Overheat warning lamp
Off
Flashing: Overheat
(normal
Indicates operation has
operation)
been halted due to
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
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 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.
[Battery Pack]
For Appropriate Use of
Battery Pack [Fig. 8]
• For optimum battery life, store the Li-ion
battery pack following use without
charging it.
• When operating the battery pack, make
sure the work place is well ventilated.
For safe use
• If the battery pack is not connected firmly
when the switch is switched on, the
overheat warning lamp and the battery
low warning lamp will flash to indicate that
safe operation is not possible, and the
main unit will not rotate normally. Connect
the battery pack into the unit of the tool
until the red or yellow label disappears.
• Only use rechargeable battery packs for
Panasonic rechargeable tools. Do not use
modified battery packs (including battery
packs which have been disassembled
and parts replaced).
• Do not use deteriorated battery packs.
There is a risk of the generation of heat,
ignition and explosion.
• If a battery pack leaks fluid, cease use,
keep away from open flames, and return
it to the store immediately.
• Attach the battery pack by sliding until the
yellow and red labels are no longer
visible, and check that it does not fall out
of place.
- Failure to do so may result in scalding.
• The usage temperature range for lithium
ion battery packs is 0 to 40 degrees.
- Use of battery packs cooled to below
zero, such as in colder northern areas,
may result in abnormal operation of the
device. In such cases, leave the battery
pack in a location of 10 degrees or more
for one hour or more before use, and
only use the device after the battery
pack has warmed up.

Charging
CAUTION:
1) If the temperature of the battery pack
falls approximately below −10°C
(14°F), charging will automatically stop
to prevent degradation of the battery.
