4. Wear safety glasses and hearing protection. Fur-
ther 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.
5. Do not operate a chain saw in a tree. Operation of
a chain saw while up in a tree may result in personal
injury.
6. 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 con-
trol of the chain saw.
7. 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 con-
trol.
8. 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 bal-
ance.
9. 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.
10. Follow instructions for lubricating, chain ten-
sioning and changing accessories. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
11. Keep handles dry, clean, and free from oil and
grease. Greasy, oily handles are slippery causing
loss of control.
12. Cut wood only. Do not use chain saw for pur-
poses 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.
13. 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 con-
trol 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 shoul-
der height. This helps prevent unintended tip
contact and enables better control of the chain
saw in unexpected situations.
- Only use replacement bars and chains speci-
fied 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.
14. 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 cor-
rectly;
• The chain has been sharpened and tensioned in
accordance with the regulations;
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 per-
sonal injury and damage to objects around the oper-
ator.
