• 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.
(O) Overheat warning lamp (battery)
Off
(normal
operation)
Flashing: Overheat
Indicates operation
has 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. 12]
• 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.
