The lift control manifold on machines with a serial num-
ber from 313000001 to 314999999 is different than the
manifold used on machines with a serial number above
315000000. Both manifolds are shown in Figure 1 04.
Service for manifold valves, solenoid coils and plugs are
similar on either manifold.
NOTE: The ports on the lift control manifold are marked
for easy identification of components. See Hydraulic
Schematic in Chapter 8 - Foldout Drawings to identify
the function of the hydraulic lines and cartridge valves
at each manifold port.
NOTE: The lift control manifold u sed on machines with
a serial number from 313000001 to 314999999 has an
expander plug (item 9) installed in manifold port 4. This
plug is not a serviceable part and is used to prevent hy-
draulic flow from manifold port 1 to port 4.
NOTE: If the lift control manifold was replaced for some
reason on a machine with a serial number from
313000001 to 314999999, the replacement manifold
may have been the same manifold as used on machines
with a serial number above 315000000.
