trigger pressure.
1/4" HEX CHUCK
NOTE: The chuck accepts 1/4" hex accessories and 1" bit tips only.
Place the forward/reverse button in the lock-off (center) position or remove battery pack before changing accessories.
To install an accessory, fully insert the accessory. The accessory is locked into place.
To remove an accessory, pull the chuck collar away from the front of the tool. Remove the accessory.

The direction-of-rotation selector located above the trigger switch changes the direction of bit rotation. Setting the
trigger switch in the OFF (center lock) position helps to reduce the possibility of accidental starting when not in use.

Pressing the trigger switch illuminates the LED worklight, located on the front of the Drill Driver. This feature
provides extra light for increased visibility.
OPERATION
CHARGING THE BATTERY
WARNING: The charger and battery pack are specifically designed to work together so do not attempt to use any
other devices. Never insert or allow metallic objects into your charger or battery pack connections because an
electrical failure and hazard will occur.
Your battery pack is UNCHARGED and you must charge once before use. The charger is designed to use standard
household 120volt 60Hz power.
1. Plug the charger adapter into a suitable power supply. The red light will illuminate. Insert the battery pack into
the charger base. The green light will come on and the red light will remain on.
2. A discharged battery at normal ambient temperature will take approximately 3-5 hours to reach full charge.
When charging is complete, the red light will turn off and only the green light will be illuminated.
BATTERY AND CHARGER SAFETY FEATURES
OVER CHARGING PROTECTION
The over charging protection will ensure that the battery is never overcharged. When the battery has reached its fully
charge capacity, the charger will automatic shut off, protecting the internal components of the battery from being
damaged.
OVER DISCHARGE PROTECTION
An internal component of the battery pack is an over discharge protector. This feature will stop the battery from
discharging beyond the recommended lowest safety voltage.
OVER HEAT PROTECTION
The battery has an internal thermister cut off censor which will cease the charging cycle if the battery becomes hot
during the charging process. This thermister censor will also stop the battery from operating should the battery
become too hot during the operation of the tool. This can happen when the tool is overloaded or being used for
extended periods of time.
