MAINTENANCE
• Coat the shaft with grease from the tube. Spread it with a
brush or rag.
• Slide the drive shaft back into the sleeve. Make sure the
shaft engages correctly by turning it and pushing at the
same time.
• When the shaft is correctly installed in the sleeve, the end
of the shaft should project about 10 mm beyond the edge
of the sleeve.
• Rotate the shaft and push it in at the same time.
• Install the drive shaft sleeve in the clutch cover so that the
hole is positioned directly underneath the locking button
on the clutch cover.
Bevel gear
The bevel gear is filled with the right quantity of grease at the
factory. However, before 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 normally need to be
changed except if repairs are carried out.
Spark plug
The spark plug condition is influenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type of
oil).
• A dirty air filter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difficulties.
If the machine is low on power, difficult to start or runs poorly
at idle speed: always check the spark plug first before taking
any further action. If the spark plug is dirty, clean it and check
that the electrode gap is 0,6-0,7 mm. The spark plug should
be replaced after about a month in operation or earlier if
necessary.
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.
Check that the spark plug is fitted with a suppressor.
