How frequently should I change my vibratory machine's oil?

A vibratory machine's oil should be changed every 1,000 operating hours. For example, if you are running one shift of production 5 days a week, the oild should be changed every 6 months. Be sure to use Mobil 600 (SHC 626 on large machines), change the oil filter element in the filter assembly, and clean the suction/intake filter on the pump. Keep an oil change log.
