Air filter

The air filter (A) should be
cleaned regularly removing
dust and dirt to avoid:
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel
consumption
Clean the filter after every 25
hours or more regularly if
operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover (B) and remove the air filter.
Wash in clean, warm soapy water. Ensure that the filter is dry
before refitting.
An air filter used for a long period of time can never be cleaned
completely. Therefore it is necessary to replace the filter from
time to time with a new filter. 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 the section on "Oiling the air
filter".
Oiling the air filter
Always use HUSQVARNA
filter oil, order 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 the 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 on the
machine. Never use common
engine oil. This would drain
through the filter quite
quickly and collect in the
bottom.

MAINTENANCE

Gearbox

There are three grease nipples
on the gearbox. Use a grease
gun to top up with grease.
This should be carried out
after approximately every 20
working hours. Use
Husqvarna special grease,
No. 503 98 96-01.
Note that the gearbox must
not be filled completely with
grease. The grease expands
as the machine heats up
during operation. If the
gearbox was completely
filled with grease it could
damage the seals and lead to
leakage.
The lubricant in the gearbox does not normally need to be
replaced other than with repair.
Cleaning and

lubrication

machine clean any resin and
plant residue from the blades
using cleaning agent 531 00
60-75 (UL22).
Always lubricate the blade
runners with special grease
531 00 60-74 (UL 21) before
use.
