1. To Adjust Seat Height:
While seated, lean forward and reach under the
right side of the chair to find the handle. Lift the
handle and raise your body up slightly to allow
the chair to raise to the desired height. To lower
the seat, lift the handle while applying more
weight downward on the seat. The chair will
descend until the handle is released or the chair
reaches the bottom position.

While seated, reach under the left side of the
chair to find the lockout bar. Slide the bar to the
left (or to the outside), all the way out allows the
chair to tilt backwards. To lock the chair in the
vertical position, sit upright and push the bar to
the right (or the center of the chair).
3. To Adjust Tension on The Tilt
Mechanism:
Reach under the front center of the chair, grasp
the round knob and turn counter - clockwise to
make the tilt mechanism firmer (stiffer). To loosen
the tilt mechanism, turn the knob clockwise until
the desired resistance is felt.
