Squeegee System
Functional Description
Overview
The squeegee system includes the squeegee tool and the squeegee lift actuator.

Squeegee System Wiring Diagram
Circuit Description
The Squeegee Actuator M3 gets voltage from the A2 Control Board Assembly which switches the polarity to
move the squeegee tool up or down. When the A2 Control Board Assembly receives a signal from the A3 Switch/
Display Panel Assembly
via the CAN BUS that the operator has pressed the scrub on switch, the A2 Control
Board Assembly
sends the appropriate voltage to the Squeegee Actuator M3 to lower the squeegee to the
operating position.
