Fluid in the hose and proportioner is still under pres-
sure. Follow the Pressure Relief Procedure in the pro-
portioner manual.
To relieve pressure in the hose after the gun is
removed, place the fluid manifold over containers, fac-
ing away from you. Very carefully open the fluid
valves. Under high pressure, fluid will spray sideways
from the fluid ports.
