Setup and Installation

These casters are designed for easy pull-and-snap installation. No tools are typically required for replacement.

1. Prepare the Chair: Turn your office chair upside down to access the existing caster wheels.
2. Remove Old Casters: Firmly pull each old caster wheel straight out from the chair base. They are usually held in place by friction. Some older or stubborn casters may require a gentle pry with a flathead screwdriver or pliers, but be careful not to damage the chair base.
3. Insert New Casters: Align the stem of the new hjh OFFICE caster wheel with the hole in the chair base. Push the caster stem firmly into the hole until it snaps securely into place. Ensure the stem is fully seated.
4. Verify Installation: Once all five casters are installed, turn the chair upright and test its movement. Ensure all wheels roll smoothly and are securely attached.

Compatibility Note: These casters feature a 7/16 inch (11mm) stem diameter, which is a common size for most office chairs. Please verify your chair's stem diameter before installation if you are unsure.

Operating Instructions

The hjh OFFICE 3-inch caster wheels are designed for optimal performance on hard floor surfaces. Their polyurethane coating provides several benefits:

• Floor Protection: The soft polyurethane material protects delicate hard floors (wood, laminate, tile, stone) from scratches and damage.
• Smooth Movement: Experience effortless gliding across hard surfaces, reducing strain and improving mobility.
• Quiet Operation: The material and design contribute to significantly quieter movement compared to standard hard plastic casters.
• Load-Dependent Brakes: These casters feature load-dependent brakes, meaning they will resist rolling when weight is applied to the chair, providing stability when seated. They will roll freely when the chair is unoccupied or when less weight is applied.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your caster wheels:

• Cleaning: Periodically inspect the wheels for accumulated dust, hair, or debris. Use a damp cloth to wipe the wheels clean. For stubborn debris, a small brush or tweezers can be used to carefully remove it from the axle area.
• Inspection: Check the casters regularly for any signs of wear, damage, or loose connections. Ensure the stems remain securely seated in the chair base.
• Avoid Harsh Chemicals: Do not use abrasive cleaners or harsh chemicals on the polyurethane surface, as this may degrade the material.

Troubleshooting

• Casters not rolling smoothly:
  • Check for debris (hair, lint, dirt) wrapped around the wheel axles. Clean thoroughly.
  • Ensure the casters are fully seated in the chair base. Re-insert if necessary.
  • Verify that the floor surface is clean and free of obstructions.
• Casters making noise:
  • Inspect for debris as mentioned above.
  • Ensure the casters are properly installed and not loose.
• Casters not fitting the chair:
  • Confirm your chair's stem diameter matches the 7/16 inch (11mm) specification of these casters. If the stem diameter is different, these casters will not be compatible.
