MAINTENANCE

Consequently, never work in an enclosed or badly ventilated area. Good air circulation should always prevail when working in snowy hollows, ravines or in confined conditions.

WARNING! The catalytic converter muffler

!gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.

Needle bearing lubrication

The clutch drum is fitted with one of the following drive sprockets:

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

•B Rim sprocket (replaceable)

Both versions have a needle bearing on the drive shaft, which has to be greased regularly (once a week).

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

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.

Recommended settings:

Bar 13"-15": Position 1

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.

”Air Injection” 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.
