Important Safety Information

Energy Accumulators

⚠️ Warning: Only trained personnel may replace or repair seat height adjustment components with energy accumulators.

Safety Castors

The safety castors on this chair are designed to brake automatically when no one is sitting in the chair. This prevents the chair from rolling away unexpectedly when you stand up, ensuring it remains in the position where you left it.

Chair Adjustment and Usage

ℹ️ Information:

Tilt Function

The chair features a tilt mechanism. The lever under the seat controls the tilt lock and free-float function. [Unlocked symbol ?] indicates free tilt, allowing the chair to recline. [Locked symbol ?] indicates locked tilt, keeping the chair in an upright position.

Seat Height and Tilt Tension Adjustment

Seat Height: Use the lever under the seat to adjust the seat height. Lift the lever to raise the seat, and sit down to lower it.

Tilt Tension: The knob located under the seat controls the tilt tension. Turn the knob clockwise ➡️ to increase resistance (making it harder to tilt) and counter-clockwise ↩️ to decrease resistance (making it easier to tilt).

Visual Description: Diagrams illustrate the tilt mechanism, seat height adjustment, and tilt tension adjustment knob. A weight symbol ➕ indicates increased tension/tilt, and ➖ indicates decreased tension/tilt.
