NOTE: The ports on the lift control 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 Hydraulic Schematics in Chapter 9 -- Foldout Draw-
ings to identify the function of the hydraulic lines and car-
tridge valves at each port location.
