OUTRIGGER CONTROL MANIFOLD
Description
There are two outrigger control manifolds utilized on the
crane, one for the front outriggers and one for the rear
outriggers Figure 2-33. Each manifold consists of four
normally closed two position two way solenoid valves. They
are mounted inside the frame on their respective outrigger
box.
When energized, the solenoid shifts the spool to open
allowing extension or retraction of the outrigger cylinders.

3. Remove the bolts and nuts securing the manifold to the
outrigger box; remove the manifold.
Inspection
Visually inspect the valves and hydraulic connections for any
evidence of leaks or other damage. Check security of the
electrical connections. Inspect the wiring for any evidence of
cracks or breaks.
Installation
1. Position the manifold on the mounting; secure with the
nuts and bolts.
2. Connect the electrical connectors to the solenoids as
marked during removal.
3. Connect the hydraulic lines to the valves as marked
during removal.
