- Position New Hinges: Place the new toilet seat hinges into the mounting holes on the toilet bowl. Ensure the hinges are aligned correctly.
- Secure Hinges: From the underside of the toilet bowl, attach the washers and nuts to the bolts extending from the hinges. Hand-tighten first to allow for minor adjustments.

- Final Tightening: Once aligned, fully tighten the nuts using an adjustable wrench or pliers. Be careful not to overtighten, which could damage the porcelain.

Maintenance and Care
Proper care will ensure the longevity and appearance of your toilet seat.
- Cleaning: Clean the toilet seat regularly with a soft cloth, warm water, and a mild, non-abrasive soap.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, scouring pads, strong acids, alkalis, or chlorine-based products, as these can damage the Duroplast surface and hinges.
- Drying: After cleaning, wipe the seat dry with a soft, clean cloth to prevent water spots.
- Hinge Care: Periodically check the tightness of the hinge bolts and tighten if necessary to prevent wobbling.
Troubleshooting
- Seat is Loose or Wobbles:
- Check the mounting nuts underneath the toilet bowl. Tighten them securely with an adjustable wrench or pliers. Do not overtighten.
- Ensure the hinges are correctly seated in the mounting holes.
- Seat Does Not Align Properly:
- Loosen the mounting nuts slightly, adjust the seat position until it is centered on the bowl, then re-tighten the nuts.
- Stains on the Seat:
- For minor stains, use a mild soap and water solution with a soft cloth.
- Avoid abrasive cleaners, as they can scratch the Duroplast surface.
