3.1 Check the bolts and abnormalities of the device. After about 100 hours of operation, check the pre-tightening torque of the bolts of the inner ring and the outer ring device; look at it once every 500 hours.
If it is used, it will show abnormal phenomena such as noise, impact and power increase; it should be stopped and inspected.
3. 2 smooth slewing bearing behind the device; according to the actual application conditions; fill the appropriate smooth grease; and should fill the bearing while filling the edge to make the smooth grease evenly distributed; until the new grease starts to squeeze the sealing lip to stop. 50~ per distance Filling once in 100 hours; in the higher environment and more dusty conditions, the grease filling cycle should be shorter.
