Check regularly:

•

Whether there are burrs on the edges of the bar. Remove 
these with a file if necessary.

•

Whether the groove in the bar has become badly worn. 
Replace the bar if necessary.

•

Whether the tip of the bar is uneven or badly worn. If a 
hollow forms on the underside of the bar tip this is due to 
running with a slack chain.

•

To prolong the life of the bar you should turn it over daily.

The word kickback is used to describe the sudden reaction 
that causes the chain saw and bar to jump off an object when 
the upper quadrant of the tip of the bar, known as the kickback 
zone, touches an object.

Kickback always occurs in the cutting plane of the bar. 
Normally the chain saw and bar are thrown backwards and 
upwards towards the user. However, the chain saw may move 
in a different direction depending on the way it was being used 
when the kickback zone of the bar touched the object.

Kickback only occurs if the kickback zone of the bar touches 
an object.

If you understand what kickback is and how it happens 
then you can reduce or eliminate the element of surprise. 
By being prepared you reduce the risk. Kickback is usually 
quite mild, but it can sometimes be very sudden and 
violent.

2

Always hold the chain saw firmly with your right hand on 
the rear handle and your left hand on the front handle. 
Wrap your fingers and thumbs around the handles. You 
should use this grip whether you are right-handed or left-
handed. This grip minimises the effect of kickback and lets 
you keep the chain saw under control.
