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 the air filter-cover and unscrew the filter.

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

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. Some mufflers are equipped with a special screen.

If your saw has this type of muffler, you should clean the screen at least once a week. This is done with a wire brush.

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

Needle bearing maintenance

•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.

Spark plug

The spark plug condition is influenced by:

The clutch drum is equipped with one of the following chain sprockets:

•Spur sprocket (A) (the chain sprocket is welded on the drum)

•Rim sprocket (B) (exchangeable)

Both versions have buit-in needle bearing at the drive shaft, whitch has to be greased regularly (once a week).

NOTE! Use only high quality bearing grease or engine oil.

•	An incorrect carburetor setting.
•	Wrong fuel mixture (too much oil in the gasoline).

Adjustment of the oil pump

• 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	0,5 mm
	power, difficult to start or	0,5 mm
	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 (0,020"). The spark
	plug should be replaced after

The oil pump is adjustable. Ad- justments are made by turning the screw using a screwdriver or combination spanner. The saw is supplied from the factory set to 1 turn open. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.

–

about a month in operation or

earlier if the electrodes are

badly eroded.

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

WARNING! The engine must not be running when making adjustments.

Recommended settings:

Bar -15": 1 turn from the closed position.

Bar 15"-18": 2 turns from the closed position.

Bar 18"-24": 3 turns from the closed position.

Bar 24"- : 4 turns from the closed position.

These recommendations apply to Jonsered’s chain oil, for other chain oil increase the oil flow by one step.
