Operate / Adjust
Dual-Articulating Headrest
The dual-articulating headrest includes several adjustment features that
improve your access to the oral cavity and increase patient comfort.
Use the glide bar to accommodate a variety of patient heights. Simply
pull up or push down on the headrest until it is in the desired position.
The gliding headrest cushion provides additional height adjustment.
WARNING If the glide bar has exceeded its maximum
recommended working height, a warning line will be visible
on the patient’s side of the glide bar. Do not use the headrest
in a position where this warning line is visible.
Glide Bar
Locking Knob
The locking knob allows you to easily adjust the headrest for a full
range of positions. Release the headrest by turning the locking knob
counterclockwise, then adjust the headrest for a proper fit. Lock the
headrest in the desired position by turning the knob clockwise.
Headrest Glide Bar Tension
If the headrest drifts downward, or if it is difficult to move up or down,
the glide bar tension needs adjustment.
To adjust the tension, use a 1/8'' hex key. Turn the tension adjustment
screw clockwise to increase friction or counterclockwise to decrease
1/8" Hex Key
Headrest Position for Wheelchairs
To position the headrest for wheelchairs:
1. Remove the headrest from the dental chair.
2. Rotate the headrest 180° and slide the glide bar into the backrest
until it stops.
3. Swivel the dental chair, if necessary, and position the backrest to its
full upright position.
4. Position the wheelchair and the dental chair back to back.
5. Move the dental chair up or down, as needed, to adjust the headrest
6. Lock the wheelchair wheels.
Patient Positioning
To properly seat patients in the chair, ask the patient to sit as far back
in the seat pocket as possible. This ensures the best alignment with the
lumbar support and headrest.
For optimal comfort, patients should place their forearms on the
armrests or keep their arms comfortably folded on their lap.
WARNING Do not allow patients to drop their arms behind
the armrests or under the backrest during chair movement.

Two-Position Armrests
You can move the armrests out of the way to allow for easy patient
entry/exit and to improve operator access when working direct. Push or
pull to reposition the armrests in the forward or back position.
Armrest Rotation Tension
If the armrests become loose or are difficult to move, you can adjust the
rotation tension. To adjust each armrest:
Hex Key
1. Remove the chair side cover by pulling on the left and lower right
sides of the cover. Pull the cover out of the way to access the adjustment screw.
2. Use a 5/32" hex key and turn clockwise to tighten or counterclockwise to loosen the armrest tension. Only a small adjustment is
needed to significantly increase or decrease tension.
Chair Swivel Brake
Chairs that swivel can rotate to any position within 30° either side of
center. The chair swivel brake restricts rotation of the chair to keep the
chair from moving during a procedure.
To release the swivel brake, pull the brake lever to the right. To engage
the brake, pull the brake lever firmly to the left.
Chair Swivel Brake Tension
If the chair swivels left or right with the brake engaged, or is difficult
to move with the brake disengaged, adjust the swivel brake tension.
Properly tensioned, the brake handle should be in the middle when it is
fully engaged. To make the adjustment:
1. Move the brake handle to the right.
2. If the chair includes a back mount module, swivel the chair to access
the adjustment screw.
3. Use a 7/64" hex key and turn the tension adjustment screw clockwise to increase brake friction or counterclockwise to decrease brake
friction. Only a small adjustment is needed to significantly increase
or decrease tension.

Barrier Protection
A-dec recommends barrier protection for all applicable touch and
transfer surfaces. Touch surfaces are areas that come into contact with
hands and become potential cross-contamination points during dental
procedures. Transfer surfaces are areas that come into contact with
instruments and other inanimate objects.
In the USA, barriers must be produced under the Current Good
Manufacturing Practice (CGMP) as specified by the U.S. Food and Drug
Administration (USFDA). For regions outside the USA, refer to the
medical device regulations specific to your location.
NOTE For proper use and disposal of barriers, see the
instructions provided by the barrier manufacturer.
IMPORTANT For recommendations on cleaning and
chemical disinfection of touch and transfer surfaces (where
barrier protection is not applicable or when barriers are
compromised), please see the A-dec Equipment Asepsis Guide
(p/n 85.0696.00).
CAUTION Do not use household bleach (sodium
hypochlorite) or other products containing chlorine,
isopropyl alcohol (greater than 25 percent by
volume), or hydrogen peroxide to clean or disinfect
the upholstery. It can cause rapid deterioration and
damage the product.
To preserve the quality of your A-dec upholstery, use barrier covers
instead of relying on chemicals. Barriers significantly extend the life of
the upholstery and will help to preserve its luxurious look and soft feel.
To clean the upholstery, use a solution of mild detergent and water. Use
surface disinfectants only when the barriers have been compromised or
there is visible spatter on the upholstery. See the A-dec Equipment Asepsis
Guide for more information.
The utilities for A-dec chair-mounted delivery systems are located
in the contoured floor box under your chair. To maintain these
utilities, see your system Instructions for Use. If you have a chair-only
configuration, you may still have a floor box that hides the power cord
and outlet. For access, lift the cover up and off the floor box frame.
CAUTION When removing or replacing covers, take care not
to damage any wiring or tubing. Verify that the covers are
secure after replacing them.
