Powder Flow Adjustment
Depressing the footswitch causes a mixture of powder and air to be discharged from the nozzle.
Control the mixture richness with the Beam Intensity Knob which adjusts the vibrator speed. We
suggest starting between the 3 and 5 position.
Pressure Behind the Nozzle
Necessary air pressure varies depending upon:
•
the material being cut.
•
the type of cut.
•
the abrading process desired.
•
the powder being used..
We suggest starting at 65 PSI (447 kPa).
Check the Progress of the Cavity Preparation
Stop frequently,(every few seconds) and make a visual inspection of the progress
.
As you begin using the Kreativ Model
Mach 4.0
or
4.1
, we suggested that you use short bursts
of air/powder mixture.
•
DO NOT continue for more than 5 seconds without stopping to make a visual
inspection.
•
For class V restorations DO NOT continue for more than
2 seconds
without stopping
to examine the results.
Use a Saliva Ejector
As with any other cavity preparation procedure, your conventional saliva ejector should be
normally positioned in the patient’s mouth to collect the saliva and rinse water.
Use Your High Volume Evacuation System
This is important when using the Kreativ Model
Mach 4.0
or
4.1
for cavity preparation or cutting
procedures. Place the HVE about
!
to 1 cm from the operative site to collect the abrasive powder.
