Rules for Safe Operation

Kickback Safety Precautions for Chainsaw Users

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. 

The optional Kick Guard

TM

 device is 

not installed on the guide bar when 

you purchase your chainsaw. The 

optional Kick Guard

 

can be used in 

a majority of cutting operations, and 

is especially recommended for 

beginners, homeowners, or 

chainsaw novices. Most cutting 

operations can be accomplished 

with the optional Kick Guard in 

place.

Do not rely exclusively upon the safety devices built into your saw. As a 

chainsaw user, you should take several steps to keep your 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.
