Optional High-pressure Spray System (LP and Diesel Only)
The optional high-pressure spray system
uses a separate pump, driven by the
engine via a clutch, to pump solution
at high pressure from the tank to the
hose and wand. The high-pressure spray
system operates independently and has its
own separate lter/strainer, and supply
and return ports on the solution tank.
Solution Level Sensor
The solution level sensor is a pressure sensor contained directly on the Main Machine controller circuit
board. A exible tube transmits the pressure of the water in the solution tank (called the head pressure) to
the sensor on the control board.
If the solution level has been low longer than 10 seconds, the LCD display will show the solution level low
caution icon. The conditions under which the solution level low icon is displayed depend on the state of the
extended scrub system as follows:
• With the extended scrub system off:
– If the clean solution is low, the solution level low icon will be displayed.
– If the clean solution is not low, the solution level low icon will not be displayed.
• With the extended scrub system on:
– If the extended scrub solution level in the recovery tank is not low, the solution level low icon will not
be displayed.
– If the extended scrub solution level is low but the clean solution level is not low, the solution level low
icon will not be displayed.
– If both the extended scrub and clean solution levels are low, the solution level low icon will be
displayed.
