1. After the servo planetary reducer has been operating for 200 to 300 hours, the first oil change is required. In the subsequent use, the oil quality should be checked regularly, and the oil mixed with impurities or deteriorated should be replaced in time.

　　Normally, for the reducer that works continuously for a long time, the new oil should be replaced after 5000 hours of operation or once a year. For the reducer that is not used for a long time, the new oil should be replaced before re-operation.

　　Servo planetary reducer should be filled with the same oil as the original brand, and must not be mixed with oils of different brands. Oils with the same brand but different viscosities are allowed to be mixed.

　　2. When changing the oil, wait for the servo planetary reducer to cool down and there is no danger of burning, but it should be kept warm, because the viscosity of the oil increases after it is completely cooled, and the difficulty in draining the oil will increase.Also pay attention to cut off the power supply of the transmission device to prevent unintentional power-on.

　　3. During work, when it is found that the oil temperature of the planetary reducer exceeds 80°C or the oil temperature exceeds 100°C, and abnormal noise is generated, stop using it immediately and check the cause until the fault is eliminated and the lubricating oil is replaced. In order to continue to operate.

　　4. Everyone should have reasonable use and maintenance rules and regulations. The operation of the servo planetary reducer and the problems found in the inspection should be carefully recorded. The above regulations should also be strictly implemented.
