MAINTENANCE
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 HUSQVARNA special
grease.
The grease in the bevel gear does not nor-
mally need to be changed except if repairs
are carried out.
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.
WARNING: Always stop the en-
gine before doing any work on the
cutting attachment. This continues
to rotate even after the throttle has
been released. Ensure that the cut-
ting attachment has stopped com-
pletely and disconnect the HT lead
from the spark plug before you start
to work on it.
WARNING: Always discard a
blade that is bent, twisted, cracked,
broken or damaged 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.
Air filter
The air filter must be regularly cleaned to
remove dust and dirt in order to avoid:
S Carburetor malfunctions
S Starting problems
S Loss of engine power
S Unnecessary wear to engine parts
S Excessive fuel consumption
Clean the filter every 25 hours, or more
regularly if conditions are exceptionally
dusty.
Cleaning the air filter
Remove the air filter cover and take out the
filter. Wash it clean in warm, soapy water.
Rinse thoroughly. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long
time cannot be cleaned completely. The
filter must therefore be replaced with a new
one at regular intervals. A damaged air
filter must always be replaced.
