3. Installation Instructions
Follow these steps for proper installation of the YIDELAI 90-Degree Folding Lifting Spring Hinges:
- Unfold the Hinge: Fully unfold the spring hinge to its open position before beginning installation.
- Determine Placement: Identify the suitable installation position on your furniture piece (e.g., cabinet door, sofa bed frame). Ensure proper alignment for smooth operation.
- Initial Fastening: Secure the hinge with one or two screws initially. This allows for minor adjustments.
- Test Operation: Gently open and close the furniture component to observe if the hinge operates normally and smoothly. Adjust the position if necessary.
- Final Fastening: Once the position is confirmed and operation is smooth, install all remaining screws to fully secure the hinge.
Note: Screws are not included in the packaging due to varying material thicknesses of installation surfaces. Please use appropriate screws for your specific application.

4. Operation
The YIDELAI 90-Degree Folding Lifting Spring Hinge is designed for simple and reliable operation. When installed correctly, the hinge will allow the attached furniture component to open to an approximate 90-degree angle and hold that position. The spring mechanism assists in the lifting and folding action, providing support and stability.

5. Maintenance
To ensure the longevity and smooth operation of your YIDELAI spring hinges, consider the following maintenance tips:
- Regular Cleaning: Wipe down the hinges periodically with a soft, dry cloth to remove dust and debris.
- Lubrication: If the hinges begin to feel stiff, apply a small amount of silicone-based lubricant to the moving parts and pivot points. Avoid oil-based lubricants that can attract dust.
- Check Fasteners: Periodically inspect all screws to ensure they are tight. Loose screws can affect hinge performance and stability.
- Avoid Overloading: Do not exceed the intended load-bearing capacity of the hinges, as this can cause damage or premature wear.
6. Troubleshooting
If you encounter issues with your spring hinges, refer to the following common problems and solutions:
- Hinge feels stiff:
- Ensure the hinges are perfectly aligned during installation. Misalignment can cause stiffness.
- Apply a silicone-based lubricant to the pivot points.
- Hinge does not hold position:
- Verify that the hinges are correctly installed and all screws are tightened.
- Check if the load on the furniture component exceeds the hinge's capacity.
- Screws are loose:
- Tighten all screws. If screws repeatedly loosen, consider using slightly longer screws or wood glue in the screw holes (for wood applications) to improve grip.
