4.3 The scaling tip and wrench can be cleaned by ultrasonic cleaner.

5. Contraindication

5.1 The patient who has hemophilia is not allowed to use this equipment.

5.2 The patient or doctor who with heart pacemaker is forbidden to use this equipment.

5.3 The heart disease patient, pregnant woman and children should be cautious to use the equipment.

6. Storage and maintenance

6.1 The equipment should be handled carefully and lightly. Be sure that it is far from the vibration, and is installed or kept in a cool, dry and ventilated place.

6.2 Don't store the machine together with the articles that are combustible poisonous, caustic, or explosive.

6.3 This equipment should be stored in a room where the relative humidity is ≤

80%, atmospheric pressure is 50kPa to106kPa, and the temperature is -10℃ to

+50℃.

6.4 Please turn off the power switch and pull out the power plug when the

7.2 Notice

[ Note 1 ] The disassembly of the handpiece (As showed in picture 3): a) Remove the screw from the cover, pull out the potentiometer vertically, then take off the cover from the end of the machine lightly (there is a line connecting the cover and the machine, don't use too much strength). The inner of the machine is as showed in picture 3.

Picture 3 The disassemblt of handpiece b) Pull out the water pipe in the handpiece cable from the coupling between the water control knob and the water pipe.

c) Pull out the lead plug from circuit board and untie the string.

d) Hold the joint of handpiece cable and the main unit and push it into the main unit about lcm, then pull out the cutting sleeve from the cable.

e) Take off the handpiece from the main unit, and the disassembly is finished.

The assembly of handpiece is on the contrary. Be sure not to assemble the lead

plug in a wrong direction, otherwise the tip will be electriferous.

Check-up method: get through to the power, step on the foot switch, and checkup the scaling tip with electric pen. If the electric pen shines, the scaling tip is electriferous. Turn off the machine and then insert the lead plug correctly.

[ Note 2] Turn the water control knob towards anticlockwise direction, when the knob can't be turned any more, it comes to the min. On the contrary direction, the water volume increases step by step till the knob is back-out. The grade of the potentiometer is from gear l to 9. The ninth grade is the max. Be sure not to overdo.

[ Note 3] To clean the water pipe with the multi-function syringe of the dental unit

(as showed in the picture 4): a) Snip the water pipe at a distance of 10cm to 15cm 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) Step on the foot switch.

e) Turn on the switch of the multi-function syringe, press the air or water into the water pipe in the machine, then eliminate the impurity in the water pipe.

Picture 4 Multi-fuction syringe

[ Note 4] If the scaling tip has been screwed on tightly and there is fine spray too, the following phenomena shows that the scaling tip was damaged: a) The vibrating intensity and the pulverization degree become weak obviously.

b) When operating, there is some buzz when the scaling tip is working.

8. Precaution

8.1 Notice when using equipment

8.2 Keep the scaler clean before and after operation.

8.3 The scaling tip, wrench and handpiece must be sterilized before each treatment.

8.4 Don't screw the scaling tip when stepping on the foot switch.

8.5 The scaling tip must be fastened. There must be fine spray coming out from the tip when operating.

8.6 Change a new one when the tip is damaged or worn excessively.

8.7 While scaler working ,the heat of scaling tip will become higher if there is no water flowing out.Please keep the water flow smoothly.

8.8 Don't twist or rub the tip.

8.9 Don't use impure water source, and be sure not to use normal brine instead of pure water source.

8.10 If use the water source without hydraulic pressure, the water surface should be one meter higher than the head of the patient.
