Operating Instructions
Chair Height Adjustment
To adjust the chair's height, locate the lever on the right side beneath the seat.
- To raise the seat: Lift the lever while taking your weight off the seat. The seat will rise automatically. Release the lever at the desired height.
- To lower the seat: Lift the lever while remaining seated. The seat will lower. Release the lever at the desired height.
Footrest Adjustment
The footrest ring can be adjusted vertically along the gas lift cylinder. Loosen the knob on the footrest, slide it to the desired height, and then tighten the knob securely to lock it in place.
Flip-up Armrests
The armrests can be flipped up 90 degrees to save space or allow the chair to be pushed closer to a desk. Simply lift the armrests upwards until they lock into the vertical position. To lower them, gently pull them down.
Lumbar Support Adjustment
The chair features a 2-inch adjustable lumbar support. To adjust, grasp the lumbar support mechanism on the backrest and slide it up or down to find the most comfortable position for your lower back.
Maintenance
- Cleaning: Wipe down the chair with a soft, damp cloth. For mesh and fabric areas, use a mild soap solution if necessary, and then wipe with a clean, damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Caster Care: Periodically check casters for hair or debris accumulation and clean as needed to ensure smooth rolling.
- Hardware Check: Every 3-6 months, check all screws and bolts to ensure they are tight. Retighten if necessary to maintain stability and safety.
- Gas Lift: The gas lift cylinder is maintenance-free. Do not attempt to disassemble it.
Troubleshooting
