1.5Contra-indications
Welch Allyn Kreativ Air Abrasion products are designed for use by and on the order of a dentist. Furthermore,
Welch Allyn Kreativ products are not intended to be used outside the device’s specifications or limitations. Results
are not guaranteed or warranted if other than approved (Welch Allyn Kreativ) disposable products are used.
1.6Environmental Considerations
Prior to the installation of the Mach 6.0 air abrasion unit, it will be necessary to provide utilities and create an
environment suitable for the trouble-free operation of the equipment.
1.6.1POWER
All components operate on 100 - 240 VAC 50/60 Hz, single phase power. The use of surge protectors is recommended
when possible.
1.6.2AIR
The Mach 6.0 air abrasion unit requires input air pressure at a minimum of 80 PSI and a maximum of 130 PSI. Air
pressure can be delivered to the Mach 6.0 via a main office air compressor, a compact portable compressor, or
compressed nitrogen.
1.6.3Main Office Compressor
The main office compressor should be sized to deliver 80-130 PSI of constant, clean air pressure to the Mach 6.0 unit.
The Mach 6.0 unit is equipped with an internal Coalescing Filter which ensures a clean and dry air supply stream.
Under extreme environmental humid conditions an additional dryer is recommended to be installed on the air line
between the compressor and Operatory Regulator. This will ensure extra protection to the Mach 6.0 unit. If the
Operatory does not have the minimum air input requirement, the Mach 6.0 will not perform to the desired specification
level and the customer should be informed that auxiliary air supply may be required.
1.6.4Compressed Nitrogen
Compressed nitrogen can be used to supply the air pressure for the Mach 6.0 unit. There are variously sized tanks
available from most local gas companies. The regulator on the nitrogen tank should not exceed 130 PSI.

2.Theory of Operation
2.1Introduction
The Mach 6.0 is an air abrasion system. An external air supply is required to mix abrasive powder and air in a
pressurized chamber, which then moves through the nozzle tip of the handpiece. The Front panel control provides a
means of adjusting the required air pressure and powder flow.
2.2Functional Description
When the unit is initially turned on, the microprocessor resets all solenoids. The Particle energy indicators flash while
the STAND-BY, ON, LOW, MEDIUM, AND HIGH indicators cycle one time, in that order. When the indicators stop
flashing or cycling, the unit is ready to operate. The last settings used will be displayed. The yellow Standby
indicator will be turned on.
When the Ready Mode is selected, the system timer is set for ten (10) minutes. The Feed solenoid (SV-6) energizes
closing the canister top valve, the Canister solenoid (SV-4) energizes and the Master solenoid (SV-5) opens flushing
the filter at the top and the orifice plate at the bottom of the powder canister. After 5 seconds the Canister solenoid
(SV-4) closes, the system is pressurized. The Air On LED lights, Air Standby light extinguishes, and the system is
ready.
If the hand piece was not in the cradle on power up, and the Footswitch is depressed, the Standby lamp will flash for
½ second indicating the hand piece must be placed in the cradle momentarily. The unit will remain in the “ON” state.
If the hand piece has been in the cradle and is removed, when the foot switch is depressed, the pinch valve is opened
by Pinch Valve Solenoid (SV-1). This opens the path for powder flow from the mixing chamber to the nozzle.
When the hand piece is returned to the cradle or if the system is placed into Standby, the Pinch Valve solenoid (SV-
1) closes off the pinch tube and the foot switch is disabled Feed solenoid (SV-6) opens the valve to the top of the
canister to relieve system pressure. When the foot switch is released, the Exhaust Purge solenoid (SV-3) opens an
exhaust path to stop powder flow. The Master solenoid (SV-5) closes.
The Low, Medium or High Beam Intensity selection can be adjusted to provide optimum powder flow.
Stand-by mode may be selected by a) depressing the Stand-by / On button, or b) inserting the hand piece into the
cradle, the unit de-pressurizes. Power can then be cycled to off. After 10 minutes of non-use the unit will
automatically go to stand-by.
Safety features built into the Mach 6 unit are:
• Depressurizing when the hand piece is placed into the holder. This prevents accidental discharge of the powder
if the foot switch is depressed.
The instrument should only be powered down with the unit in the Standby Mode.
Please refer to Section 3 for preventive maintenance requirements that will keep the instrument operational.
WARNING: Do not open the top lid of the unit with power turned on!

3.ROUTINE MAINTENANCE
3.1Routine Maintenance of the Mach 6.0
Welch Allyn Kreativ Air Abrasion systems have been designed to operate with a minimum of operator attention.
Like all mechanical systems, they will operate longer and with less trouble when operator maintenance is performed
regularly. Maintenance on a Welch Allyn Kreativ Air Abrasion system is limited to cleaning, infrequent lubrication,
pinch tube replacement, and filter cartridge replacement. The maintenance procedures have been categorized by their
frequency of action and are described in this chapter with specific instructions.
3.2Daily Requirements
3.2.1Powder Canister
Observe the powder level in the Powder Canister, and inspect for moisture contamination. If moisture contamination
is present, the powder will not flow evenly or will appear as wet sand. Replace the powder if it is contaminated. Add
new powder, and clean the threads on the top of the canister. Remove and clean the cap gasket, and cap. Clean the
cap threads, and install the cap and tighten securely. If the cap is not secure, air leaks can occur which will affect
cutting efficiency.
NOTE : To check the powder level in the Powder Canister, turn the unit off to release the internal pressure in the
canister. If the canister is pressurized or the unit in the READY mode, the user will not be able to unfasten the cap
ring.
Complete the following procedure to empty the Powder Canister:
1. Turn the unit off to de-pressurized the system.
2. Open the top.
3. Remove the hoses connected to the canister top and bottom.
4. Remove the lid from the Powder Canister by turning the cap counterclockwise.
5. Loosen the two screws that secure the canister to the mounting bracket then turn the canister counterclockwise to disengage.
6. Empty the Powder Canister.
7. Use a brush or a vacuum to remove any powder remaining in the canister.
NOTE: It is necessary to empty the Powder Canister if the unit will be stored for a period of six weeks or
more. This will ensure that the powder is not subject to humid air conditions which may contribute to
“heavy” powder, causing the Orifice Plate Holes to clog.
Cleaning the Powder Canister:
If the Air Supply source contains moisture or other contaminants, the powder may clog the Orifice Plate Holes.
Complete the following procedure to unclog the holes:
1. Repeat the procedures for “Emptying the Powder Canister”, steps 1-7.
2. If powder is heavily contaminated, discard it. If the powder looks “heavy”, place the powder in a
microwaveable container. With the microwave set on high, cook the powder for 45 seconds. Set aside
and let cool.
990277 Rev. APage 19 of 46
3. Re-install the Powder Canister without the powder. Also ensure that the two screws are securely
fastened.
4. In the bottom of the canister, there are a series of five small holes. With a .0015 Endo file or an Ortho
wire, gently penetrate through the openings.
NOTE: Only remove the clogs. Too much filing will result in excess powder flow.
5. Replace the canister lid securely.
6. Ensure that the handpiece nozzle is not clogged by gently penetrating the nozzle opening with an Endo
file.
7. With the unit in the Ready position, set the “Beam Intensity” to HIGH and the Particle Energy at the
highest available pressure, point the handpiece into the KleanAir® System or vacuum. Press the
Footswitch for approximately one minute to purge the system. Return to the Standby mode.
8. Refill the Powder Canister with abrasive powder.
3.3Weekly Requirements
3.3.1Filters
Inspect all in-line filters for damage, presence of moisture, or color change.
3.3.2Pinch tube
The pinch tube should be inspected for wear and tear weekly. Replace as required.
Conditions which are common when the pinch tube fails are as follows:
1. Changes in air and powder flow will result in erratic and/or poor cutting efficiency.
2. The Particle Energy may have difficulty reaching and maintaining desired setting.
3. If the pinch tubes are not replaced when failure has occurred, an audible air leak will be apparent and
abrasive powder will eventually discharge into the chassis.
4. When changing pinch tubes, the user may inadvertently neglect to get the shoe block covers secure.
Tighten the thumb screws to minimize the gap to ensure proper performance.
3.3.3Powder Chamber
Inspect the powder chamber for moisture.
Look for powder clumps or wet powder and discard or replace as necessary.
To dry wet powder:
1. Place powder to be used in a microwave safe container.
2. Microwave on high for 45 seconds to dry the powder prior to placing in the chamber.
NOTE: Care should be taken when removing the container from the microwave, as it may be hot.
3.4Monthly Requirements
3.4.1Internal tubing
Inspect internal tubing for wear and air leakage.
Listen for audible leaks and look for powder accumulation internal to the unit.
Soapy water and a small paint brush are ideal for finding small leaks. Clean up excess powder to help isolate the leak
area.
990277 Rev. APage 20 of 46
If leaks are found, try re-seating tubing in their fittings.
If leaking persists, contact your authorized Welch Allyn / Kreativ service representative.
3.4.2Handpieces and Nozzles
The handpieces and nozzles for the Mach 6 can be sterilized by any standard dental autoclave, ultrasonic sterilizer, or
manual sterilization practices. After removal from the autoclave, it is important to allow the nozzles and handpieces to
dry completely before use. If the handpieces and nozzles are not allowed to dry, the handpiece and nozzles may
become clogged.
If clogging occurs, complete the following procedure:
1. Remove the handpiece assembly from the handpiece hose.
2. Blow air into both the nozzle and handpiece ends.
3. If the air fails to resolve the clogging, use an Endo file or Ortho wire to penetrate the nozzle opening.
The nozzles are subject to wear and will require replacement at some point in time. Indications of wearing on the
nozzle are a decrease in cutting efficiency, an undefined stream of powder flowing from the nozzle slits along the side
of the tip.
3.5Quarterly Requirements
3.5.1Pinch Tubes
The Pinch tube should be replaced quarterly. A package of is supplied with each handpiece kit.
Complete the following procedure to change a pinch tube:
1. Turn the unit off. Wait until the unit has depressurized.
2. Ensure that the unit is in the OFF position and that the power cord is disconnected from the electrical
outlet.
3. Remove the Top pinch valve block cover by turning the thumb screws counterclockwise.
4. Remove the worn pinch tube by gently pulling it from the fittings. Discard the tube.
5. Insert a new pinch tube, and place the fittings and pinch tube into the bottom block indentations.
6. Replace the top block, ensuring that the fittings and pinch tube align properly. Secure the top block
with the thumb screws.
CAUTION: Failure to ensure the top and bottom block are secure will result in an air leak situation or
may potentially cause damage to the internal components.
7. Resume normal operation.
An additional factory recommendation is to inspect the shoe block covers for wear whenever a pinch tube has been
replaced. Maintenance negligence of pinch tube replacement will result in scarred shoe block covers and may
contribute to additional internal component damage, again resulting in equipment malfunction.
3.6BI-Annual Requirements
3.6.1Pinch Valve Assemblies
Lubricate the Pinch valve assembly to ensure proper powder delivery. A Pinch Valve Maintenance Kit (P/N 150036)
is available with all of the necessary pinch valve parts.
Complete the following procedures to lubricate the pinch valve assembly:
990277 Rev. APage 21 of 46
1. Turn the unit off.
2. Ensure that the unit is in the OFF position and that the power cord is disconnected from the electrical
outlet.
3. Open the Top.
4. Remove the thumb screws, turning counterclockwise to remove the top shoe block. Discard the shoe
block. Set the thumb screws aside.
5. Pull the pinch tube from its fittings. Discard the pinch tube, and inspect the fittings for wear. Replace
the fittings if necessary.
6. With a small slotted screwdriver, remove the set screws for the bottom shoe block, turning
counterclockwise, ensuring that pressure is applied to the bottom shoe block, since a spring is behind
the shoe block which may dislodge unexpectedly. Discard the bottom shoe block. Lay the set screws
aside.
7. With the bottom shoe block removed, a spring and shoe will dislodge freely.
8. Discard the shoe. Set the spring aside.
9. With a small set of needle nose pliers, remove the retaining ring. Set it aside.
10. Remove the diaphragm. Discard it .
11. Remove the piston. Remove the o-ring from the piston, and discard it.

5.Installation Considerations
5.1Site Preparation for Welch Allyn Kreativ Air Abrasion Systems
Welch Allyn Kreativ Air Abrasion systems require an external source of clean, dry, compressed air or nitrogen and a
standard 110 or 220 volt outlet. In most cases your existing dental compressor is adequate. Compressed nitrogen or
an alternative compressed air source can be used if your present office compressor cannot supply enough pressure.

220 VAC

Welch Allyn Kreativ Mach 6 System
(11" x 11" x 13")
Handpiece
Figure 14Connection of the Welch Allyn Kreativ Air Abrasion
System
High Volume Evacuation system: Use of a high volume evacuation system (HVE) is necessary when using the Air
Abrasion System. Your in-office high volume evacuation system can be used. The abrasive should not damage your
system as long as it is properly maintained. Welch Allyn Kreativ KleanAir system used in conjunction with your
HVE will optimize the evacuation of any abrasive that escapes from the oral cavity as well as spray from rinsing and
gases of fumes from materials used in the preparation. (Review the KleanAir brochure for more information.)
There are three possible sources for compressed air/nitrogen available for use with the Welch Allyn Kreativ Air
Abrasion system. Review all three options to determine which is best for you.
• Option #1 Present In-Office Compressor System
• Option #2 Compact Compressor System
• Option #3 Compressed (bottled) Nitrogen
NOTE: Other bottled gases such as compressed air or CO2 are NOT usable. They contain water and oil which will
cause the system to clog and not work properly.
5.1.1Option #1: Present In-Office Compressor System
In most cases the Welch Allyn Kreativ Air Abrasion system can use your existing dental compressor. The following
will enable you to determine if your compressor can supply the required pressures/air:
990277 Rev. APage 34 of 46
• Air pressure: The Welch Allyn Kreativ Air Abrasion system requires a maximum of 130 PSI and a
minimum of 80 PSI of clean, dry air. Check with your compressor service company regarding the
capability of your compressor system.
• Air Dryer System: Clean, dry air is absolutely essential for the Welch Allyn Kreativ Air Abrasion
system to operate properly. Moisture or oil in the air supply can cause clogging in the abrasive flow
path and prevent the unit from operating or cutting properly. Welch Allyn Kreativ suggests that you
have your dryer system checked and serviced prior to installation of the system. Welch Allyn Kreativ
offers a small in-line dryer/filter system that can be connected in-line with the air abrasion system if
clogging problems do occur.
• Connecting the Welch Allyn Kreativ Air Abrasion system to the office air supply: Since the proper
tools and training, as well as knowledge of how your system operates, are necessary, it is important for
your compressor service company to install the air supply connection. The Air Supply Line can be
connected at any point in the Main Air Line between the System Dryer and the Operatory Chair
Regulator (see Figure14). The most common hook up is a supply line with a “quick disconnect” fitting
so that the air abrasion system can be moved easily from operatory to operatory. A 10-foot long air
supply hose with a quick disconnect fitting on each end is provided with the air abrasion system. The
fitting is a standard size and type (Parker Company P/N #393P-4-4).

5.1.2Option #2: Compressor System
Welch Allyn Kreativ has designed an optional, small, quiet, and compact compressor system that is powerful enough
to supply dry, clean air. It operates on a standard 110 or 220 volt outlet. The compressor is small enough to fit in a
cabinet or under a counter. You may want to put it in a utility room and have the air supply hose run a short distance
to the Operatory. The compressor operates so quietly that one usually cannot hear it over the noise of other
equipment/instruments already in the Operatory. The system’s simple and reliable design insures minimal
maintenance.

5.1.3Option #3: Compressed (bottled) Nitrogen
The Welch Allyn Kreativ Air Abrasion system can operate on compressed (bottled) nitrogen. Bottles and tanks of
various sizes are readily available anywhere in the country from your dental supply company or local bottled gas
supplier. The size of the bottle you order will depend on where you decide to store it. A smaller bottle could be
placed on a small cart and moved from room to room, but being smaller, it would need to be refilled more often. A
larger bottle can be stored in one place, and supply line(s) can then be run to the operatory(s) where you plan to use
the system. How long a bottle/tank will last will depend on the size of the tank and the daily usage. You should
consider the following when looking at this option:
• Size bottles/tanks that are available
• Storage requirements
• The cost of having the bottle/tank refilled
Welch Allyn Kreativ recommends a regulator that is adjustable to no more than 130 PSI. We have tested several
regulators and have found that either of the regulators listed below to be most suitable:
• Harris Company
Regulator model 425-125-580 SI
Contact your local gas supplier.
(Available from Welch / Allyn Kreativ)
• Victor Company
Regulator model VTS 253 D
Contact your local gas supplier.
CAUTION: Other regulators will work but can be adjusted to 200 PSI or higher. Damage can occur if pressure higher
than 130 PSI is applied. Damage due to extreme over pressure is not covered by the warranty.
