The control manifold contains pilot pressure relief valve (5) , filter screen (4) , check valve (6) , and the differential lock control valve (8) . Pilot oil accumulator (2) and the solenoid valve for the differential lock are mounted to the control manifold.
The control manifold receives oil from pilot pump (7) . Pilot pressure relief valve (5) reduces oil from pilot pump (7) to pilot pressure. The control manifold directs pilot oil from pilot pressure relief valve (5) to the pilot valve.
The control manifold also directs oil to pilot oil accumulator (2) . Pilot oil accumulator (2) supplies oil for lowering the boom and/or the arch to the ground while the engine is stopped.
The differential lock control valve responds to a solenoid. The solenoid for the differential lock is energized or de-energized in response to the differential lock switch.
Pressure tap (1) for pilot oil pressure and pressure tap (3) for the pilot oil accumulator are located on the control manifold.
