2.1.4 Connect one end of water pipe to the water pipe to the water entrance, and
the other end to the clean water sourse. (see picture 2)
2.1.5 Choose the scaling tip according to the equirement, and x the scaling tip
with the wrench. ( see picture 3)
2.1.6 Connect the power cord to the main unit, and get through to the power. (
see picture 2)
2.1.7 Press the power switch of the main unit, then the power indicator shines.

light touch and a certain to-and-fro motion will eliminate the tartar without
obvious heating, overexetion and overatay are forbidden.
2.1.9 Vibrating intensity: Adjust the vibrating intensity according to your need,
usually adjust to the middle grade, and adjust the vibrating during the clinical
treatment according to the patient's sensitivity and the rigidity of the tartar.

the water supply to clean the handpiece and the tip.
2.1.15 Unscrew the scaling tip and sterilize it.
Note: Don't screw the scaling tips when stepping on the foot switch, and the
machine is working.
3. Maintenance and sterilization
3.1 All the scaling tips can be autoclaved.
3.2 Handpiece can be sterilized by any neutral sterilized liquid for cleaning and
sterilizing. Do not sterilize under the high temperature and pressure.
3.3 The scaling tip and wrench can be cleaned by ultrasonic cleaner.
