Operating Instructions (Adjustments)

The Diablo V-Commander chair offers multiple adjustment options to customize your seating experience for optimal ergonomics and comfort.

1. Seat Height Adjustment

Use the lever located under the seat to adjust the seat height. Pull the lever up to raise the seat; release it at the desired height. To lower, pull the lever up while seated.

2. Backrest Tilt and Recline Mechanism

The integrated tilt mechanism allows for dynamic movement and recline. Adjust the tension of the recline using the knob under the seat. The backrest can be locked in various positions, including upright (90°), relaxed (120°), and reclined (140°).

• Depth Adjustment: Slide the armrest pad forward or backward.
• Pivot Adjustment: Rotate the armrest pad left or right.

Maintenance

• Cleaning: The mesh fabric material is waterproof and durable. For general cleaning, use a soft, damp cloth. For stains, spot clean with a mild fabric cleaner. Avoid harsh chemicals or abrasive materials.
• Inspection: Periodically check all screws, bolts, and moving parts for tightness and proper function. Tighten any loose fasteners.
• Wheel Care: The rubber wheels are designed to prevent scratches. Keep them free of debris to ensure smooth gliding.

Troubleshooting

If you encounter any issues with your Diablo V-Commander chair, please refer to the following common problems and solutions:

• Chair is unstable or wobbly: Ensure all assembly screws and bolts are securely tightened. Check that the base and gas lift are correctly installed.
• Adjustments are not working smoothly: Check for any obstructions in the adjustment mechanisms. Ensure levers and knobs are fully engaged or disengaged as required. If an adjustment feels stiff, apply a small amount of silicone-based lubricant to the moving parts (avoiding fabric).
• Gas lift not holding height: This may indicate a faulty gas lift. Contact customer support for assistance.
• Armrests are loose or not holding position: Verify that the armrest attachment screws are tight. For 3D armrests, ensure the internal locking mechanisms are engaging properly.
• Unusual noises (squeaking, creaking): Check for loose connections and tighten them. Lubricate moving parts with a silicone-based spray if necessary.

If the problem persists after attempting these solutions, please contact customer support.
