2.1 Scaling function
2.1.1Usage
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 switch to the max based on symbol as shown
as 3.5.2[note 1].
c) Insert the plug of the foot switch to its socket(picture 2).
d) Connect one end of the water line to the water entrance, and the other end
to the pure water source(picture 3).
e) Screw the scaling tip tightly to handpiece by torque wrench, then connect
the handpiece and the connector of cable correctly.
f) Insert the plug of the power source to its socket ,then get through to
the electricity (picture 2).
g) Switch on the main unit, then the scaling indicator and the first five lights
of power regulator shine.
h) Select a suitable scaling tip as you need, screw it on the handpiece tightly
by the torque wrench(picture 5).
i) The normal frequency is extremely high. Under the normal working state
of scaling tips , a light touch and a certain to-and-fro motion will eliminate
the tartar without heating. Overexertion and long-time lingering are forbidden.
j) Vibrating intensity: Adjust the vibration intensity as you need, generally
turn the knob to the middle grade. According to patients’ different sensitivity
and the rigidity of the gingival tartar, adjust the vibration intensity during the
clinical treatment.
k) Water volume adjust: Step on the foot switch, and the tip begins to vibrate,
then turn the water control switch to form fine spray to cool down the hand-
piece and clean the teeth.
l) The handpiece can be handled in the same gesture as a pen in hand.
2.Product function and usage

m) 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.
n) After finishing operation, keep the machine working for 30 seconds on the
water supply condition in order to clean the handpiece and the scaling tip.
o) Unscrew the scaling tip and pull out handpiece, then sterilize them.
Notice: Don't pull out the handpiece when the foot switch is stepped on and
the machine is vibrating.
2.1.2 Instruction for main components of detachable handpiece (showed in
picture 4)：
a) Nipple: The nipple can be removed. You can screw out the nipple and
clean the pole with alcohol termly.
b) Handpiece seal：The seal can be removed and cleaned with alcohol termly.
c) Handpiece: The main part of the whole handpiece, can be autoclaved under
the high temperature and pressure.
d) The connector of the cable：Connect the handpiece with the water source
and power supply of the main unit.
Notice: Keep dry when the detachable handpiece connect to the connector
of the cable.
2.1.3 Torque wrench use instruction (showed in picture 5)
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 effectively and keep
their hands away from being scratched.
b) Operation
① Take the scaling tip into the torque wrench; operate as showed in picture 5.
② Tip installation: Hold the handpiece turn the tip toward direction as showed
In picture 5 with the torque wrench. Turn two more circles when the tip stops,
then the tip is installed.
③ Tip uninstallation: Hold the handpiece, turn the wrench toward anti-clockwise
8

direction.
④ Sterilize it in sterilizer after each treatment.
⑤ The torque wrench must be cooled naturally after sterilization to avoid
scald when using next time.
⑥ Keep the torque wrench in a cool, dry and ventilated place and be clean.
c) Precaution
The following sterilizing methods are forbidden.
① Braise in liquor;
② Dip in iodine,alcohol or glutaraldehyde;
③ Torrefy in oven or microwave oven.
Notice:we are not responsible for any damage of the torque wrench directly
or indirectly made by any way in the above items.
2.2 Endo function
a) Usage process
① Fix endochuck to handpiece by endo wrench.
②Unscrew the screw cap on the endochuck.
③ Put the ultrasonic file into the hole in the front of endochuck.
④ Screw down the screw cap with endo wrench to tight up the ultrasonic file.
⑤Press option key, turn to endo function.
⑥ When ultrasonic scaler turns into endo function, only the first lead light is
on and the power is at 1st grade. Put the ultrasonic file into the patient's root
canal slowly, step on the foot switch, then make endo treatment. During the
treatment, turn up the power gradually according to the needs.
b) Notice
① When fixing endochuck, it must be screwed down.
② The screw on the endochuck must be screwed down.
③Don't press it too much when the ultrasonic file in root canal.
④Don't start up the foot switch until the ultrasonic file is in root canal.
⑤The power range is supposed from 1st to 5th grades.
