MAINTENANCE
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 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.
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.
Lubricate the blade bars with special grease, part no. 531 00
75-12 (UL 21) before long periods of storage.
