1. General cutting procedures
(1) Switch ON the power while keeping the saw
slightly away from the wood to be cut. Start
sawing only after the unit has reached full
speed.
(2) When sawing a slender piece of wood, press
the base section of the guide bar against the
wood and saw downward as shown in Fig. 21.
(3) When sawing a thick piece of wood, press the
spike on the front section of the unit against the
wood and cut it with a lever action while using
the spike as a fulcrum as shown in Fig. 22.

(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 front 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 rear
handle to the right. (Fig. 23)

(5) When cutting into wood from the bottom, touch
the upper part of the guide bar to the wood
lightly. (Fig. 24)

(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 thorough 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.
2. 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 then cut off the branch from above.
Finally, cut off the remaining portion of the
branch even with the trunk of the tree. (Fig. 25)
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.
