NOTE: The ports on the manifold are marked for easy
identification of components (e.g. P is the gear pump
connection port and R1 is the relief valve port). See Hy-
draulic Schematics in Chapter 9 -- Foldout Drawings to
identify the function of the hydraulic lines and cartridge
valves at each port location.

NOTE: The lift control manifold uses several zero leak
plugs. These plugs have a tapered sealing surface on
the plug head that is designed to resist vibration induced
plug loosening. The zero leak plugs also have an O--ring
as a secondary seal. If zero leak plug removal is neces-
sary, lightly rap the plug head using a punch and ham-
mer before using an allen wrench to remove the plug:
the impact will allow plug removal with less chance of
damage to the socket head of the plug.
