MAINTENANCE
Spark plug
The condition of the spark
plug is affected by:
• An incorrect carburettor
setting.
• An incorrect fuel
mixture (too much or
faulty oil).
• A dirty air filter.
These factors cause
deposits on the spark plug
electrode that may result in
malfunction or starting
difficulties.
If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0.5 mm. The spark plug should be
changed after about one month of operation or earlier if
necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.
0,5 mm
Angle gear
The angle gear is filled with
a sufficient quantity of
grease at the factory.
However, before using the
machine you should check
that the angle gear is filled
to 3/4 with grease. Use
HUSQVARNA special
grease.
Normally, the grease does
not need to be changed
except when repairs are
carried out.
Two-part shaft
The end of the drive axle in
the lower shaft should be
lubricated with grease every
30 hours. There is a risk
that the drive axle ends
(splined coupling) on two-
part shafts jam if they are
not lubricated regularly.
