Always monitor the workplace and surrounding area,
ensure there are no objects which could cause injuries,
accidents or failure, and if any are present, remove them
in advance.
In particular, when establishing a foothold for working,
ensure there is no instability or any object which could be
tripped over.
Ensuring the unit is switched off
If the storage battery is inserted while the switch is
unknowingly engaged, the unit may unexpectedly
start, which may result in an accident.
Installing the battery (Fig. 5)
As shown in Fig. 5, push fi rmly until it clicks into place.
Engaging the switch
Ensuring the saw chain is not in contact with the timber,
engage the switch, and start cutting when the saw
chain speed has increased.
CAUTION
○ When switching the unit on, ensure the saw chain does
not contact with material or anything else.
○ During use, be careful to ensure the saw chain does
not contact with other material or object. In particular,
when you have fi nished cutting, be careful to ensure it
does not touch the ground.
NOTE
Refi ll the oil tank early to prevent the unit running out of
oil.
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. (Fig. 26)
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.
3. Log cutting
When cutting a log positioned as shown in Fig. 27, fi rst
cut in about one third of the way from below, then cut
down all the way from above. When cutting a log that
straddles a hollow as shown in Fig. 28, fi rst cut in about
two thirds of the way from above, then cut upward from
below.
CAUTION
○ Ensure the guide bar does not become bound in the log
by pressure.
○ When working on inclined ground, be sure to stand on
the uphill side of the log. If you stand on the downhill
side, the cut-off log may roll toward you.
4. Cutting a log laid fl at
Make sure the log is stable.
Push the spike against the log. Use the spike as a
fulcrum about which the handle can be lifted to facilitate
cutting. (Fig. 29)
5. Cutting a log supported at both ends
Start by sawing to a depth of approximately one third from
the top, then saw from underneath to complete the cut.
The guide bar may become stuck within the saw cut
if you attempt to cut all the way through from the top.
(Fig. 30)
Precaution for cutting work
For large-scale operation or non-stop work
This tool comes with an over-heat protection circuit
that protects the electronic parts that control the
rechargeable battery. During sustained use or
during operations under high loads generated by
pressure against the tool, tool temperature will rise
and eventually trigger the over-heat protection circuit,
which will shut down the tool.
If this happens, let the tool cool for a length of time.
When the temperature drops, it will again become
possible to use the tool. When the rechargeable battery
has to be exchanged during continuous operation, let
the tool rest for about 15 minutes.
Gripping/pushing force of chain saw
Always grip the chain saw securely.
In addition, do not force the chain saw more than
necessary. When cutting, additional force exerted on
the chain saw will not accelerate the cutting speed.
This will strain the motor, impair the performance, and
damage or cause malfunction of the motor or guide bar.
Use the unit in the range where the saw chain is at a
reasonable speed.
In particular, when the saw chain stops (becomes
jammed) due to the excessive force, it may cause an
injury or failure of the unit.
Chain catcher
○ The chain catcher is located on the power head just
below the chain to further prevent the possibility of a
broken chain striking the chain saw user.
○ When the saw chain is cut, replace it with a new one
referring to "Installing (replacing) saw chain".
