GENERAL SAFETY PRECAUTIONS
10 – English
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.  
Will my hand always activate the chain 
brake during a kickback?
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.
Will my inertia activated chain brake 
always activate during kickback in the 
event of a kickback?
No. First your brake must be in working order. Testing the 
brake is simple, see instructions under the heading 
Checking, maintaining and servicing chain saw safety 
equipment. We recommend you do before you begin each 
work session. Second the kickback must be strong 
enough to activate the chain brake. If the chain brake is 
too sensitive it would activate all the time which would be 
a nuisance.
Will my chain brake always protect me 
from injury in the event of a kickback?
No. First, the chain brake must be in working order to 
provide the intended protection. Second, it must be 
activated during the kickback as described above to stop 
the saw chain. Third, the chain brake may be activated but 
if the bar is too close to you the brake might not have 
enough time to slow down and stop the chain before the 
chain saw hits you.
Only you and proper working technique can eliminate 
kickback and its danger.
Throttle lockout
The throttle lockout is designed to prevent accidental 
operation of the throttle control. When you press the lock 
(A) (i.e. when you grasp the handle) it releases the throttle 
control (B). When you release the handle the throttle 
control and the throttle lockout both move back to their 
original positions. This arrangement means that the 
throttle control is automatically locked at the idle setting.
Chain catcher
The chain catcher is designed to catch the chain if it snaps 
or jumps off. Replace it if necessary with an aluminium 
chain catcher (is available as spare part). This should not 
happen if the chain is properly tensioned (see instructions 
under the heading Assembly) and if the bar and chain are 
properly serviced and maintained (see instructions under 
the heading General working instructions).
