5. Setup and Installation
The POJJO HG90-00100 hinges are designed for installation on 3/4-inch thick wood panels, typically for sink front tip-out trays or similar applications. Precise measurements are critical for proper function and alignment.
Tools Required:
- Measuring Tape or Ruler
- Pencil
- Drill with appropriate drill bits for pilot holes
- Screwdriver (Phillips head recommended)
- Safety Glasses
Installation Steps:
- Prepare the Cabinet and Panel: Ensure the cabinet opening and the tip-out panel (door) are clean and free of obstructions. The panel should be 3/4-inch thick for optimal fit.
- Determine Hinge Placement: The hinges are typically mounted on the inside of the cabinet frame and the back of the tip-out panel. Carefully measure and mark the desired location for each hinge. The scissor design requires sufficient clearance for the panel to pull out and down.
- Mount Hinges to Cabinet Frame:
- Position one hinge on the inside of the cabinet frame, aligning it with your marks.
- Using a pencil, mark the screw hole locations.
- Drill pilot holes at the marked locations. Pilot holes should be slightly smaller than the screw diameter to prevent wood splitting.
- Secure the hinge to the cabinet frame using the provided screws or suitable alternatives. Do not overtighten.
- Repeat for the second hinge on the opposite side of the cabinet frame.
- Attach Hinges to Tip-Out Panel:
- With the hinges attached to the cabinet, carefully align the tip-out panel with the hinges. The panel will attach to the flat, triangular portion of the hinge.
- Mark the screw hole locations on the back of the tip-out panel.
- Remove the panel and drill pilot holes at the marked locations.
- Re-align the panel with the hinges and secure it using screws. Ensure the panel is level and operates smoothly.
- Test Operation: Gently open and close the tip-out panel to ensure smooth movement and that it locks securely at the 90-degree open position. Adjust screw tightness if necessary to optimize movement without binding.

6. Operation
Once installed, the POJJO HG90-00100 hinge allows the attached panel to pivot outwards and downwards, achieving a full 90-degree open position. This mechanism is designed to provide ample access to the space behind the panel, such as a sink front tray. To open, gently pull the panel outwards and downwards until it reaches its fully extended and locked 90-degree position. To close, push the panel upwards and inwards until it is flush with the cabinet frame.
7. Maintenance
The POJJO HG90-00100 hinges are constructed from durable chrome-plated steel and require minimal maintenance. Periodically check the screws for tightness and re-tighten if necessary to ensure continued smooth operation. Clean the hinges with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals, as these can damage the chrome finish.
8. Troubleshooting
- Panel does not open or close smoothly:
- Check for obstructions behind the panel or within the hinge mechanism.
- Ensure all mounting screws are tightened appropriately. Over-tightening or under-tightening can affect movement.
- Verify that the hinges are installed level and parallel to each other. Misalignment can cause binding.
- Panel sags or feels loose:
- Inspect all mounting screws for looseness and tighten them.
- If screws are stripped, consider using larger screws or wood anchors for a more secure fit.
- Ensure the wood panel itself is not damaged or warped.
