guard against kickback.

16. 

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 injury to user.

the following precautions should 

be followed to minimize kickback:

Grip Saw firmly.

 

a. 

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.
Do not over reach.

b. 

Keep proper footing and balance at 

c. 

all times.
Don’t let the nose of the guide bar 

d. 

contact a log, branch, ground or 

other obstruction.
Don’t cut above shoulder height.

e. 

Use devices such as low kickback 

f. 

chain, guide bar nose guards and 

special guide bars that reduce the 

risks associated with kickback.
