2 Installation,OperationandCareManual 
Section I Introduction
This manual contains installation, operation and care
instructions and user service information for the
Simplicity®Cart Delivery Unit.
The Simplicity Cart is available in two standard con-
gurations: (1) Duo (doctor's and assistant's) instru-
mentation and (2) doctor's only instrumentation.
The Simplicity Cart Delivery Unit is intended to be
used by trained professional dental care personnel
as an interface device to connect the dental oper-
atory hand instruments to the appropriate supply
utility such as air, water, vacuum, drain and electrical.
It functions as a system management device that
provides a method of operating the hand instruments
from a single control input device.
The Simplicity cart, situated on wheels, positions
the handpieces for the optimum presentation to the
operator.
The Unit is designed to provide trouble-free service
when installed, operated and maintained according to
the procedures set forth in this manual.
To ensure correct installation, carefully read all
the procedure instructions contained in this
manual paying close attention to all notices,
notes, cautions and warnings.
Before proceeding, please review the photo below to
become familiar with the basic components of the Unit.
After the Simplicity Cart is installed, please review
the operation procedures and care guidelines with the
doctor's staff. Then leave this manual in the doc-
tor's ofce for future reference.

Section V Operation
Instrument Hanger
•An automatic CUT OFF, can be demonstrated
by placing tubing in the hanger and disabling
operation for that position.
Some of the Simplicity Cart Delivery Unit design
features:
•Operation of three handpieces and a syringe.
•Drive air may be adjusted individually for each
handpiece.
•
An automatic cut-off valve in each handpiece
holder section disables operation for that position.
• Foot control toggle valve allows wet or dry cutting.
•Master switch turns entire unit ON and OFF.

Master Switch
Oil Collector/
Filter Cover
Screws
• Each handpiece holder angle can be adjusted by
using an Allen wrench to loosen two set screws
in the back of each section and rotating it to the
desired angle; then re-tightening the screws.
• An oil collector/lter is designed to collect oil
from the handpiece exhaust air. Once a week,
check the lter for cleaning or replacement by
removing the two screws that secure the lter
cover.

Section V Operation
Handpiece
Coolant Water Adjustment
•Coolant water spray to all the handpieces can
be turned ON or OFF using the toggle switch
located on the foot control.
• The coolant spray volume is regulated for each
handpiece by using the coolant water adjustment
valve located on the side of the delivery head.
• While operating a handpiece, turn the coolant
water adjustment valve counterclockwise (while
looking directly into valve) to increase the volume of
coolant water spray. To decrease volume, turn
the valve clockwise.
Air Pressure
Air pressure to each handpiece can be adjusted to
the manufacturer's specications by following the air
pressure instructions in Section IV Testing under the
heading Air Pressure on Page 11.
NOTE: These procedures must be done while:
•The master switch is in the ON position,
•The handpiece is out of its holder and
•The foot control is fully depressed.
NOTE: When making necessary air pressure
adjustments, refer to the air pressure gauge located at the side
of the cart to check the approximate amount of air pressure
delivered to the handpiece.

as described above.
The speed of the handpiece is controlled by depressing the disc
located on the foot control.
• A light pressure on the foot control disc causes a
slow speed.
Fiber Optics (Optional)
If the handpiece utilizes coolant air, the chipblower
feature is used to blow debris away from the cutting
site by creating an air blast through the handpiece
without causing the burr to rotate. To operate the
chipblower, depress and hold down the valve button
on the upper right of the foot control.
The syringe is designed to deliver air or water, or a
mixture of air and water, as required.
•To deliver water only, press the button on the
syringe marked with a water drop symbol.
• For air only, press the button on the syringe with
no marking.
• To get a spray mixture of air and water, press
both buttons simultaneously.
The ber optics control is automatically activated by
operating the handpiece using the foot control.
NOTE: When the foot control is released, the ber optics
light will stay on for approximately ten seconds to allow
inspection of the cutting site.

Section VI Care
Cleaning Disinfecting
The Simplicity Cart Delivery Unit should be cleaned
as follows:
•Wipe frequently with a damp, lint-free cloth.
• Use a mild detergent to clean stains.
• At the end of the day, ip the master switch to
the OFF position and clean the instrumentation.
• Each morning, ip the master switch to the ON
position and check the air and water system for
proper operation using the three-way syringe.
Liquid disinfectants are recommended for use on all
external surfaces and should be applied using a soft,
clean cloth.
Use extreme caution when selecting the proper
chemical disinfectant for the delivery unit.
NOTE: *Cavicide™is the recommended disinfectant for
use on all external surfaces.
