MAINTENANCE
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.
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.
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.

blades
CAUTION! Use only HUSQVARNA replacement parts. Use
of other brands of replacement parts can cause damage to
your unit or injury to the operator or others. Your warranty
does not cover damage or liability caused by the use of
accessories and/or attachments not specifically
recommended by HUSQVARNA.
!
WARNING! Always stop the engine before
doing any work on the cutting attachment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting attachment has stopped completely
and disconnect the HT lead from the spark
plug before you start to work on it.
