Do not use the saw in bad weather, such as dense fog,

weather is tiring and often brings added risks, such as icy

ground, unpredictable felling direction, etc.

Take great care when removing small branches and avoid

cutting bushes (i.e. cutting many small branches at the

MAINTENANCE

Needle bearing maintenance

Winter use

During winter time, powder snow and cold weather can cause

running problems, such as:

• Too low engine temperature.

• Icing on the air filter and carburettor.

The clutch drum is equipped

with one of the following chain

Therefore some special measures are required:

sprockets:

• Partly reduce the air inlet of the starter and by doing that

increase the engine temperature.

• Preheat the intake air to the carburettor by removing the
