KICKBACK SAFETY PRECAUTIONS
Warning – Kickback may occur when the nose or tip of the
guide bar touches on object, or when the wood closes in the
cut. Tip contact in some cases may cause a lightning fast
reverse reaction, kicking the guide bar up and back towards
the operation. 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 injury to user.
Kickback is the name given to a sudden, rapid upward movement of the saw cutting mechanism in an upward
arc towards the operator. Kickback occurs when the upper quadrant of the bar nose comes in contact with a
solid object or is pinched. The rotational force of the chainsaw can be reversed in the opposite direction of the
chain movement. This may ing the bar up and back in an arc towards the operator. Serious injury or even
death can result from contact between the moving saw chain and the operator.
The best protection against injury due to kickback is to avoid situations that can cause kickback:
- Hold the chainsaw rmly with both hands and maintain a secure grip.
- Be aware of the location of the bar nose at all times while cutting.
- Never bring the nose of the guide bar in contact with any object. Never cut limbs with the nose of the guide
bar. Be especially careful when cutting saplings, brush and small hard limbs that may easily pinch the cutting
chain.
- Don’t cut above shoulder height. Don’t overreach or use the chainsaw while standing on a ladder or tree.
- Never use the chainsaw one-handed.
- Begin and continue cutting at full throttle.
- Use extreme caution when entering a previous cut.
- Do not attempt plunge cuts if you are not familiar with this cutting technique.
- Stand to the side of the cutting path of the chainsaw.
- Cut with a correctly sharpened, properly tensioned chain at all times.
Save these instructions. It is your guide to safe and proper operation of this chain saw.
