Setup
1. Charging the Battery
Before first use, fully charge the battery. Connect the charger to a standard power outlet. Slide the battery pack onto the charger until it clicks into place. The charging indicator light will show the charging status. A full charge typically takes approximately 3-5 hours. Always use the BLACK+DECKER charger supplied with your tool.
2. Installing/Removing the Battery
To install the battery, align the battery pack with the receptacle on the tool and slide it in until it locks securely. To remove, press the battery release button (usually located on the front or sides of the battery) and slide the battery pack out.
3. Installing/Removing Drill Bits or Screwdriver Bits
- Ensure the tool is switched off and the battery is removed for safety.
- Rotate the chuck collar counter-clockwise to open the chuck jaws.
- Insert the desired drill bit or screwdriver bit into the chuck, ensuring it is centered.
- Rotate the chuck collar clockwise to tighten the jaws firmly around the bit. Hand-tighten only; do not use a wrench.
- To remove, rotate the chuck collar counter-clockwise and pull the bit out.
Operating Instructions
1. Powering On/Off and Variable Speed Control
The tool is activated by pressing the trigger switch. The speed is variable; the further the trigger is pressed, the faster the tool operates. Release the trigger to turn the tool off. The integrated LED light illuminates the work area when the trigger is pressed.
2. Forward/Reverse Selector
A slide switch located above the trigger controls the direction of rotation. Push the switch to the left for forward rotation (for drilling and screwing in). Push it to the right for reverse rotation (for unscrewing). Position the switch in the center to lock the trigger and prevent accidental starting.
3. Torque Adjustment
The torque collar, located behind the chuck, allows you to select from 10 torque settings plus a drilling mode. Rotate the collar to align the desired setting with the indicator arrow. Lower numbers are for driving small screws or working with soft materials, while higher numbers and the drill symbol are for drilling or driving large screws into harder materials.
- Screwing: Select a lower torque setting to prevent over-tightening or damaging the screw head/material. Increase the setting if the screw is not driven deep enough.
- Drilling: Always select the drill symbol setting for drilling operations to achieve maximum power.
