Husqvarna K1250 manual Fuel filter, Air filter, Fine adjustment of the idle speed T

MAINTENANCE

Fine adjustment of the idle speed T

Adjust the idle speed using the T screw. When an adjustment is necessary, first turn the screw clockwise until the blade starts to rotate. Now turn the screw anti-clockwise until the blade stops rotating. A correctly adjusted idle speed is set when the engine accelerates without hesitation.

Rec. idle speed: 2500 rpm

WARNING! If the idle speed cannot be

!adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.

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 located inside the tank.

•The filter cannot be cleaned but must be replaced with a new filter when it is clogged. The filter should be changed at least once per year.

Air filter

Air filters must be regularly cleaned to remove dust and dirt in order to avoid:

•Carburettor malfunctions

•Starting problems

•Loss of engine power

•Unnecessary wear to engine parts

•Excessive fuel consumption.

The air filter system consists of an oiled foam plastic filter (1) and a paper filter (2):

1The foam plastic filter is easily accessible under the filter cover A. This filter should be checked weekly and replaced if necessary. In order to obtain a good filtering effect, the filter must be replaced regularly or cleaned and oiled. A special HUSQVARNA oil has been produced for this purpose.

B

Remove the foam plastic filter. Wash the filter well in tepid soapy water. After cleaning, rinse the filter well in clean water. Squeeze out and allow the filter to dry. NOTE! High pressure compressed air can damage the foam.

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.

2The paper filter is accessible under cover B. This filter must be replaced/cleaned when the engine’s power drops or after one-two weeks. The filter is cleaned by shaking or by careful blowing with compressed air. Note that the filter must not be washed.

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.

IMPORTANT INFORMATION

Poor maintenance of the air filter will cause carbon build-up on the spark plug and abnormal wear to engine parts.
