MAINTENANCE
Air fi lter
The air fi lter 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 fi lter every 25 hours, or more regularly if conditions
are exceptionally dusty.
Cleaning the air fi lter
Remove the air fi lter cover and take out the fi lter. Wash it
clean in warm, soapy water. Ensure that the fi lter is dry before
re fi tting it.
An air fi lter that has been in use for a long time cannot be
cleaned completely. The fi lter must therefore be replaced with
a new one at regular intervals. A damaged air fi lter must
always be replaced.
If the machine is used in dusty conditions the air fi lter should
be soaked in oil. See instructions under the heading Oiling the
air
fi lter.
Oiling the air fi lter
Always use HUSQVARNA fi lter oil, art. no. 531 00 92-48. The
fi lter oil contains a solvent to make it spread evenly through
the fi lter. You should therefore avoid skin contact.
Put the fi lter in a plastic bag and pour the fi lter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the
fi lter inside the plastic bag and pour off
the excess before fi tting the fi lter to the machine. Never use
common engine oil. This would drain through the fi lter quite
quickly and collect in the bottom.
An air fi lter that has been in use for a long time cannot be
cleaned completely. The fi lter must therefore be replaced with
a new one at regular intervals. A damaged air fi lter must
always be replaced.
Bevel gear
The bevel gear is fi lled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is
fi lled 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 in fl uenced by:
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (too much or incorrect type of
oil).
• A dirty air fi lter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
dif
fi culties.
If the machine is low on power, dif fi cult to start or runs poorly
at idle speed: always check the spark plug fi rst 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
fi tted with a suppressor.
