4.1 Accensione/Spegnimentu è Cuntrollu di Velocità
- The drill is activated by pressing the variable speed trigger switch.
- The speed of the drill is controlled by the amount of pressure applied to the trigger. Pressing lightly results in lower speed, while pressing fully results in maximum speed.
- Rilasciate u grillettu per spegne u trapanu.
4.2 Rotazione avanti/indietro

Figura 4.2: Un primu pianu view of the drill's forward/reverse selector switch, positioned above the trigger for easy access and directional control.
- The forward/reverse selector switch is located above the trigger.
- Push the switch to the left for forward rotation (drilling/driving screws in).
- Push the switch to the right for reverse rotation (removing screws).
- When the switch is in the center position, the trigger is locked, preventing accidental startup.
4.3 Gearbox Speed Selection
- The 2-speed gearbox selector switch is located on top of the drill.
- Posizione 1 (Bassa velocità): Per applicazioni à coppia elevata, cum'è l'avvitamentu di viti di grandi dimensioni o a perforazione di fori di grandi dimensioni.
- Posizione 2 (Alta Velocità): Per una perforazione più rapida in materiali più morbidi o fori più chjuchi.
- Always ensure the drill is stopped before changing gear speeds.
4.4 Torque and Mode Selection
- The torque adjustment ring is located behind the chuck.
- Rotate the ring to select the desired torque setting (1-21) for driving screws. Lower numbers are for smaller screws and softer materials, higher numbers for larger screws and harder materials.
- For drilling into wood or metal, select the drill symbol (drill mode).
- For drilling into masonry or concrete, select the hammer drill symbol (hammer drill mode).
