MAINTENANCE

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.

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.

2 Air guide plate.

3 Fins on the flywheel.

4 Cooling fins on the cylinder.

5 Cylinder 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.

”Dust Free” centrifugal cleaning

Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan.

IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburettor compartment.

Winter use

Running problems can occur when using the machine in the cold and snowy conditions caused by:

•Too low engine temperature.

•Icing of the air filter and carburettor.

Special measures are therefore often required:

•Preheat the intake air to the carburettor by using the heat from the cylinder.

•Partly mask the air inlet on the starter to increase the working temperature of the engine.

Temperature 0°C or colder:

The cylinder cover is designed so it can be adjusted for running in cold weather. Twist the winter flap so that preheated air from the cylinder can pass into the carburettor space preventing icing of the air filter, etc.

IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
