Cautions for the Li-ion Battery
Pack
• If the temperature of the battery pack falls
approximately below −10°C (14°F), charg-
ing will automatically stop to prevent degra-
dation of the battery.
Common Cautions for the Li-
ion/Ni-MH/Ni-Cd Battery Pack
• The ambient temperature range is between
0°C (3°F) and 40°C (104°F).
If the battery pack is used when the bat-
tery temperature is below 0°C (3°F),
the tool may fail to function properly.
• When charging a cool battery pack (below
0°C (3°F)) in a warm place, leave the
battery pack at the place and wait for
more than one hour to warm up the bat-
tery to the level of the ambient tempera-
ture.
• Cool down the charger when charging more
than two battery packs consecutively.
• Do not insert your fingers into contact
hole, when holding charger or any other
occasions.
CAUTION:
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.
• Unplug the charger when not in use.
