Cautions for the Li-ion Battery
Pack
• If the temperature of the battery pack
falls approximately below −10°C
(14°F), charging will automatically
stop to prevent degradation of the
battery.
Common Cautions for the Li-
ion/Ni-MH/Ni-Cd Battery Pack
• 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.
• Cool down the charger when charg-
ing more than two battery packs con-
secutively.
• During charging, the charger may
become slightly warm. This is nor-
mal. Do NOT charge the battery for
a long period.

To prevent the risk of fire or damage to
the battery charger.
• Do not use power source from an
engine generator.
• Do not cover vent holes on the
charger and the battery pack.
