Battery Pack Life; Battery Recycling - Panasonic EY7442 Operating Instructions Manual

• 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.

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