(F) must be open when you close this valve.
The fluid drain valve (H) assists in relieving fluid pressure in the displacement pump, hose, and gun; triggering the gun to relieve pressure may not be sufficient.
Install an air line filter (E) in the main air line, to re- move harmful dirt and moisture from the compressed air supply. To provide automatic lubrication of the air motor, install an air line lubricator (P) downstream from the pump air regulator (F). Install a second master air valve (D) in the main air line, to isolate the accessories for servicing.
