MAINTENANCE
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 housing
There are three grease nipples on the gear housing. Use a
grease gun to top up with grease. This should be carried out
approximately every 20 working hours. Use Husqvarna
special grease, part 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 60-75 (UL22) before and after using
the machine.
Lubricate the blade bars with special grease, part no. 531 00
60-74 (UL 21) before long periods of storage
IMPORTANT! Use only HUSQVARNA replacement parts.
Use of other brands of replacement parts can cause
damage to your unit or injury to the operator or others. Your
warranty does not cover damage or liability caused by the
use of accessories and/or attachments not specifically
recommended by HUSQVARNA.
