4. Attach the Base Plate to the Seat Cushion:

   Fix the Base Plate (7) to the bottom of the Seat Cushion (2). Tighten the 4 M6x18mm screws (9) with the Hexagon Wrench (12) firmly. Ensure the 'FRONT' sticker on the seat cushion aligns with the front of the base plate.

5. Attach the Backrest to the Seat Cushion:

   Fix the Backrest (1) to the back of the Seat Cushion (2). Tighten the 3 M6x25mm screws (10) with 3 Gaskets (11) using the Hexagon Wrench (12) firmly. Ensure the 'FRONT' sticker on the seat cushion is facing forward.

6. Connect the Seat Assembly to the Base:

   Insert the Air Rod (6) into the hole in the middle of the Base Plate (7). Press the Seat Cushion (2) from top to bottom, using your whole body's weight to insert it firmly. The assembly is now complete.

   Caution: If the Air Rod (6) doesn't insert firmly into the Base Plate (7), the chair is likely to fall off when it rises up.

Operating Instructions

Height Adjustment

To adjust the chair's height, locate the pneumatic adjustment lever beneath the seat. Lift the lever up to raise the chair. To lower the chair, lift the lever while seated. The chair's height can be adjusted from approximately 22 inches to 30 inches, suitable for various desk heights, including standing desks.

Foot Ring Adjustment

The footring can be adjusted to provide optimal leg support. Loosen the knob on the footring, slide it to your desired height, and then tighten the knob firmly to secure it in place. This allows for a balanced angle between your thighs and the seat, relieving discomfort during prolonged sitting.

360-Degree Swivel

The chair is designed with a 360-degree swivel function, allowing for easy movement and access to your workspace without strain.

Ergonomic Backrest

The C-shaped mesh backrest is designed to fit the curve of your lower back, promoting better posture and reducing stress and muscle fatigue.

Maintenance

To maintain your Primy PR777-Z chair, follow these guidelines:

• Cleaning: Spot clean the fabric and mesh components as needed. Use a mild detergent and a damp cloth. Avoid harsh chemicals that may damage the material.
• Inspection: Periodically check all screws and connections to ensure they remain tight. Re-tighten if necessary.
• Casters: Keep the casters free of debris (hair, dust) 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 pneumatic lever is fully engaged. If the chair still does not adjust, check if the air rod is properly seated in the base plate (refer to assembly step 6).
• Chair wobbles: Verify that all screws connecting the base tubes and the seat components are securely tightened. Ensure the casters are fully inserted.
• Casters not rolling smoothly: Check for any debris (hair, lint) caught in the caster wheels and remove them.

For persistent issues not covered here, please contact Primy customer service.
