WORKING TECHNIQUES

General advice:
Position yourself so that you will be clear of the tree or 
branch when the tension is released.
Make one or more cuts at or near the point of maximum 
tension. Make as many cuts of sufficient depth as 
necessary to reduce the tension and make the tree or 
branch break at the point of maximum tension.
Never cut straight through a tree or branch that is in 
tension! 
How to avoid kickback
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.
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.

technique.
!
WARNING! Kickback can happen very 
suddenly and violently; kicking the chain 
saw, 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 
it by taking care and using the right 
working technique.
