Gearmotor is how oil change it?

helical bevel worm gearmotor at work after a certain time is needed for an oil change, usually run 200 to 300 hours after the first oil change should be carried out in future use should regularly check the quality of the oil, the incorporation of impurities or deterioration of the oil to be timely replacement. In general, for a long continuous operation since reducer speed machine, press run 5000 hours or once replaced with new oil every year, long-term disabled reducer, before re-operation should be replaced with new gear oil should be added to the same grade as the original Oil, not with different grades of oil mixed with, different grades of the same viscosity oil and allowed to mix.
variable gear motor to wait reducer oil change to cool down so far no fire hazard, but should remain warm, because after completely cooled, the viscosity of the oil increases, put the oil difficult.
