(2) Overheat warning lamp
Off Illuminated:
(normal Overheat
operation) (motor)
Indicates operation has
been halted due to motor
or battery overheating.
To protect the motor or battery, be sure to
note the following when carrying out this
operation.
If the motor or battery becomes hot, the
●
protection function will be activated and
the motor or battery will stop operating.
The overheat warning lamp on the
control panel illuminates or flashes when
this feature is active.
If the overheating protection feature

thoroughly (at least 30 minutes). The
tool is ready for use when the overheat
warning lamp goes out.
Avoid using the tool in a way that causes
●
the overheating protection feature to
activate repeatedly.
If the tool is operated continuously under
●
high-load conditions or if it is used in hot-
temperature conditions (such as during
summer), the overheating protection
feature may activate frequently.
If the tool is used in cold-temperature
●
conditions (such as during winter) or if
it is frequently stopped during use, the
overheating protection feature may not
activate.
The ambient temperature range is
●
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C (32°F),
the tool may fail to function properly.
When charging a cool battery pack
●
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place and
wait for more than one hour to warm up
the battery to the level of the ambient
temperature.

(3) Battery low warning lamp
Flashing:
Overheat
(battery)
Excessive (complete) discharging of
lithium ion batteries shortens their service
life dramatically. The driver includes a
battery protection feature designed to
prevent excessive discharging of the
battery pack.
The battery protection feature activates
●
immediately before the battery loses its
charge, causing the battery low warning
lamp to flash.
If you notice the battery low warning
●
lamp flashing, charge the battery pack
immediately.
If it is started with too little battery power
●
remaining, the tool may stop operating
without the battery low warning lamp
flashing first. This indicates that there is
too little battery power remaining to use
the tool, and the battery pack should be
charged before further use.
If the tool is subject to a sudden load
●
during use that causes the motor to
lock up, the overdischarge prevention
sensor may be triggered, and the battery
low warning lamp may flash. The lamp
will stop flashing once you address the
cause of the motor's locking up and cycle
the trigger.
