KICKBACK PRECAUTIONS

See Figures 16 - 17.

Rotational kickback occurs when the moving chain 

contacts an object at the Kickback Danger Zone of 

the guide bar. The result is a lightning-fast reverse 
reaction, which kicks the guide bar up and back 
towards the operator. This reaction can cause loss 
of control, which can result in serious injury.

PREPARING FOR CUTTING
PROPER GRIP ON HANDLES

See Figure 18.

See 

General Safety Rules

 for appropriate safety 

equipment.

 

Wear non-slip gloves for maximum grip and 
protection.

 

Hold the saw firmly with both hands. Always 
keep your left hand on the front handle and your 
right hand on the rear handle so that your body 
is to the left of the chain line. 

WARNING:

Never use a left-handed (cross-handed) grip or 
any stance that would place your body or arm 
across the chain line.

 

Maintain a proper grip on the saw whenever the 
engine is running. The fingers should encircle 
the handle and the thumb is wrapped under the 
handlebar. This grip is least likely to be broken 
by a kickback or other sudden reaction of the 
saw. Any grip in which the thumb and fingers 
are on the same side of the handle is dangerous 
because a slight kick of the saw can cause loss 
of control.

operating a saw.
