Sharpening grass cutters and
grass blades
S See the cutting attachment packaging for
correct sharpening instructions.
S Sharpen blades and cutters using a
single--cut flat file.
S Sharpen all edges equally to maintain the
balance of the blade.
W ARNING: Always discard a
blade that is bent, twisted, cracked,
broken or dama ged in any other
way . Never attempt to straighten a
twisted blade so that it can be re-
used. Only use original blades of the
specified type.
W ARNING: Always stop the en-
gine before doing any work on the
cutting attac hment. This continues
to rotate eve n after the throttle has
been released. Ensure that the cut-
ting attachment has stopped com-
pletely and disconnect the HT lea d
from the spark plug before you start
to work on it.
Bevel gear
The bevel gear is filled with the right quan-
tity of grease at the factory. However, be-
fore using the machine you should check
that the bevel gear is filled three--quarters
full with grease. Use JONSERED special
grease.
The grease in the bevel gear does not nor-
mally need to be changed except if repairs
are carried out.
