1 Introduction
1.1 Brief introduction
PT-A Dental Scaler and Air Polisher has both ultrasound system and air polishing
system. It is suitable for periodontal treatment and root canal irrigation in dental clini-
cal treatment. It can remove subgingival and supragingival calculus and plaque, so as
to achieve the therapeutic eect of consolidating periodontal tissue. The features of this
device are:
1) According to the selected handpiece, automatically switch the working mode.
2) The front panel adopts touch LCD screen, and the function selection and working
status indication are simple and clear.
3) The rounded vibration trajectory of the tip realizes treatment and polishing at the
same time. With small amplitude of tip, achieve painless treatment.
4) Titanium alloy tip will not hurt cementum or enamel.
5) In the automatic water supply mode, special chemical solutions such as hydrogen
peroxide, sodium hypochlorite and chlorhexidine can be used to improve the clinical
treatment eect.
6) The automatic frequency tracking system is used to automatically search for the
best working condition, which brings more stable performance of device.
7) The three-piece design of air polishing handpiece is easy to load and unload for
cleaning and maintenance.
8) The powder tank adopts a side cone structure to eectively reduce the residual
amount of powder.
9) Detachable ultrasonic handpiece and air polishing handpiece can be sterilized un-
der high temperature of 134℃ and high pressure of 0.22MPa.
10) The working process is fully automatic controlled by microcomputer, which is
convenient and simple to operate and if of high eciency.

2.5 Installation procedures
① Open the package, check whether the equipment is complete as per the packing
list, and place the main unit on a solid plane, holding it directly facing the operator.
②Connect the power adapter with main unit.
③Plug the external air pipe connector into the air intake connector on the back of
the main unit.
Figure 7 Schematic diagram of external air pipe installation
④ Insert the foot pedal plug into the foot switch socket.
⑤ Connect the ultrasonic handpiece and air polishing handpiece with corresponding
tail cords respectively, and place the handpieces on the brackets on both sides of the
main unit. The ultrasonic handpiece is on the left and the air polishing handpiece is on
the right.
Warning1: When the machine is connected to the network power supply, the pro-
tec- tion ground must be linked.
Warning2: When the machine is connected to the network power supply,do not pla-
ce or install the product where it is dicult to disconnect thenetwork power supply.
3 Function and operation
3.1 Multi-function foot pedal
① According to the installation procedures, insert the foot pedal plug into the main
unit, tighten it, and place the foot pedal face up on a at surface.
② The multi-function pedal is as shown in the gure, and the functions of each but-
ton are as follows:
Button Working mode Function
Ultrasound system air polishing system
A Standard Vibration + water Air, powder + water
B Anhydrous mode Vibration Air only
C (+A) Enhance【Note】Power increases by
two levels
Air pressure increases by
two levels

8
D Irrigation Only water spray Air+Water
【Note】In the Enhance mode, the power/air pressure is increased by three levels
based on the original level, and the maximum is level 12. When the pedal button C is re-
leased, the gear position is automatically restored to the previously set gear position.

3.2 Ultrasound system
3.2.1 Scaling
1. Install the product correctly according to the product installation steps, and the ope-
rator is facing the machine.
2. Turn on the power switch on the main unit and pick up the ultrasonic handpiece. At
this time, the panel automatically jumps into the Ultrasound system interface.
3. This machine uses the touch panel. Directly click the “G” on the panel to enter the
teeth scaling mode.
4. Select the appropriate water supply method and click on the water bottle/faucet icon
on the panel to switch between water bottle supply and external water.
5. Select proper tip as per need, and use torque wrench to tighten it to the handpiece.
6. When the foot button A is pressed, the tip vibrates, and the LED light on the head
of handpiece is illuminated, accompanied by the cooling water spray (For the rst time
after booting, as there is more air in the pipeline, it takes a few seconds to drain.) After
releasing the foot pedal, the vibration and water spray stop, and the LED light continues
to light for 10 seconds and then goes out.
7. Generally, hold the handpiece with the gesture of holding a pen.
8. The frequency of the tip is extremely high. In the condition of normal tip vibration
and water spray, lightly touch the tooth surface with the side of tip and move in a certain
to-and-fro motion to eliminate the calculus without obvious heating. Avoid local ove-
