MAINTENANCE

Air filter

The air filter must be regularly cleaned from dust and dirt in order to avoid:

•Carburetor malfunctions

•Starting problems

•Engine power reduction

•Unnecessary wear on the engine parts

•Abnormal fuel consumption

Clean the air filter daily or more often if the air is exceptionally dusty in the working area.

•Disassemble the air filter by removing its cover and take

out the filter. When reassembling, make sure that the filter is tight against the filter holder. Clean the filter by brushing or shaking it.

•A more thorough cleaning of the filter is obtained by washing it in water and soap.

An air filter, which is used for some time, cannot be cleaned completely. Therefore it must be replaced by a new one, with regular intervals.

IMPORTANT! A damaged air filter must always be replaced.

Muffler

The muffler is designed in order to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material. The muffler is equipped with a spark arrestor mesh. The mesh must be cleaned at least once a week. This is done with a wire brush.

CAUTION! The spark arrestor mesh must be replaced, if damaged. The saw will be overheated, if the mesh is clogged. This results in damage on the cylinder and the piston. Never use a saw with a clogged or defective muffler.

Spark plug

The spark plug condition is influenced by:

•An incorrect carburetor setting.

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

•A dirty air filter.

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

If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Readjust if necessary. The correct gap is 0,5 mm (.02"). The spark plug should be replaced after about a month in operation or earlier if the electrodes are badly eroded.

0,5 mm

IMPORTANT! Always use the recommended spark plug type. An incorrect spark plug can severely damage the piston/ cylinder.
