30. Keep handles dry, clean and free from oil and
grease.
Cordless Chain saw safety
warnings:
1. Keep all parts of the body away from the saw
chain when the chain saw is operating. Before you
start the chain saw, make sure the saw chain is
not contacting anything. A moment of inattention
while operating chain saws may cause entanglement
of your clothing or body with the saw chain.
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. Hold the power tool by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring. Saw chains contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
4. 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.
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 control 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 control.
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
balance.
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
tensioning 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 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.
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.
GEB039-2 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. (Fig. 1)
- 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.
SAVE THESE INSTRUCTIONS.
