Charging Procedure
Recharge discharged batteries as soon as possible after use or battery life may be
greatly diminished. For longest battery life, do not discharge batteries fully.
It is recommended that the batteries be recharged after each use.
WARNING: Fire Hazard
. When unplug the output plug from the charging hole, be sure to
unplug the charger from the outlet first, then disconnect the charger output plug from the
charging hole.
Important Charging Notes
1) Your tool was sent from the factory in an uncharged condition. Before attempting to use it, it
must be charged.
2) CAUTION: To reduce the risk of damage to the batteries, NEVER charge them in an air
temperature below 40°F (4.5°C) or above 105°F (40.5°C). Also, NEVER charge them if the
battery temperature is below 40°F (4.5°C) or above 105°F (40.5°C). Longest life and best
performance occurs when batteries are charged with an air temperature of approximately 75°F
(24°C). NOTE: The tool will not charge if the tool temperature is below approximately 32°F
(0°C) or above 113°F (45°C).
3) While charging, the charger may hum and become warm to touch. This is a normal
phenomenon and does not indicate a problem.
