Maintenance

Troubleshooting
If you encounter any issues with your DUMOS Overbed Table, refer to the following common problems and solutions:
- Table is unstable or wobbly: Ensure all assembly screws are securely tightened. Check that the base is on a flat, even surface. If parts were missing during assembly, contact customer support for replacements.
- Difficulty adjusting height: Verify that the pneumatic lift lever is fully engaged and not obstructed. If the mechanism feels stiff, ensure no debris is interfering with the column.
- Wheels do not roll smoothly: Check for any debris or hair caught in the casters. While designed for smooth movement, very thick carpets may reduce ease of mobility.
