○ 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 3/4" 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 (0.08" 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.
For stable cut, always keep at least two teeth in the cut.

Select the proper cutting position for your workpiece by
referring to the fi gure.
1. Press the workpiece against the guide plate (Fig. 14)
Press the workpiece against the guide plate in a
position where there is no contact with the band saw
blade.
2. Press the switch and cut (Fig. 14)
When the revolutions are stable, avoid any sudden
impact to the band saw and gently bring the band saw
to the workpiece to cut.
When completing a cut, hold the tool fi rmly, so it will
not fall against the workpiece.
