NOTE
○ Minimize warm-up cutting with the band saw blade.
Warm-up cutting shortens the lifespan of the band
saw blade.
○ 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.
CAUTION: on lithium-ion battery
To extend the lifetime, the lithium-ion battery
equips with the protection function to stop the
output. Therefore, if the tool is overloaded, the
motor may stop. However, this is not the trouble
but the result of protection function. In this case,
release the switch of tool and eliminate the
causes of overloading.
CAUTION
● When switching on the tool, make sure the band
saw blade is not in contact with the workpiece.
Failure to do so may result in injury.
● For cutting effi ciency, switch the band saw blade
speed according to operating conditions and
workpiece to be cut.
● Do not apply any unnecessary pressure when
operating the tool. Doing so may damage the
band saw blade.
● After use, be sure not to place the tool near chips
before it comes to a full stop as the tool may suck
in those particles.

CUTTING OPERATION

WARNING
● Be absolutely sure to keep the switch turned off
and the battery removed to prevent any accident.
● During operation, do not place your face or
hands near the application tool of the unit.
○ Select a band saw blade (the band saw blade's teeth/

suitable for properties and thickness of the workpiece
to be cut.
