It is not possib

 

le to cover every conceivable situation you 

can face when using a chain saw. Always exercise care 
and use your common sense. Avoid all situations which 
you consider to be beyond your capability.  If you still feel 
uncertain about operating procedures after reading these 
instructions, you should consult an expert before 
continuing. Do not hesitate to contact your dealer or us if 
you have any questions about the use of the chain saw. We 
will willingly be of service and provide you with advice as 
well as help you to use your chain saw both efficiently and 
safely. Attend a training course in chain saw usage if 
possible. Your dealer, forestry school or your library can 
provide information about which training materials and 
courses are available. Work is constantly in progress to 
improve the design and technology - improvements that 
increase your safety and efficiency. Visit your dealer 
regularly to see whether you can benefit from new features 
that have been introduced.

• Approved protective helmet

• Hearing protection

• Protective goggles or a visor

• Gloves with saw protection

• Trousers with saw protection

• Boots with saw protection, steel toe-cap and non-slip 

sole

• Always have a first aid kit nearby.

• Fire Extinguisher and Shovel

Generally clothes should be close-fitting without restricting 
your freedom of movement.

′s safety equipment

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 servicing dealer.

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.

• 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. (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 is designed to 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.  

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.
