MAINTENANCE

Air filter

The air filter (A) must be cleaned regularly to remove dust and dirt. This will prevent:

Carburetor malfunctions

 

Starting problems

 

Reduced performance

B A

Unnecessary wear on engine parts

Abnormal fuel consumption

Elevated content of harmful exhaust fumes

Clean the filter after 25 hours of operation or more often if the air is exceptionally dusty in the work area.

To clean the air filter

Dismantle the air filter cover (B) and remove the filter medium. Wash it clean in a solution of soap and warm water. Make sure that the filter is dry before reassembling.

An air filter, which has been used for some time, can- not be cleaned completely. Therefore,the filter must be replaced by a new one at regular intervals. A faulty filter must always be replaced.

Spark plug

The condition of the spark plug is influenced by:

An incorrectly adjusted carburetor.

Wrong fuel mixture (too much oil in the gasoline).

Poor quality gasoline and/or oil.

A dirty air filter.

These factors cause deposits on the spark plug electrodes, which may result in malfunction and difficulty starting the blower.

If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first.

The spark plug is accessible under the cylinder shrouding, which can be removed by unscrewing four screws.

If the spark plug is clogged, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.5 mm (0.020”). The spark plug should be replaced after about one month of operation or earlier if the electrodes are badly eroded.

NOTE! Always use the recommended type of spark plug! See under ”Technical data”. An incorrect spark plug can severely damage the piston/cylinder.

0,5 mm
