5. Maintenance
To maintain the quality and longevity of your Dowinx gaming chair, follow these simple maintenance guidelines:
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the fabric.
- Regular Checks: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
- Fabric Care: The upgraded tech fabric combines cotton-linen and Dutch velvet. Avoid prolonged exposure to direct sunlight to prevent fading.
6. Troubleshooting
If you encounter any issues with your chair, refer to the following common troubleshooting tips:
- Chair does not raise/lower: Ensure the gas lift lever is fully engaged and that there are no obstructions. If the issue persists, the gas lift cylinder may need replacement.
- Backrest does not recline/lock: Check that the recline lever is functioning correctly and is not jammed. Ensure no foreign objects are obstructing the reclining mechanism.
- Massage function not working: Verify that the USB cable is securely connected to a working USB power source. Try a different USB port or power bank.
- Squeaking noises: Check and tighten all assembly screws. Applying a small amount of lubricant to moving parts may also help.
