KICKBACK

See Figures 1 - 4.

 WARNING: Kickback may occur when the

moving chain contacts an object at the upper

portion of the tip of the guide bar or when the

wood closes in and pinches the saw chain in

the cut. Contact at the upper portion of the tip

of the guide bar can cause the chain to dig into

the object and stop the chain for an instant.

The result is a lightning fast, reverse reaction

which kicks the guide bar up and back toward

the operator. If the saw chain is pinched along

the top of the guide bar, the guide bar can be

driven rapidly back toward the operator. Either

of these reactions can cause loss of saw control

which can result in serious injury. Do not rely

exclusively upon the safety devices built into

the saw. As a chain saw user, you should take

several steps to keep your cutting jobs free from

accident or injury.

 The following precautions should be followed

to minimize kickback:

• Always grip the saw firmly with both hands.

Hold the saw firmly with both hands when

the unit is running. Place your right hand on

the rear handle and your left hand on the

front handle with your thumbs and fingers

encircling the chain saw handles. A firm grip

together with a stiff left arm will help you

maintain control of the saw if kickback occurs.

• Make sure that the area in which you are cut-

ting is free from obstructions. Do not let the

nose of the guide bar contact a log, branch,

fence, or any other obstruction that could be

hit while you are operating the saw.

• Always cut with the unit running at full speed.

Fully squeeze the throttle trigger and maintain

a steady cutting speed.

• Use replacement parts such as low kickback

chain, chain brakes, SAFE-T-TIP
