17. Use extreme caution when cut- ting small size brush and sap- lings because slender material may catch the saw chain and be whipped toward you or pull you off balance.
18.When cutting a limb that is un- der tension, be alert for spring- back so that you will not be struck when the tension in the
wood fibers is released.
19. Never cut in high wind, bad weather, when visibility is poor or in very high or low temperatures. Always check the tree for dead branches which could fall during the felling operation.
20.Keep the handles dry, clean and free of oil or fuel mixture.
21.Operate the chain saw only in
well ventilated areas. Never start or run the engine inside a closed room or building. Exhaust fumes contain dangerous carbon mon- oxide.
22.Do not operate the chain saw in a tree unless specially trained to
do so.
23. Guard against kickback. Kick-
back is the upward motion of the
guide bar which occurs when the
saw chain at the nose of the
guide bar contacts an object.
Kickback can lead to dangerous loss of control of the chain saw.
24. When transporting your chain saw, make sure the appropriate guide bar scabbard is in place.
KICKBACK SAFETY PRECAU-
TIONS FOR CHAIN SAW USERS
WARNING
•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 con- tact in some cases may cause a lightning fast reverse reac-

tion, 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 | G |
to lose control of the saw, | B |
which could result in serious |
|
personal injury. |
|
• Do not rely exclusively on the |
|
safety devices built into your |
|
saw. As a chain saw user you |
|
should take several steps to |
|
keep cutting jobs free from ac- |
|
cident or injury. |
|
(1) With a basic understanding of |
|
kickback you can reduce or |
|
eliminate the element of surprise. |
|
Sudden surprise contributes to |
|
accidents. |
|
(2) Keep a good grip on the saw with |
|
both hands, the right hand on the |
|
rear handle, and the left hand on |
|
the front handle, when the engine |
|
is running. Use a firm grip with |
|
thumbs and fingers encircling |
|
the chain saw handles. A firm |
|
grip will help you reduce kick- |
|
back and maintain control of the |
|
saw. |
|
(3)Make certain that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.
(4)Cut at high engine speeds.
(5) Do not overreach or cut above shoulder height.
(6)Follow the manufacturer’s sharp- ening and maintenance instruc- tions for the saw chain.
(7) Only use replacement bars and chains specified by the manufac- turer or the equivalent.
