Operating Instructions
Your SENSE7 Spellcaster Senshi Edition XL Gaming Chair offers several adjustment options for personalized comfort:
- Seat Height Adjustment: To adjust the seat height (range 43-52 cm), pull the lever located under the right side of the seat upwards. While seated, lift your weight to raise the seat; to lower, remain seated and pull the lever. Release the lever to lock the height.
- Backrest Recline: The backrest can be reclined from 90 to 160 degrees. Pull the recline lever on the right side of the chair upwards and lean back to your desired angle. Release the lever to lock the backrest in position.
- Armrest Adjustment (FlowTechArm 2D): The 2D armrests allow for vertical height adjustment and horizontal extension. Use the button on the side of the armrest to adjust its height. To extend or retract the armrest pad, slide it forwards or backwards.
- Tilt Function: The chair features a tilt mechanism. To enable tilt, pull the lever under the left side of the seat outwards. To lock the tilt, push the lever inwards. The tension of the tilt can be adjusted by rotating the knob located under the front of the seat.

Maintenance
Proper maintenance will extend the life of your gaming chair:
- Cleaning: Wipe the synthetic leather surfaces with a soft, damp cloth. For stubborn stains, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Wheel Care: Periodically clean the wheels to remove dust, hair, and debris that may hinder smooth movement.
- Fastener Check: Every few months, check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability and safety.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the synthetic leather to fade or crack. Position the chair away from direct sunlight when possible.

Troubleshooting
If you encounter any issues with your chair, refer to the following common problems and solutions:
- Chair Squeaks:
Solution: Check all screws and bolts for tightness and retighten if loose. Apply a small amount of silicone lubricant to moving parts if the squeaking persists. - Chair Does Not Adjust Height:
Solution: Ensure the gas lift lever is fully engaged or disengaged. Check if the gas lift cylinder is properly seated in the star base and chair mechanism. If the issue persists, the gas lift may need replacement. - Wheels Do Not Roll Smoothly:
Solution: Inspect the wheels for accumulated debris (hair, dust, etc.) and clean them thoroughly. Ensure the wheels are securely inserted into the star base. - Backrest Does Not Recline/Lock:
Solution: Verify that the recline lever is functioning correctly and not obstructed. Check the connection points of the backrest to the seat base for any looseness.
