STARTING AND STOPPING

Reactivate the chain brake by pushing the front hand guard
back towards the front handle. The chain saw is now ready for
use.

•

Never start a chain saw unless the bar, chain and all
covers are fitted correctly. See instructions under the
heading Assembly. Without a bar and chain attached to
the chain saw the clutch can come loose and cause
serious injury.

•

The chain brake should be activated when starting. Se
instructions under the heading Start and stop. Do not drop
start. This method is very dangerous because you may
lose control of the saw.

•

Never start the machine indoors. Exhaust fumes can be
dangerous if inhaled.

•

Observe your surroundings and make sure that there is no
risk of people or animals coming into contact with the
cutting equipment.

•

Always hold the saw with both hands. The right hand
should be on the rear handle, and the left hand on the front
handle. All people, whether right or left handed, should
use this grip. Use a firm grip with thumbs and fingers
encircling the chain saw handles.

Stopping

The engine is stopped by pushing the stop switch to the stop
position.

!

WARNING! Long term inhalation of the
engine’s exhaust fumes, chain oil mist and
dust from sawdust can represent a health
risk.
