6 details of dental handpiece maintenance
1 When using the handpiece, it must be lubricated strictly according to the instruction manual. Generally, the high-speed handpiece is lubricated twice a day. Low-speed handpiece (straight machine, curved machine, motor) once a day.
2 The working pressure of the handpiece must be strictly in accordance with the instructions. Under normal circumstances, the working pressure of two-hole and three-hole handpiece is 2-2.2Kg, and the working pressure of four-hole, five-hole, and six-hole handpiece is 2.4---2.5Kg (refers to the pressure at the interface between the handpiece and the connecting pipe). The pressure must be adjusted when the new treatment machine is used, and the pressure of the treatment machine must be re-calibrated after a period of use (about one month).
3 Disinfection: High temperature steam disinfection should be used, chemical liquids and dry heat disinfection are not allowed. The disinfection temperature is 135℃, and the maximum time does not exceed 30 minutes. It must be cleaned before disinfection and lubricated after disinfection. Note: The handpiecewith quick-change connector should be removed, only the handpiece is disinfected, and the connector is not disinfected. For low-speed handpiece, remove the straight and curved heads for disinfection. When there is dirt on the surface of the handpiece, please clean it with alcohol.
