To avoid splashing fluid in the eyes, wear eye protec-
tion. The fluid shutoff valves and ratio check valves are
retained by mechanical stops that prevent accidental
removal of the valve stem while the manifold is pres-
surized. If you cannot turn the valve stems manually,
relieve the system pressure, then disassemble and
clean the valve to remove the resistance.
