Column A gives the maximum fluid pressure developed at 100 psi (0.7 MPa, 7 bar) of incoming air pressure. Column B gives the minimum working pressure required for all system components, based on the automatic relief valve settings. Components included by Graco with the models listed meet or exceed this requirement. Models with Two Displacement Pumps...

Operation Checking the Mix Ratio 10. While observing the pump outlet gauges (J2), adjust the resin and hardener drain valves (P1,P2) NOTE: Since this is a fixed ratio system, you typically until the gauges show your normal operating do not have to check the mix ratio. pressure.
Shutdown and Care of the System Pressure Relief Procedure If you suspect that the nozzle or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the WARNING nozzle or hose end coupling and relieve pressure gradually, then loosen completely.
Troubleshooting WARNING WARNING To reduce the risk of serious bodily injury, always Never operate the pump with the air motor plate follow the Pressure Relief Procedure on page 21 removed, to reduce the risk of serious bodily injury, whenever you shut off the pump, when checking or including amputation, from moving parts inside the servicing any part of the dispensing system, when air motor housing.
