Fuel Filter; Air Filter - Husqvarna 375K Operator's Manual

Fuel filter

• The fuel filter sits inside the fuel tank.
• The fuel tank must be protected from contamination when
filling. This reduces the risk of operating disturbances caused
by blockage of the fuel filter.
• The filter cannot be cleaned but must be replaced with a new
filter when it blocked. The filter should be changed at least
once per year.

Air filter

The air filter should be cleaned regularly removing dust and dirt
to avoid:
• Carburettor malfunction
• Starting problems
• Reduced engine power
• Unnecessary wear to
engine parts
The air filter system consists
of a backup filter (1) and a
main filter (2):
1) The main filter is an oiled
foam rubber filter that is
easily accessible under the
filter cover (A). In dusty
conditions this filter should
be inspected/replaced each
week. In order to obtain a
good filtering effect, the filter
must be cleaned and oiled
regularly. Special
HUSQVARNA oil has been
produced for this purpose.
• Remove the filter. Wash the
filter carefully in tepid,
soapy water. After cleaning
rinse the filter thoroughly in
clean water. Squeeze out
the filter and let the filter
dry.
NOTE! Compressed air at a
high pressure can damage
the foam.
• Oil the filter carefully. It is
extremely important that the
entire filter is saturated in
oil.
2) The backup filter is a paper filter accessible from under
cover B. This filter should be replaced/cleaned when the
engine's power drops or each month. The filter is cleaned
by shaking or by careful blowing with compressed air. Note
that the filter must not be washed!
A filter used for a long period of time can never be completely
cleaned. Therefore all air filters must be replaced periodically
with a new filter. A damaged air filter must always be
replaced.
IMPORTANT INFORMATION!
Insufficient care of the air filter will cause deposits on
the spark plug resulting in abnormal wear to engine
parts.
