- To Remove: Press the battery release button and slide the battery pack out of the handle.
5.3. Installing/Removing Drill Bits or Screwdriver Bits
- Ensure the drill is switched off and the forward/reverse selector is in the neutral (locked) position.
- Rotate the keyless chuck counter-clockwise to open the jaws.
- Insert the desired drill bit or screwdriver bit into the chuck. Ensure it is inserted as far as possible.
- Rotate the keyless chuck clockwise to tighten the jaws firmly around the bit.
- To remove, rotate the chuck counter-clockwise and pull the bit out.
6. Operating Instructions
6.1. Selecting Operating Mode (3-in-1 System)
The drill driver features three operating modes: Screw Driving, Drilling, and Impact Drilling. Rotate the mode selector ring to choose the appropriate mode for your task.
Figure 3: Mode selection for Screw Driving, Drilling, and Impact Drilling.
- Screw Driving Mode: For driving and removing screws.
- Drilling Mode: For drilling holes in wood, metal, and plastic.
- Impact Drilling Mode: For drilling into masonry and harder materials like brick and cement.
6.2. Adjusting Torque Settings
The torque adjustment ring allows you to select from 25+3 torque settings, providing precise control for various materials and screw sizes. Lower settings are for smaller screws or softer materials, while higher settings are for larger screws or harder materials.
Figure 4: Torque adjustment for various materials and applications.
The maximum torque available is 42 Newton-meters, suitable for a wide range of tasks.
Figure 5: The drill's internal components enable a maximum torque of 42 N.m.
6.3. Selecting Speed Range
Use the speed selector switch (typically located on top of the drill) to choose between two speed ranges:
- Low Speed (0-550 RPM): Recommended for screw driving and applications requiring higher torque.
- High Speed (0-1850 RPM): Recommended for drilling and applications requiring faster rotation.

6.4. Forward/Reverse Operation
The forward/reverse selector switch, located above the trigger, controls the direction of rotation. Push it to the left for forward rotation (driving screws, drilling) and to the right for reverse rotation (removing screws). Position it in the middle to lock the trigger and prevent accidental startup.
6.5. Using the LED Work Light
The integrated LED work light automatically illuminates when the trigger is pressed, providing visibility in dimly lit work areas.
