Functional Description
The power Indicator LED is illuminated when the unit is ON and ready for use. This
indicates that AC input power is connected to the unit.
Kreativ Models
Mach 4.0
and
4.1
provide a controlled mixture of abrasive powder
particles in a dry air stream and delivers this mixture through a nozzle.
The input air supply is routed throughout the system after passing through the main air
solenoid and coalescing filter. One path is through the main regulator (used to set the
desired operating pressure on the control panel) to the mixing chamber where the abrasive
particles are picked up. From there the air carries the particles through the main pinch
valve and on to the handpiece/nozzle when the footswitch is depressed. The second path
is through the pinch valve regulator and pinch valve control system.
The Beam Intensity control regulates the amount of abrasive particles fed into the main air
stream through the mixing chamber.
The air stream combined with abrasive powder is able 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 handpieces are offered with specific orifice (nozzle)
sizes to enable the practitioner to accomplish particular tasks. In addition, a selection of
abrasive powder is available to accommodate all desired uses. Nozzle and abrasive
powder types are listed in Section 9.
When the Power switch is set to
OFF
the unit automatically bleeds off the internal air
pressure.
Caution
Do not attempt to open the covers of the unit with power turned on!
