Operation

A-dec 500 Chair

How to Operate Your Chair The A-dec 500 dental chair is a hydraulically controlled dental chair providing a balance between patient comfort and doctor efficiency. The ease of operation and patient access was designed based on direct input from practicing dentists and hygienists.

Power On/Off Button The Power On/Off button is located on the base of the chair. This function allows you to engage power or disengage power to the entire system at the touch of a button. When the button is pressed in, the system has power. When the button is out, the system has no power (see Figure 1).

1 3

Chair Stop Plate The chair stop plate (see Figure 1) stops chair movement immediately when it is pressed. Should anything inadvertently become lodged under the chair, press Base Up on the footswitch or touchpad to raise the chair so the object can be removed. As long as pressure is applied to the stop plate, the chair will not move down.

Operation

A-dec 500 Chair

How to Position Your Chair The A-dec 500 chair can be operated manually or with programmed controls on an eight-function footswitch, a standard touchpad, or a deluxe touchpad. Using the arrows on the footswitch or touchpads, you can manually control the Back Up/Down (tilt) and the Base Up/Down (lift). Use the numbered buttons to assign programmed chair positions.

Manual Controls The Base Up/Down (lift) function controls chair lift, or vertical movement. To raise the chair, press the up arrow on the footswitch or touchpad and hold until the chair reaches the desired height. To lower the chair, press the down arrow and hold until the chair reaches the desired height.

Adjustments

A-dec 500 Chair

How to Adjust Your Chair The following detail talks about the components that you can use to adjust your chair.

Swivel Brake The chair 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 engage the brake, push the brake lever firmly to the left. To release the swivel brake, push the brake lever to the right.

1

2

Engaged If the chair swivels left or right with the brake engaged, or if it is difficult to move with the brake disengaged, adjust the swivel brake tension (see Figure 5). To adjust the tension, use a hex key and turn the tension adjustment screw clockwise to increase brake friction or counterclockwise to decrease brake friction.

Released

1 - Tension adjustment screw; 2 - Swivel brake handle Figure 5 Location of the Swivel Brake

Headrest The headrest provides adjustment features for easy access to the oral cavity and increased patient comfort.

3 4

Double Articulating The headrest adjustment lever allows the headrest to be adjusted using one hand. When the lever is released, the headrest holds its position. 5

Height Glide Bar The glide bar allows the headrest to accommodate a variety of patient heights (see Figure 6). To move the headrest higher or lower, simply pull up or push down on the headrest until it is at the desired height.

3 - Gliding headrest; 4 - Headrest lever; 5 - Glide bar Figure 6 Gliding Headrest and Glide Bar

NOTE: When the bar has reached its maximum recommended working height, a warning will be visible on the patient's side of the glide bar. Do not use the headrest if this warning is visible. Page 6

86.0602.00

A-dec 500 Chair

Adjustments

Glide Cushion The glide cushion adjusts to allow for minimal space between you and the patient, providing closer access to the oral cavity (see Figure 7). When the chair back is raised or lowered, the gliding headrest automatically follows the motion of the patient.

Figure 7 Operation of the Gliding Headrest

How to Position for Wheelchairs The headrest can be used to accommodate patients in locked wheelchairs. The table below describes how to position the headrest for wheelchairs. Table 4 Steps for Positioning Wheelchairs Step

Action

1

Slide the headrest glide bar up until it is free from the dental chair

2

Rotate it 180°, and slide it back into the backrest pushing it completely down (see Figure 8).

3

Position the dental chair to its full back up position.

Figure 8 Positioning for Wheelchair

Once the headrest is repositioned, adjust the height by moving the dental chair up or down. The patient should be positioned so the wheelchair and the dental chair are back to back.

86.0602.00

Page 7

Adjustments

A-dec 500 Chair

Drift Adjustment If the headrest drifts downward, or if it is difficult to move up or down, the glide bar tension needs to be adjusted. To adjust the tension, use a hex key and turn the tension adjustment screw clockwise to increase friction or counterclockwise to decrease friction (see Figure 9).

Figure 9

Adjustment of Headrest Drift

Armrest The armrests are designed to allow easy access for both you and the patient.

Upholstery

A-dec 500 Chair

How to Remove Upholstery The design of the upholstery makes removing and replacing it quick and easy. The upholstery on your chair is installed in three sections: back, seat, and headrest.

Back Upholstery To remove the back upholstery, firmly grasp the bottom edge of the cushion and lift upward (approximately 1-inch), then lift the upholstery out and away from the chair back. To reattach the back upholstery, place the key holes on the cution over the large fastener heads then push down until it snaps into position.

Figure 12 Removal of the Back Upholstery

Seat Upholstery To remove the seat upholstery, grasp the middle portion of the seat and lift firmly to unlock the upholstery. Then lift the toe of the seat to unhook it from the chair carriage, and move it away. To reattach the upholstery, place the two hooks on the back end of the seat upholstery under the chair carriage towards the head of the chair, and push the toeboard down until it locks into place.

Removing the Cover

4 7

The floor box cover lifts off with no tools for access to the utilities. To remove the cover, grasp the end of the cover and lift up and off.

Air and Water Manual Shutoff Valves Shutoff valves control the air and water to the unit. To prevent leaks, these valves should remain fully open (turned counterclockwise) except while your unit is being serviced.

Air-Actuated Air and Water Shut-Off Valves The air-actuated air and water shut-off valves automatically shut off air and water to the system when the master On/Off toggle is in the off position. This safety feature prevents water damage in the event of a water leak while the unit is unattended.
