MAINTENANCE
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Air filter
The air filter must be regularly cleaned to remove dust and dirt
in order to avoid:
• Carburettor malfunctions
• Starting problems
• Loss of engine power
• Unnecessary wear to engine parts.
• 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. 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.
If the machine is used in dusty conditions the air filter should
be soaked in oil. See instructions under the heading Oiling the
air filter.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The
filter oil contains a solvent to make it spread evenly through
the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.
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.
Drive shaft
The flexible drive shaft is lubricated with special grease. The
shaft must be lubricated at least every 25 working hours. A
tube of drive shaft grease is supplied with every machine.
NOTE! Do not use gearbox grease on the drive shaft.
• Lift up the locking button that holds the drive shaft sleeve
in the clutch cover.
• Remove the clip that holds the throttle wire against the
drive shaft.
• Pull the drive shaft sleeve out of the clutch cover.
• Remove the drive shaft from the sleeve either by shaking
it out or pulling it out using pliers.
