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 firmly and pull out the battery.
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 pilot lamp of the charger lights up green or lights
for 1 second, does not light for 0.5 seconds (offfor
0.5 seconds). In such a case, first let the battery cool,
then start charging.

○When the pilot lamp flickers in red (at 0.2-seconds
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.
○Since the built-in micro computer takes about 3 seconds
to confirm that the battery being charged with chargers
are taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is
reinserted within 3 seconds, the battery may not be
properly charged.

○Using a soft cloth, wipe offany foreign matter that
has adhered to the lens of the LED light, being
careful not to scratch the lens.
Scratches on the LED light may reduce the
brightness of the light.
○When cleaning the lens of the LED light, do not wipe
with gasoline, paint thinner, etc.
Doing so will damage the lens.
*3 Remaining battery indicator
○To reduce battery consumption, the remaining
battery indicator lamp only lights up while the
remaining battery indicator switch is being pressed.
○Unless the power is switched on after installing the
battery to the unit, the remaining battery indicator
lamp will not light up when the remaining battery
indicator switch is pressed.
*4 Adjusting operating speed
This unit is equipped with an electronic control circuit
that allows the circumferential speed of the band saw
blade to be freely adjusted.
Prior to operation, use the band saw blade circumferential
speed setting dial to set a mode that suits the properties,
thickness and task conditions of the workpiece being
cut.
○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.

MAINTENANCE AND INSPECTION
WARNING
○To prevent any accidents, be sure to switch offthe power
and remove the battery from the cordless tool.
○Be sure to wear gloves when handling the band saw
blade.
1. Replacing the band saw blade (Fig. 10)
If the band saw blade becomes dull, it can result in
overburdening the motor and the various parts of the tool
as well as decrease efficiency.
Do not delay in replacing the band saw blade.
2. Blade pulley rubbers inspection (Fig. 13)
The blade pulley rubbers are installed on the outer
circumferences of the blade pulleys (2 places). (Fitted
type)
When replacing the band saw blade, inspect the blade
pulley rubbers for sagging or damage.
If there is sagging or damage, request a replacement
from HiKOKI Authorized Service Center, as it may result
in the band saw blade running unstable or coming loose.
NOTE
Periodically remove any shavings, etc. that has adhered
to the blade pulley rubbers.
Failure to do so may result in slippage of the band saw
blade and/or injury.
3. Inspection of band saw blade back ball bearing
supports (Fig. 14)
Periodically inspect the band saw blade back ball
bearing supports inside the bearing holders for wear.
If the band saw blade back ball bearing supports are
worn, there will be excessive force on the band saw
blade that could result in damage to the band saw blade.
If the band saw blade back ball bearing supports are
worn, arrange for replacements from HiKOKI Authorized
Service Center.
4. Inspection of band saw blade ball bearing supports
and adjustment of gaps (Fig. 15)
After continued use of the unit, the gaps between the
band saw blade ball bearing supports may become
wider.
If the gaps become wider, the band saw blade may tilt,
resulting in reduced cutting precision.
Periodically inspect whether the gaps between the
band saw blade ball bearing supports are appropriate
(bearings are lightly touching the band saw blade), and
make any adjustments if necessary.
Additionally, if the band saw blade ball bearing supports
are damaged, arrange for replacements from HiKOKI
Authorized Service Center.
*5 Replacing 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.
*6 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.
○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.
○About holding the unit and applying force
Hold the tool securely with both hands.
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.
