2.1. Unpacking
2.1.1. Open the shipping carton carefully and record
any shipping damage to the carton or to the contents.
2.1.2. Remove the upper portion of the crate from the
skid and unbolt the base clamping boards. lt is recom-
mended that the crate be located adjacent to the spot
where it is to reside before unpacking the upper struc-
ture. This is so that the chair can slide olf of the skid and
right into place. Do not litt the chair by the upper struc-
ture, although the chair may be tipped or slid by pushing
or pulling the upper structure.
2.1.3. For shipping purposes, the chair back has been
tilted Jorward and tied. Remove the string. To secu re the
chair back in the proper upright position, locate the seat
supporl casting underneath and to the rear of the chair
back. From either side, remove the E-clip retaining ring
and spacer. Pull the pin out. Pull the chair back to the
upright position and align the gas spring clevis wlth the
center of the seat suppon casting. Replace the pin and
spacer. Reattach E-clip.

2.1.4. Asmalltool packel containing tour hexagon allen
wrenches, sizes 1/8, 3116, 3132, and 5/64, has been
included in the shipping carton.
2.2. Assembly L,
Remove allwrappings. Onlythe headrest has been
removed lor shipment.
2.2.1. Chair Cushions
The cushions on the back and seat of the chair are
identical. To vary stress points/wear patterns on the
upholstery, it may be desirable to periodically reverse
the cushions (back to seat, seat to back).
2.2.1. Mounting the Headrest
Remove the back cushion assembly by pulling
straight out from the chair. The seat cushions are both
attached with velcro strips. This will permjt access to the
seat-back. Slide the pivot bracket on the headrest into
the slot in the top of the back cover (Figure 1), and into
the bracket mounted under the chair back cover. lf the
pivot bracke't does nol drop in smoothly, the mounting
screw (slightly o{f-center in the chair back) may need to
be backed out 10 allow the bracket to fit. This screw is a
socket head set screw which requires a 1/8 hexagon key
allen wrench (included in the tool packet shipped with Y/
the chair) to loosen. When the bracket has been in-
stalled, tighten the screw until it is snug. Replace the
back cushion.

a Reliance@ instrument stand, the chair con-
trol cable supplied will provide proper opera-
tion. Refer to the instrument stand manualfor

FIGURE
3. OPERATION
CAUTION: Caution should be taken to observe that
there are no obstructions (instruments, trays, or
tables) to impede the movement of the chair.
3.1 . Chair Lift
3.1.1. Raising and Lowering the Chair
Alootswitch is used to raise and lowerthe Reliance@
Model 5200 chair (Figure 3). Depress the right side of the
footswitch to raise and the left side to lower.
NOTE: When operating the footswitch, the motion of
the chair will STOP when the switch is released.
tN - 5200
lf this chair is used in conjunction with a Reliance@
instrument stand that has chair control capabilities, the
chair may also be raised or lowered via that instrument
stand.
NOTE: Rejer to the instrument stand manual for in-
structions.
3.1 .2. Revolving
The chair upper structure may be revolved 360'.
The lock which inhibits or allows chair movement is
controlled by a hand lever which is easily identified by a
chrome-plated knob. This lever is located below the
seat, centered irom lront to back. Though there is a lever
on either side oJ the chair, they do not function indepen-
dently (Figure 1). This allows access from e jther side ol
the chair. Push the lever down to release the lock. Lift to
apply the lock.
3.2. Repositioning the Chair Back
The chair back may be reclined or raised by either
pushing downward or pulling upward on lhe release
lever (Figure 1 ). While the back of the chair will recline to
a horizontal position, the foot rest will always remain
stationary.

3.3. Arm Movements
The chair arms may be moved to provide better
accessto the palient, orto permil entrance to or exit f rom
the chair. The movements of both arms are identical and
completely independent of each other.
3,3.1. Articulating Arm
To raise an arm simply lift upward. A stop limits
upward motion ol the arm to a point parallel to the plane
of the back (Figure 4). At its lowest position, the arm will
always be parallel to the floor or horizontal (Figure 1).
There is no lock in either the upper or lower position.
Both arms will articulate when lhe chair is reclined.
In other words, the arms will remain in a horizontal
position regardless of how far back the chair is reclined.
3.4. Headrests
The No. 11 headresl is the standard headrest for
the Model5200 chair. Headrest No. 18 is also available.
3.4.1. Operation - No. 11
A single handle on the rear of lhe No. 11 headrest
controls the locking mechanism. To unlock, grasp lhe
handte and turn counter-clockwise. Change the tilt of the
headrest until it is in the desired position. To lock, turn the
handle clock-wise until snug.
3.4.2. Adiustment - No. 1 1
The handle on the outermost knob can be adjusted
to any preferred, locked position. Simply push in on the
large screw while pulling out on the handle. Rotale as
desired, and release (Figure 5).

FIGURE 5
3.4.3. Operation - No. 18
The No. 18 headrest is designed so it can be
operated with just one hand. To unlock, squeeze clear
plastic actuator into lock housing. This will allow both
pivots of the articulating arm to rotate so the headrest
can be moved to a new desired position. Once inthe new
position, release the actuator. l\4ake sure the actuator
expands to its original position to insure a positive lock.
The headrest pad is free to rotate at all times.
3.4.4. Adjustment - No. 18
There are th ree adjustments provided on the No. 1 I
headrest. The firsi is the tension on the pad rotation. By
tightening the two hex acorn nuts on the pad pivots with
a 3/8" open end wrench, the tension will be increased. To
adjust the drag on the pivots of the articulating arm,
loosen the set screw in the center of the pivot with a
3/32" hexagon key wrench (Figure 6, item 1). Next,
tighten the pivot screw on the other side of the pivot, with
a 1i8" hexagon keywrench. Now, retighten the set screw
to retain the pivot screw at the new adjustment. Either
pivol may be adjusled.
The third adjustmenl is ior the spring plunger at the
rear of the lock housing (Figure 6, item 2). lf the plastic
actuator does not readily return lo its original position
assuring a positive lock, the spring plunger requires
adjustment inward (clockwise). lf a clicking, dragging
noise is apparent when the actuator is fully depressed
and the headresl is moved, the spring plunger requires
adjustment outward (counter-clockwise).
3.5. Chair Back Cover Removal (for servicing unit)
3.5.1. Remove the front of the seat-cushion assembly
by pulling straight oul from the chair. The seat cushions
are both attached with velcro strips. This will permit
access to the seat-back.
