type. Use the priming pump, to pump fresh hydraulic fluid through the
system until clean hydraulic fluid, free of air bubbles, emerges into the
container at the output port. Discard the contaminated fluid expressed

(c) Remove the hose located to the output port and, to prevent the ingress of
any contaminant, fit a blanking plug in its place.

priming inlet.
