6. Operating Instructions
6.1 Selecting Speed
The drill features a 2-speed gearbox. Use the speed selector switch located on top of the drill:
- Position 1 (Low Speed, 0-500 RPM): Ideal for screwdriving and drilling large diameter holes in softer materials.
- Position 2 (High Speed, 0-1800 RPM): Suitable for drilling small diameter holes and for hammer drilling applications.

Figure 6: Speed and torque adjustment.
6.2 Adjusting Torque
The torque adjustment ring allows you to select from 20 torque settings for screwdriving, plus a drilling mode and a hammer drilling mode. Rotate the ring to the desired setting:
- Settings 1-20: For driving screws. Lower numbers are for smaller screws or softer materials; higher numbers are for larger screws or harder materials.
- Drill Symbol: For general drilling without torque limitation.
- Hammer Symbol: For hammer drilling into masonry or concrete.
6.3 Selecting Operating Mode (3-in-1 Functionality)
The drill offers three primary modes:
- Drilling Mode: For drilling into wood, metal, plastic, etc.
- Screwdriving Mode: For driving and removing screws.
- Impact Drilling Mode: For drilling into hard materials like concrete or masonry.

Figure 7: The three operating modes: Drilling, Impact Drilling, and Screwdriving.
6.4 Forward/Reverse Rotation
The forward/reverse selector switch is located above the trigger. Push it to the left for forward rotation (tightening screws, drilling) and to the right for reverse rotation (loosening screws, removing bits).
