FLOW DIVIDER
MANUAL OVERRIDE
• Remove the solenoid valve
connector on the flow divider (figure
#3.51).
• With a power supply or battery, feed
the coil with 12 volts DC on pin 1
and 2 (figure #3.52). At this time the
flow divider SHOULD engage itself
and give hydraulic power to the
proportional valve. The arm can now
work manually with the levers on
the proportional valve (figure #3.53).
• In the case when a roller cart is
stuck in the grabber, bring down
the cart to release it. Retract the
arm and the grabber inside the
hopper.
• Close the hopper door and drive the
vehicle to the maintenance facility
for repair.
