NOTE: The ports on the manifold are marked for easy
identification of components. Example: P1 is a piston
pump connection port and 2 is the location for the sole-
noid valve (See Hydraulic Schematics to identify the
function of the hydraulic lines and cartridge valves at
each port).
2. If cartridge is solenoid operated, remove nut secur-
ing solenoid to the cartridge valve. Carefully slide sole-
noid off the valve.
IMPORTANT: Use care when handling the valvecar-
tridge. Slight bending or distortion of the stem tube
can cause binding and malfunction.
