CONTENTS
Your Cascade chair is an electronically controlled,
hydraulically powered dental chair (see Figure 1).
Chair functions are controlled by the 8-function
footswitch or touch pad (see Figure 2 or 2a on
page 3).
The chair LED indicates the status of the chair:
ON: Normal operation.
SLOW BLINK: The cuspidor or stop plate limit
switches have been activated. Remove any obstructing
object.
The chair stop plate (see Figure 1) stops the chair
immediately when any part of it is pressed. Should
anything inadvertently become lodged under the chair,
press Base UP on the footswitch or touch pad to raise
the chair so the object can be removed. As long as
pressure is applied to the stop plate, the chair base will
not go down any further.

audible tone will be emitted. Then, within four
seconds, push the button for 1or 2 to store that
position. You will hear an audible tone confirming that
the programmable function has been reprogrammed.

lowers the chair back to its previous operating position.
Position 3 may also be used as a third Pre-Position or
as a last recall.
Contact an authorized A-dec Dealer to have Position 3
reconfigured to a third Pre-Position or as a last position
recall.

moving the chair to another position. Push the Entry/
Exit (0) button. The chair should move automatically to
the position you set in Step 1.
7
Cascade 1040 Chair
NOTE
When pushed, Entry/ Exit (0) will cause the
chair base and back to go to the preset
entry/exit position.
To stop the chair at any point, push any
button on the footswitch or touch pad.
When engaged, the chair swivel brake restricts
rotation of the chair. With the brake released, you can
rotate the chair to any position within approximately
30° either side of center. To unlock the swivel brake,
push the brake lever to the right. To lock the swivel
brake, push the brake lever to the left.
If the chair swivels left or right with the brake
engaged, or if it is difficult to move with the brake
disengaged, the swivel brake tension must be adjusted.
Using a 3⁄16-inch hex key, adjust the swivel brake
tension. Turn the adjusting screw clockwise to increase
brake friction. Turn the screw counterclockwise to
decrease brake friction.

If the headrest drifts downward, or if it is difficult to
move up or down, the glide bar tension must be
adjusted. Remove the headrest glide bar to access the
adjusting screw.
Using a Phillips screwdriver, adjust the glide bar
tension. Turn the adjusting screw clockwise three to four
revolutions to increase friction and hold the headrest
more securely. Turn the screw counterclockwise three to
four revolutions to decrease friction and allow the
headrest to move up and down more freely. Reinstall
the headrest and recheck glide bar tension.

A-dec’s unique formed upholstery makes replacing
upholstery quick and easy.
The upholstery on your Cascade 1040 Chair is
installed in four sections: back, headrest, seat, and
armrests. Each section is easily removed and replaced.
To remove back upholstery firmly grasp the bottom
edge of the cushion and lift upward, approximately
1-inch, to release the four large, flat-headed fasteners
from the cushion key-slots.
To install back upholstery place the large fastener
heads in the cushion keyhole pockets then push in and
down in one motion.
