The reducer should be filled with the
appropriate oil to the center of the oil gauge before putting in
operation. Excessive oil levels result in higher operating
temperatures which is as undesirable as using too little oil.
After approximately 24 hours of operation the
reducer must be drained, flushed thoroughly with light oil, and
refilled with fresh recommended oil. This flushing and refilling
should be repeated every 2000 to 2500 hours.
