1. After 200-300 hours of operation, the first oil change shall be carried out, and the quality of oil shall be checked regularly in future use. The oil mixed with impurities or deteriorated shall be replaced in time. In general, for the reducer that works continuously for a long time, replace it with new oil according to the operation time of 5000 hours or once a year. For the reducer that is out of service for a long time, replace it with new oil before re operation. The reducer shall be added with the same oil with the original brand, and shall not be mixed with oil of different brand. Oil with the same brand and different viscosity is allowed to be mixed;
2. When changing oil, it is necessary to wait until the reducer cools down and there is no danger of combustion, but it should still be kept warm, because the viscosity of oil increases after complete cooling and it is difficult to drain oil. Attention: cut off the power supply of the transmission device to prevent inadvertent power on;
3. During operation, when the temperature rise of oil exceeds 80 ℃ or the temperature of oil pool exceeds 100 ℃ and abnormal noise occurs, stop using, check the cause, eliminate the fault, replace the lubricating oil, and then continue to operate;
4. The user shall have reasonable use and maintenance rules and regulations, carefully record the operation of the reducer and the problems found in the inspection, and the above regulations shall be strictly implemented.
