authorized service center to replace them if
necessary.
Cleaning the tool
Clean the attachment by wiping off dust, dirt, or cut off
grass with a dry cloth or one dipped in soapy water and
wrung out. Remove the cut off grass or debris adhered
to the cutter blade.
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.

wise, the true circle hole comes after the pin.
• When the oval hole is aligned with the hole in
the lower blade, you can insert the hex wrench
but there is a lot of backlash.

lower blade, you can see the screw thread in
the pin. In this case, you cannot insert the hex
wrench fully.
