INTRODUCTION
The Chipper is intended for cutting peeled potatoes into chips or scallops, in a
batch process.
CHIPPER DIMENSIONS
All dimensions are in mm.

CHIPPER 3
INSTALLATION
For the Installer:
These Instructions contain important information designed to help the user
obtain the maximum benefit from the investment in an IMC Chipper.
Please read them carefully before starting work, and consult with the supplier in
the event of any queries.
Be sure to leave this Instruction Manual with the user after installation of the
machine is complete.
Procedure
The unit is designed to stand on a bench, 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.
The Chipper 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.
The IMC Chipper 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 7.
Position the Chipper 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. This socket or isolator must be accessible once the machine is
installed. Before connecting, check that the voltage shown on the rating is
correct for the electricity supply you have available. The outlet should be fused
at 13 amps.
NOTE: The plug is fitted with a 10amp fuse.
WARNING: This machine must be earthed
Should the supply cord become damaged then an approved electrician must fit
a replacement. The IEE Codes of Practice must be observed.
An equipotential bonding terminal is provided at the back of the unit near the
cable outlet for external earth bonding. Provision of an earth bond does not
remove the requirement for an earth in the electrical supply.

COMMISSIONING
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 IMC Chipper are the interlock
devices that 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 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 hopper
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. The rotor should be stationary within 2 seconds of the hopper being
opened. If the knife block is not in place, another interlock will prevent the
machine from running.
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 over size and which could otherwise clog the
mechanism. It is also essential that only potatoes be fed in to this machine.
NOTE: take great care to ensure that there are no stones mixed in with the
potatoes.
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. Should a stone damage the
knife blades they must be replaced as further use could break the blades.

CHIPPER 5
This Chipper is designed for batch process work; switch the machine off once
all the potatoes have been cut. The motor is fitted with a thermal trip that will
stop the machine if the motor overheats. This protection feature will
automatically reset itself when it cools down but it is necessary to wait a few
minutes for this to happen.
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.
CHANGE CHIP SIZES
To change to a different size of chip, change the knife block assembly. Spare
knife block assemblies are available from IMC. 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: 8mm, 11mm, 14mm and
14x17mm. Scallops can be cut with similar knife block assemblies. The
standard scallop size is 8mm.
CLEANING
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, open the hopper and lift it out of its hinge
seating at the back
3. Clean the hopper in a sink, dishwasher, pot wash or by hosing with a spray
4. Remove the knife block by lifting upwards, off its locating dowels
NOTE: Take care when handling the knife block. The blades are
sharp.
5. Clean the knife block under a spray or running tap and remove any
residual pieces of potato. DO NOT use any metallic objects, such as a
knife or screwdriver, to un-block the knife block. Visually inspect all blades
for wear or damage, and replace the knife pack as necessary. Do not
attempt to straighten a bent blade - bent blades should be replaced
immediately.
6. Lift the rotor carefully off its spindle.
7. Clean the rotor in a sink, pot wash, etc.
8. Clean out the interior of the base unit and wipe over the exterior with a
damp soft cloth. Do not hose down the exterior of the machine.
DO NOT USE CLEANING MATERIALS CONTAINING ABRASIVES OR
BLEACHES.
9. Reassemble the machine, reversing the above disassembly procedure.
When replacing the rotor, ensure that it is put back square on its spindle.
Make sure that it is properly seated on its cross pin by turning it slowly until
it drops onto this seating. When replacing the knife block it should slip
down easily on to its dowel pins, make certain that it is fully down.

CHANGING KNIFE BLADES
The knife blades are supplied as a pack and individual blades cannot be
changed. Change the knife blade pack as soon as it is damaged or blunt. To
change the knife blade pack remove the knife block and undo the two screws
securing the knife blade pack. Dispose of the old blades carefully and screw
the new knife blade pack in place. See diagram below.
For optimum performance IMC recommend changing the blade pack every 6
months, or sooner depending on usage.
NOTE: Take care when handling the knife block. The blades are sharp.
MAINTENANCE
Details of IMC Service Contracts are available on application.
ORDERING SPARE PARTS
In the event that spare parts or accessories need to be ordered, please always
quote the SERIES AND SERIAL NUMBER of the machine. This is to be found
on the rating plate located near the supply cable.
