NOTE
The recharging time may vary according to the ambient temperature and power source voltage.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger firmly 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 first 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 (offfor
0.3 seconds). In such a case, first let the battery cool,
then start charging.
○When the charge indicator lamp flickers (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.

the switch is “ON”.
The LED light will automatically power offabout
15 seconds after the switch is released.
*6 Adjusting operating speed
CAUTION
Use the band saw blade circumferential speed setting
dial to select a speed that is suitable for the workpiece.
Cutting with a band saw blade or band saw blade
circumferential speed that is unsuitable for the workpiece
will decrease cutting precision, and may also result in
damage to the band saw blade.
○In Standard Mode, the circumferential speed of the
band saw blade can be freely set from 1 to 5 on the
dial.
On the dial, 1 is the lowest speed and 5 is the highest
speed.
In Standard Mode, the circumferential speed that is
set with the dial is maintained even when the load
changes.
○In AUTO Mode (“A” on the dial), noise can be reduced
and the duration of operation can be extended by
lowering the circumferential speed when there is no
load.
In AUTO Mode, if a load is applied during operation,
the circumferential speed is automatically increased.
(Equivalent of 5 on the dial)
Additionally, if the load becomes lighter after
cutting is completed, the circumferential speed
is automatically decreased, reducing power
consumption when there is no load.
*1 How to use the Hook
The hook can be used to hang up the unit
temporarilyduring operations.
CAUTION
The hook should never be used to hang the unit on your
person.
When using the hook, check to make sure that the main
unit will not slip and fall, or become unstable by the wind,
etc.
Never hang the unit from your belt or trousers as this
could cause accidents.
*2 Adjusting the positions of bearing holders
WARNING
Securely tighten the M8 bolt.
Insufficient tightening will not only negatively affect
cutting precision, but may also damage the band saw
blade leading to personal injury.
NOTE
Cutting with excessively large spacing between bearing
holders may shorten the life of the band saw blade or
adversely affect cutting precision.
*3 Guide plate protrusion adjustment*
In the ordinary operation, protrude the guide plate to the
A side fully.
When the guide plate strikes against the obstacles like
a wall or the like at the finishing of a cut, slide it at the
appropriate position.
*4 Switch operation
With the lever switch in the “ON” position, pulling the
switch while pressing the switch lock will rotate the band
saw and light up the LED light.
When you release the switch, the revolution of the band
saw blade will stop and the LED light will automatically
be extinguished in approximately 15 seconds.

*7 Replacing the band saw blade
WARNING
○When replacing the band saw blade, be sure to switch
offthe power and remove the battery from the cordless
tool.
Use caution when changing or inspecting the band saw
blade as it may sometimes spring out.
CAUTION
○Wear gloves when changing the band saw blade.
○The band saw blade is hot immediately after operation.
Remove it only after it has cooled.
○Verify that there are no nicks, cracks, or other
abnormalities on the band saw blade before installing it.
○Wipe offany oil or grime adhering to the band saw blade
before installing it on the blade pulleys.
Additionally, wipe offany shavings or grime adhering to
the blade pulley rubbers.
If a band saw blade that has oil or grime adhering to it is
installed on the blade pulleys, the band saw blade may
slip or come loose.
○When installing the band saw blade, do not twist or bend
its joint.
Doing so may damage the band saw blade.
○If the band saw blade has a tendency to come loose,
loosen the tension lever and re-attach the band saw
blade.
○Minimize warm-up cutting with the band saw blade.
Warm-up cutting shortens the lifespan of the band
saw blade.
○Remove the band saw blade first from pulley guard
(C) ( in the figure), then from blade pulley (A) and
blade pulley (B), and lastly from the guide rollers
section ( in the figure) to remove it completely.
(Fig. 11-a)
○Being careful of the direction of revolution and the
facing of the band saw blade (Fig. 11-b), place the
band saw blade in Guide roller, installing the band
saw blade until it comes into contact with the Band
saw blade back ball bearing support.
○Make sure that the blade of the band saw blade is not
protruding from the edges of Blade pulley.
Rotate Blade pulley (A) in the revolving direction with
your hands and make sure the band saw blade does
not come loose. (Fig. 11-c)
*8 Cutting operation
○Select a band saw blade (the band saw blade’s
teeth/inch) and a band saw blade operating speed
that is suitable for properties and thickness of the
workpiece to be cut.
○As a basis for selecting a band saw blade with an
appropriate number of teeth/inch, select one that fits
2 or more teeth within the thickness of the workpiece.
○When switching the power on, verify that the band
saw blade is not in contact with the workpiece to be
cut or any surrounding objects.
○If the band saw blade locks up while cutting, promptly
switch offthe power and stop it from running.
Failure to do so may result in damage to the band
saw blade.
○When using a new band saw blade, be sure to set
the band saw blade operating speed setting dial to
“1” and perform 1–2 warm-up cuts with a light cutting
load (while pulling slightly upward on the product) on
an object with an outer diameter of 20 mm or less
such as cylindrical rod (carbon steel).
Failure to perform warm-up cuts may result in nicks
on the blade edge and decreased cutting precision.
○Do not cut thermoplastic material. It can melt from
cutting friction heat which can result in the band saw
blade becoming wedged in the material, causing the
motor to lock up.
○Do not cut hard materials such as hardened steel.
○If there is a gap between the guide plate and the
workpiece, the piece may erratically shift position
and cause breakage to the band saw blade.
○Do not apply excessive loads to the band saw blade.
○When the workpiece is thin (2 mm thick or less), cut
with the piece slightly raised up.
○About continuous operation
This tool is equipped with a temperature protection
circuit for safeguarding the motor as well as the
electronic motor drive control components.
If the tool is operated continuously, the temperature
of the unit may rise and activate the temperature
protection circuit, automatically stopping operation.
If this happens, allow the machine to sufficiently cool.
Once the temperature has decreased, the tool is
ready to be used again.
In the event the storage battery is changed during
continuous operation, allow the cordless tool to rest
for about 15 minutes before resuming use.
If operation is resumed soon after the battery is
changed, the temperatures of the motor, switch, etc.
will become high and may result in malfunction or
damage.
○When holding the unit, make sure the band saw
blade is perpendicular to the workpiece.
Additionally, there is no need to push the unit with
any excessive force.
Be aware that applying any excessive prying or
pressing force to the tool may result in the unit’s
malfunction or damage.
