5 Oiling of contra-angle
Only the original oil injection nozzle can be used for oiling of contra-
angle. After disinfection of contra-angle and before sterilization, oiling
should be conducted under high pressure and high temperature.
1.Firstly, screw the injecting nozzle into jet of oil bottle. (Around 10
circles)
2.Next, plug the nozzle into the end part of contra-angle, and then
grease the contra-angle for 2-3s till the oil ow out of contra-angle head
part.
3.Vertically place the end part of contra-angle or tilt the contra-angle to
let go the redundant oil under gravity.
Warnings
