HYDRAULIC OPENING POSITION SWITCHES
Both the Upper Chamber/Hopper and the Screen Cradle have switches to assure proper closing positions.
These switch locations are set at the factory and should not require adjustment. When operating properly,
the hydraulic pump will shutoff as the Upper Chamber/Hopper or the Screen Cradle reach their full
closed position.
If in these modes of operation the pump motor continues to run, the unit should be shutdown and
maintenance called to troubleshoot the operation.
Several factors could cause this situation. Positioning of switches, function of the switches or other
mechanical/electrical issues. The limit switches are mounted on adjustable plates. Adjust the plate so that
the switch is activated just as either the Upper Chamber/Hopper Screen Cradle reaches their full closed
positions (see Part Identification Drawing 348070). An electrician should perform all testing.
See drawing nos. 348070, 348185 and 1554-460 in rear of this manual.
HYDRAULIC PUMP OPERATION
The setting on the hydraulic pump assembly is set at the factory for the specific application that they
were originally intended. No changes should be made to the setting without consulting the factory.
