1. After 200 to 300 hours of operation, the oil change should be carried out for the first time. The quality of the oil should be regularly checked during the subsequent use, and the oil mixed with impurities or deteriorated must be promptly replaced. Under normal circumstances, for long-term continuous operation of the reducer, according to the operation of 5000 hours or once a year to replace the new oil, long-term decommissioned reducer, should be replaced before the re-operation of new oil. The speed reducer should be added with the same oil as the original grade, and must not be mixed with different grades of oil. The oil with the same grade and different viscosity can be mixed and used.
2. When changing the oil, wait for the extruder gearbox reducer to cool down until there is no danger of burning, but it should still be kept warm, because after cooling completely, the viscosity of the oil increases, making it difficult to drain the oil. Note: To cut off the power supply of the transmission to prevent unintentional energization;
3. During work, when the oil temperature rise exceeds 80°C or the temperature of the oil pool exceeds 100°C and abnormal noise occurs, use should be stopped. Check the reason and trouble must be eliminated. After the oil is replaced, it can be continued. ;
4. The user should have a reasonable use and maintenance rules and regulations, and should carefully record the operation of the gearbox reducer and problems found during the inspection. The above regulations should be strictly enforced.
