Maintenance and Cleaning

Replacing the Bottom Cutter (see figure B)
Unscrew the adjustment screw 11 of the bottom
cutter. Fully unscrew the fastening screw 12 of the
bottom cutter and remove the bottom cutter 9.
Insert a new bottom cutter 9 into the recess of
the cutting base 10. Fasten the bottom cutter
with the fastening screw 12.
Check the cutter clearance a (see "Adjusting
Cutter Clearance a", page 7).
For adjustment of cutter
clearance b, the stroke mech-
anism of the upper cutter
must be at the upper dead
center point. For this, briefly
switch the power tool on and
then immediately off again.
Repeat the procedure again,
as required.
Before any work on the power tool itself,
pull the mains plug.
For safe and proper working, always keep the
power tool and the ventilation slots clean.
