2 Product function and operation
2.1 Scaling function
2.1.1 Operation
a) Open the packing box, make sure that all the parts and accessories are
complete according to the packing list. Take the main unit out of the box and put
it on a stable plane.
b) Turn the water control knob to the max based on symbol as shown in
3.5.2 [ note l ].
c) Insert the plug of the foot switch to its socket (See Figure 3).
d) Water way installation:
Install the bottle reversely to the connector with adequate puried water (See
Figure 4).
e) Screw the scaling tip tightly to the handpiece by torque wrench, then
connect the handpiece and the connector of cable correctly.
f) Insert the plug of the power supply to its socket , then get through to the
power.
g) Switch on the main unit, then the scaling indicator and the rst ve power
indicators shine, auto-water indicator is on.

6
h) According to need, press water button to choose auto-water or DRY mode.
The indicator of choosen mode is on.
i) Select a suitable scaling tip as you need, screw it on the handpiece tightly by
the torque wrench (See Figure 6).
j) Step on the foot switch, the tip begins to vibrate, and the LED lamp on the
top of the handpiece shines. Release the foot switch, the LED lamp keep shining
for 10 seconds.
k) The normal frequency is extremely high. Under the normal working state
of the scaling tip, a light touch and a certain to-and-fro motion will eliminate the
tartar without heating. Overexertion and long-time lingering are forbidden.
l) Vibration intensity: Adjust the vibration intensity as you need, generally
increase the power by pressing the Increasing Power Switch to a higher grade.
According to patient's dierent sensitivity and the rigidity of the gingival tartar,
adjust the vibration intensity during the clinical treatment.
m) Water volume adjust: Step on the foot switch, and the tip begins to vibrate,
then turn the water control knob to form ne spray to cool down the handpiece
and clean the teeth.
n) The handpiece can be handled in the same gesture as a pen in hand.
o) During the clinical treatment, be sure not to make the end of tip touch the
teeth vertically and not to make the tip overexert on the surface of the teeth in
case of hurting the teeth and damaging the tip.
p) After nishing operation, keep the machine working for 30 seconds on the
water supply condition in order to clean the handpiece and the scaling tip.
q) Unscrew the scaling tip and pull out handpiece, then sterilize them.
Notice:
①Don't pull out the handpiece when the foot switch is stepped on and the
machine is producing ultrasonic vibration.
②Please don't choose dry mode unless needed in the treatment, please don't
make the machine work under dry mode for a long time. The teeth will be hurt if
the handpiece and tips get overheat during the treatment.
2.1.2 Instruction for main components of detachable handpiece (See Figure 5):
a) Nipple: The nipple can be removed. You can screw out the nipple and clean
the pole with alcohol termly.

under the high temperature of 134°C and high pressure of 0.22Mpa.
Notice: Keep dry when the detachable handpiece connects to the connector of

7
the cable.
2.1.3 Instruction of torque wrench (See Figure 6)
a) The torque wrench's structure is designed in special way which can control
the strength of the scaling tip's installation properly and correctly. It also can
guarantee the operator screw or unscrew the scaling tip eectively and keep their
hands away from being scratched.
b) Operation
① Take the scaling tip into the torque wrench, operate as showed in gure 6.
②Tip installation: Hold the handpiece, turn the tip toward direction as
showed in gure 6 with the torque wrench. Turn one more circles when the tip
stops, then the tip is installed.
③Tip uninstallation: Hold the handpiece, turn the wrench toward anti-
clockwise direction.
④Sterilize it in sterilizer after each treatment.
⑤The torque wrench must be cooled naturally after sterilization to avoid
scald when using next time.
⑥Keep the torque wrench in a cool, dry and ventilated place and keep it
clean.
2.2 Auto-water supply function
2.2.1 Usage process
a) Pull out the water bottle vertically.
b) Open the lid, ll the bottle with adequate puried water and tighten the lid.
c) Clean the joint and interface of water bottle.
d) Place the bottle with water upside down, insert the joint into the interface
vertically (See Figure 4).
e) Press "WATER" to choose auto-water supply.
2.2.2 Notice
