Lift Control Manifold Removal (Fig. 103)
WARNING
Before disconnecting or performing any work on
the hydraulic system, all pressure in the system
must be relieved. See Relieving Hydraulic System
Pressure in the General Information section.
1. Park machine on a level surface, lower cutting deck
(or implement), stop engine, engage parking brake and
remove key from the ignition switch.
WARNING
Make sure that cutting deck is fully lowered and
supported before loosening hydraulic lines, car-
tridge valves or plugs from lift manifold. If deck is
raised as manifold components are loosened,
deck may drop unexpectedly.
2. Thoroughly clean hydraulic hose ends and fittings on
lift control manifold to prevent hydraulic system contam-
ination.
3. Label all hydraulic and electrical connections for as-
sembly purposes.
4. Disconnect hydraulic hoses connected to the hy-
draulic fittings on the lift control manifold. Allow hoses to
drain into a suitable container. Install clean caps or plugs
on disconnected hoses and fittings to prevent contami-
nation.
5. Disconnect wire harness connectors from solenoid
coils on manifold.
6. Support manifold to prevent it from falling.
7. Remove two (2) cap screws (item 17) and lock wash-
ers (item 18) that secure manifold to machine. Remove
manifold from machine.
8. If hydraulic fittings are to be removed from lift control
manifold, mark fitting orientation to allow correct assem-
bly. Remove hydraulic fittings from manifold as needed.
Discard O- rings from removed fittings.

Lift Control Manifold Installation (Fig. 103)
1. If hydraulic fittings were removed from lift control
manifold, lubricate new O- rings with clean hydraulic oil,
position O- rings to fittings and install fittings into man-
ifold ports (see Hydraulic Fitting Installation in the Gen-
eral Information section of this chapter).
2. Position lift control manifold to machine and secure
manifold with two (2) cap screws and lock washers.
3. Remove caps and plugs from hydraulic hoses and
fittings.
4. Lubricate and install new O- rings on control man-
ifold fittings. Using labels placed during manifold remov-
al, correctly connect hydraulic hoses to lift control
manifold (see Hydraulic Hose and Tube Installation in
the General Information section of this chapter).
5. Connect wire harness connectors to solenoid coils
on manifold.
6. Check oil level in hydraulic reservoir and add correct
oil if necessary.
7. Follow Hydraulic System Start- up procedures (see
Hydraulic System Start- up in this section).
