Draining Oil & Flushing Reservoir
Since the apron oil reservoir supplies the one-
shot oiler, the oil is constantly being refreshed
when the reservoir is filled. However, small
metal particles may accumulate at the bottom of
the reservoir with normal use. Therefore, to keep
the reservoir clean, drain and flush it at least
once a year.
