Cleaning the tool

Dismounting the cutter blades
CAUTION:
Always wear gloves when dis-
mounting the cutter blades.
When cleaning, sharpening, or replacing the cutter
blades, dismount them by the following procedure:
1. Remove the blade cover.
2. Set the box wrench onto the nut. Rotate the box
wrench so that the hole in the lower blade aligns with
the hole in the upper blade.

Look into the hole in the lower blade to check if the
correct hole in the upper blade is aligned. In the upper
blade, there are pins and two types of holes; true circle
and oval. Align the true circle hole in the upper blade
with the hole in the lower blade and then insert the hex
wrench into the holes.

the lower blade, you can insert the hex wrench
