NOTE: The ports on the lift control manifold are marked
for easy identification of components (e.g. P is the sup-
ply connection port and R7 is the location for the lift 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.
