Additional Safety Instructions - Makita DUC357 Instruction Manual

4. Wear eye protection. Further protective equip-
ment for hearing, head, hands, legs and feet is
recommended. Adequate protective equipment
will reduce personal injury from flying debris or
accidental contact with the saw chain.
Do not operate a chain saw in a tree, on a lad-
5.
der, from a rooftop, or any unstable support.
Operation of a chain saw in this manner could
result in serious personal injury.
Always keep proper footing and operate the
6.
chain saw only when standing on fixed, secure
and level surface. Slippery or unstable surfaces
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 the bar and chain.
Improperly tensioned or lubricated chain may
either break or increase the chance for kickback.
11. Cut wood only. Do not use chain saw for pur-
poses not intended. For example: do not use
chain saw for cutting metal, plastic, masonry
or non-wood building materials. Use of the
chain saw for operations different than intended
could result in a hazardous situation.
12. Do not attempt to fell a tree until you have an
understanding of the risks and how to avoid
them. Serious injury could occur to the operator or
bystanders while felling a tree.
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
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 chain saw 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 precau-
tions are taken. Do not let go of the chain
saw.

• Do not overreach and do not cut above
shoulder height. This helps prevent unin-
tended tip contact and enables better control
of the chain saw in unexpected situations.
• Only use replacement guide bars and saw
chains specified by the manufacturer.
Incorrect replacement guide bars and saw
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. Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is off and the battery
pack is removed. Unexpected actuation of the
chain saw while clearing jammed material or
servicing may result in serious personal injury.
