In this section the machine’s safety features and their 
function are explained. For inspection and maintenance 
see instructions under the heading Checking, maintaining 
and servicing chain saw safety equipment. See 
instructions under the heading, What is what?, to find 
where these parts are located on your machine.

The life span of the machine can be reduced and the risk 
of accidents can increase if machine maintenance is not 
carried out correctly and if service and/or repairs are not 
carried out professionally. If you need further information 
please contact your nearest service workshop.

Your chain saw is equipped with a chain brake that is 
designed to stop the chain 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 (45). 
• The chain brake (A) can either be activated manually 

(by your left hand) or automatically by the inertia release 
mechanism.(3)

• The brake is applied when the front hand guard (B) is 

pushed forwards or when the right-hand brake trigger 
(E) is pushed up and forwards (240e TrioBrake). (3)

• This movement activates a spring-loaded mechanism 

that tightens the brake band (C) around the engine drive 
system (D) (clutch drum). (4)

• The front hand guard is not designed solely to activate 

the chain brake. Another important feature is that it 
reduces the risk of your left hand hitting the chain if you 
lose grip of the front handle.

• The chain brake must be engaged when the chain saw 

is started to prevent the saw chain from rotating.

• Use the chain brake as a ”parking brake” when starting 

and when moving over short distances, to reduce the 
risk of moving chain accidentally hitting your leg or 
anyone or anything close by.

• To release the chain brake pull the front hand guard 

backwards, towards the front handle.

• 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.

• The way the chain brake is activated, either manually or 

automatically by the inertia release mechanism, 
depends on the force of the kickback and the position of 
the chain saw in relation to the object that the kickback 
zone of the bar strikes.
If you get a violent kickback while the kickback zone of 
the bar is farthest away from you the chain brake is 
designed to be activated by the inertia in the kickback 
direction.
If the kickback is less violent or the kickback zone of the 
bar is closer to you the chain brake will be activated 
manually by the movement of your left hand.

• In the felling position the left hand is in a position that 

makes manual activation of the chain brake impossible. 
With this type of grip, that is when the left hand is placed 
so that it cannot affect the movement of the front hand 
guard, the chain brake can only be activated by the 
inertia action.  

No. It takes a certain force to move the hand guard forward. 
If your hand only lightly touches the front guard or slips 
over it, the force may not be enough to trigger the chain 
brake. You should also maintain a firm grip of the chain saw 
handles while working. If you do and experience a 
kickback, your hand may never leave the front handle and 
will not activate the chain brake, or the chain brake will only 
activate after the saw has swung around a considerable 
distance. In such instances, the chain brake might not have 
enough time to stop the saw chain before it touches you.

There are also certain positions in which your hand cannot 
reach the front hand guard to activate the chain brake; for 
example, when the saw chain is held in felling position.

IMPORTANT! Sparks can come from the muffler, the 
bar and chain or other sources. Always have fire 
extinguishing tools available if you should need them. 
Help prevent forest fires.
