A-dec 500 Assistant's Instrumentation

How to Position Your Assistant's

Instrumentation

The A-dec 500 assistant's instrumentation is

equipped with either a short or long assistant's arm

for easy positioning of instrumentation. Both arms

are equipped with a touchpad and holder

assemblies with individual holders for added

positioning.

Short Assistant's Arm

The short assistant's arm positions near the

cuspidor or along side the chair back. It adjusts in a

forward, backward, and side-to-side movement for

easy positioning and access to the instrumentation.

Rotation of the Holder Assembly.

A pivot joint located close to the support link,

allows the entire arm to "tip-up," if forced, to

minimize damage to the equipment if lowered on

to an object.

The arm segment, attached to the touchpad, gives

way downward if forced beyond its normal range

of operation. Simply lift the arm back into place to

reset and continue operation.

Long Assistant's Arm

The long assistant's arm has the same features as

the short arm, and can be positioned closer to the

headrest. In addition, this arm accommodates

variable height adjustment for multiple users.

Holder Assembly

The holder assembly rotates completely for

positioning to suit most procedures (see Figure 5).

NOTE: If you have electric holders, the holder

assembly can be rotated 340 degrees only.

Adjustable Holders

The independently adjustable holders can be

pivoted 340 degrees to allow customized

positioning for each instrument on the holder

assembly.

To rotate each holder, pull holder slightly away

from the adjacent one, twist to the desired position

and release (see Figure 6).

Dual Holder Assemblies

The dual holder assemblies option gives the dental

team the ability to offset or alternate the syringe,

saliva ejector, and HVE placement. The additional

holder assembly helps the assistant to comfortably

differentiate and locate the instruments during the

dental procedure.

Electric Holders

The optional electric holders provide vacuum on/off switching for users whose vacuum system requires

this functionality. When the HVE or saliva ejector is lifted from the holder, the vacuum pump will

activate automatically. When placed back into the holder, the vacuum will be turned off.

Assistant's Touchpad

A standard touchpad serves as a convenient handle rotating 340 degrees for easy access and visibility.

The touchpad also provides a one touch surface for controlling the chair, dental light, and cuspidor/

A-dec relay module (a1, a2).

Left/Right Conversion

Positioning the assistant's instrumentation to the opposite side of the chair can be done in a minimal

amount of time. Loosen the support link locking screw located under the swivel brake handle, unsnap

the support link back cover, and reposition the arm to the opposite side. Once the instruments are in

place, reattach the support link cover, and tighten the support link locking screw finger tight.
