1. Shut off the bleed-type air valve (B).
2. In a spray system, hold the gun (S) firmly against a
grounded metal pail and trigger the gun to relieve
the fluid pressure.
3. Place the drain tube (K) in a waste pail. Open the
drain/circulation valve (J) to relieve any fluid pres-

snugly. Do not overtighten the fittings.
NOTE: Before using he pump, re–torque fluid
cover screws (38) to 10 ft–lb (13.6 NSm).
5. Place the suction tube (L, if used) in the fluid to be
pumped.
6. Place the fluid hose (P) in a container.
7. Close the drain/circulation valve (J).
8. Close the pump air regulator (F). Open all bleed-
type master air valves (B, E).

open while continuing with the following step.
Slowly open the air regulator (F) until the pump
starts to cycle. Allow the pump to cycle slowly until
all air is pushed out of the lines and the pump is
primed.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the
air regulator. Remove the suction tube from the
solvent and place it in the fluid to be pumped.
