GENERAL SAFETY PRECAUTIONS
Will my inetria 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 to 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 lock
The throttle lock 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 lock 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. 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).
Right hand guard
Apart from protecting your hand if the chain jumps or snaps,
the right hand guard stops branches and twigs from
interfering with your grip on the rear handle.
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to reduce vibration and make operation
easier.
The machine's vibration damping system reduces the transfer
of vibration between the engine unit/cutting equipment and
the machine's handle unit.
The body of the chain saw, including the cutting equipment, is
insulated from the handles by vibration damping units.
Cutting hardwoods (most broadleaf trees) creates more
vibration than cutting softwoods (most conifers). Cutting with
cutting equipment that is blunt or faulty (wrong type or badly
sharpened) will increase the vibration level.
WARNING! Overexposure to vibration can
!
lead to circulatory damage or nerve damage
in people who have impaired circulation.
Contact your doctor if you experience
symptoms of overexposure to vibration.
Such symptoms include numbness, loss of
feeling, tingling, pricking, pain, loss of
strength, changes in skin colour or
condition. These symptoms normally appear
in the fingers, hands or wrists. These
symptoms may be increased in cold
temperatures.
Stop switch
Use the stop switch to switch off the engine.
