6. Operating Instructions
6.1. Powering On/Off and Variable Speed Control
The tool is activated by pressing the trigger switch (Figure 2, item 7). The speed is variable and controlled by how much you depress the trigger. Pressing lightly results in lower speed, while pressing fully results in maximum speed.

6.2. Forward/Reverse Rotation
The forward/reverse buttons (Figure 2, item 6) control the direction of rotation. Push the button to the left for forward rotation (tightening screws) and to the right for reverse rotation (loosening screws). The center position locks the trigger for safety.
6.3. High/Low Speed Selection
Use the High/Low speed switch (Figure 2, item 3) to select the appropriate speed range for your task:
- Low Speed (0-400rpm): Ideal for high-torque applications like driving large screws or drilling into hard materials.
- High Speed (0-1500rpm): Suitable for fast drilling in softer materials or smaller screws.
