GENERAL SAFETY PRECAUTIONS
Vibration damping system
Your machine is equipped with a vibration damping system
that is designed to minimize 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.
Stop switch
Use the stop switch to switch off the engine.
Muffler
The muffler is designed to keep noise levels to a minimum and
to direct exhaust fumes away from the user.
In areas with a hot, dry climate there is a high risk of fires.
These areas are sometimes subject to government rules
requiring among other things the muffler must be equipped
with an approved type of spark arrestor mesh.
For mufflers it is very important that you follow the instructions
on checking, maintaining and servicing your machine. See
instructions under the heading Checking, maintaining and
servicing the machine’s safety equipment.
Cutting equipment
This section describes how to choose and maintain your
cutting equipment in order to:
• Reduce the risk of kickback.
• Reduce the risk of the saw chain breaking or jumping off
the bar.
• Obtain optimal cutting performance.
• Extend the life of cutting equipment.
• Avoid increasing vibration levels.
General rules
• Only use cutting equipment recommended by us!
See instructions under the heading Technical data.
• Keep the chain’s cutting teeth properly sharpened!
Follow our instructions and use the recommended file
gauge. A damaged or badly sharpened chain increases
the risk of accidents.
!
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.
!
WARNING! The exhaust fumes from the
engine are hot and may contain sparks which
can start a fire. Never start the machine
indoors or near combustible material!
CAUTION! The muffler gets very hot during and after use.
This also applies during idling. Be aware of the fire hazard,
especially when working near flammable substances and/
or vapours.
!
WARNING! Never use a saw without a muffler,
or with a damaged muffler. A damaged muffler
may substantially increase the noise level and
the fire hazard. Keep fire fighting equipment
handy. If a spark arrestor screen is required in
your area, never use the saw without or with a
broken spark arrestor screen.
