* Circumferential speeds may vary from those stated above depending on operating conditions
*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 suffi ciently 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.
BAND SAW BLADE SELECTION
Select a band saw blade based on the thickness of the
workpiece being cut, using the chart below as a guideline.

MAINTENANCE AND INSPECTION
WARNING
○ To prevent any accidents, be sure to switch off the 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. 9)
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 effi ciency.
Do not delay in replacing the band saw blade.
2. Blade pulley rubbers inspection (Fig. 12)
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.
