3 2 CHIPPER PC1 INTRODUCTION The Chipper PC1 is intended for cutting peeled potatoes into chips or scallops. GUARANTEE This machine is guaranteed by IMC for twelve months from the date of its purchase from IMC, or from one of its stockists, dealers or distributors. The guarantee is limited to the replacement of faulty parts or products and excludes any consequential loss or expense incurred by the purchasers. Defects which arise from the faulty installation, inadequate maintenance, incorrect use, connection to the wrong electricity supply or fair wear and tear are not covered by the guarantee. The guarantee applies in this form to installations within the United Kingdom only. Please observe these instructions carefully. ON DELIVERY The machine is packaged in a non-returnable transport carton. Please check the contents against the following list and notify both the carrier and the supplier within 3 days if anything is missing or damaged. Assembly Quantity Main body and connection cable 1 Hopper 1 Rotor (assembled to unit) 1 Knife Block (in separate box) 1 WARNING - TAKE CARE WHEN HANDLING THE KNIFE BLOCK; THE BLADES ARE SHARP Accessories may be one or more of the following, as ordered:- 1 Mobile Stand 2 Spare knife block 3 Scallop block SELECTION OF SITE The unit is designed to stand on a bench or table, or on a draining board. Ensure that whatever is used for this purpose is sturdy and rigid and not more than 750 mm high. A higher table makes it difficult to load the machine. A stainless steel mobile stand, which enables the unit to be moved about, is available as an option. The Chipper PC1 should be placed where supplies of peeled potatoes from the peeling machine are readily accessible, after which the output of chips need to be in easy reach of the fryer.

4 CHIPPER PC1 3 The IMC Chipper PC1 has a top loading hopper into which potatoes can be tipped from either side or from the front. It is not handed, and no consideration need be given to its loading direction. The discharge of chips is from the chute at the front of the machine, and the machine should be placed so that this chute is directly over the receiving container. ELECTRICITY SUPPLY CONNECTION A Wiring Diagram is shown on Page 6. Position the Chipper PC1 in the chosen site. The electricity supply connection should be made to a power outlet socket or isolator mounted on the wall close to the machine. Before connecting, check that the voltage shown on the rating plate at the back of the machine is correct for the electricity supply you have available. The outlet should be fused at 13 amps. NOTE: the unit is fitted with a 10amp fuse. WARNING - THIS MACHINE MUST BE EARTHED TESTING Open the hopper by fully unscrewing the interlock knob at the front and lifting up until the hopper is fully resting back on its hinges. Turn the rotor by hand to ensure that it is completely free to rotate and that the knife block assembly is properly in position. Replace the hopper and screw down the interlock knob until it is tight. It is now safe to switch on at the wall socket and to start the machine by pressing the start button on the front of the machine (green button). To stop the machine press the red button. One of the safety features provided on the Chipper PC1 is the interlock device which ensures that the machine cannot run unless both the knife block and the hopper are properly and fully in position. This makes it impossible for the operator to touch the spinning rotor because it is fully covered whilst it is running. To confirm that the interlock is operating correctly press the start button to switch the machine on. Then whilst it is still running, unscrew the interlock knob. After two or three turns the machine should switch off, but there are still two or three further turns of the knob necessary before the hopper can be opened. By the time it is possible to hinge the hopper open, the rotor inside should be stationary. If the knife block is not in place, a magnetic switch will prevent the completion of the electrical control circuit, and the machine will not run. OPERATION With the machine running, feed peeled potatoes into the hopper. It will hold approximately 12kg of potatoes which self feed into the mechanism of the machine and discharge as cut chips from the chute. Some care is necessary when loading as the rotor will not accept abnormally large potatoes, so these must be cut into two. The hopper is specially designed not to pass potatoes which are overlarge and which could otherwise clog the mechanism. It is also essential that only potatoes are fed in. NOTE: take great care to ensure that there are no stones mixed in with the potatoes.

5 4 CHIPPER PC1 A stone or any other foreign object will damage the cutting knives and could cause the machine to jam. In this event the machine has an inbuilt protection device which will switch it off before the electric motor burns out. This overload protection feature will automatically reset itself when it cools down but it is necessary to wait a few minutes for this to happen. After clearing the jam resume operation by pressing the start button. The machine will switch itself off in the event of failure of the electricity supply whilst operating. When the supply is restored the machine must again be switched on. It is fitted with no-volt release. In normal use the machine is stopped by pressing the red button next to the start button. TO CHANGE CHIP SIZES To change to a different size of chip, change the knife block assembly. Open the hopper, lift out the knife block and replace with the alternative selected. Knife blocks are available in the following sizes from the standard range: 6 mm, 9 mm, 10 mm, 12 mm, 14 mm. Scallops can be cut with similar knife block assemblies. The standard scallop size is 6mm but 4mm can also be supplied. Other sizes for both chips and scallops can be provided to special orders. MAINTENANCE Daily It is essential to clean the machine at least once a day, preferably at the end of each period of operation. 1 Switch off at the socket or isolator 2 Fully unscrew the interlock knob 3 Open the hopper and lift it out of its hinge seatings at the back 4 Clean the hopper in a sink, dishwasher, potwash or by hosing with a spray 5 Remove the knife block by a straight lift off its locating dowels NOTE: Take care when handling the knife block. The blades are sharp. 6 Clean the knife block under a spray or running tap and remove any residual pieces of potato. 7 Lift the rotor carefully off its spindle 8 Clean the rotor in a sink, potwash, etc. 9 Clean out the interior of the base unit and wipe over the exterior. A proprietary cleaner may be used but do not use neat bleach on the stainless steel 10 Reassemble the machine, reversing the above disassembly procedure

6 CHIPPER PC1 5 When replacing the rotor, ensure that it is put back square on its spindle. Do not force it or the centre bush could be damaged. Make sure that it is properly seated on its crosspin by turning it slowly until it drops onto this seating. When replacing the knife block it should slip back easily on to its dowel pins, but make certain that it is fully down. At infrequent intervals it is advisable to check tooth belt tension. Details of IMC Service Contracts are available on application. REPLACEMENT OF BLADES NOTE: Take extra care when carrying out these operations because of the sharp blades. 1 To replace blunted blades The most convenient way to replace blunted blades is to exchange the whole set including the mounting block. After removing the knife block assembly from the machine invert it. Remove the slicer blade and unscrew the two large slotted nuts. Separate the blade assembly from the carrier plate by pulling apart. Re-assemble with the new knife block making sure the grey bottom plate is fitted into its original position 2 To replace an individual cutter blade (slit blocks only) Dismantle knife block assembly as instructed above. Remove one nut from the blade assembly. Withdraw stud and pin to release defective blade. Replace with new blade and re-assemble in reverse order. 3 To replace the slicing blade The slicing blade is fixed to the knife block by two small screws. Unscrew these and withdraw the blade. Refit the new slicing blade in the same way. 4 Sharpening blunted blades (slit blocks only) It is quite feasible to dismantle the knife block as described and then to sharpen the blades on an oilstone, taking care to maintain the original angles. The tips of the cutting blades must be slightly proud of the edge of the slicing blade when re-assembled. If this cannot be achieved because of previous sharpenings then the blades must be renewed. ORDERING SPARE PARTS When ordering from the Parts List on the following pages, it is important to quote the Series Number and Voltage of the machine which are shown on the Rating Label on the back of the machine.
