Pinch Kickback

1

1. Pinching the saw chain along the top of the guide

bar may push the saw back at you.

 

2. If the bar is pushed back far enough so that the

 

kickback zone hits an object, a rotational kickback

 

may occur.

Direction of Kickback

 

A kickback always travels in the plane of the bar.

 

Depending on how you hold the electric chain saw,

 

a kickback may come up and back at you or move in

 

any angle you happen to hold the electrc chain saw in.

 

For example, if you experience a kickback during felling,

 

the electric chain saw will move in the horizontal plane

 

and can swing around and hit your leg.

 

IMPORTANT!

 

Kickback can only occur if the kickback danger

 

zone of the bar touches an object.

 

A kickback can be lightning fast.

 

Although most kickbacks are small, a

 

kickback can sometimes be very violent.

 

Always be sure of your footing and hold the chain

 

saw firmly with both hands while the motor is

 

running.
