Electronic Motor Speed Control 2. Electronic Motor Stop If the fan jams the motor will stop which save both the motor and the belt. 3. Mechanical nozzle lift prevents brushroll contact with the floor surface when the unit is in the accessory hose mode or locked upright and left running. 4. Electronic Suction Path Valve Control - When the hose is attached and the unit is upright and locked, the suction path is through the hose. When the unit is moved from the upright and locked position to the normal use position, the suction path automatically changes to through the power nozzle. If the hose isn t installed then the path stays through the nozzle no matter the position of the unit. 2

3 Electrical 1. The fuse on the logic board is for fire safety, not to protect the board. 2. If the motor current increases and the fuse doesn t blow, then the chip will shutdown the motor. 3. If left plugged in the unit will return to the speed in use when it was turned off. If unplugged then the speed will rev up to full speed. 4. On the power supply board the resistor marked will blow if the board goes bad. 5. If the LEDs are On but the unit doesn t function, turn Off, unplug, wait 30 seconds and plug it back in. Turn it On and the unit should work.

4 Tune-Up 1. Evaluate a. Cord assembly and harness condition i. Jacket free of holes especially at the entrance to the handle grip or nozzle housing ii. Plug blades secure and straight b. Cord dump function i. Holds in place while winding the cord c. Housing condition i. Tells a lot about how the unit was treated by the user ii. Fascia fixed in place d. Base/Sole plate assembly condition i. Normal wear ii. Edge brush condition iii. Microsweep condition iv. Rear wheel condition & function v. Front wheel condition & function e. Bumper condition f. Outer bag condition g. Inner bag dock condition & function h. Dirt tube condition i. Collar condition j. Handle condition k. Switch condition & function l. Motor condition & function m. Brushroll condition & function n. Belt condition & function o. Light cover condition & light function p. Yoke condition & function q. Pivot detent r. Accessory valve condition & function s. Height adjuster condition & function 2. Clean a. Check for clogging at the inlet of the pivot. b. Check the fan and fan housing for foreign objects. c. Clean the components: i. WD40 to remove marks from cords and bumpers ii. Oreck Glass & Mirror Cleaner iii. Oreck Hospital Clean (Liquid only, not the aerosol) iv. Steam cleaning is an effective method of cleaning. v. Use soap (Joy, Ivory, Dawn) and water as the primary cleaning ingredients. vi. Do not use Citrus-based cleaners (orange oil). They will cause most plastic to become brittle. 4

5 3. Replace a. Inner filter bag 4. Only when necessary - Low Power/Sparks - Commutator Polish a. It is not necessary to polish all commutators. Commutators in pictures 1 & 2 have a gray film. This is graphite from the brushes and desirable since it acts as a lubricant. Picture 3 shows heat and 4 uneven wear. These two should be polished b. Hazardous conditions will exist during this step: i. Wear safety glasses, remove jewelry from hands, wrists and neck (if dangling). Secure loose clothing and long hair. c. Another way to determine if polishing is necessary is to observe the arcing characteristics of the function while in operation. d. Maximum Acceptable Arc Continuous no greater than 1/16 i. e. Commutators producing more than the maximum acceptable arc should be polished. Brushes may have to be changed. f. Hazardous conditions will exist during this step: i. Exposure to spinning components: brushroll, motor, belt, fan and exhaust debris. ii. Wear safety glasses and remove jewelry from hands, wrists and neck (if dangling). Secure loose clothing and long hair. iii. Exposure to lethal amperage: Keep hands away from terminals, wires and motor components g. Lightly touch the commutator with the commutator cleaner. Burnishing will happen quickly. i. h. Turn the commutator cleaner over and do the same for the belt drive shaft. 5

6 i. Turn the unit off and unplug from outlet. 5. Wheels Grinding/Rattling/Worn - Rear Wheel Service a. Remove hubcap Insert flathead screwdriver blade into one of the 3 slots on the back of the wheel hub. Place the blade as shown in picture 1 and twist until hub tab has unhooked from the wheel hub picture 1 2, then push down. i. b. Remove wheel Remove E clip and washer Washer E clip i. c.

Disconnect the harness wires from the wire nuts and switch assembly 20

21 c. To remove a defective harness doesn t require the handle tube to be disassembled but, due to the grip switch connector, it will be difficult to fish the new harness back through the assembled tube. It will be much quicker and easier to extract all of the handle tube and harness screws (eight) at once, pull out the old harness and, when ready, thread the new harness through the yoke, tubes, connector and reassemble to grip. Lower and Upper Handle Tubes at the Connector Harness Over Mold Lower Handle Tube at the Yoke Yoke d. Disconnect the hot, neutral and switch leads from the control board.

23 e. To prevent snagging, install spring make sure the hook is as shown f. Position the spring so that the loop is visible inside the base Troubleshooting Valve Stuck in Hose Position Nozzle Side Blocked Hose Nozzle Defective Hall Effect Switch DCV measurement Defective Servo continuity should have continuity Defective Control Board elimination process 23

24 Valve Stuck in Nozzle Position Hose Side Blocked Hose Nozzle Hall Effect connector not plugged into control board - visual Hall Effect Switch installed upside down - visual Hose Sensing Switch no continuity with hose installed continuity should have continuity Defective Hall Effect Switch DCV measurement Defective Servo continuity should have continuity Defective Control Board elimination process 1. Hall Effect Switch Check DCV a. Conditions: Hose in place closes the hose-sensing switch (1), fan housing up and locked places the magnet (2) right across from the Hall Effect switch (3) unit turned ON. Hose Hose S. Switch Magnet 2. With the above conditions met a DCV measurement between the white lead of the control board to power supply and one of the hose switch terminals should be 0vdc (Picture 1). Remove the hose or lean the handle back and the measurement should be 5vdc (Picture 2). 24

25 1 The meter is showing 18.2 mvdc which is essentially 0 volts 2 Nothing Works Outlet - 120VAC Power Circuit - Continuity Power Cord to Harness Connection - Visual Harness - Continuity Power Switch Continuity If all the above are good and there is no 12VDC then the problem is in the: Power Supply - 12vdc If all the above are good then the problem is in the: Control Board 1. AC Outlet - 120VAC 2. Power Circuit Continuity Ω 25

26 a. Hot Touch a meter lead to the Hot/Narrow blade of the plug and the other meter lead to the Black lead connection on the Power Supply (1) - Continuity b. Neutral Touch a meter lead to the Neutral/Wide blade of the plug and the other meter lead to the White lead connection on the Power Supply (2) - Continuity 1 2 c. Continuity in both means the problem is not in the power cord or harness. Go to 5. d. No continuity in one or the other or both means the problem is in either the cord, grip connections or the harness (Go to 3) 3. Power Cord a. Remove the grip from the handle tube and open it b. If there are any loose wires reconnect them and perform the appropriate test (2a or b). c. If the wires are properly connected, then they are not the problem d. Remove the wire nut from the two Black leads and check the cord for continuity between the Hot/Narrow plug blade and the Black cord lead at the grip. e. Remove the wire nut from the two White leads& one and check the cord for continuity between the Neutral/Wide plug blade plug blade and the White cord lead at the grip. f. If d & e both have continuity then the cord is not the problem. Go to Harness a. Hot Touch a meter lead to the Black harness lead in the grip and the other meter lead to the Black lead connection on the Power Supply (1) b. Neutral Touch a meter lead to the White harness lead in the grip and the other meter lead to the White lead connection on the Power Supply (2) c. If a & b both have continuity then the harness is not the problem. Go to Power Switch Continuity Ω a. This check requires either two people or a lot of finger coordination. At least there are test points. 26

27 b. A multimeter lead will always be on the Blue Common test point. c. Place the other lead on the Brown On/Off test point, press and hold the Power switch should go from 0L to 0.00 or to 0 depending on the type meter. If the meter goes from 0L to some value then back to 0L you probably aren t getting a good push on the switch however this is enough to show the switch is working. d. Repeat the process at the Red test point for High and the Yellow test point for Low. Brown On/Off Red High Brown Yellow Red Blue Blue Common Yellow Low e. If all three switches have continuity then the switch is not the problem. Go to Power Supply 120VAC & 12VDC a. AC Volt Input b. With the Red meter probe in contact with the Black conductor of the connector and the Black probe in contact with the White conductor, plug in the power cord: 120VAC should be present as shown (119.7VAC) whether the unit is turned on or not. 27

28 c. With the Red meter probe in contact with the Red conductor of the connector and the Black probe in contact with the White conductor, plug in the power cord: 12VDC should be present as shown (11.89 VDC) whether the unit is turned on or not. d. No 12VDC Replace Power Supply. e. Both voltages present. Go to Control Board The control board is difficult to check by itself but by the process of elimination if all else works then it falls to the control board as the defective part. Everything Works But The Motor Motor connector not plugged into the control board - visual Motor rotor locked visual Motor burned out visual Motor Defective loose wires/worn brushes continuity should be continuity through the motor Control Board Defective VAC should be at the motor connection when the unit is turned on. 28

29 Everything Works But The LED Lights Defective Control Board 12VDC Defective LED Board 1. Control Board Output to the LED lights DCV a. Unplug the harness at the LED board. b. Tape the harness plug down as shown in Picture 1 1 Brown White Black 2. Plug in the power cord and turn the unit on (remember for DCV the black meter lead goes to Common and the Black lead goes to the voltage test point). a. In this case Brown is common so look for 12VDC between Brown and White then between Brown and Black b. If both are 12VDC then the LED board is defective c. If no 12VDC then the control board is defective 29
