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.
