Operating Instructions
Height Adjustment
The SONICAKE QDT-30 features a hydraulic mechanism for quick and effortless height adjustment.
- To Raise the Seat: While standing, pull the hydraulic lever located under the seat upwards. The seat will automatically rise. Release the lever when the desired height is reached.
- To Lower the Seat: While seated, pull the hydraulic lever upwards. The seat will lower under your body weight. Release the lever when the desired height is reached.
The adjustable height range is approximately 45 cm (17.7 inches) to 60 cm (23.6 inches).

Backrest Adjustment
The backrest can be adjusted for optimal ergonomic support.
- To Adjust Backrest Position: Loosen the backrest attachment screws located on the underside of the seat. Adjust the backrest forwards or backwards to your preferred position. Once adjusted, securely tighten the screws to lock the backrest in place.
- The backrest is designed to conform to the natural curvature of the human body, providing excellent lumbar support.

Maintenance
- Cleaning: Wipe the leather fabric seat and backrest with a soft, damp cloth. For stubborn stains, use a mild soap solution and dry thoroughly. Avoid harsh chemicals or abrasive cleaners.
- Hardware Check: Periodically check all screws and bolts, especially those securing the backrest and the seat to the base, to ensure they remain tight. Tighten if necessary.
- Hydraulic System: The hydraulic system is generally maintenance-free. If you notice any issues with height adjustment, ensure the lever is functioning correctly and there are no obstructions.
- Anti-slip Feet: Ensure the anti-slip rubber pads on the base legs are clean and free from debris to maintain optimal grip.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Seat does not raise or lower smoothly. | Hydraulic lever stuck or obstructed; hydraulic cylinder issue. | Check if the hydraulic lever moves freely. Ensure no obstructions are preventing movement. If the issue persists, contact customer support. |
| Drum throne feels unstable or wobbly. | Loose assembly screws; uneven surface; damaged base. | Ensure all assembly screws (especially backrest and seat-to-base connections) are securely tightened. Verify the drum throne is on a flat, level surface. Inspect the base legs for any damage. |
| Backrest moves or feels loose. | Backrest attachment screws are loose. | Tighten the backrest attachment screws firmly. |
