Causesand Operator Prevention Of Kickback - Craftsman 98023 Manual De Instrucciones

chain saw forcutting
plastic, masonry or non-wood building materials. Use of the chain saw
for operations different than intended could result in a hazardous situation.
CAUSESAND 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 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, ff proper precautions are taken. Do not let go of
the chain saw.
• Do not overreach and do not cut above chest 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.
THE FOLLOWING PRECAUTIONSSHOULDBE FOLLOWEDTO MiNiMiZE KICKBACK:
(1.) Grip Saw Firmly. Hold the chain saw firmly with both hands when the motor is running. Use a
firm grip with thumbs and fingers encircling the chain saw handles. Chain saw will pull forward when
cutting on the bottom edge of the bar, and push backward when cutting along the top edge of the bar.
(2.) Do not over reach.
(3.) Keep proper footing and balance at all times.
(4.) Don't let the nose of the guide bar contact a log, branch, ground or other obstruction.
(5.) Don't cut above shoulder height.
(6.) Use devices such as low kickback chain and reduced kickback guide bars that reduce the risks
associated with kickback.
(7.) Only use replacement bars and chains specified by the manufacturer or the equivalent.
(8.) Never let the moving chain contact any object at the tip of the guide bar.
(9.) Keep the working area free from obstructions such as other trees, branches, rocks, fences,
stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting
through a particular log or branch.
(10.) Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the
chance of kickback. Check tension at regular intervals with the motor stopped and tool unplugged,
never with the motor running.
(11.) Begin and continue cutting only with the chain moving at full speed. If the chain is moving at a
slower speed, there is a greater chance for kickback to occur.
(12.) Cut one log at a time.
(13.) Use extreme caution when re-entering a previous cut. Engage ribbed bumpers into wood and
allow chain to reach full speed before proceeding with cut.
(14.) Do not attempt plunge cuts or bore cuts.
(15.) Watch for shifting logs or other forces that could close a cut and pinch or fall into chain.

The following features are included on your saw to help reduce the hazard of
kickback; however such features will not totally eliminate this dangerous reaction. As a chain saw user
