5. Safety Information
Always exercise caution when working with tools and hardware. Wear appropriate personal protective equipment, such as safety glasses. Keep small parts and screws away from children. Ensure cabinet doors are securely attached before use to prevent injury.
6. Setup and Installation
These hinges are designed for frameless cabinets. Installation on face frame cabinets requires a spacer block to be mounted on the inside of the cabinet sidewall to align with the face frame surface.
6.1 Preparing the Cabinet Door
- Determine the hinge cup drilling positions on the cabinet door. For 110-degree hinges, the standard drilling distance from the door edge is typically 3mm to 6mm, but always refer to a drilling template for precise measurements.
- Using a 35mm Forstner bit, drill the hinge cup holes to the recommended depth (usually 13mm). Ensure holes are clean and free of debris.
- Place the hinge cup into the drilled hole and secure it with the provided screws.

6.2 Attaching Mounting Plates to Cabinet
- Mark the positions for the mounting plates on the inside of the cabinet side panel. The vertical position of the mounting plates should align with the hinges on the door.
- Pre-drill pilot holes for the mounting plate screws. Using a self-centering drill bit is recommended for accuracy.
- Secure the mounting plates to the cabinet side panel using the provided screws. Ensure they are level and correctly spaced.

6.3 Attaching the Door to the Cabinet
- Align the hinge arm with the mounting plate.
- Press the hinge arm onto the mounting plate until it clicks into place. This indicates a secure connection.
- Test the door's movement to ensure it opens and closes smoothly.
7. Operating and Adjustment
The Blumotion hinges offer 3-dimensional adjustment to achieve perfect door alignment.
7.1 3-Dimensional Adjustment
- Side-to-Side Adjustment: Use the front screw on the hinge arm to move the door left or right. Turning clockwise moves the door towards the hinge side, counter-clockwise moves it away.
- Depth Adjustment: Use the rear screw on the hinge arm to move the door in or out relative to the cabinet frame. This adjusts the gap between the door and the cabinet.
- Height Adjustment: The mounting plate typically has elongated holes for height adjustment. Loosen the mounting plate screws slightly, adjust the door up or down, and then re-tighten the screws.

7.2 Disabling Blumotion Soft-Close
Each hinge features a small switch on the hinge arm that allows you to deactivate the Blumotion soft-close function. This can be useful for lighter doors or if you prefer a traditional closing action. Simply slide the switch to the 'off' position to disable, and 'on' to re-enable.
8. Maintenance
To ensure optimal performance and longevity of your Blumotion hinges:
- Cleaning: Wipe hinges periodically with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Inspection: Annually check all screws for tightness. Re-tighten if necessary, but do not overtighten.
- Lubrication: The Blumotion mechanism is maintenance-free and does not require lubrication.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door is misaligned (gaps, uneven). | Incorrect hinge adjustment. | Use the 3-dimensional adjustment screws (side-to-side, depth, height) to realign the door. Refer to Section 7.1. |
| Soft-close not working or door slams. | Blumotion mechanism deactivated or damaged. | Check the Blumotion switch on each hinge arm (Section 7.2). Ensure it is in the 'on' position. If still not working, the hinge may need replacement. |
| Door sags or feels loose. | Loose mounting screws. | Tighten all screws on both the hinge cup and the mounting plate. Do not overtighten. |
