2. Safety

2

The Kreativ Mach 5.0 and Mach 5.0 PLUS systems are designed for use only by and
on the order of a dentist.

Warnings

Always wear protective eye equipment in order to avoid corneal abrasion or irritation if
particles are deflected into the eye. This applies to the dentist, staff, and patient.

A rubber dam is recommended in order to avoid injury to gingiva or other soft tissue,
and for interproximal preparations to protect adjacent tooth surfaces.

AND OTHER SPECIFIED HAZARDS ONLY

IN ACCORDANCE WITH CAN/CSA C22.2 NO. 601.1

21ZJ

Chapter

Never direct the handpiece to an open pulp chamber or at pulpal exposures. Also
never place the handpiece in direct contact with the gingiva when the air pressure is
activated. While the abrasive stream will not cut the gingival tissue, it may irritate it.

All Kreativ Mach 5.0 and Mach 5.0 PLUS accessories which come into contact with
the patient should be sterilized prior to each use. Always disinfect the handpiece cradle
in the remote control unit before each patient use.

Always use your high volume evacuation system when using the handpiece of the
Kreativ Mach 5.0 or Mach 5.0 PLUS. Have the dental assistant place the high volume
evacuation system in close proximity to the operative site.

Make sure that the Kreativ Mach 5.0 and Mach 5.0 PLUS systems are connected to a
properly grounded electrical outlet.

Always replace fuses with fuses of the proper rating, as indicated in the Chapter 1.

Cautions

For dental cleaning (prophylaxis) procedures, be absolutely sure that the
chamber and hose have been completely cleared of all abrasive powders and use
only bicarbonate in the chamber.

Page 8 990008 Rev. H

The handpiece should be directed precisely at surfaces and tooth structures which are
to be modified or removed. The nozzle tip should be placed a few millimeters from the
tooth and angled toward the area to be removed or modified. Unlike the high speed
handpiece, the Mach 5.0 nozzle cuts only directly from the end; there is no side cutting.

Do not attempt to service the unit beyond those items described in the maintenance
section. Call your nearest Welch Allyn / Kreativ service representative for instructions.

Practice on extracted teeth prior to utilizing the Mach 5.0 and Mach 5.0 PLUS on
patients. Begin with the 27.5 micron aluminum oxide powder. Use only short bursts,
carefully monitoring your progress. Most users prefer the 27.5 micron powder at a
Particle Energy setting of 50 to 80 psi due to improved patient acceptance.

Do not substitute non-Kreativ, Inc., materials or accessories. Use of materials or
accessories supplied by other manufacturers may result in damage to the unit and will
void the factory warranty.

Use only clean dry air. Make sure that your air compressor system utilizes air dryer
filter systems and that they are fully operational. Any moisture or oil in the air supply
will adversely affect the performance of your Mach 5.0 or Mach 5.0 PLUS.

When using the Mach 5.0, check to be sure that your air system produces at least the
minimum pressure and flow rate indicated in the Air Requirements section of the
Specifications in Chapter 1.

Sound clinical judgment, good common sense and proper training are essential to the
successful use of the unit in order to provide safe and efficient patient care.

Always follow “standard of care” protocols in performing dental operative procedures.

The handle on the top of the Mach 5.0 PLUS units is intended to be used to pull the
units and is not meant for picking up the units.

Caution: Connecting the instrument’s input air supply line to a water outlet will
lead to damage to the instrument which is not covered under the limited
warranty. Repairs for such damage are at the customer’s expense.

Functional Description

When the unit is initially turned on, all lights on the Control Module will light and the
Beam Intensity and Particle Energy windows will show “8.8.8.” until the diagnostics are
complete (indicating the unit is ready to operate). The values shown will be the previous
settings used.

Kreativ Mach 5.0 and Mach 5.0 PLUS systems provide a controlled mixture of
powder particles in a dry air stream and delivers this mixture through a nozzle.

Three primary paths are provided for the air supply within the unit. One is to the
Exhaust Control Valve, another to the Abrasive Control Valve, and the third is through
the Mixing Chamber and the Abrasive Control Valve Tube to the nozzle. In the mixing
chamber, the stream of dry air is mixed with powder particles.

When the Air switch is set to “On”, the On/Off Air Valve Switch allows the air to flow
to the Mixing Chamber. With the footswitch depressed, the Abrasive Control Valve is
opened. This opens the path for the stream of powder particles from the Mixing
Chamber to the nozzle. The Beam Intensity and Particle Energy can be adjusted to
provide optimum powder flow.

The air stream combined with abrasive powder has the ability to cut and etch tooth
structure and ceramic. The abrasive powder/air stream is directed through a light,
flexible hose to the handpiece for precise cutting. Various nozzles and handpieces are
offered with different orifice sizes and angles to enable the practitioner to accomplish
specific tasks. In addition, a selection of abrasive powder is available. Nozzle and
abrasive powder types are listed in Chapter 9.

CAUTION: The unit should only be powered down with the Air control in
“Standby” mode.

NOTE: The unit will automatically go into “Standby” if left unattended for approximately
10 minutes.

When the Power switch is set to Off, the unit automatically bleeds off the internal air
pressure.

WARNING: Do not attempt to open the doors of the unit with power turned on!

4. Unpacking and Setup

4

General Information

SAVE THE CARTON!

The Mach 5.0 and Mach 5.0 PLUS and all accessories are shipped in a single
container. When unpacking, check items against the packing list included with the unit.

The shipping container and packing materials should be retained in the
unlikely event that the instrument has to be returned to the factory for service
or repair.

Chapter

To operate the Mach 5.0, the unit requires an external source of either clean, dry,
compressed air, or nitrogen together with a properly adjusted pressure regulator. For
additional information consult your Kreativ, Inc. dealer.

The Mach 5.0 PLUS instrument has a built-in air compressor, thus eliminating the need
for connection to an external air supply.

It is necessary to connect to a properly grounded electrical outlet.

Unpacking and Setup

Remove the Mach 5.0 or the Mach 5.0 PLUS unit from the shipping container and
proceed as follows:

• Unlock and open the left side door gently.

• Remove the foam packing (2 pieces) which prevents the vibrator from moving

during shipping. Retain the foam with the shipping box and packing materials. If the
unit is to be shipped again, the vibrator support foam packing should be reinstalled
to prevent possible damage to the vibrator and its mounts.

CAUTION: Failure to remove the foam packing will result in improper vibrator
operation and powder flow.

Page 17 990008 Rev. H

• On Mach 5.0 PLUS only, remove the black plug from the air inlet on top of the
compressor module, and replace with the included filter.

CAUTION: Failure to replace the black plug with the filter will result in low air
condition, and damage to the compressor unit.

WARNING: The use of compressed oxygen as a gas supply for the unit
presents the possibility of having a gas that supports flammability. Under
NO circumstances should oxygen be used.

Air Supply Requirements (Mach 5.0 only)

For the Mach 5.0 only, be sure that the supplied air pressure and air flow volume to the
unit meet the minimum Air Requirements indicated in the Specifications section in
Chapter 1. Moisture filters must be used since compressed air lines may be
contaminated with moisture, oil or dirt, which are detrimental to the performance and
operation of the unit. Kreativ can supply a product (the Klean Pak) to assure a dry air
supply.

Caution: Connecting the instrument’s input air supply line to a water outlet will
lead to damage to the instrument which is not covered under the limited
warranty. Repairs for such damage are at the customer’s expense.

Electrical Requirements

Reference the Specifications section of Chapter 1 of this manual for the power
requirements of the unit. The power requirements of your instrument are located on the
system label on the back cover of the instrument. Verify the unit is set up correctly for
your electrical supply. When replacing fuses, only use fuses supplied by Kreativ in your
customer kit. If your requirements are different, consult Kreativ, Inc., or your dealer
before operating this instrument.

• •

Inspect the powder chamber for moisture contamination. Look for powder clumps
or wet powder and replace as necessary. Refer to Chapter 5 for detailed
instructions.

Exhaust bottle

• •

Remove and clean the exhaust bottle filter. When replacing, make sure all threads
and mating surfaces are clean and tight.

Pinch tubes

• •

There are three pinch tubes inside three pinch valves located between the exhaust
bottle and the powder chamber. Remove the pinch tubes by removing two thumb
screws and the black cover block. Pull the tube from the hose assembly. Inspect

Page 26 990008 Rev. H

the tubes for signs of wear and replace with new tubes as necessary. Realign the
pinch tube assembly with the grooves and securely tighten the thumb screws.

Monthly Requirements

Compressor Oil (Mach 5.0 PLUS only)

• •

The Mach 5.0 PLUS is equipped with a portable compressor that does not require
general maintenance, except adding oil. The compressor is equipped with a viewing
window with a minimum/maximum indicator line. If the oil is below the minimum
line, add oil as follows;

1. Ensure the unit power is off and the power cord is removed.

2. Open the access door on the right side of the unit.

3. Remove the oil fill bolt from the top of the compressor head.

4. Using the bottle of oil and extra tubing shipped in the accessory kit, install
the tubing to the top of the oil bottle to allow access to the oil fill hole.
Squeeze small amounts of oil at a time, allowing time to settle before
rechecking the level indicator. DO NOT OVERFILL.

5. Replace top bolt and ensure it is tight.

Oil overflow bottle (Mach 5.0 PLUS only)

• Locate the clear oil overflow bottle at the bottom shelf of the Mach 5.0 PLUS unit.

Inspect the level of oil, and empty as necessary. Excess oil should be disposed of
as you would automobile motor oil.

Internal tubing

• Inspect internal tubing for wear and air leakage. Listen for audible leaking sounds

and look for powder accumulation internal to the unit. Soapy water and a small
paint brush is ideal for finding small air leaks. If a powder leak occurs, inspect the
tubing going from the pinch valves to the exhaust bottle first, paying particular
attention to any “Y” fittings. If no damage is found, make sure the exhaust bottle is
empty, the exhaust bottle filter is clean and tight, and excess powder is cleaned from
the unit. Clean up excess powder to avoid contamination of other components and
to help isolate the leak area.

Handpiece Nozzles

• Inspect all the handpiece nozzles for wear, paying close attention to the carbide insert

at the end of the tip. If there are any slits or chips, replace the nozzle. A worn
nozzle will greatly effect the performance of cutting and powder flow control. It is
possible to have a worn nozzle without any visible signs.
