Operating Instructions

Your Razzor Ergonomic Office Chair offers several adjustable features to customize your comfort.

Height Adjustment

To adjust the seat height, pull the lever located under the right side of the seat upwards while applying or releasing weight from the seat. The pneumatic seat-height adjustment allows for a range of 16.6" to 20.5".

Tilt Function and Tension

To recline the backrest, pull out the lever located under the left side of the seat. The chair supports a tilt range of 90° to 135°. To adjust the tension of the tilt, rotate the tension knob located under the front of the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).

Adjustable Headrest

The headrest can be adjusted in height by 4.3 inches and rotated by 30° to provide flexible neck support and help prevent cervical spondylosis.

Maintenance

To ensure the longevity and optimal performance of your Razzor Ergonomic Office Chair, follow these simple maintenance guidelines:

• Cleaning: Wipe clean with a damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the mesh or frame.

• Weight Limit: Adhere strictly to the maximum weight capacity of 300 LB to prevent structural damage.

Troubleshooting

This section addresses common issues you might encounter with your Razzor Ergonomic Office Chair.

Chair is unstable or wobbly:

• Check all assembly screws, especially those connecting the backrest, seat, and mechanism to the base. Tighten any loose screws.
• Ensure the gas lift is properly seated in the base and mechanism.

Height adjustment not working:

Chair does not recline or tilt:
