4.2 Forward/Reverse Rotation
Use the forward/reverse selector (5) to choose the direction of rotation. Push it to the left for forward (drilling/driving) and to the right for reverse (removing screws). The center position locks the trigger for safety.
4.3 Speed Settings (Gear Selector)
The tool has two mechanical speed settings, selected via the speed selector switch (4):
- Gear 1 (Low Speed): For high torque applications, such as driving large screws or drilling large holes in wood. (Max 400 RPM)
- Gear 2 (High Speed): For faster drilling in softer materials or smaller holes. (Max 1500 RPM)
4.4 Mode and Torque Adjustment
The mode selector (3) and torque adjustment collar (2) allow you to optimize the tool for different tasks:
- Driving Mode (Screw Icon): Use the torque adjustment collar to select the desired torque setting (1-19). Lower numbers for smaller screws, higher numbers for larger screws. This prevents over-tightening and stripping.
- Drilling Mode (Drill Bit Icon): For drilling into wood, metal, or plastic. The clutch is disengaged, providing maximum torque.
- Percussion/Hammer Drilling Mode (Hammer Icon): For drilling into masonry, brick, or concrete. Combines rotation with a hammering action.
