MAINTENANCE
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 40 hours, or more regularly if conditions
are exceptionally dusty.
Avoid contact with hot surfaces on muffler, cylinder etc.
Contact can result in burns to the skin.
Cleaning the air filter
Dismantle the outer cover with the help of the four fasteners
holding the outer cover.
Loosen the two fasteners holding the air filter cowling and
remove the filter. Wash the filter clean in warm, soapy water.
The air filter is fitted in the air filter cowling.
Ensure that the filter is soaked in oil 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.
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 60-76. 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.
