OPERATION FUNCTIONS:
1. Power Switch
:
Controls power on/off to console. When
the AEU-425FO is turned on, the Electric
Control Console will light.
2. Handpiece Ratio Selector
:
Calibrates the Handpiece Ratio Indicator to
read accurately for four different handpiece
ratios. Push the Handpiece Ratio Selector
until the Handpiece Ratio Indicator
matches the handpiece ratio you are using.
Different handpiece ratios are required to
obtain different speed ranges for dental
procedures. Ratio settings are held in
memory even after unit is turned off.
3. Speed (RPM) Selector
:
Controls speed of motor and handpiece.
Push the up arrow to increase speed and
the down arrow to decrease speed. The
Speed (RPM) Indicator shows actual
RPM. For complete display accuracy, the
Handpiece Ratio Indicator must exactly
match the ratio of the handpiece being
used. Speed settings are held in memory
even after unit is turned off.
4. Forward/Reverse Selector:
Determines the rotation of the motor and
handpiece. A red L.E.D. light and audible
beeper indicate the reverse rotation.
5. Handpiece Water Coolant:
Switches the water coolant to the
handpiece on and off, and adjusts the
flow. When switched to the on position,
coolant water will flow when the
handpiece is in operation. Rotate the
Handpiece Coolant Flow Adjustment Knob

clockwise to decrease water flow and
counterclockwise to increase water flow.
6. Handpiece Coolant Air
- Switches the air
coolant to the handpiece on and off. When
switched to the on position, coolant air will
mix with the water flow to create a spray
when the handpiece is in operation.
7. Three-Way Air/Water Syringe
:
Pressing the left button dispenses water.
Pressing the right button dispenses air.
Pressing both buttons simultaneously
dispenses an air/water mist.
8. Optional Ultrasonic Scaler
:
See accompanying documents.
The Ultrasonic Scaler has adjustable
ultrasonic levels and a water coolant
system.
The scaler includes 3 instrument tips: The
#37 instrument is specially developed for
subgingival scaling, furcations,
supragingival fine scaling and spot
removal. The #38 tip is used for lingual and
buccal subgingival scaling and furcations.
The #39 tip is used for universal lingual
and buccal supragingival scaling.
The scaler is controlled by the Scaler
Ultrasonic Setting Adjustment Knob. Turn
clockwise to set the ultrasonics to max.
Turn counterclockwise to set the
ultrasonics to min.
9. Coolant for Optional Ultrasonic Scaler:
The coolant level is controlled by the Scaler
Coolant Flow Adjustment Knob. Turn
counterclockwise to increase coolant flow.
Verify that scaler coolant
flow of no less than
20ml/min is available at
the tip.
