Operating Instructions

Chair Adjustments:

• Height Adjustment: Use the lever located under the right side of the seat to raise or lower the chair to your desired height. Pull the lever up while seated to lower, or pull up while standing to raise.
• Backrest Recline (90° to 150°): The backrest can be reclined from 90 degrees (upright) to 150 degrees (nearly flat). Use the lever on the left side of the seat to adjust the recline angle. Release the lever to lock the backrest in position.
• Retractable Footrest: Pull the footrest out from under the seat when you wish to extend your legs. Push it back in when not in use.
• Adjustable Armrests: The armrests are height-adjustable. Locate the button or lever on the side of each armrest to adjust their height.

Maintenance

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that may damage the PU leather.
• Regular Checks: Periodically inspect all screws and bolts to ensure they are tight. Re-tighten as necessary to maintain stability and safety.
• Caster Care: Keep casters free of hair and debris to ensure smooth movement.
• Leather Care: For best results, condition the PU leather periodically with a suitable leather conditioner to prevent drying and cracking.

Troubleshooting

• Chair Sinks or Does Not Adjust Height: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift may need replacement.
• Chair Does Not Recline: Check that the recline lever is properly engaged and not obstructed.
• Squeaking Noises: Tighten all screws and bolts. Applying a small amount of lubricant to moving parts (e.g., gas lift, recline mechanism) may also help.
• Stiff Caster Movement: Clean any debris from the casters. Consider replacing casters if they remain stiff or damaged.
