5. Operating Instructions
- Height Adjustment: To raise the chair, lift the lever on the right side of the seat while standing. To lower, lift the lever while seated. Release the lever at the desired height.
- Recline Adjustment: Pull the recline lever on the right side of the chair (below the seat) to adjust the backrest angle. Release the lever to lock the backrest in place.
- Tilt Lock/Unlock: The lever on the left side of the seat controls the tilt function. Push it in to lock the chair in an upright position, or pull it out to allow the chair to tilt.
- Tilt Tension Adjustment: Rotate the knob located underneath the seat, at the front of the mechanism, to adjust the tension of the tilt mechanism. Turn clockwise to increase tension (harder to tilt), counter-clockwise to decrease tension (easier to tilt).
- Armrest Adjustment: The armrests can be adjusted vertically by pressing the button on the side of each armrest and moving them up or down.
6. Maintenance
- Cleaning: For fabric surfaces, use a soft cloth dampened with mild soap and water. For PU leather, wipe with a damp cloth and dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all bolts and screws to ensure they are tight. Retighten if necessary.
- Caster Care: Clean casters regularly to remove dust and debris that may hinder smooth movement.
- Gas Lift: Do not attempt to disassemble the gas lift cylinder. It is a sealed unit.
