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.

Recommended settings:

Bar 13"-15": Position 1

Bar 15"-18": Position 2

Bar 18"-20": Position 3

WARNING! The engine must not be running

!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.
