2. Always hold the chain saw with your right
hand on the rear handle and your left hand on
the front handle.
Holding the chain saw with a
reversed hand configuration increases the risk of
personal injury and should never be done.
3. Wear safety glasses and hearing protection.
Further protective equipment for head, hands,
legs and feet is recommended.
Adequate
protective clothing will reduce personal injury by
flying debris or accidental contact with the saw
chain.
4. Do not operate a chain saw in a tree. Operation
of a chain saw while up in a tree may result in
personal injury.
5. Always keep proper footing and operate the
chain saw only when standing on fixed, secure
and level surface.
Slippery or unstable surfaces
such as ladders may cause a loss of balance or
control of the chain saw.
6. 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.
7. 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.
8. 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.
9. Follow instructions for lubricating, chain
tensioning and changing accessories.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
10. Keep handles dry, clean, and free from oil and
grease.
Greasy, oily handles are slippery causing
loss of control.
11. 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 different than intended could
result in a hazardous situation.
12. 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.
ADDITIONAL SAFETY RULES
1. Read the instruction manual in order to familiarize
yourself with operation of the chain saw.
2. Before using the chain saw for the first time,
arrange to have instruction in its operation. If this
is not possible, at least practice cutting round
timber on a trestle before beginning work.
3. The chain saw must not be used by children or
young persons under 18 years of age. Young
persons over 16 years of age may be exempted
from this restriction if they are undergoing training
under the supervision of an expert.
