(3) tap the foot switch to adjust the water to the appropriate flow rate and the air to the appropriate pressure, and the high speed dental handpiece standard pressure is between 0.2-0.25 KGF /cm2.

(4) note: before the loading of the dental handpiece, it is strictly prohibited to step on the foot switch, or it will cause three petal springs to rotate out, thus pushing them against the back cover and both of them will be damaged.

3.  When using dental handpiece

①　care must be taken in the use of the dental handpiece, which is delicate      and slight. Brutal operation is strictly prohibited. Do not drop the dental handpiece to the ground.

②　no matter how the Angle is, should follow the way of up and down pull   operation, do light touch, touch, must not be lateral force.

③　the improved pen-holding method is adopted to hold the mobile phone, to find the stable fulcrum and to operate intermittently.

⑨　the radial swing of the dental handpiece rotor is serious. It is strictly prohibited to use the dental handpiece when the rotor moves vertically. It is strictly prohibited to use the dental handpiece when there is no water or water shortage.

⑩　the air pressure and water pressure will change with the use of the treatment table. Therefore, the air pressure and water pressure should be checked frequently during clinical operation to ensure the normal use of dental handpiece.

4.   After using the dental handpiece

(1) Clean

After the use of dental handpieces, clean them as soon as possible, otherwise the dirty things will solidify and be difficult to clean.Before the pins are unloaded, clean the crumbs from the work head with water mist, then scrub with 75% alcohol.Or use ultrasonic dental handpiece cleaning machine to clean.Which method to use depends on the specific situation of each clinic.

The pneumatic spray oil tank is the most ideal lubrication tool, which can not only lubricate the dental handpiece, but also achieve the effect of cleaning the bearing and the wind wheel.

5.  Sterilization of dental handpiece.

There are several points that must be noted before sterilization by means of high temperature and high pressure steam sterilizer.

(1)Determine the reliability of sterilizing effect of sterilizer.

(2)Make sure that the dental handpiece can be sterilized at high temperature. 

(3)The disinfection package should be able to withstand the conditions of disinfection, not easy to damage, with good thermal steam penetration, and can prevent the invasion of microorganisms, to ensure that the dental handpiece to achieve sterilization.
