5. For safe operation

16.Always shut off the engine before setting it down.

17.Use extreme caution when cutting small size brush and saplings 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 under 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 monoxide.

22.Do not operate the chain saw in a tree unless specially trained to do so.

23.Guard against kickback. Kickback 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 PRECAUTIONS 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 contact in some cases may cause a lightning fast 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 Iose control of the saw, which could result in serious personal injury.
