Figure 12
– Knife Changing Equipment
The knife changing equipment shown in Figure 12
is included in the cutter tool kit. The following
instructions show how to remove and install a new or re-sharpened knife. Read through these
instructions AT LEAST ONCE before attempting to begin changing or installing any blades.
7.1 Knife Removal
1. Make sure the knife and clamp are in the up position. Switch the main power to the OFF position
and disconnect the machine power cord to prevent accidental power-up while servicing the cutter.
2. Unscrew the knife adjusting screws on top of the knife bar several turns (Figure 13). A new knife
will cut deeper than one that has been ground several times. Failure to back off the screws could
damage the knife and/or the cutting stick.
