6. Gebruiksaanwijzing
6.1 In-/uitschakelen en variabele snelheid
The drill is activated by pressing the variable speed trigger. The speed of rotation is controlled by the amount of pressure applied to the trigger. ReleasinMet de trekker wordt de boormachine uitgeschakeld.
6.2 Vooruit/achteruit schakelaar
The forward/reverse switch is located above the trigger. Push the switch to the left for forward rotation (clockwise) for drilling and driving screws. Push it to the right for reverse rotation (counter-clockwise) for removing screws or freeing stuck bits. Ensure the switch is in the center position to lock the trigger and prevent accidental startup.
6.3 Koppelafstelling (Koppelingsinstellingen)
The 20+1 position clutch allows you to select the appropriate torque setting for your task, preventing over-driving screws or damaging materials. Rotate the numbered ring behind the chuck to adjust the torque. The higher the number, the greater the torque. The drill icon setting is for maximum torque, suitable for drilling.

6.4 Snelheidsselectie
The drill features a 2-speed gearbox. Use the switch on top of the drill to select between:
- Snelheid 1 (0-450 RPM): Lower speed, higher torque, ideal for driving screws and larger diameter drilling.
- Snelheid 2 (0-1500 RPM): Higher speed, lower torque, ideal for smaller diameter drilling in wood or metal.

Image: Visual representation of the two variable speed settings: 0-450 RPM for screws driving and 0-1500 RPM for drilling.
6.5 Boor- en aandrijftechnieken
- Algemeen gebruik: Oefen constante, gelijkmatige druk uit. Forceer de boor niet.
- Screws Driving: Use lower speed (Speed 1) and adjust torque to prevent stripping.
- Houtboren: Use appropriate wood drill bits. Higher speeds (Speed 2) are generally suitable.
- Metaalboren: Use appropriate metal drill bits. Start with a pilot hole for larger bits. Use lower speeds (Speed 1) and apply cutting oil to prevent overheating.
