FUNCTIONAL OVERVIEW
Hopper System
A hopper mounted on the front of the machine is used to collect debris. A litter door is located on the front of the hopper to allow the
operator to throw large debris that cannot be swept into the hopper. The hopper broom opening has a dump door that is open when
sweeping and closed when raising the hopper. A hydraulic cylinder is used to open and close the dump door. A larger cylinder is used
to raise and lower the hopper. The back gear pump of the auxiliary pump runs the two cylinders. The hydraulic oil flows through the
priority divider to a directional control valve. The directional control valve has two switches built into it, the hopper switch (S15) and the
dump door switch (S16). When the dump door lever is moved to either the open or closed position, (S16) will energize the directional
by-pass solenoid (L1) and allow oil flow to the directional control valve. When the hopper lever is moved to the up position (S15) will
energize (L1) and oil will flow to the directional control valve. If the hopper lever is moved to the down position the interlock relay (K3)
will be energized and open the circuit to (S16) and not allow the dump door to be moved. The hopper/dump door interlock switch (S12)
will open when the dump door is closed or the hopper is up, de-energizing the door indicator light relay (K6) and opening the circuit to
the broom switches. The relief valve for the hopper hydraulic system is located in the directional control valve and is set to open at 2400
PSI.
