SAFETY INSTRUCTIONS
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.
Freeing a tree that has fallen badly 
Freeing a ”trapped tree”
It is very dangerous to remove a trapped tree and there is high 
accident risk.
The safest method is to use a winch.
Tractor-mounted
Portable
Cutting trees and branches that are in tension
Preparations:
Work out which side is in tension and where the point of 
maximum tension is (i.e. where it would break if it was bent 
even more).
Decide which is the safest way to release the tension and 
whether you are able to do it safely. In complicated situations 
the only safe method is to put aside your chain saw and use 
a winch.
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! 
!
WARNING! Most kickback accidents happen 
during limbing! Pay close attention to the 
position of the kickback zone of the bar 
when you are limbing branches that are in 
tension!
