EXECUTIVE HI-BACK CHAIR
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 rise 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.
2. To Operate Tilt Lockout:
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.
4. Adjustable Arms:
This chair has an adjustable arm function so the
arms can be pushed up or pulled down. The arms
can be pushed up next to the back cushion so the
chair can easily roll under a desk.
