4. Operating Instructions

Your Kassipo office chair is designed with several adjustable features to enhance comfort and support.

Adjusting Seat Height:

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 slightly and pull the lever up. Release the lever at your desired height.

Rocking Function and Tilt Lock:

The chair features a rocking function allowing the backrest to recline up to 125 degrees. To activate the rocking function, pull the lever on the left side beneath the seat outwards. Push the lever inwards to lock the chair in an upright position. The tension of the rocking motion can be adjusted by turning the round knob located at the front center beneath the seat.

Flip-Up Armrests:

The armrests can be flipped up by rotating them upwards by 90 degrees. This feature allows the chair to be pushed closer to a desk or stored compactly when not in use.

5. Maintenance

Proper care and maintenance will extend the life of your Kassipo office chair.

• Cleaning: The manufacturer recommends dry cleaning for the fabric components. For general cleaning, wipe surfaces with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Inspection: Periodically inspect all screws and bolts to ensure they remain tight. Re-tighten as necessary.
• Wheels: Keep the wheels free of debris (e.g., hair, dust) to ensure smooth mobility.

6. Troubleshooting

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

• Chair does not adjust height: Ensure the gas lift lever is fully engaged and the gas lift cylinder is properly seated in the base and seat mechanism. If the issue persists, the gas lift may need replacement.
• Chair feels wobbly or loose: Check all assembly screws and bolts. Tighten any loose connections. Ensure the chair is on a flat, stable surface.
• Wheels do not roll smoothly: Inspect the wheels for any trapped debris (hair, lint, etc.) and remove it. Ensure the wheels are securely inserted into the base. If using on carpet, a chair mat may improve mobility.
• Backrest does not rock or lock: Verify the tilt lock lever is in the correct position. Adjust the rocking tension knob to ensure it is not overtightened or too loose.
