!
suddenly and violently; kicking the
chainsaw, bar and chain back at the user.
If this happens when the chain is moving
it can cause very serious, even fatal
injuries. It is vital you understand what
causes kickback and that you can avoid

working technique.
What is kickback?
The word kickback is used to describe the sudden
reaction that causes the chainsaw 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 chainsaw and bar are thrown backwards
and upwards towards the user. However, the chainsaw
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.

in injury.
Make sure that you can stand and move about safely.

possible to the chain saw for maximum control. If possible,
let the weight of the chain saw rest on the trunk.
Keep the trunk between you and the chain saw as you
move along the trunk.
