MAINTENANCE

Spark plug

The spark plug condition is influenced by:

Incorrect carburetor adjustment.

An incorrect fuel mixture (too much or incorrect type of oil).

A dirty air filter.

Adjustment of the oil pump

The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.

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

If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0.5 mm). The spark plug should be replaced after about a month in operation or earlier

if necessary.

Note! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is fitted with a suppressor.

Lubricating the bar tip sprocket

Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease.

Needle bearing lubrication

The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil. See instructions under the heading Cutting equipment.

Recommended settings:

Bar 13"-15": Position 1

Bar 15"-18": Position 2

Bar 18"-20": Position 3

WARNING! The engine must be stopped

!when making adjustments.

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1Air intake on the starter.

2Air guide plate.

3Fins on the flywheel.

4Cooling fins on the cylinder.

5Cylinder cover (directs cold air over the cylinder).

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

Note! The cooling system on a chain saw with catalytic converter must be cleaned daily. This is particularly important on chain saws with catalytic converters, because the higher exhaust temperature requires efficient cooling of the engine and the catalytic converter unit.
