MAINTENANCE
265RX
Remove the air lter cover and take out the lter. Wash it
clean in warm, soapy water.
Ensure that the lter is dry before retting it.
Oiling the air lter
Always use HUSQVARNA lter oil, art. no. 531 00 92-48. The
lter oil contains a solvent to make it spread evenly through
the lter. You should therefore avoid skin contact.
Put the lter in a plastic bag and pour the lter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the lter inside the plastic bag and pour off
the excess before tting the lter to the machine. Never use
common engine oil. This would drain through the lter quite
quickly and collect in the bottom.
An air lter that has been in use for a long time cannot be
cleaned completely. The lter must therefore be replaced with
a new one at regular intervals. A damaged air lter must
always be replaced.
Bevel gear
The bevel gear is lled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is 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 inuenced by:
Incorrect carburettor adjustment.
An incorrect fuel mixture (too much or incorrect type of
oil).
A dirty air lter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difculties.
If the machine is low on power, difcult to start or runs poorly
at idle speed: always check the spark plug rst before taking
any further action. If the spark plug is dirty, clean it and check
that the electrode gap is 0.5 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 tted with a suppressor.
