WORKING TECHNIQUES
Never cut straight through a tree or branch that is in 
tension! 
If you must cut across tree/limb, make two to three cuts, one 
inch apart, one to two inches deep.
Continue to cut deeper until tree/limb bends and tension is 
released.
Cut tree/limb from outside the bend, after tension has been 
released.
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.
Limbing
Make sure that you can stand and move about safely. Work on 
the left side of the trunk. Work as close as 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.
Cutting the trunk into logs
See instructions under the heading Basic cutting 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.
!
WARNING! A majority of kickback accidents 
occur during limbing. Do not use the 
kickback zone of the guide bar. Be extremely 
cautious and avoid contacting the log, other 
limbs or objects with the nose of the guide 
bar. Be extremely cautious of limbs under 
tension. They can spring back toward you 
and cause loss of control resulting in injury.
