An optional auxiliary hydraulic valve kit is available. The kit is intended to expand
the hydraulic capability for front mounted attachments. The kit includes a dual
coil cartridge style solenoid valve controlled by a panel mounted switch. The
cartridge valve manifold is located at the front right side of the machine under
the operator platform.
Removing and Installing the Auxiliary Hydraulic Valve Manifold
1. Park the machine on a level surface, lower the cutting unit (or attachment),
engage the parking brake, set the key switch to the O
FF
position and remove
the key from the key switch.
2. Label and disconnect wire harness connectors from the cartridge valve
solenoids.
3. To prevent contamination of hydraulic system during manifold removal,
thoroughly clean exterior of manifold, hose connections, and fittings.
4. Label and disconnect the hydraulic lines from manifold and put caps or plugs
on open hydraulic lines and fittings to prevent system contamination.
5. Remove the fasteners securing the manifold bracket to the machine and
remove the manifold assembly.
6. Install the manifold in reverse order.
7. Remove the caps and plugs from the fittings and hoses. Properly connect
the hydraulic lines to the manifold; refer to Installing Hydraulic Hoses and
Tubes (O-Ring Face Seal Fitting) (page 5–7) .
8. Connect the wire harness connectors to the cartridge valve solenoids.
