■ When cutting a limb that is under tension
be alert for spring back. When the tension
in the wood fibres is released the spring
loaded limb may strike the operator and/or
throw the chain saw out of control.
■ Use extreme caution when cutting brush
and saplings. The slender material may
catch the saw chain and be whipped toward
you or pull you off balance.
■ Carry the chain saw by the front handle
with the chain saw switched off and away
from your body. When transporting or
storing the chain saw always fit the guide
bar cover. Proper handling of the chain saw
will reduce the likelihood of accidental
contact with the moving saw chain.
■ Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chains
may either break or increase the chance for
kickback.
■ Keep handles dry, clean, and free from oil
and grease. Greasy, oily handles are
slippery causing loss of control.
■ Cut wood only. Do not use chain saw for
purposes not intended. For example: do
not use chain saw for cutting plastic,
masonry or non-wood building materials.
Use of the chain saw for operations other
than intended could result in a hazardous
situation.
5 CAUSES AND OPERATOR
PREVENTION OF KICKBACK
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and
back towards the operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards
the operator.
Either of these reactions may cause you to lose
control of the saw which could result in serious
personal injury. Do not rely exclusively upon the
safety devices built into your saw. As a chain saw
user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
■ Maintain a firm grip, with thumbs and fingers
encircling the chain saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces.
Kickback forces can be controlled by the
operator, if proper precautions are taken. Do
not let go of the chain saw.
■ Do not overreach and do not cut above
shoulder height. This helps prevent
unintended tip contact and enables better
control of the chain saw in unexpected
situations.
■ Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause
chain breakage and/or kickback.
■ Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead
to increased kickback.
6 VIBRATION LOAD
WARNING!
Danger due to vibration
The actual magnitude of the vibration
emissions during the use of the
appliance may deviate from that stated
by the manufacturer. Observe the
following influencing factors before or
during use:

tool installed?
■
Are the handle grips and any
optional vibration grips mounted,
and are they firmly attached to the
appliance?
■ Only operate the tool at the motor speed
required for the respective work. Avoid using
the maximum speed in order to reduce noise
and vibrations.
