only the kickback zone of the bar is in contact with the
tree, which can lead to a kickback.
Cutting with the bottom edge of the bar, i.e. from the
top of the object downwards, is known as cutting with
a pulling chain. In this case the chain saw pulls itself
towards the tree and the front edge of the chain saw
body rests naturally on the trunk when cutting. Cutting
with a pulling chain gives the operator better control
over the chain saw and the position of the kickback
zone.

Follow the instructions on sharpening and maintaining
your bar and chain. When you replace the bar and
chain use only combinations that are recommended
by us. See instructions under the headings Cutting
equipment and Technical data.
Basic cutting technique
WARNING! Never use a chain saw by
!
holding it with one hand. A chain saw is
not safely controlled with one hand.
Always have a secure, firm grip around
the handles with both hands.
General
•
Always use full throttle when cutting!
•
Let go of the power trigger after every cut (running the
motor for too long at full power without any load, i.e.
without any resistance from the chain during cutting,
can lead to serious damage to the motor).
•
Cutting from above = Cutting with a pulling chain.
•
Cutting from below = Cutting with pushing chain.
Cutting with a pushing chain increases the risk of
kickback. See instructions under the heading How to
avoid kickback.
Terms
Cutting = General term for cutting through wood.
Cutting/bucking = General term for cutting through wood.
Limbing = Cutting branches off a felled tree.
WORKING TECHNIQUES
Splitting = When the object you are cutting breaks off
before the cut is complete.
There are a number of important factors you should
consider before making a cut:
1
Make sure the cutting equipment will not jam in the
cut.
2
Make sure the object you are cutting will not split.
3
Make sure the chain will not strike the ground or any
other object during or after cutting.
4
Is there a risk of kickback?
5
Do the conditions and surrounding terrain affect how
safely you can stand and move about?
6
When cutting on a slope, always stand on the uphill
side of the log. To maintain complete control of the
chain saw when cutting through the log, release the
cutting pressure near the end of the cut without
relaxing your grip on the chain saw handles. Do not let
the saw chain contact the ground. After completing
the cut, wait for the saw chain to stop before you move
the chain saw. Always stop the motor before moving
from tree to tree.
