4 CHIPPER
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.
