Operating Instructions

Adjusting Seat Height

To adjust the seat height, locate the lever under the seat on the right side. While standing, pull the lever upwards to raise the seat. To lower the seat, sit on the chair and pull the lever upwards. Release the lever at your desired height. The seat height can be adjusted from 23.6" to 32.2".

Adjusting Foot Ring

The foot ring can be adjusted to provide comfortable support for your feet. Loosen the knob on the foot ring, slide it up or down the gas lift to your preferred position, and then tighten the knob securely.

Using the Backrest

The backrest provides lumbar support. It can be adjusted for height by loosening the knob at the back of the backrest support, sliding it up or down, and then re-tightening. The backrest can also be removed if you prefer to use the chair as a stool without back support.

Mobility and Swivel

The chair features 360-degree swivel and smooth-rolling casters for easy movement across various floor types, including carpet and hard floors. This allows for effortless repositioning and access to different areas of your workspace.

Maintenance

To maintain the appearance and longevity of your SUPERJARE Drafting Chair, follow these simple guidelines:

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners, which can damage the PVC seat material and chrome finish.
• Inspection: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
• Casters: Keep casters free of hair, dust, and debris to ensure smooth rolling.

Troubleshooting

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

• Chair does not adjust height: Ensure the gas lift lever is fully engaged. If the issue persists, the gas lift cylinder may need replacement.
• Chair wobbles: Check that all screws connecting the seat to the mechanism and the base legs are securely tightened. Ensure the chair is on a flat surface.
• Casters do not roll smoothly: Inspect casters for trapped debris (hair, lint) and clean them. Ensure they are properly inserted into the base.
