MAINTENANCE
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 503 47 73-01. 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.
Bevel gear
The bevel gear is filled with the right quantity of grease at the
factory. However, before using the machine you should check
that the bevel gear is filled three-quarters full with grease. Use
HUSQVARNA special grease.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
