Operating Instructions and Adjustments
The EUREKA ERGONOMIC ERK-OC12-B chair offers multiple adjustments to customize your seating experience for optimal comfort and ergonomic support.

1. Seat Height Adjustment:
To adjust the seat height, locate the lever on the right side, beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up and pull the lever up. Release the lever at the desired height.
2. Adaptive Lumbar Support:
This chair features an innovative auto-following adaptive lumbar support. The lumbar support automatically adjusts to your sitting position. To fine-tune the support strength:
- Increase Support: Turn the knob on the side of the backrest clockwise.
- Reduce Support: Rotate the knob counter-clockwise.
Image: Visual guide on adjusting the lumbar support. Turning the knob clockwise increases support, while counter-clockwise reduces it, helping to relieve back pressure.
3. Backrest Tilt Function:
The backrest can be tilted and locked at multiple angles (96°, 106°, 116°, 126°). Locate the tilt lever, typically on the left side beneath the seat.
- Unlock Tilt: Pull the lever outwards.
- Recline: Lean back to the desired angle.
- Lock Tilt: Push the lever inwards to lock the backrest in position.

Maintenance and Care
Proper maintenance ensures the longevity and optimal performance of your EUREKA ERGONOMIC office chair.
- Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners, as these can damage the mesh, fabric, or frame.

- Fastener Check: Every few months, check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and prevent squeaks.
- Mesh Inspection: Inspect the mesh backrest and seat for any signs of wear or damage.
Troubleshooting
If you encounter any issues with your EUREKA ERGONOMIC office chair, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |

| Chair does not adjust height | Gas lift malfunction or lever not engaged | Ensure the height adjustment lever is fully engaged. If the issue persists, the gas lift may need replacement. Contact customer support. |
| Chair is unstable or wobbly | Loose fasteners or damaged base/casters | Check and tighten all screws and bolts, especially those connecting the seat to the mechanism and the base. Inspect the base and casters for damage. |
