Operating Instructions

Your HERCULES Series chair offers multiple adjustment features to customize your seating experience for optimal comfort and ergonomic support.

1. Seat Height Adjustment:

To raise the seat, lift the pneumatic seat height adjustment lever (typically on the right side, under the seat) while taking your weight off the seat. To lower the seat, lift the same lever while seated. Adjust until your feet are flat on the floor and your knees are at a 90-degree angle.

2. Synchro Tilt Control:

The 2-to-1 synchro tilt control allows the chair's back and seat to recline at different rates, increasing the angle between your torso and thighs for added comfort. Use the lever on the left side (when seated) to engage or disengage the tilt. Adjust the tension knob (usually a large round knob under the front of the seat) to control the resistance of the tilt.

3. Seat Depth Adjustment:

To adjust the seat depth, locate the paddle control (often near the front-left under the seat). Lift the paddle and slide the seat forward or backward to accommodate the length of your thighs. This ensures your back remains in contact with the backrest while avoiding pressure behind your knees.

4. Armrest Adjustment:

The armrests are height adjustable. Press the button on the side of the armrest support and slide the armrest up or down to your desired height. The arm pads also pivot inward and outward for greater customization, providing optimal support for your arms and shoulders.

5. Lumbar Support Adjustment:

The adjustable lumbar support is located on the backrest. You can slide it up or down to position it correctly for your lower back curve, providing targeted support and minimizing back strain.

6. Swivel Function:

The chair features a 360-degree swivel seat, allowing for easy movement and access to different areas of your workspace without needing to reposition the entire chair.

Maintenance

Regular maintenance will help preserve the appearance and functionality of your office chair.

Cleaning Instructions:

• For general cleaning of the fabric and mesh, use a damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Wipe down the chrome base and plastic components with a soft, damp cloth.
• For stubborn stains on fabric, a mild soap solution can be used, but always test on an inconspicuous area first.

General Care:

• Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary.
• Keep the casters clean from debris (hair, dust, etc.) to ensure smooth rolling.
• Avoid exposing the chair to direct sunlight or extreme temperatures for prolonged periods, as this can cause material degradation.
