4. For safe operation
16.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.
17.Do not operate a chain saw in a tree unless specially trained to do so.
18.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.
19.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 lose control of the saw 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 accident 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 kickback and maintain control of the saw. Don’t let go.
(3)Make certain that the area in which you’re 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 manufacturers sharpening and maintenance instructions for saw chain.
(7)Only use replacement bars and chains specified by the manufacturer or the equivalent.
