Operating Instructions

Your JUMMICO Executive Office Chair offers several adjustable features to customize your seating experience for optimal comfort and ergonomic support.

Adjustable Features:

• Height Adjustment: Locate the lever on the right side beneath the seat. To raise the seat, lift the lever while taking your weight off the chair. To lower the seat, lift the lever while remaining seated. Release the lever at your desired height.
• Tilt/Rocking Function: The same lever used for height adjustment also controls the tilt function. Pull the lever outwards to enable the rocking motion. Push the lever inwards to lock the chair in an upright position.
• Tilt Tension Control: A round knob located under the front of the seat allows you to adjust the tension of the rocking mechanism. Turn clockwise to increase tension (making it harder to rock) or counter-clockwise to decrease tension (making it easier to rock).
• 360° Swivel: The chair is equipped with a 360-degree swivel function, allowing for easy rotation and access to different areas of your workspace without needing to move the entire chair.

Maintenance

Proper care and maintenance will extend the life and appearance of your JUMMICO Executive Office Chair.

• Cleaning: The chair is upholstered with high-quality PU leather, which is waterproof and easy to clean. For general cleaning, wipe the surface with a soft, damp cloth. For spills, immediately wipe them up with a dry cloth to prevent staining. Avoid using harsh chemicals or abrasive cleaners.
• Hardware Check: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.
• Caster Care: Keep the casters free from hair, dust, and debris to ensure smooth rolling. You may occasionally need to clean them with a small brush or vacuum.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the PU leather to fade or crack. Position your chair away from direct sunlight when possible.

Troubleshooting

If you encounter any issues with your JUMMICO Executive Office Chair, please refer to the following common problems and solutions:

• Chair Squeaks: Check all bolts and screws and tighten them if loose. A small amount of silicone lubricant can be applied to moving parts if the squeaking persists.
• Difficulty Adjusting Height: Ensure the gas lift lever is fully engaged. If the chair still doesn't adjust, the gas lift cylinder may need replacement.
• Chair Does Not Roll Smoothly: Inspect the casters for any trapped debris (hair, dust, etc.) and clean them thoroughly. Ensure the chair is used on an appropriate surface.
• Chair Feels Unstable: Re-check all assembly connections to ensure they are tight and correctly installed. Ensure the chair is on a flat, even surface.

If these solutions do not resolve the issue, please contact JUMMICO customer support for further assistance.
