CORDLESS CHAIN SAW SAFETY
WARNINGS
1) General chain saw safety warnings
a) This chain saw is not intended for tree felling.
Use of the chain saw for operations diff erent than
intended could result in serious injury to the operator or
bystanders.
b) The operator must be trained in safe climbing
techniques and in the use of all recommended
additional safety equipment, such as harness,
loops, straps, rope and karabiners, and other
fall arrest systems for the operator and the saw.
Establishing a secure location in the tree at each
working position is essential to avoid a hazardous
situation.
c) Wear eye protection, ear protection and protective
equipment for head, forearms, hands, legs and feet
that is suitable for tree climbing. Adequate protective
equipment will reduce personal injury from fl ying debris
or accidental contact with the saw chain.
d) Cut wood only. Do not use chain saw for purposes
not intended. For example: do not use chain saw
for cutting metal, plastic, masonry or non-wood
building materials. Use of the chain saw for operations
diff erent than intended could result in a hazardous
situation.
e) Always hold the chain saw with your right hand
on the rear handle and your left hand on the front
handle. Holding the chain saw with a reversed hand
confi guration increases the risk of personal injury and
should never be done.
f) Hold the chain saw by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring. Saw chains contacting a "live" wire may make
exposed metal parts of the chain saw "live" and could
give the operator an electric shock.
g) Keep all parts of the body away from the saw chain
when the chain saw is operating. Before you start
the chain saw, make sure the saw chain is not
contacting anything. A moment of inattention while
operating chain saws may cause entanglement of your
clothing or body with the saw chain.
h) When cutting a limb that is under tension, be alert
for spring back. When the tension in the wood fi bres
is released, the spring loaded limb may strike the
operator and/or throw the chain saw out of control.
i) Use extreme caution when cutting thin branches.
The slender material may catch the saw chain and be
whipped toward you or pull you off balance.
j) Follow all instructions when clearing jammed
material, storing or servicing the chain saw.
Make sure the switch is off and the battery pack
is removed. Unexpected actuation of the chain saw
while clearing jammed material or servicing may result
serious personal injury.
k) Carry the chain saw by the front handle with the
chain saw switched off and away from your body.
When transporting or storing the chain saw, always
fi t the guide bar cover. Proper handling of the chain
saw will reduce the likelihood of accidental contact with
the moving saw chain.
l) Follow instructions for lubricating, chain tensioning
and changing the bar and chain. Improperly
tensioned or lubricated chain may either break or
increase the chance for kickback.
2) Causes and operator prevention of kickback:
Kickback may occur when the nose or tip of the guide
bar touches an object, or when the wood closes in and
pinches the saw chain in the cut. (Fig. 2)
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
Pinching the saw chain along the top of the guide
bar may push the guide bar rapidly back towards the
operator.
Either of these reactions may cause you to lose control
of the saw which could result in serious personal
injury. Do not rely exclusively upon the safety devices
built into your saw. As a chain saw user, you should
take several steps to keep your cutting jobs free from
accident or injury.
Kickback is the result of machine misuse and/or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below:
a) Maintain a fi rm grip, with thumbs and fi ngers
encircling the chain saw handles, with both hands
on the saw and position your body and arm to allow
you to resist kickback forces. (Fig. 3) Kickback
forces can be controlled by the operator, if proper
precautions are taken. Do not let go of the chain saw.
b) Do not overreach. This helps prevent unintended tip
contact and enables better control of the chain saw in
unexpected situations.
c) Only use replacement guide bars and saw chains
specifi ed by the manufacturer. Incorrect replacement
guide bars and saw chains may cause chain breakage
and/or kickback.
d) Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.

NOTE
The recharging time may vary according to temperature
and power source voltage.
CAUTION
When the battery charger has been continuously used,
the battery charger will be heated, thus constituting
the cause of the failures. Once the charging has been
completed, give 15 minutes rest until the next charging.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after
use, and then keep it.
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period
is not activated, the electric discharge might be low when
using them the fi rst and second time. This is a temporary
phenomenon, and normal time required for recharging
will be restored by recharging the batteries 2–3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery. If
you continue to use the tool and exhaust the electric
current, the battery may be damaged and its life will
become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the battery
and recharge it after it has cooled for a while.
CAUTION
○ If the battery is charged while it is heated because it
has been left for a long time in a location subject to
direct sunlight or because the battery has just been
used, the charge indicator lamp of the charger lights
for 0.3 seconds, does not light for 0.3 seconds (off for
0.3 seconds). In such a case, fi rst let the battery cool,
then start charging.
○ When the charge indicator lamp fl ickers (at 0.2-second
intervals), check for and take out any foreign objects in
the charger’s battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.

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.
16
English
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”.
SHARPENING OF THE CHAIN BLADE
WARNING
To prevent accidents, always turn off the switch and
remove the battery from the main body.
CAUTION
Always wear thick gloves when handling the saw chain.
NOTE
Sharpen the saw chain and adjust the depth gauge at
the central position on the guide bar, with the saw chain
attached to the main body.
When the sharpness of saw chains deteriorates, the motor
and each part of the body are burdened and the effi ciency
declines.
For optimal performance of the unit, frequent maintenance
is necessary to keep the saw chain sharp.
1. Blade sharpening
Use a 4 mm diameter round fi le.
The round fi le should be held against the chain blade
so that one-fi fth of its diameter extends above the top
of the blade, as shown in Fig. 31.
Sharpen the blades by keeping the round fi le at a 30°
angle in relation to the guide bar, as shown in Fig. 32.
File the blades by gently pushing the round fi le in the
direction of the grip.
Make sure the round fi le does not touch the saw chain
when drawing back the fi le.
Ensure that all saw blades are fi led at the same angle,
or the cutting effi ciency of the tool will be impaired.
Appropriate angles for sharpening the blades correctly
are shown in Fig. 33. (Round fi le is sold separately.)
2. Adjustment of depth gauge
WARNING
○ Do not sand the top part of the bumper tie strap and
bumper drive link, nor cause the shape of said parts to
deform.
○ Adjustment of depth gauges must be in line with the
predetermined dimensions and shapes, otherwise the
risk of kickback may increase, causing an injury.
Bumper tie strap Bumper drive link
Depth gauges shall be all lined up in the same manner
because they are used to adjust depth at the position
where the cutter inlays into the wood.
When sharpening the saw chain, be sure to check the
depth gauge every two or three times. (Fig. 34)
17
English
Place a depth gauge jointer on the saw chain, leave the
gauge visible at the groove, and use a fl at fi le to bevel
the portion out of the depth gauge jointer. (Fig. 35)
(Depth gauge jointer and fl at fi le are sold separately.)
After fi ling away the depth gauge, round off the front
side of the depth gauge as it was. (Fig. 36)
After sharpening the saw chain, place it into chain oil to
wash off the fi lings.
If fi lings are not cleaned off , the saw chain and guide
bar will quickly wear while in use.
The depth gauge jointer can also be used when
dressing with a round fi le. (Fig. 37)
MAINTENANCE AND INSPECTION
After operation, perform inspection and maintenance of
each part when storing the unit.
WARNING
During maintenance and inspection, always switch off
the unit and remove the battery from the main body.
CAUTION
Always wear thick gloves when handling the saw chain.
1. Inspection of saw chains
○ Occasionally inspect the saw chain. In the event of
any abnormality, replace it with a new one referring to
“Installing (replacing) saw chain” .
○ Inspect the chain tension and check If it is correctly
tightened.
○ Stop using the unit when the saw chain becomes blunt
and sharpen it referring to “Sharpening of the chain
blade”.
○ After use, carefully lubricate the saw chain and guide
bars with oil for rust-proofi ng.
NOTE
When cleaning the side cover, sprocket, chain oil
spout, and guide bar, see the procedure “Installing
(replacing) saw chain” and remove the saw chain.
2. Cleaning the side cover and sprocket (Fig. 38)

3. Cleaning the chain oil spout (Fig. 39)
Before cleaning the chain oil spout, remove the side
cover and guide bar.
4. Cleaning the guide bar (Fig. 40)
When sawdust and similar become clogged in the
groove of the guide bar or oil spout, the oil may not fl ow,
which may result in the unit failing.
Remove the guide bar and clean any sawdust clogged
in the groove after use and when replacing the saw
chain. (Refer to “Installing (replacing) saw chain.”)
5. Cleaning the chain brake (Fig. 41)
Use a brush to remove any swarf from the gap to the
saw body.
6. Inspecting the chain catcher (Fig. 42)
The chain catcher is designed to protect the operator
from being struck by the saw chain if the chain comes
loose or is severed.
The chain catcher is integrated into the side cover.
Check to confi rm that the chain catcher is not damaged.
7. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
8. Maintenance of the motor
The motor unit winding is the very “heart” of the power
tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
9. Cleaning the battery installation compartment
and the battery (Fig. 43)
WARNING
Wear protective glasses and a dust mask when
cleaning with an air blow gun.
Failure to do so may result in inhalation or exposure of
the eyes to debris or dust.
Use a brush or air blow gun to remove any swarf or dust
and keep the saw clean.
NOTE
○ Allowing swarf and dust to build up during use may
cause the battery to fall off or other accidents.
Allowing swarf and dust to build up can also result in
malfunctions, including faulty contact between the
battery and the terminals.
○ After cleaning, check to confi rm that the battery can be
easily detached and reattached to the tool body.
10. Cleaning of the outside
When the chain saw is stained, wipe with a soft dry
cloth or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, for they melt
plastics.
11. Storage
○ Clean all parts thoroughly. Coat metal parts with a thin
layer of corrosion inhibitor.
○ Be sure to repair any damaged areas before storing.
○ When storing the unit, perform cleaning and
maintenance of each part and mount the chain case to
the guide bar.
○ Store the power tool and battery in a place in which
the temperature is less than 40°C and out of reach of
children.
NOTE
Storing Lithium-ion Batteries
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signifi cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries
dead and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
