CONTROLS 1. KEY SWITCH Controls the power for the machine functions. To turn the machine power on, rotate key clockwise. When the key is turned on the battery symbol will flash for 12 seconds while the system runs self- diagnostics and returns scrub deck and squeegee to raised position, if necessary. The controller will not respond to other commands until this routine is complete.

CONTROLS 3. ONE TOUCH SWITCH This switch controls the scrub brushes and vacuum all in one touch. To start scrubbing, press the one touch switch. The brush drive motors will turn on, the scrub deck will lower to the “light scrub” position, the solution will flow at “two bars”...
Page 16
CONTROLS 5. SOLUTION CONTROL SWITCH This switch controls the amount of solution flow to the scrub deck. There are 5 different flow settings. To increase the solution flow, press the solution control switch (+). To decrease solution flow, press the top of the switch (-). If the brush motors are turned off or the direction control lever is in neutral, the flow is automatically interrupted until the motors are turned on again, or the drive pedal is moved forward or reverse.

CONTROLS 7. DISPLAY TOGGLE SWITCH The display toggle switch allows you to change the information display screen. Two screens are available. • INFORMATION DISPLAY –SCREEN 1 • INFORMATION DISPLAY –SCREEN 2 • The hour meter is viewed on screen 2 of the information display. Hours are displayed for key ON time, brush run time, and traction motor time.
