Operating Instructions
1. Selecting Speed
The drill features a 2-speed selector switch located on top of the drill housing:
- Position 1 (Low Speed): 0-550 RPM, ideal for high torque applications like driving screws or drilling larger holes in softer materials.
- Position 2 (High Speed): 0-2000 RPM, suitable for fast drilling in wood or metal.

2. Adjusting Torque (Clutch Setting)
The 22+1 torque setting ring allows you to adjust the amount of torque applied. This prevents over-driving screws and protects the workpiece. The "+1" setting is for drilling mode, which bypasses the clutch for maximum power.
- Rotate the torque adjustment ring to the desired setting. Lower numbers are for smaller screws or softer materials. Higher numbers are for larger screws or harder materials.
- For drilling, select the drill icon setting (usually the highest number or a dedicated drill symbol).

3. Forward/Reverse Rotation
The forward/reverse switch is located above the trigger. Push it left for forward rotation (drilling/driving screws) and right for reverse rotation (removing screws/bits). The center position locks the trigger for safety.
4. Variable Speed Trigger
The trigger provides variable speed control. Pressing the trigger further increases the speed. This allows for precise control during operation.

5. LED Work Light
The integrated LED work light illuminates the work area when the trigger is pressed, improving visibility in dimly lit conditions.
