1、 Selection of lubricating oil When the peripheral speed of medium and high grade gears of the reducer is more than 2.5m/s, or the ambient temperature is more than 35~50 ℃, medium load industrial gear oil 320 is recommended. If the reducer manufacturer has requirements or other regulations on the oil used for the reducer, the reducer shall be selected according to the requirements or regulations of the reducer manufacturer.

2、 The lubricating oil shall be replaced after 300~600 hours of first use. After that, replace the lubricating oil every time the reducer works for 4000~6000 hours.

3、 The starting oil supply reducer shall be lubricated with circulating oil if it is started with full load for more than one day (i.e. no working condition), and the lubricating oil shall be supplied to the place to be lubricated before starting. If the oil pool is immersed in oil for lubrication, it is recommended to manually supply lubricating oil to the top half of the gear from the window before starting.

4、 The amount of oil injected into the tank for oil pool lubrication shall be the standard parameter or refer to the reducer manufacturer's instruction manual. If circulating oil lubrication is used, it is recommended to control the oil volume at 0.5L/KW, or calculate according to the heat balance and adhesive strength.
