5. Operating Instructions
The Safco Uber chair offers several adjustments to optimize your comfort and support:
- Height Adjustment: Use the pneumatic lever located under the seat to adjust the chair's height. To raise the seat, lift the lever while taking your weight off the seat. To lower the seat, lift the lever while seated. The height can be adjusted from 19.5" to 23.5".
- Tilt Adjustment: The backrest features a tilt adjust mechanism with tilt tension and lock. Locate the tilt control knob or lever under the seat. Adjust the tension to control the ease of recline, and use the lock feature to secure the backrest in a desired position.
- Swivel Function: The chair is equipped with a 360-degree swivel seat, allowing for easy rotation and access to different areas of your workspace without needing to move the entire chair.
6. Maintenance
Proper care and maintenance will extend the life of your Safco Uber chair:
- Cleaning: For the black vinyl upholstery, wipe with a damp cloth and mild soap. Avoid harsh chemicals or abrasive cleaners, which can damage the material. Refer to the product care instructions for specific details.
- Hardware Check: Periodically inspect all screws, bolts, and connections to ensure they are tight. Re-tighten as necessary to maintain stability and safety.
- Caster Care: Keep casters free of debris such as hair or lint to ensure smooth movement. Clean them regularly.
- Pneumatic Cylinder: While designed for durability, avoid excessive force or impact on the pneumatic cylinder. If the chair's height adjustment becomes inconsistent, contact customer support.
