2. Installation and adjustment
2.1 Operation
2.1.1 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 the the stable plane facing to the operator.In addtion,install the device to an operator-friendly position.
2.1.2 Turn the water control knob to the max according to the direction showed in picture 1. Do not screw it over tight in case of damage. [ note 1]
2.1.3 Insert the plug of the foot switch to its socket. (see picture 2)
2.1.4 Connect one end of the water pipe to the water entrance, and the other end to the clean water source. (see picture 2)
2.1.5 Before treatment, make sure scaling tip, wrench and handpiece have been sterilized. Choose the scaling tip according to the requirement,
and x the scaling tip with the wrench. ( see picture 4)
2.1.6 Turn on the power switch. If the power indicator is lighted, the machine is ready for work.
2.1.7 Under normal working condition, the frequency of the tips is very high. Light touch and a certain to-and-fro motion will eliminate the tartar
without obvious heating. Overexertion and overstay are forbidden.
2.1.8 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.
2.1.9 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.
2.1.10 Water volume adjustment: Step on the foot switch, and the tip begins to vibrate, then turn the water control switch to ne spray to cool
down the handpiece and clean the teeth.
2.1.11 The handpiece can be handled in the same gesture as a pen in hand.
2.1.12 Be sure not to make the end of the tip touch the teeth vertically, and not use too much pressure when the tip touch the surface of the teeth,
in order not to hurt the teeth and the tip.
2.1.13 After nishing operation, keep the machine working for 30 seconds with the water supply to clean the handpiece and the tip.
2.1.14 Unscrew the scaling tip and sterilize it.

2.1.15 After operating, turn o the power switch to cut o the power, then pull o the plug of power adapter.
Note: Don't screw the scaling tips when stepping on the foot switch and the machine is working.
3. Maintenance
3.1 Troubleshooting
Fault Possible cause Solutions
The scaling tip doesn't
vibrate and there is no
water owing out when
stepping on the foot switch.
The power plug is in loose contact. Make the plug insert to the socket well.
The foot switch is in loose contact. Insert the foot switch to its socket tightly.
The fuse in the adapter or main unit is broken. Contact our dealers or us.
The scaling tip doesn't
vibrate but there is water
owing out when stepping
on the switch.
The tip is in loose contact. Screw the tip on the handpiece tightly (See Picture 4).
The connect plug between the handpiece and the circuit board
is in loose contact. Contact our dealers or us.
Something wrong with the handpiece. Send the handpiece to our company to repair.

Fault Possible cause Solutions
The amount of spouting
water is too little.
The water control knob is a low grade. Turn the knob to a high grade [note 1].
The water pressure is not enough. Enhance the water pressure.
The water pipe is jammed. Clean water pipe with multi-function syringe [note2].
The vibrating intensity
control knob is seized up. The potentiometer is damaged. Contact with the local distributor or our company.
The u-le doesn't vibrate. The screw is loose. Tighten it.

There is noise coming from
the endochuck. The screw is loose. Tighten it.
LED light don't work Poor contact Contact tightly
Something wrong with LED light Change a new one
There is no water coming
out from the handpiece
(automatic water supply
mode).
There is air in the water pipe. Turn the water control to the Max, reinsert the bottle.
If the problem still can't be solved, please contact with local dealer or manufacturer.
Manufacturer will provide circuit diagrams, component part lists, descriptions, calibration instructions to assist to service
personnel in parts repair.
3.2 Notice
[Note 1] The water control knob can adjust the water volume according to the symbol.
[Note 2] To clean the water pipe with the multi-function syringe of the dental unit ( see picture 7:)

8picture 7
a) Snip the water pipe at a distance of 10cm to 20cm from the water entrance.
b) Turn on the power switch, get through to the power.
c) Connect the multi-function syringe of the dental unit to the water pipe.
d) Screw o the scaling tip or pull out the handpiece.
e) Step on the foot switch.
f) Turn on the switch of the multi-function syringe, press the air or water into the water pipe to clean and eliminate the impurity.
[Note 3 ] If the scaling tip has been screwed on tightly and there is ne spray too, the following phenomena show that the scaling tip is damaged:
a) The vibrating intensity and the pulverization degree become weak obviously.
b) During operating, there is some buzz when the scaling tip is working.
[Note 4] If the power cable connected to the grid electricity end of the power adapter is damaged, as the power cable is not removable, for your
safety, please contact a professional for replacement.
4. Cleaning, Disinfection and Sterilization
The cleaning, disinfection and sterilization of handpiece, tip, and wrench (include torque wrench and Endo wrench) are as follow.
Unless otherwise stated, they will be hereinafter referred to as “products”.
Warnings
The use of strong detergent and disinfectant (alkaline pH>9 or acid pH <5) will reduce the life span of products. And in such cases, the
manufacturer takes no responsibility.
