all hose lube through hose back into a

and pour water into the outlet. Place unit in
“flow mode” and turn Pressure Control Knob

pump outlet. Turn pressure control
counterclockwise until flow stops, then
connect material hose. If applicable, connect

material comes out the prime valve.
Close prime valve and allow the hose to fill
(prime valve sold separately).
