Setup and Installation
This section outlines the steps for installing the HOWHY 90° Rotating Table Hinges. Ensure you have the necessary tools (e.g., drill, screwdriver, measuring tape) and follow all safety precautions.
Preparation:
- Identify the desired location for the rotating table extension.
- Ensure the furniture piece (cabinet or desk) meets the minimum size requirements:
- Minimum cabinet width for 1.5-inch universal wheels: 1.57 inches, with 1.37 inches clearance off the ground.
- Minimum cabinet width for plastic universal wheels: 2 inches, with 0.35 inches clearance off the ground.
- Minimum thickness of rotating plate: 0.63 inches.
- Vertical plate thickness minimum: 2 inches.
- Reserve at least 0.2 inches space on the right side of the rotating plate.
- Leave 0.6 inches space on the left side of the cabinet for the hinge.
- Mark the precise drilling points for the hinge and wheels.

Installation Steps:
- Install the Swivel Hardware Hinge:
Position the swivel hinge on the designated surface of your furniture. Ensure it is aligned correctly for a left-opening rotation (for model HY-XXFXK-lif). Mark the screw holes. Drill pilot holes if necessary, then secure the hinge using the provided screws.

- Prepare the Rotating Table/Panel:
Attach the other half of the swivel hinge to the rotating table or panel. Ensure the alignment is precise to allow for smooth 90-degree rotation. Secure with screws.
- Install the Wheels:
Depending on your furniture design and desired load capacity, install either the 1.5-inch universal wheels or the plastic universal wheels on the bottom of the movable table/cabinet. For the plastic universal wheels, ensure four 1.18-inch diameter, 0.82-inch deep round holes are prepared in the bottom of the cabinet. For directional wheels, ensure they are oriented to support the intended movement path.

- Test Movement:
Once all components are securely fastened, gently test the rotation of the table to ensure smooth movement and proper alignment. Adjust screws if any resistance or misalignment is observed.
Operating Instructions
The HOWHY 90° Rotating Table Hinges allow for easy transformation of your furniture to adapt to various needs and optimize space. The left-opening design (for model HY-XXFXK-lif) facilitates a counter-clockwise rotation from its closed position.
How to Rotate the Table:
- To Extend: Gently pull the movable table/cabinet outwards from its closed position. The hinge mechanism will guide the table as it rotates 90 degrees to form an L-shape with the main furniture piece.
- To Retract: Push the movable table/cabinet back towards the main furniture piece. The hinge will guide it smoothly back into its compact, closed position.
The integrated wheels ensure smooth and effortless movement across various floor surfaces. Always ensure the path is clear before rotating the table.

Maintenance
Proper maintenance will ensure the longevity and smooth operation of your HOWHY Rotating Table Hinges.
- Cleaning: Wipe the hinge and wheel components periodically with a soft, damp cloth to remove dust and debris. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Lubrication: If the hinge mechanism or wheels begin to feel stiff or noisy, apply a small amount of silicone-based lubricant to the moving parts. Do not over-lubricate.
- Fastener Check: Periodically check all screws and fasteners to ensure they remain tight. Re-tighten if necessary to prevent wobbling or instability.
- Wheel Inspection: Inspect the wheels for any signs of wear or damage. Replace severely worn wheels to maintain smooth movement and prevent floor damage.
Troubleshooting
If you encounter issues with your HOWHY Rotating Table Hinges, refer to the following common problems and solutions:
- Table is difficult to rotate or feels stiff:
- Check for obstructions in the path of rotation.
- Ensure all screws are not overtightened, which can impede movement.
- Apply a small amount of lubricant to the hinge mechanism and wheel axles.
- Verify that the furniture dimensions meet the minimum requirements for smooth operation (refer to "Setup and Installation").
- Table wobbles or is unstable:
- Ensure all screws securing the hinge and wheels are tightly fastened.
- Verify that the furniture structure itself is stable and level.
- Check if the weight on the table exceeds the specified load limit (90 lbs for 1.5-inch wheels, 50 lbs for plastic wheels).
- Wheels are not rolling smoothly or are noisy:
- Clean any hair, dust, or debris from around the wheel axles.
- Apply lubricant to the wheel axles.
- Inspect wheels for damage or excessive wear; replace if necessary.
- Table does not align correctly when extended or retracted:
- Re-check the hinge installation for proper alignment. Slight adjustments to screw tightness or hinge position may be needed.
- Ensure the furniture pieces are level and on an even surface.
