Setup and Assembly

Assembly is required for this chair. All necessary hardware and tools are included. Follow these steps for proper assembly:

1. Attach Casters to Base: Insert each of the five casters into the holes at the end of each leg of the chair base. Push firmly until they click into place.
2. Insert Gas Lift: Place the gas lift cylinder into the center hole of the assembled base.
3. Attach Seat Plate to Seat: Align the seat plate mechanism with the pre-drilled holes on the underside of the chair seat. Ensure the front of the seat plate faces the front of the seat. Secure with the provided screws and Allen wrench.

Operating Instructions

Your ergonomic task chair features several adjustments to customize your seating experience:

• Seat Height Adjustment: To raise the seat, lift the lever located under the right side of the seat while taking your weight off the chair. To lower the seat, lift the lever while remaining seated. Release the lever at the desired height.
• Tilt Tension Control: The round knob under the front-center of the seat controls the resistance of the chair's tilt. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
• Upright Tilt Lock: The lever under the left side of the seat allows you to lock the chair in an upright position or enable the tilt function. Push the lever in to lock the backrest upright, and pull it out to allow the chair to recline.

Maintenance

To maintain the appearance and functionality of your chair:

• Cleaning: Spot clean the fabric with a mild detergent and a damp cloth. Do not use abrasive cleaners or solvents.
• Inspection: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
• Casters: Keep casters free of debris to ensure smooth movement.

Troubleshooting

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

• Chair does not adjust height: Ensure the gas lift lever is fully engaged or disengaged as required. If the issue persists, the gas lift cylinder may need replacement.
• Chair wobbles: Check all assembly screws and bolts to ensure they are securely tightened. Ensure the base is properly seated on the gas lift.
• Casters do not roll smoothly: Inspect casters for trapped debris (hair, lint, etc.) and clean them. Ensure casters are fully inserted into the base.
• Backrest does not recline or is too loose/tight: Adjust the tilt tension knob located under the seat. Ensure the upright tilt lock lever is in the correct position for reclining.
