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. Allow the filter to dry and then
oil it in according to the instructions.
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.
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.
MAINTENANCE

Gear

There is a plug for filling lubricant on the gear housing.
Use the grease tube to fill with grease and repeat every
25 hours. Use Husqvarna's special grease.
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.

Cutting unit

Check that the cutting units' screws are fitted correctly.
Tighten them with a tightening torque of 7-10 Nm.

Cleaning and lubrication

Clean any resin and plant residue from the blades using
cleaning agent 531 00 75-13 (UL22) before and after
using the machine.
Check that the blade edges are not damaged or
deformed. File away any burrs.
Check that the blades move freely. Remove the
lubrication plug in the gear housing and stick in the
combination spanner and turn back and forth.
Lubricate the blade bars with special grease, part no. 531
00 75-12 (UL 21) before long periods of storage.
