FUNCTION
ADJUSTING HEADREST
To position the headrest, raise it completely to
release it, then move it to its lowest position. As
you slowly move it up, it will ratchet through
various stopping heights. Select the best height
for your comfort. To reposition, completely raise
and lower the headrest to reset it and start the
process again.
ADJUSTING SEAT DEPTH
To adjust the seat depth, lift
the lever under the left side
of the seat. Slide seat forward
or back and release lever to
lock it into position. Allow
2"-3"of space between the
back of your knees and the
edge of the seat.
ADJUSTING ARMRESTS
Lift the button under the arm to
adjust the height. Further, refine
your settings by grasping the top
of the arms and sliding in any
direction. For optimal ergonomic
positioning, elbows should stay
close to your sides and your
wrists should be straight.
SYNCHRO TILT
Rotate the left control knob to
lock and unlock the chair
recline. Lean back to the
desired position and turn the
same knob to lock the back into
one of four recline positions.
ADJUSTING SEAT HEIGHT
Height is adjusted using the
lever on the right-hand
control bar. Pull up on the
lever while lifting or lowering
your body weight in the chair;
the seat will adjust on its
pneumatic cylinder to reach
your desired height.
TILT TENSION CONTROL
Adjust the force needed to create a softer
or firmer recline motion. Pull out the lever
on the right-hand control bar and rotate it
several times. Turn clockwise for more
tension, counterclockwise for less tension.
