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
There is a grease nipple and a plug for filling lubricant on 
the gear housing. Use a grease gun to fill with grease. 
This should be done after every 60 working hours. Use 
Husqvarna’s special grease, 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.
