*7 Replacing the band saw blade
WARNING
○ When replacing the band saw blade, be sure to switch
off the 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 off any oil or grime adhering to the band saw blade
before installing it on the blade pulleys.
Additionally, wipe off any 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 fi rst from pulley guard
(C) ( in the fi gure), then from blade pulley (A) and
blade pulley (B), and lastly from the guide rollers
section ( in the fi gure) to remove it completely.
(Fig. 12-a)
○ Being careful of the direction of revolution and the
facing of the band saw blade (Fig. 12-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. 12-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 fi ts
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 off the 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 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.
○ 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.
LED LIGHT WARNING SIGNALS
This product features functions that are designed to protect
the tool itself as well as the battery. When any of the
safeguard functions are triggered, any of the LED light will
blink as described in Table 4.
In this case, follow the instructions described under

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. 12)
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. 14)
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.
