For basic ram and pump operation, refer to the component manuals supplied. If you suspect that the spray tip/nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip/nozzle or hose. Pressure Relief Procedure Flush Before Using Equipment The pump was tested with lightweight oil, which is left in the fluid passages to protect parts. To avoid contaminating your fluid with oil, flush the pump with a compatible solvent before use. Turn on the air motor slider valve (BF) on both ram A and B. On, display will read: "Turn the system off?" Select Yes to turn off. Hold a metal part of the gun/valve firmly to the side of a grounded metal pail, and trigger the gun/valve to relieve pressure.
