Fluid in the hose and proportioner is still under
pressure. Follow the Pressure Relief Procedure
in the proportioner manual.
To relieve pressure in the hose manifold after the
gun is removed, place the fluid manifold over
containers, facing away from you. Ensure fluid
valves are closed. Very slowly open fluid mani-
fold check valves 2 to 2-1/2 turn. Under high
pressure, fluid will spray sideways from the fluid
ports.
