•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.
