Air/Water Syringe
Air/Water and Air Only Syringe Adjustment
Adjustment knobs are located and labeled on either the front or side of unit.
Check the flow of air, water and spray from the syringe. Press the right button
for water stream. Press the left button for air. Press both simultaneously for
spray. To adjust the flow of air, turn the syringe air adjustment knob clockwise
to increase, counter-clockwise to decrease. To adjust the flow of water, turn
the syringe water adjustment knob until the desired level of flow is achieved
(see figure).
Tip Removal and Replacement
The air/water syringe is a press ring type which accommodates metal or disposable tips supplied by others. To
remove the tip, press down on the outside collar (left figure). When you feel a soft click the tip may be pulled
straight out (right figure). Hold the collar down and insert the new tip, pressing it all the way in. Release the
collar and test installation. Pull on the tip assuring proper insertion and that the locking mechanism is engaged.
Handpieces
Verify Handpiece Placements
Ensure all handpieces are placed into their correct holders and that the corresponding tubing is correctly
situated. This system uses auto holders that activate the instrument once it is removed. If any instruments are
incorrectly placed into holders, the selected instrument by the operator will fail to work. Verify all tubings
hanging straight down are not crossed and are placed in sequential order from left to right on the holder bar.
This will ensure they are placed correctly.
Handpiece Pressure
Handpiece pressure is regulated by the control block, and has been preset at
the factory for standard handpiece settings. To determine pressure, a
handpiece must be attached before reading the rectangular gauge located on
the front of the unit. Refer to the handpiece manufacturer’s manual for
pressure settings. To adjust the handpiece pressure, refer to the service section
of this Operation Manual.
Handpiece Connections and Fiber Optics Operation
Prior to connecting any air driven handpiece, it is important to determine the type of connection required for
the brand and style of handpieces you desire to use.
