flying debris or accidental contact with the saw
chain.
5. Before starting work, check that the chain saw is in
proper working order and that its condition
complies with the safety regulations. Check in
particular that:
The chain brake is working properly;
•
The run-down brake is working properly;
•
The bar and the sprocket cover are fitted
•
correctly;
The chain has been sharpened and tensioned
•
in accordance with the regulations;
6. Do not operate a chain saw in a tree. Operation
of a chain saw while up in a tree may result in
personal injury.
7. 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.
8. 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.
9. 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.
10. 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.
11. Follow instructions for lubricating, chain
tensioning and
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
12. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
13. 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.
14. 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
changing accessories.
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.

shoulder
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.
15. Do not start the chain saw with the chain cover
being installed on it.Starting the chain saw with
the chain cover being installed on it may cause the
chain cover to thrown out forward resulting in
personal injury and damage to objects around the
operator.
