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.
Gear housing
There are three grease nipples on the gear housing. Use a 
grease gun to top up with grease. This should be carried out 
approximately every 20 working hours. Use Husqvarna 
special grease, part no. 503 98 96-01.
CAUTION! The gear housing must not be filled completely 
with grease. The grease expands as the machine heats up 
during operation. If the gear housing was completely filled 
with grease it could damage the seals and lead to leakage of 
grease.
The grease in the bevel gear does not normally need to be 
changed except if repairs are carried out.
Cleaning and lubrication
Clean any resin and plant residue from the blades using 
cleaning agent 531 00 60-75 (UL22) before and after using 
the machine. 
Lubricate the blade bars with special grease, part no. 531 00 
60-74 (UL 21) before long periods of storage
