NOTE: The ports on the lift/lower manifold are marked
for easy identification of components. Example: S1 is
solenoid valve S1 and P is the gear pump connection
port (see Hydraulic Schematic in Chapter 10 -- Foldout
Drawings to identify the function of the hydraulic lines
and cartridge valves at each port location).

NOTE: The lift/lower manifold assembly includes sev-
eral zero leak plugs. These plugs have a tapered sealing
surface on the plug head that is designed to resist vibra-
tion induced plug loosening. The zero leak plugs also
have an O--ring as a secondary seal. If zero leak plug re-
moval is necessary, lightly rap the plug head using a
punch and hammer before using an allen wrench to re-
move the plug: the impact will allow plug removal with
less chance of damage to the socket head of the plug.
