Cleaning The Air Filter - Husqvarna 325HS75 Operator's Manual

MAINTENANCE
Air filter
The air filter (A) should be
cleaned regularly removing
dust and dirt to avoid:
• carburetor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel consump-
tion
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
filteF.
Oiling the air filter
Always use
HUSQVARNA
filter oil, order no. 503 47
73-01. Tile 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 com-
mon engine oil. This would
drain through the filter
quite quickly and collect in
the bottom.
Gearbox
There is a grease nipple (A)
on the gearbox. Use a grease
gun to top up with grease.
This should be carried out
after approximately every 20
working hom_. 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.
Lubrication
Always lubricate the blade
runners with special grease
