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.
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 Metcalfe 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.
