SAFETY INSTRUCTIONS

1 Chain brake and front hand guard

YOUR chain saw is equipped with a chain brake that is desig- ned to stop the chain immediately if you get a kickback.

The chain brake reduces the risk of accidents, but only You can prevent them.

Take care when using your saw and make sure the kickback zone of the bar never touches any object.

3a Starting

The chain brake should be activated when starting.

b You can also use the

chain brake as a

temporary brake when you

change position or if you

put the saw down for a

short time. You should

also apply the chain brake

manually if there is a risk

of the chain accidentally

hitting anyone or anything

1The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism (a free- swinging pendulum). On most of our models the front hand guard acts as a counterweight in case of kickback.

The brake is applied when the front hand guard (B) is pushed forwards.

This movement activates a spring-loaded mechanism that tightens the Brake Band (C) around the engine drive system (D) (Clutch Drum).

close by.

4To release the chain brake pull the front hand guard backwards, towards the front handle.

5As mentioned in section A, kickback can be very sudden and violent.

Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw firmly and not let go.

2The front hand guard is not designed solely to activate the chain brake. Another important safety feature is that it prevents the chain from hitting your left hand if you lose your grip on the front handle.
