1. Under normal circumstances, for helical gear reducers that work continuously for a long time, the new oil should be replaced by 5000 hours of operation or once a year. For reducers that have been out of service for a long time, they should also be replaced with new oil before re-operation. The same oil must not be mixed with oils of different grades. Oils with the same grade but different viscosity are allowed to be mixed.
2. When changing the oil, wait until the hardened gear reducer has cooled down and there is no danger of burning, but it should still be kept warm, because after complete cooling, the viscosity of the oil will increase and it will be difficult to drain the oil. Note: Cut off the power supply of the transmission to prevent accidental power-on.
3. During work, when the oil temperature rises above 80°C or the oil pool temperature exceeds 100°C and abnormal noise is found, stop using it, check the cause, remove the fault, and replace the lubricating oil before continuing to run .
4. The user should have reasonable use and maintenance rules and regulations. The operation of the helical gear reducer and the problems found during the inspection should be carefully recorded. The above regulations should be strictly implemented.
