The tilt tension adjustment balances your weight so the chair can be
tilted with ease. The ideal tilt tension lets you lean back in your chair
with minimum effort, but with enough resistance to provide back
support at any position throughout the tilt range. Normally, this
adjustment is performed once. To increase or decrease tension turn
the knob located on the underside of the chair, clockwise or
counter-clockwise.
To raise the backrest simple grasp
the back from either top, bottom or
sides and lift upward slowly. Listen
for the distinctive "click" as the
backrest auto-locks as it moves
upward every ½". To lower the
backrest, simply raise the back to
maximum height and allow the
backrest to fall to its lowest position.
The back height adjustment allows you to raise and lower the
backrest relative the seat. The backrest should be positioned
so that the small of your back is comfortably supported by the
backrests contoured lumbar.
4. Adjust Back Angle
To adjust the backrest angle pull up
on the lever labeled and lean
forward or backward until you have
found a comfortable position.
Release the lever and the backrest
will lock in your preferred position.
The backrest angle adjustment allows you to position the
backrest angle relative to the seat. The backrest should
be adjusted so that the angle between your torso and
thighs is greater than 90º and provides firm support
during your varied daily tasks. Maintaining constant
contact with the backrest at all time will maximize your
overall comfort and will reduce muscle fatigue, (sit back
deep in your chair).
