What is kickback?
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.
Keep the trunk between you and the chain saw as you move
along the trunk.
Cutting the trunk into logs
See instructions under the heading Basic cutting technique.
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.
