High winds may force the tree to fall in an
unexpected direction causing property
damage or personal injury.
CAUTION
Never use a chain saw to pry or for any
purpose for which it is not intended.
WARNING
● Avoid stumbling on obstacles such as
stumps, roots, rocks, branches and fallen
trees. Watch out for holes and ditches. Be
extremely cautious when working on slopes
or uneven ground.
Shut off the saw when moving from one work
place to another.
Always cut at wide open throttle. A slow
moving chain can easily catch and force the
saw to jerk.
● Never use the saw with only one hand.
You cannot control the saw properly and
you may lose control and injure yourself
severely.
Keep the saw body close to your body to
improve control and reduce strain.
When cutting with the bottom part of the
chain the reactive force will pull the saw
away from you towards the wood you are
cutting.
The saw will control the feeding speed and
sawdust will be directed towards you. (Fig.

● When cutting with the upper part of the chain
the reactive force will push the saw towards
you and away from the wood you are cutting.

● There is a risk of kickback if the saw is
pushed far enough so that you begin to cut
with the nose of the bar.
The safest cutting method is to cut with the
bottom part of the chain. Sawing with the
upper part makes it much more diffi cult to
control the saw and increases the risk of
kickback.
● In case the chain locked, immediately release
the throttle lever.
If the throttle lever keeps rotating at high
speed with the chain locked, the clutch will
overheat causing trouble.
NOTE
Always keep the spiked bumper face to a tree,
because the chain may suddenly be drawn into a
tree.
FELLING
Felling is more than cutting down a tree. You must
also bring it down as near to an intended place as
possible without damaging the tree or anything else.
Before felling a tree, carefully consider all conditions
which may eff ect the intended direction, such as:
Angle of the tree. Shape of the crown. Snow load on
the crown.
Wind conditions. Obstacles within tree range (e.g.,
other trees, power lines, roads, buildings, etc.).
WARNING
● Always observe the general conditions of
the tree. Look for decay and rot in the trunk
which will make it more likely to snap and
start to fall before you expect it.
● Look for dry branches, which may break and
hit you when you are working.
Always keep animals and people at least
twice the tree length away while felling. Clear
away shrubs and branches from around the
tree.
Prepare a path of retreat away from the
felling direction.
BASIC RULES FOR FELLING TREES
Normally the felling consists of two main cutting
operations, notching and making the felling cut. Start
