Setup
- Attaching the Auxiliary Handle: Loosen the auxiliary handle by twisting it counter-clockwise. Slide it over the chuck and position it to your preferred angle for optimal control. Tighten it securely by twisting clockwise.
- Installing the Depth Stop: Insert the depth stop rod into the hole on the auxiliary handle. Adjust its position to the desired drilling depth and secure it by tightening the screw on the auxiliary handle.
- Inserting a Drill Bit:
- Ensure the drill is unplugged from the power source.
- Twist the front part of the keyless chuck counter-clockwise to open the jaws.
- Insert the drill bit fully into the chuck.
- Twist the front part of the chuck clockwise to securely tighten the jaws around the drill bit. Ensure the bit is centered and firmly held.
Operating Instructions
1. Selecting Operating Mode
- Drilling Mode: For wood, metal, plastic, and soft materials. Set the function selector switch to the drill symbol.
- Impact Drilling Mode: For concrete, masonry, and hard materials. Set the function selector switch to the hammer symbol.

2. Adjusting Speed
The electronic speed control allows you to adjust the drilling speed according to the material and application. Use the speed control dial to pre-select the maximum speed, and the trigger switch to vary the speed during operation.
Figure 5: Speed Control Dial. This image shows the dial for adjusting the maximum rotational speed of the drill.

3. Forward/Reverse Rotation
Use the forward/reverse switch to select the direction of rotation. Forward rotation is for drilling and tightening screws, while reverse rotation is for loosening screws or extracting jammed drill bits.
4. Drilling Procedure
- Ensure the correct drill bit is installed and the auxiliary handle and depth stop are adjusted.
- Select the appropriate operating mode (drilling or impact drilling).
- Plug the drill into a suitable power outlet.
- Hold the drill firmly with both hands, ensuring a stable stance.
- Position the drill bit on the desired drilling point.
- Gently press the trigger switch to start drilling. Apply steady, even pressure.
- For continuous operation, press the lock-on button while the trigger is depressed. To release, press the trigger again.
- Once drilling is complete, release the trigger switch and wait for the drill bit to stop rotating before withdrawing it from the workpiece.
