Panasonic EY79A3 Instructions D'utilisation page 15

(2) Voltage Reduction Warning
Three lamps flashing.
If the tool is subject to a sudden
load during use that causes the
motor to lock up, the overdis-
charge prevention sensor may
be triggered, and the low battery warning
lamp may flash. The lamp will stop flash-
ing once you address the cause of the
motor's locking up and cycle the trigger.
[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 disas-
sembled 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.
[Battery Charger]
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.
2) 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.
3) Use the charger at temperatures
between 0°C and 40°C, and charge
the battery at a temperature similar to
that of the battery itself. (There should
be no more than a 15°C difference
between the temperatures of the
battery and the charging location.)
4) 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.
5) Cool down the charger when charging
more than two battery packs consecu-
tively.
6) Do not insert your fingers into contact
hole, when holding charger or any
other occasions.
7) Unplug the charger when not in use.
8) Store the charger between 0 and
40 degrees, and charge the battery
pack at a temperature close to the
storage temperature.
