Oiling the air filter
Always use special filter oil. 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 on the gearbox. Use a grease
gun to top up with grease. This should be carried out after
approximately every 25 working hours. Use Husqvarna
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.

MAINTENANCE

Cutting unit

Check that the cutting units' screws are fitted correctly.

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.
