4.1 Yn-/útskeakelje en snelheidsregeling
- 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.
- Release the trigger to turn off the drill.
4.2 Rotaasje foarút/efterút

Figuer 4.2: In close-up view of the drill's forward/reverse selector switch, positioned above the trigger for easy access and directional control.
- De foarút/efterút-seleksjeskeakel sit boppe de trekker.
- Push the switch to the left for forward rotation (drilling/driving screws in).
- Druk de skeakel nei rjochts foar omkearde rotaasje (skroeven fuortsmite).
- As de skeakel yn 'e middelste posysje stiet, is de trekker blokkearre, wêrtroch't tafallich starten foarkomt.
4.3 Gearbox Speed Selection
- The 2-speed gearbox selector switch is located on top of the drill.
- Posysje 1 (Lege snelheid): Foar tapassingen mei hege koppel, lykas it yndraaien fan grutte skroeven of it boarjen fan grutte gatten.
- Posysje 2 (Hege snelheid): For faster drilling in softer materials or smaller holes.
- 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).
5. Underhâld
5.1 Cleaning
- Regularly clean the ventilation openings on the drill to prevent overheating.
- Brûk in sêft, damp doek om de bûtenkant fan it ark ôf te feegjen. Brûk gjin agressive gemikaliën of skurende reinigingsmiddels.
- Hâld de klauwkaken skjin en frij fan pún foar optimale bitgrip.
5.2 Batterij Soarch
- Bewarje batterijen yn in koel, droech plak fuort fan direkte sinne en ekstreme temperatueren.
- Bewarje batterijen net foar langere perioaden yn in ûntladen steat. Laad se regelmjittich op as se net yn gebrûk binne.
- Stel batterijen net bleat oan wetter of focht.
5.3 Opslach
- Store the drill, battery, and charger in the provided carrying case in a dry, secure location out of reach of children.
- Ensure the battery is removed from the drill before storage.
