4. When cutting wood horizontally, turn the unit body to
the right so that the guide bar is below and hold the
upper side of the side handle with your left hand. Hold
the guide bar horizontally and place the spike that is
on the front of the unit body on the lumbar.
Using the spike as a fulcrum, cut into the wood by
turning the handle to the right. (Fig. 16)

6. As well as carefully studying the handling instructions,
ensure practical instruction in the operation of the
chain saw prior to use, or at least practice working
with the chain saw by cutting lengths of round timber
on a sawing trestle.
7. When cutting logs or timbers which are not
supported, support them properly by immobilizing
them during cutting using a sawing trestle or other
proper method.
CAUTION
● When cutting wood from the bottom, there is a
danger that the unit body may be pushed back
toward the user if the chain strongly impacts with
the wood.
● Do not cut all the way through the wood by
starting from the bottom since there is the
danger of the guide bar fl ying up out of control
when the cut is fi nished.
● Always prevent the operating chain saw from
touching the ground or wire fences.
Branch cutting:
1. Cutting branches from a standing tree:
A thick branch should initially be cut off at a point
away from the trunk of the tree.
First cut in about one third of the way from below, and
Spiked bumper
then cut off the branch from above.
Finally, cut off the remaining portion of the branch
even with the trunk of the tree. (Fig. 18)
Guide bar
CAUTION
● Always be careful to avoid falling branches.
● Always be alert for chain saw recoil.
2. Cutting branches from fallen trees:
First cut off branches that do not touch the ground,
then cut off those which touch the ground. When
cutting thick branches that touch the ground, fi rst
cut in about half of the way from above, then cut the
branch off from below. (Fig. 19)
CAUTION
● When cutting off branches which touch the
ground, be careful that the guide bar does not
become bound by pressure.
● During the fi nal cutting stage, beware of the log
suddenly rolling.
Felling a tree:
When bucking and felling operations are being
performed by two or more persons at the same time,
the felling operations should be separated from the
bucking operation by a distance of at least twice the
height of the tree being felled. Trees should not be
felled in a manner that would endanger any person,
