5. Opsætning
5.1 Batteriopladning
The 12V Lithium-Ion battery requires approximately 1 hour for a full charge using the provided fast charger.
- Connect the charger to a standard power outlet. The charger indicator light will show its status.
- Plug the barrel connector of the charger into the charging port on the battery.
- The indicator light on the charger will change to indicate charging status (e.g., red for charging, green for fully charged).
- Once fully charged, disconnect the charger from the battery and the power outlet.

5.2 Installation og fjernelse af batteri
- Installation: Align the battery with the base of the drill handle and slide it in until it clicks securely into place.
- Fjernelse: Press the two release buttons on the sides of the battery pack and pull the battery downwards to remove it from the drill.
5.3 Chuck Adjustment and Bit Installation
The SEYVUM C11 features a 3/8-inch keyless chuck for easy bit changes.
- Åbn chuck: Rotate the chuck counter-clockwise until the jaws are wide enough to insert your desired drill bit or screwdriver bit.
- Indsæt bit: Insert the bit into the chuck, ensuring it is centered and fully seated.
- Spænd borepatronen: Rotate the chuck clockwise to securely tighten the jaws around the bit. Ensure the bit is firmly held to prevent slippage during operation.

6. Betjeningsvejledning
6.1 Tænd/sluk og variabel hastighed
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. Releasing the trigger turns the drill off.
6.2 Frem/Baglæns kontakt
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 Momentjustering (koblingsindstillinger)
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 hastighedsvalg
The drill features a 2-speed gearbox. Use the switch on top of the drill to select between:
- Hastighed 1 (0-450 o/min): Lower speed, higher torque, ideal for driving screws and larger diameter drilling.
- Hastighed 2 (0-1500 o/min): 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 Drilling and Driving Techniques
- Generel brug: Tryk konstant og jævnt. Brug ikke for meget kraft på boremaskinen.
- Screws Driving: Use lower speed (Speed 1) and adjust torque to prevent stripping.
- Træboring: Use appropriate wood drill bits. Higher speeds (Speed 2) are generally suitable.
- Metalboring: 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.
