2. Installing and Removing the Battery
- To Install: Align the battery with the base of the drill and slide it in until it clicks securely into place.
- To Remove: Press the battery release button (usually located on the sides of the battery) and slide the battery out.
3. Installing and Removing Drill Bits
- To Install: Rotate the chuck counter-clockwise to open the jaws. Insert the drill bit into the chuck as far as it will go. Rotate the chuck clockwise to tighten the jaws securely around the bit.
- To Remove: Rotate the chuck counter-clockwise to loosen the jaws and pull the drill bit out.
4. Attaching the Auxiliary Handle
The auxiliary handle can be attached to either side of the drill for improved control, especially during hammer drilling or high-torque applications. Loosen the handle, slide it onto the drill head, and tighten it securely in the desired position.
Operating Instructions
1. Selecting Operating Mode
Your drill offers three modes: Drill, Screw-Driving, and Hammer-Drilling. Rotate the mode selector ring (located behind the chuck) to choose the appropriate mode for your task.
- Drill Mode: For drilling holes in wood, plastic, and metal.
- Screw-Driving Mode: For driving screws. Use with the torque adjustment ring.
- Hammer-Drilling Mode: For drilling into masonry and concrete.
2. Adjusting Torque
The torque adjustment ring allows you to set the clutch to prevent over-driving screws or damaging materials. There are 20 torque settings plus a drill mode setting. Start with a lower torque setting and increase as needed.

3. Selecting Speed Range
The 2-speed switch (located on top of the drill) allows you to select between two speed ranges:

Image: A user holding the drill, highlighting the 2-variable speed ranges. Speed 1 (0-400 RPM) is for high torque applications, and Speed 2 (0-1600 RPM) is for low torque applications.
- Speed 1 (0-400 RPM): Low speed, high torque. Ideal for driving screws and drilling large diameter holes.
- Speed 2 (0-1600 RPM): High speed, low torque. Ideal for drilling small diameter holes and faster drilling.
4. Direction of Rotation
The direction-of-rotation selector allows you to choose forward (clockwise) for drilling and driving, or reverse (counter-clockwise) for removing screws or freeing a jammed bit. The center position locks the trigger for safety.
5. Using the LED Worklight
The integrated LED worklight automatically illuminates when the trigger is pressed, providing visibility in dimly lit work areas.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your tool.
- Cleaning: Keep the ventilation slots clean to prevent overheating. Use a soft, damp cloth to clean the tool casing. Do not use harsh chemicals or abrasive cleaners.
- Chuck Maintenance: Periodically clean the chuck jaws to ensure proper gripping of bits.
- Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods.
