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.
