5. Operating Instructions: Height Adjustment

The Vangoa PB-1 Piano Bench offers adjustable height settings to accommodate various users and instruments.

1. Loosen Knobs: Locate the two adjustment knobs on the side of each leg. Turn them counter-clockwise to loosen them.
2. Adjust Height: Carefully pull the inner leg sections up or push them down to your desired height. The bench features multiple pre-drilled holes for height settings.
3. Secure Height: Once the desired height is achieved, align the holes in the inner and outer leg sections. Re-insert the adjustment knobs and turn them clockwise until they are firmly tightened. Ensure both knobs are equally secure to maintain stability.

The bench offers four seating heights, ranging from approximately 18.5 inches (47 cm) to 23.6 inches (60 cm).

6. Maintenance

• Cleaning: Wipe the bench with a dry cloth to remove dust and dirt. For the PU leather cushion, a damp cloth can be used for spills, then wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically check all screws and adjustment knobs to ensure they remain tight. Re-tighten if necessary.
• Storage: When not in use for extended periods, store the bench in a dry, cool place away from direct sunlight to preserve the material. The foldable design allows for easy storage and transport.

7. Troubleshooting

• Bench is Unstable:
  • Ensure all assembly screws are tightened.
  • Verify that both height adjustment knobs are securely tightened.
  • Check that the bench is placed on a flat, even surface. The non-slip ABS end caps are designed to protect floors and provide grip.
• Difficulty Adjusting Height:
  • Ensure the adjustment knobs are fully loosened before attempting to change the height.
  • If the legs are stiff, gently wiggle them while adjusting. Do not force the adjustment.
  • Confirm that the inner leg sections are aligned with the pre-drilled holes for the knobs to re-engage properly.
• Bench Does Not Reach Stated Maximum Height:
  • The maximum height is 23.6 inches. Ensure the legs are fully extended to the highest possible hole and the adjustment knobs are securely fastened.
  • If you suspect a manufacturing defect preventing full extension, contact customer support.
