NOTE: The ports on the manifold are marked for easy
identification of components (e.g. P1 is a gear pump
connection port and RV8 is the location for a relief
valve). See Hydraulic Schematics in Chapter 9 -- Fold-
out Drawings to identify the function of the hydraulic
lines and cartridge valves at each port location.

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