• If the overheating protection feature
activates, allow the tool to cool thor-
oughly (at least 30 minutes). The
tool is ready for use when the over-
heat 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 un-
der high-load conditions or if it is used
in hot-temperature conditions (such as
during summer), the over-heating pro-
tection feature may activate frequently.
• If the tool is used in cold-tempera-
ture conditions (such as during win-
ter) or if it is frequently stopped dur-
ing use, the overheating protection
feature may not activate.

Excessive (complete) discharging of
lithium ion batteries shortens their
service life dramatically. The driver in-
cludes a battery protection feature
designed to prevent excessive dis-
charging of the battery pack.
• The battery protection feature ac-
tivates immediately before the bat-
tery loses its charge, causing the
battery low warning lamp to flash.
• If you notice the battery low warning
lamp flashing, charge the battery
pack immediately.

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.
• 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.
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
