6. Operating Instructions
6.1 Power On/Off
To start the drill, press the stepless speed regulation button (trigger). To stop, release the trigger. The speed is proportional to how far the trigger is pressed.
6.2 Speed Adjustment (Gear Selection)
The drill features a 2-speed gearbox for optimal performance in various applications:
- 1st Gear (Low Speed, 0-350 RPM): Ideal for tightening screws and applications requiring higher torque.
- 2nd Gear (High Speed, 0-1400 RPM): Suitable for drilling holes and tasks requiring faster rotation.
Adjust the gear using the switch located on top of the drill body as required for your task.
6.3 Torque Setting
The drill offers 25+1 torque settings (up to 45 N.m) to prevent over-tightening screws and damaging materials. Rotate the torque collar to select the desired setting based on the material and fastener size.
- Settings 1-5: For PVC and delicate materials.
- Settings 7-11: For wood.
- Settings 13-17: For brick.
- Settings 19-25: For ceramic tile and harder materials.
- Drill Mode (+1 setting): For drilling applications where maximum torque is desired.
6.4 Forward/Reverse Function
The forward/reverse switch allows you to change the rotation direction of the chuck. This is essential for driving screws (forward) and removing them (reverse).
- Forward Button (Left side): For screwing.
- Reverse Button (Right side): For removing screws.
- Middle Position: Locks the machine, preventing accidental activation.
6.5 LED Work Light
The integral LED work light automatically illuminates when the trigger is pressed, providing visibility in dark or confined spaces. This allows for normal operation even in low-light conditions.
