2.2 Product installation
2.2.1 Set up external dental devices
Water supply system：
Pressure: 0.7bar-2.2bar(70-220kPa)
Temperature: Up to40℃
Air supply pressure:
Adjust the air supply pressure of the external dental equipment to obtain
the air supply pressure of 3.5 bar to 4.5 bar (350-450kPa).
[Note]: Excessive air pressure will cause cracks or ruptures on the powder
storage chamber and powder storage chamber cover of the Dental Air
Polisher, and even cause harm to the human body.

2.2.2 Installation and connection
2.2.2.1 Connection between Dental Air Polisher and handpiece pipeline
After drying the Dental Air Polisher interface and the handpiece pipeline
interface with an air gun, directly insert the Dental Air Polisher interface
into the handpiece pipeline, and then tighten the nut of the pipeline.
[Note]: Fully dry the Dental Air Polisher interface and the handpiece
pipeline interface before connection, so as to avoid the spray-head
blockage from damp powder during use.

2.2.2.2 Handpiece connection
After drying the inside of the handpiece and the Dental Air Polisher
interface, directly insert the handpiece into the handpiece interface of the
gun for connection.
[Note]: Fully dry the Dental Air Polisher interface and the handpiece

11
pipeline interface before connection, so as to avoid the spray-head
blockage from damp powder during use.

3. Product function and operation
3.1 Powder loading
After connecting the Dental Air Polisher, unscrew the powder storage
chamber cover of the gun, put the powder into the chamber, clear the
powder at the thread position of the powder storage chamber cover, and

12
then tighten the cover.

3.2.1 Supragingival air polishing
3.2.1.1 After loading the powder, please spray in the container outside
the oral cavity for 1~3 seconds in advance to ensure that the air and water
can be sprayed evenly before treating the patient.
3.2.1.2 Generally, the handpiece is held in a pen-holding position.
3.2.1.3 When using an Dental Air Polisher for normal air polishing, it is
recommended that the spray-head air outlet and the tooth surface be kept
at a distance of 3-5mm, and the air polishing direction is recommended to
be at an angle of 30-60° with the tooth surface, as shown in Figure 7.

3.2.2 Subgingival air polishing

14
3.2.2.1 Install an accessory nozzle before use. Screw in the nozzle to
the top of the subgingival handpiece, and then tighten the nozzle with a
wrench (as shown in Figure 8).
3.2.2.2 After loading the powder, please spray in the container outside
the oral cavity for 1~3 seconds in advance to ensure that the air and water
can be sprayed evenly before treating the patient;
3.2.2.3 Generally, the handpiece is held in a pen-holding position.
3.2.2.4 When using the subgingival handpiece for normal subgingival
air polishing, it is recommended to use a nozzle to remove the bioflm in
the periodontal pocket at subgingival 4-9mm, and perform up and down
motion for scaling.
3.2.2.5 The air polishing time of each periodontal pocket is
recommended for no more than 5 seconds.
3.2.2.6 Please ensure that the handpiece has a normal waterway
before use. Adjust the water flow and air pressure of the main unit to an
appropriate level according to the conditions of biofilm or pigment when
scaling. Do not spend too much time in local air polishing when scaling.

3.3.3 Daily maintenance
·Pay attention to daily check whether the handpiece of the Dental Air
Polisher is cracked, deformed or falling off, to ensure that the handpiece
can be used normally; pay attention to check and clean the sealing ring
to ensure its integrity and cleanliness, otherwise it will affect the product
sealing and normal operation;
·Keep the Dental Air Polisher dry. Rain, moisture and various liquids
may damp the powder and affect its normal use;
·Do not throw, beat or vibrate the Dental Air Polisher. Rough treatment
of the gun will damage the strength and sealing of equipment.
·Do not paint the instrument with pigment, which will leave debris in
the detachable parts and affect the normal operation.
