THE VARIABLE DUMP SWEEPING AND DUST CONTROL SYSTEMS - HOW THEY WORK
Variable Dump 7765 machines are equipped with a sweeping and dust control system. Figure 16 shows the highest position for the variable
dump.

The debris from sweeping is thrown into the hopper (Figure 17). The baffl e system that is built into the variable dump debris hopper is designed to
minimize dust in the air while the machine is sweeping. The impeller vacuum fan pulls the lighter dust up and through a baffl e system. The Pre-
Clean Flap separates the heavier dust particles to an area below the fi lters. The dust fi lters capture the lighter dust particles. This allows the dust
fi lters to remain cleaner and need less shaking to remove dust. When the dust fi lters become clogged the fi lter shaker switch should be pushed to
start the dust shaker cycle. This will extend the life of the fi lters.
