•   The chain brake may be activated manually or by the force 

of inertia depending on the strength of the kickback and 

the position of the saw in relation to the object which made 

contact with the kickback danger zone.

  

-  If the kickback is suffi ciently violent and the left hand   

  is too far from the kickback guard, the chain brake is     

  activated by the INERTIA of the chain brake against the  

  force of the kickback.

  

-  In the event of smaller kickbacks or when the left hand  

  is near the kickback guard, the chain brake is activated  

   manually with the left hand.

•   When the chain saw is turned on its side and the operator 

is holding the side of the front handle, the kickback guard 

will not strike the left hand in the event of a kickback and 

will thus not activate the chain brake. In a situation of this 

type, inertia is the only thing that can activate the chain 

brake, but like manual activation, it will not work in every 

situation.

Kickback guard inspection

•   Inspect kickback guard for visible defects, such as cracks.

•   Move kickback guard back and forth to ensure that it moves 

freely without being loose.

Manual chain brake function check

•   Check chain brake daily or every time the saw is used. 

Holding the running saw fi rmly with the left hand on the 

front handle and the right hand on the rear handle, twist 

your left wrist, pushing the kickback guard to activate the 

chain brake without letting go of the front handle. The chain 

should stop instantaneously. 

If the chain brake does not 

perform as required, have it serviced by authorized per-
sonnel.

Inertia chain brake function check

•   Hold the running saw level with the guide bar approximately 

45 cm above a stump or other solid wooden object. 

  

Release the power trigger.

•   Release the front handle, letting 

 

  the chain saw pivot in your 

right hand as the guide bar falls 

down and strikes the stump. 

The brake should activate when 

the bar nose hits the stump.

Your chain saw is equipped with a chain brake designed to 

stop the chain instantaneously in the event of a kickback. 

A chain brake can reduce the risk of accident, but only the 

 operator can prevent accidents from happening. Be extremely 

careful when operating a chain saw and do not allow the kick-

back danger zone to make contact with anything.

•   The chain brake (A) is activated either manually (with the left 

hand) or by the force of inertia (the inertia of the kickback 

guard resisting the motion of the saw from the force of the 

kickback). However it is activated, the kickback protection 

mechanism works in the opposite direction to the force of 

the kickback. The saw incorporates a slip clutch which pro-

tects the saw against overload. If the chain stops while the 

motor is running, the saw is overloaded. Ease up on the 

cutting pressure until the chain starts running again. If the 

saw jams in the tree, stop the saw immediately and free it.

•   The chain brake is also activated when the kickback guard 

(B) is pushed forward. This releases a springloaded mecha-

nism which jerks the brake band tightly around the brake 

drum.

•   The purpose of the kickback guard is not only to  activate 

the chain brake. Its other important function is to reduce 

the danger of contact with the chain in the event that the 

operator loses his grip on the front handle.

•   Use the chain brake as a «parking brake» when carrying 

the chain saw around or putting it down for short periods! 

Besides automatic activation in the event of a kickback, the 

chain brake may also be activated manually and must be 

activated in the event of any inadvertent contact with a ro-

tating chain.

•   An activated chain brake is released by pulling the kickback 

guard back towards the front handle.

•   As pointed out on page 7, a kickback can be extremely 

 violent and lightning-fast. Most kickbacks are small and do 

not activate the chain brake. When this happens, it is im-

portant to maintain a fi rm grip on the saw and not let go.
