SAFETY INSTRUCTIONS
it cannot affect the movement of the front hand guard, the
chain brake can only be activated by the inertia of the
counterweight.
• The inertia activated chain brake is a valuable feature but
there are certain factors to remember (see point above).
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
movement is controlled by two independent return springs.
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.
When you use a chain saw, vibration is generated by the
uneven contact between the chain and the wood you are
cutting.
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. See instructions
under the heading Cutting equipment.
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.
Stop switch
Use the stop switch to switch off the engine.

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. The risk
increases at low temperatures.
