*To determine if the fluid hose or gun is obstructed, follow the Pressure Relief Procedure on page 8. Disconnect the fluid hose and place a container at the pump fluid outlet to catch any fluid. Turn on the air just enough to start the pump (about 20–40 psi [0.14–0.3 MPa, 1.4–2.8 bar]). If the pump starts when the air is turned on, the obstruc- tion is in the fluid hose or gun.

NOTE: If you experience air motor icing, contact your Graco distributor for assistance.
