the protection guards from rotating with the shaft. ATTENTION! To ensure long life of the driveshaft and prevent possible damage to the equipment, try to avoid working at angles of more than

27 4 - Start up Hooking up the mistblower If your mistblower has a semi-automatic quick hitch, follow the steps set out below: 1. Place the quick hitch boom in the hydraulic lift arms of the tractor. 2. Fit the linch pins to secure the boom to the hydraulic lift arms. 3. Completely lower the boom with the tractor s hydraulic lever. 4. Reverse the tractor until it touches the chassis, placing this as near the middle as possible. 5. Attach the top link to tractor and sprayerand adjust it by hand. 6. Raise the tractor s lower links with the hydraulic lever until the boom fits perfectly into place. 7. When the boom is correctly attached, the two hooks will close automatically and the equipment will be fixed to the tractor. 8. Put the safety pins of the semi-automatic quick hitch on to avoid the equipment from becoming detached during transportation or spraying. 9. Place the equipment at the height needed. 10. Ajdust the top link until the equipment is completely perpendicular to the ground. To detach the mistblower you should proceed in the following way: 1. Lower the tractor s hydraulic arms with the hydraulic lever until the equipment is touching the ground. 2. Pull the cable release the boom from the semi-automatic quick hitch. 3. Loosen the top link 4. Pull out the retaining pin from the top link to completely detach the mistblower. 5. Drive the tractor away slowly. ± WARNING! The tractor s hydraulic lower links should be moved very gently to prevent damages or tipping over. 25

28 4 - Start up Hydraulic connections Technical information If your equipment includes any type of function that requires a hydraulic system for it to work, you should take into account the type and number of connections will be needed. Necessary couplings The following list shows the models that need hydraulic outlets on the tractor in order to make any movement or connection. ZENIT B20 M Central lifting cylinder (A) (if it is fitted) = 1 double acting outlet ZENIT B20 HY Central lifting cylinder (A)= 1 double acting outlet Individual closing and opening boom cylinder (B)= 2 double acting outlets The quick couplings (C) are colour-coded to identify the various cylinders on the equipment. For boom B20 HY there is an optional electro-hydraulic control kit with which it is possible to control all the boom s movements by means of a joystick that is fitted to the hydraulic lever. With this system only one double acting outlet is necessary. CANNON L-M-T Hydraulic engine 180º turn = 1 double acting outlet Spout lifting cylinder = 1 double acting outlet Hydraulic control of the CANNON model The operating ranges of all three CANNON models are the same. The lifting cylinder is controlled via a double acting outlet on the tractor and can be set vertically between -10 to 80º compared to horizontal. The spout can be rotated180º by another double acting outlet. This allows treatment to either side independet of driving direction. 26

29 4 - Start up Electrical connections General information If your equipment includes an electrical component, please note the following information to correctly connect the equipment and to prevent problems when working. The voltage required by the electrical components is 12 V. Before connecting any component, make sure that the polarity is correct. Red wire = 12 V (+ positive) Black wire = (- negative) The connectors assembled on the electric components comply with the standards for the majority of modern tractors. If your tractor has another type of power supply connector, the supplied connector will need to be removed and adapted to the tractor connector. Installing the basic electrical control box Find a suitable location in the tractor cabin where the control box can be fitted and operated comfortably. It is recommended that you place it to the right of the driver s seat. ATTENTION! The control box must be properly attached to prevent vibrations and damages. The connector is an universal type with removable adaptor cap (A) and it should be able to be connected to any tractor. As an emergency solution, remove the connector and splice the wires directly to the battery. ± WARNING! Always remember: Red wire (+) Black wire (-) The basic control box is fitted with a spare fuse (B) available as replacement NOTE! Always replace the spare fuse again so a new fuse is available for future use. 27

30 4 - Start up Installing the control box type Spray Box If you have acquired the mistblower with HC2500, then it is equipped with the Spray Box. Find a suitable location in the tractor cabin where the control box can be fitted and operated comfortably. It is recommended that you place it to the right of the driver s seat. ATTENTION! The control box should be firmly attached to avoid vibrations or damages. The type of connector (A) is allmost universal and you should be able to plug it into any tractor. As an emergency solution you can dismantle the connector and connect the cables directly to the battery. ± WARNING! Always remember: Brown cable (+), blue cable (-). The basic control box is fitted with an thermal fuse. In the event of a failure the fuse heats up and cut the power. After cooling down, the fuse will reset. This may take between 2 and 10 minutes, depending on the temperature reached by the fuse. ATTENTION! The 25-pin connector (B) at the Spray Box is used for connecting to the HC2500 computer. NOTE! If the Spray box is not used, protect it against dirt and moisture by a cover. 28

31 4 - Start up Booms Technical Information booms can be adapted to several different spout combinations, depending on whether it is the pneumatic or hydropneumatic air system. B11 Fixed boom This type of boom is for treating one complete row. The spouts are totally adjustable as far as height and inclination is concerned. Loosen the screws on the spout supports and adapt the height and width. In order to direct the spout to the area to be treated it can be rotated. The three available spraying systems can be used with this. B20 Manual boom This type of boom is for treating four row sides or two complete rows. The spouts are totally adaptable to the type of crop. Loosen the screws on the spout supports and adapt the height and width. In order to direct the spout to the area to be treated it can be rotated. The left- and right-hand booms can be opened and closed manually. With the lifting cylinder (if it is fitted) it is possible to raise or lower the two booms at the same time. B20 Hydraulic boom This type of boom is for treating four row sides or two complete rows. The spouts are totally adaptable to the type of crop. Loosen the screws on the spout supports and adapt the height and width. In order to direct the spout to the area to be treated it can be rotated. The left- and right-hand booms can be opened and closed manually. With the lifting cylinder (if it is fitted) it is possible to completely raise or lower the two booms at the same time. 29

32 4 - Start up The B50 boom Available as a Y and Z version. Y is controlled by the hydraulic levers from the tractor and it requires 3 double acting outlets ( Two double acting outlets for folding and one double outlet for lift ). The B50 as Z version requires only a control box in the tractor cabin to operate all boom functions. 30

33 5 - Operation Liquid and Air Circuits Filling/washing location requirements When filling the sprayer with chemicals and water it is important to avoid spot contamination by spray chemicals in order to protect the subsoil water resources. A. If the mistblower is always filled at the same place, a special filling/washing location should be established. This should have a hard, liquid-impenetrable surface (e.g. concrete) securing against seepage and edges securing against run-off to the surrounding areas. The place should be drained to an adequate receptacle (e.g. slurry tank or similar). Any spillage or washings should be retained and diluted in order to be distributed on a larger area to ensure minimal environmental impact and avoid build-up of larger chemical concentrations at one spot. If no other requirements of distances exist, the following general recommendation of distance could be used. Not closer than: 1) 50 metres from public water supplies for drinking purposes, 2) 25 metres from non-public water supplies for drinking purposes, treatment sumps and cesspools of drainage systems, and 3) 50 metres from surface water (watercourses, lakes and coastal waters) and from nature reserves. B. Alternatively the sprayer can be filled in the field where the spraying is to take place. If so, choose a different location for each refilling. If no other requirements of distances exist, the filling should not be established closer than: 1) 300 metres from public or non-public water supplies for drinking purposes and 2) 50 metres from surface water (watercourses, lakes and coastal waters), treatment sumps, cesspools of drainage systems, and nature reserves. ATTENTION! Legislation and requirements vary from country to country. Always follow local legislation in force at any time. NOTE! It is the responsibility of the sprayer owner/operator to comply with all relevant legislation. HARDI cannot undertake any responsibilities for incorrect operation and use. Suction Filter This is located on the bottom left-hand side of the equipment and is easy to access. To clean the filter you should do as follows: 1. Close the three-way valve. 2. Shut the valve of the filter (A) before dismantling the filter. 3. Undo the filter housing (B) to access the filter screen. 4. Clean the filter (C) and assemble in reverse order. The filter should be cleaned after each spray job while remining spray liquid is still agitated. This will prevent operational problems caused by sediments. 31

34 5 - Operation Diaphragm pumps The maximum number of revolutions when in use is 540 rpm. It is selfpriming and can be run dry. Depending on the model acquired, the pump is fitted with 2 or 6 diaphragms. The operating system is the same for both, but the one with 6 diaphragms provides more flow. ATTENTION! Be careful to make sure the pump is perfectly greased when it is to be used. ATTENTION! See section Maintenance regaring lubrication intervals. Filling the main tank The tank is filled with water through the filling hole by removing the lid located on the top of the tank. The water used should be as clean as possible to obtain best results. Fill the tank using the filter to prevent impurities from entering the tank. For greater filling capacity, an overhead tank can be used. The tank should be filled to a third of its capacity with clean water before adding the chemical product. Always follow the instructions given on the product label!attention! Always fill through the tank strainer to prevent impurities from entering the tank. DANGER! Do not place the filling hose inside the tank. Keep it out of the tank at all times and only point it towards the filling hole. If the pressure hose were placed inside the tank and there was a drop in water supply pressure, the chemical product could be syphoned back and contaminate the water supply lines, plant and well. WARNING! If spray liquid is left in the tank, for safety reasons all valves must be shut. ATTENTION! The water supply line should be provided with a check valve as additional safety precaution. Follow local legislation in force at any time. ATTENTION! The water supply should be provided with a meter to avoid spillage by over-filling. Follow local legislation in force at any time. Draining the main tank To empty the tank via the drainage valve, turn the pin on the lower righthand side of the auxiliary tank. To close it again, turn the pin again and the valve will close automatically. ± WARNING! Do not forget to use protective clothing and gloves when doing this. 32

35 5 - Operation Pressure filters Pressure filters will catch any remaining impurities and prevent nozzles clogging. To avoid blockage of those filters it is very important to check them regularly and clean them after each spray job to avoid chemical residues to deposit and block ± WARNING! Wear appropriate personal protection when checking pressure filteres. As a minimum gloves and face shield. Agitation The dual-nozzle agitation system injects the chemical product at high pressure from the pump inside the tank creating a turbulence that mixes the product with the water to a uniform liquid. The standard agitation has 2 mm ventury nozzles. The ventury nozzle (B) allows an effecient agitation of the main tank content. Clean water tank The clean water tank is located at the top and integrated in the main tank design. It is used for washing hands, gloves and cleaning clogged nozzles, etc. Unscrew the cap (A) to fill the tank. Open the tap (B) for clean water. ± WARNING! Although this tank is completely separate from the main tank and should only be filled with clean water, the water is NOT suitable for drinking! 33

36 5 - Operation Powder mixer This is mixer will flush and dissolve powder chemicals through the tank strainer, eliminate lumpy spray liquid and improve mixing. ATTENTION! After use, the powder mixer should be switched off, as it uses a lot of flow. Gear Box When you are going to work with spray guns or just need agitaion in the main tank the fan can be disengaged at the gear box. The gear box is located behind the pump. When the gear lever (A) is in the middle position, the gear box is in neutral. If you cannot get it into gear, it is because the pinion and crows sprockets are not aligned. Engage the PTO again for a few seconds, then turn off again and try to put into gear again. ± WARNING! The PTO, pump and fan must stand completely still before the gear is changed. 34

37 5 - Operation Nozzles The standard nozzle can be closed individually by turning them 90º. When open the direction can be adjusted within a range of +/- 15º. A non-drip valve (A) is fitted to avoid chemical spillage the sections are shut off. The nozzle type (B) are a hollow cone nozzle, also known as ATR. They are colour-coded and the working range is 5-15 bar. This type of nozzle can also be used with hydro-pneumatic equipment. ATTENTION! It is not advisable to exceed 15 bar with ATR nozzles as the droplets would be too small, and the liquid will either evaporate under hot conditions or be lost due to wind drift. The pneumatic equipment is fitted with ceramic calibration discs. These discs have two possible positions,: Cone shaped side: higher output Flat side: lower output The function of these nozzles in the pneumatic equipment is to control the flow rate needed to break up the spray film. The working pressure ranges of the pneumatic equipment 0-4 bar. On CANNON models, there are three different spout types. Model L is only fitted on variants with one turbine. It comprises 4 bi-jet holders with two nozzles each. In addition to the spout nozzles there are three adjustable nozzles outside the spout which allows to treat the nearby crops also. Model T is itted on variants with two turbines. It has 7 bi-jet holders in a star-shaped pattern with three nozzles each. In addition to these nozzles, there are three adjustable nozzles outside the spout which allows to treat the nearby crops also. Model M is fitted on variants with two turbines. It comprises an outlet of 10 nozzles and there are two more with three nozzles each. You can adjust the direction in which the ends of the upper and lower spouts points 35

38 5 - Operation Booms Technical Information The ZENIT variants with pneumatic air kits can be fitted with two different boom types. To each of these booms several different combinations of air spouts can be adapted, depending on whether it is the pneumatic or hydro-pneumatic air system. B11 Fixed Boom This boom type is for treating one complete row. The spouts A are fully adjustable in height and inclination. The three spraying systems available can be adapted to this. The spouts can be fully adapted to the type of crop, either for treatment in specific areas or general treatment. B20 Manual and Hydraulic Boom This type of boom is for treating four row sides. The spouts are fully adjustable inheight and inclination. The three spraying systems available can be adapted to this. Bracket (A) adjust the distance to the row, depending on crop density. Bracket (B) adjusts the rear spouts backwards or forwards. Bracket (C) adjusts the spout distance to the rows depending on crop type and density. The spouts can be fully adapted to the crop type, either for treatment in specific areas or a general treatment. Bracket (D) adjusts the external spouts distance to rows depending on crop type and density. 36

39 5 - Operation Cleaning General information In order to be able to use your mistblower for many years, a maintenance programme needs to be followed. This programme should include a comprehensive cleaning procedure. ATTENTION! Always read the individual sections. Carefully read the maintenance task instructions before starting. If any part of these instructions is unclear, for safety reasons, please contact your HARDI dealer for further information. ATTENTION! A clean mistblower is a safe mistblower. A clean mistblower is always ready for action. Clean mistblowers are not damaged by pesticides and their solvents. Steps to follow: 1. Fully read the chemical product s label. Take note of any special instructions regarding protective clothing, deactivating agents, etc. Read the labels on the detergents and deactivating agents. If any cleaning procedure is specified, follow it accordingly. 2. Familiarise yourself with local legislation regarding the disposal of pesticides, mandatory decontamination methods, etc. Contact the appropriate department, e.g. Department of Agriculture. 3. Pesticide washings can usually be emptied out on a soakaway or retained at a washing location (See Filling/washing location requirements ). This must be an area not used for crop growing. You must avoid seepage or runoff of residue into watercourses, wells, springs, pools, etc. The fluid remaining after rinsing the equipment cannot be disposed of down a sewer. It must be emptied into a suitable soakaway. 4. Cleaning starts with calibration. A properly calibrated mistblower ensures a minimal amount of fluid remaining. 5. It is good practice to clean the mistblower immediately after use, leaving it safe and ready for the next spray job. This prolongs the life of the parts. 6. At times, the spray liquid may need to be left in the tank for a short time e.g. overnight or until weather is suitable for spraying. Unauthorised persons or animals should not have access the mistblower under these circumstances. 7. If the product applied is corrosive, all metal parts of the machine before and after use should be coated with a suitable rust inhibitor. Cleaning and maintaining the filters Clean filters ensure: Mistblower parts, such as the valves, diaphragms and operating units, are not blocked or damaged during use. Nozzles are not blocked during spraying. The pump has a long service life. A clogged suction filter will result in pump cavitation. The main filter that protects the mistblower parts is the suction filter. Check it regularly. Cleaning the tank and liquid system 1. Dilute remaining spray liquid in the tank with at least 10 parts of water and spray the liquid out in the crop/orchard just sprayed. 2. Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivating agents if necessary. 3. Rinse and clean mistblower and tractor externally. Use detergent if necessary. 4. Remove tank and suction filters and clean. Be careful not to damage the mesh. Replace suction filter top. Replace filters when the sprayer is completely clean. 37

40 5 - Operation 5. With the pump running, rinse the inside of the tank. Don t forget the tank roof. Rinse and operate all components and any equipment that have been in contact with the chemical. Before opening the distribution valves and spraying the liquid out, decide whether this should be done in the field again or on the soakaway. 6. After spraying the liquid out, stop the pump and fill at least 1/5 of the tank with clean water. Note that some chemicals require the tank to be completely filled. Add appropriate detergent and/or deactivating agent, e.g. washing soda or Triple ammonia. 7. Start the pump and operate all controls enabling the liquid to come into contact with all the components. Leave the distribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short period. Check the label. 8. Drain the tank and let the pump run dry. Rinse inside of the tank, again letting the pump run dry. 9. Stop the pump. If the pesticides used have a tendency to block nozzles and filters, remove and clean them immediately. 10. Replace all the filters and nozzles and store the mistblower. If, from previous experiences, it is noted that the solvents in the pesticide are particularly aggressive, store the sprayer with the tank lid open. ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the pressure to 1.5 bar (20 psi) when spraying diluted remaining liquid in the field just sprayed. ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely. ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended. Use of rinsing tank and rinsing nozzles (optional) The incorporated rinsing tank can be used for two different purposes. ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely. In-field diluting before cleaning In-field diluting of remaining spray liquid residue in the spraying circuit, before cleaning the sprayer. Rinsing the tank and liquid system: 1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of all nozzles. 2. Turn suction valve towards Rinsing tank and pressure valve towards Spraying. 3. Engage and set the pump at approximately 300 r.p.m. 4. When 1/3 of the contents in the rinsing tank is used, turn suction valve towards Main tank and operate all valves on the pressure side of the system in the following order so that all hoses and components are rinsed: Turn the suction valve towards Main tank and the pressure valve towards Spraying and spray the liquid in the field just sprayed. Cleaning of Main tank: 5. Turn the suction valve towards Rinsing tank and the pressure valve towards Internal Tank Rinsing. Remove the filling strainer to avoid any cleaning shadows behind it. 6. When another 1/6 of the contents in the rinsing tank is used, turn the suction valve towards suction from Main tank. 7. Turn pressure valve towards Spraying and spray the liquid in the crop/orchard just sprayed. 8. Repeat point 6-8 one more time. ± WARNING! When critical chemicals have been used, before spraying another crop/orchard sensitive to the chemical just used or a cleaning detergent is recommended, do an extra cleaning: 9. Fill the rinse tank again. 38

41 10. Fill some clean water in the main tank. 11. Add the cleaning detergent to the main tank. Follow instructions on the label of the cleaning agent. 12. Clean the whole system again. 13. To get the best cleaning effect the suction and pressure filteres should be washed with clean water. 14. Rinse the sprayer with clean water afterwards. 5 - Operation ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually with a brush afterwards, especially if crops sensitive to the chemical just sprayed are to be sprayed afterwards! Rinsing when main tank is not empty Rinsing the pump, operating unit, spray lines, etc. in case of stop in spraying before main tank is empty (e.g. beginning rain etc.). Cleaning of the liquid system: 1. Turn suction valve towards Rinsing tank. (Keep pressure valve in Spraying -position). 2. Close AgitationValve (no agitation). 3. Engage the pump and spray the water from the rinsing tank in the field until all nozzle tubes/nozzles have been flushed with clean water. 4. Disengage pump again. ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the pressure to 1.5 bar (20 psi) when spraying diluted remaining liquid in the field just sprayed. ATTENTION! If the sprayer is cleaned with a high pressure cleaner, lubrication of the entire machine is recommended. 39

42 5 - Operation Operating rinse tank and nozzles The size of the rinsing tank depends of the main tank size: Tank Capacities, litres Main Tank Rinsing Tank Rinsing tank is located at lower left-hand side of the chassis and is totally independent from the main tank. The lid (A ) is located on the left-hand side of the equipment. The lid is secured with a string. The rinsing tank should always be filled by clean water through a hose separated from the mistblowers liquid circuit to avoid contamination. To clean the tank select Rinsing tank on the three-way valve located above the suction filter. The multi-hole rinsing nozzle is located inside the main tank. When pressurized the multi hole nozzle will rotate fast and rinse down spray chemical residues from the tank walls. To activate this multi-hole rinsing nozzle for internal cleaning you should turn the tap located on the pressure distributor. Unexpected interruptions If you have to stop a treatment unexpectedly, due to bad weather for example, and there is still some liquid in the tank, we recommend you rinse the tank, operating unit and pipes. Close the nozzles and switch off the PTO. Close the suction filter valve and open the filter. Immediately put clean water down the suction hose which goes straight to the pump and open up the nozzles. Follow the procedure until clean water comes out of the nozzles. Stop the pump and put the suction filter back in place. 40

43 6 - Maintenance Lubrication Transmission shaft The universal joints and needle bearings should be lubricated with grease. At the points shown,you should do (A) every 8 working hours and the profile tubes (B) every 20 working hours. Diaphragm pump Grease the pump after every 50 working hours or once a month, through the grease nipple located at the crankshaft end. The grease is distributed through the crankshaft to ball bearings, connecting rods, etc. On both the 321 and the 363 pump models, greasing is done in the same way. ± WARNING! A lack of grease in the pump could cause it to overheat and destroy moving parts. Filters and fittings Clean and inpect the filters for damages every 50 working hours. ATTENTION! Insufficiently maintained filters leads to numerous unwanted stops during a working day. ATTENTION! Lubricate the seal lightly with oil or grease every time the filter is dismantled to ensure the seal will slide correctly in place and seal. ATTENTION! A broken or leaking O-ring or sealing in the suction circuit leads to suction of false air and huge vibrations and pressure pulsations. 41

44 6 - Maintenance Diaphragm pump Replacement of valves and diaphragms. The procedure is similar for both models 321 and 363 pump. 321 pump 1. Dismantle the valve cover. 2. Replace the valves and O-rings. 3. Undo the bolt and replace the diaphragms. 4. At this stage make sure that the diaphragms are fitted in the correct position. The part indicated must be facing outwards. 5. Tight the screw which is supporting the diaphragm at the maximum with 6 Nm. 6. Lubricate seals and fit the valves. Take care not to fit valves on upside-down. 7. Fit the diaphragm cover again. When the cover is placed on top of the diaphragm, and before the bolts are tigtened, turn the crankshaft one turn to seat the diaphragm correctly in the cover 363 pump 1. Dismantle the valve cover. 2. Replace the valves and O-rings. 3. Undo the bolt and replace the diaphragms. 4. Remember to place the diaphragms with part number up-wards. 5. Reassemble the pump placing the valves in the correct position. When the cover is placed on top of the diaphragm, and before the bolts are tigtened, turn the crankshaft one turn to seat the diaphragm correctly in the cover. Take care not to fit valves on upside-down. 6. Fit the diaphragm cover again. When the cover is placed on top of the diaphragm, and before the bolts are tigtened, turn the crankshaft one turn to seat the diaphragm correctly in the cover ATTENTION! Note that there are two different types of valves on the upper diaphragm covers. Note orientation when dismantling. Mechanical clutch The clutch will transfer power via the pump to the gearbox. It consist of two sprockets (A) and a double chain (B) which holds them together. The chain must be greased every 50 hours to avoid unnecessary wear and tear. When the chain is worn, it is recommended to change all parts, as a new chain on worn sprockets will wear faster. 42

45 6 - Maintenance Regular checks After every 10 hours of use 1. Clean the suction filter 2. Clean the pressure filters 3. Clean/inspect the nozzles 4. Check for leaks in the liquid circuit 5. Check for leaks on the suction circuit After every 50 hours of use 1. Carry out the checks mentioned above 2. Check the pressure in the pressure pulsation damper (if it is fitted) 3.

Service check of the pump 5. Service check of the gear box 6. Check the pressure gauge 7. Service check of the air kit 43

46 6 - Maintenance Off season storage Winter storage At the end of the season, some extra time should be dedicated to the equipment before storing it during the winter time. It is recommended you store it in a place where it cannot be affected by freezing temperatures. Put at least 10 litres of antifreeze covering 33% of the inside of the tank and turn the pump for a few minutes so that the entire circuit is filled by the solution. As anti-freeze is an oily solution it also avoids the hoses and all the non-metallic parts from drying up during the period of time that the equipment will be out of use. Preparing the equipment for use after storage After storage, the equipment should be prepared well, thus guaranteeing it is in good condition for the new season. To do this correctly, follow the steps set out below: 1. Take off the protective canvas cover if you had put one on. 2. Fit the pressure gauge again. Change the old Teflon. 3. Connect the equipment up to the tractor, including the electric cables and hydraulic hoses. 4. Check the hydraulic functions. 5. Drain the remaining anti-freeze from the tank. 6. Completely rinse out the liquid circuit with clean water. 7. Fill the tank with clean water and check all its functions. 44

47 7 - Fault finding Operational problems General information In almost all breakdowns, the same factors always seem to be present: 1. Small pores or air leaks in suction side reduce the pump s capacity or stop suction completely. 2. A blocked suction filter causes the pump not to suction properly. 3. Clogged pressure filters cause pressure to rise in the pressure gauge but to fall in the nozzles. 4. Foreign bodies in the valves can cause the valve to not close completely. This reduces the pump s performance. 5. Poorly re-assembled pumps, especially diaphragm covers, causes the pump to suck air and reduces the pump suction. 6. Hydraulic components that are contaminated with dirt result in rapid wear or malfunctioning to the hydraulic system. Therefore ALWAYS check that: 1. Suction, pressure and nozzle filters are clean. 2. Hoses have no splits or cracks, especially the suction hoses. 3. Gaskets and o-rings are in good condition. 4. Pressure gauge marks the correct indication. Correct dosage depends on its accuracy. 5. Operating unit is in good working order. Use clean water to check it. 6. Hydraulic components are maintained clean. 45
