MAINTENANCE
Angle gear
The angle gear is filled with
a sufficient quantity of
grease at the factory.
However, before using the
machine you should check
that the angle gear is filled
to 3/4 with grease. Use
special grease.
Normally, the grease does
not need to be changed
except when repairs are
carried out.
NOTE: 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.

Air filter
The air filter should be
cleaned regularly removing
dust and dirt to avoid:
carburetor 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 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.
