(1) Battery low warning lamp
Off (normal
Flashing (No charge)
operation)
Battery protection
feature active.
Excessive (complete) discharging of Li-
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 ac-
tivates immediately before the bat-
tery loses its charge, causing the
battery low warning lamp to flash.
• If you notice the battery low warn-
ing lamp flashing, charge the bat-
tery 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 in-
dicates that there is too little bat-
tery 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 trig-
gered, and the battery low warn-
ing lamp may flash. The lamp will
stop flashing once you address the
cause of the motor's locking up
and cycle the trigger.
(2) Overheat warning lamp
Off (normal Flashing: Overheat
operation)
Indicates operation has
been halted due to motor
or battery overheating.
To protect the motor or battery, be
sure to note the following when car-
rying out this operation.
• If the motor or battery becomes hot,
the protection function will be acti-
vated and the motor or battery will
stop operating. The overheat warn-
ing lamp on the control panel illumi-
nates or flashes when this feature is
active.
• If the overheating protection fea-
ture activates, allow the tool to cool
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 over-
heating protection feature may ac-
tivate frequently.
• If the tool is used in cold-temper-
ature conditions (such as during
winter) or if it is frequently stopped
during use, the overheating protec-
tion 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.
NOTE:
• In summer or in other situations
where the temperature is high, the
overheating protection feature may
activate and prevent continual use.
