5. Configuració
5.1 Càrrega de la bateria
- Connect the Type-C charging cable to the charging port on the drill.
- Connect the other end of the cable to a compatible power adapter (5V=2A, 9V=2A, or 12V=2A).
- The digital display will indicate charging status. A full charge takes approximately 2 hours.
- Assegureu-vos que la temperatura de càrrega estigui entre 5 °C i 40 °C.
5.2 Instal·lació/canvi de bits
- Ensure the drill is powered off and the reverse/lock button is in the locked (middle) position to prevent accidental startup.
- Gireu el mandril en sentit antihorari per obrir les mordasses.
- Insert the desired drill bit or screwdriver bit into the chuck. Ensure it is seated firmly. For screwdriver bits, you may use the magnetic extension rod for added reach.
- Twist the chuck clockwise to tighten the jaws securely around the bit. The ratchet self-locking chuck design ensures a tight occlusion.
- To remove a bit, twist the chuck counter-clockwise until the jaws open, then pull the bit out.
