Maintenance
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the faux leather.
- Inspection: Periodically check all bolts and screws to ensure they remain tight. Re-tighten as necessary.
- Moving the Chair: When moving the chair, lift it rather than dragging it to prevent damage to the base or floor.
- Storage: Store the remote control in the designated side pocket when not in use.
Troubleshooting
- Chair is unstable: Ensure all assembly bolts are securely tightened. Check that the casters are properly inserted into the base. Ensure the chair is on a flat surface.
- Massage/Heat not working: Verify that the power cord is securely plugged into both the chair and a working electrical outlet. Check the remote control for battery issues if applicable (this model is wired, so check connections).
- Difficulty adjusting height: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift cylinder may need replacement.
- Squeaking noises: Apply a small amount of lubricant to moving parts or pivot points, avoiding contact with upholstery. Check for loose connections and tighten if necessary.
