After the Needle wheel motors runs for 300 hours, the oil should be changed for the first time. The quality of the oil should be checked regularly during the subsequent use. The oil mixed with impurities and deterioration must be replaced in time. Under normal circumstances, for long-term continuous operation. For the reducer, replace the new oil with 5000 hours of operation or once a year. The gearbox that has been deactivated for a long time should be replaced with new oil before re-running. The reducer should be added with the same oil as the original grade. It should not be mixed with different grades of oil. The oils with the same grade and different viscosity are allowed to be mixed.
When changing the oil, the pinwheel motor should wait for the reducer to cool down without burning danger, but it should remain warm, because after the complete cooling, the viscosity of the oil increases and it is difficult to drain the oil. Note: Turn off the power to the drive to prevent unintentional energization.
When the Needle wheel motors is working, when it is found that the oil temperature rise exceeds 80 °C or the oil pool temperature exceeds 100 °C and abnormal noise is generated, the use should be stopped. Check the cause, the fault must be eliminated, and the lubricant should be replaced. Keep running.
