Control Panel – SC750 ST and SC800 ST (Toggle Switch Control Panel)
These machines use a control panel with 3 large toggle switches and do not have an LCD display. See the following sec-
ons for switch idencaon and Indicator Light explanaons.
Switch Identification
• Key Switch (Main Power) - Turns “ON” the power to the control panel. “O” is “OFF” and “I” is “ON”.
• Soluon Switch (Low, Medium & High) – Pressing the switch forward turns on or increases the ow of cleaning
soluon to the oor. Pressing the switch backward turns o or decreases the ow of cleaning soluon to the
oor.(Note: Soluon will not ow unl the machine begins to move.)
• Vacuum/Wand Switch – Pressing the switch forward turns on the vacuum motor. Pressing the switch backward
turns the vacuum motor o.
• Scrub Switch
o Cylindrical Models – Pressing the switch forward lowers the scrub deck and enables all scrub funcons.
Pressing the switch backward disables all scrub funcons and raises the scrub deck.
o Disc Models – When rst pressed forward all scrub funcons are enabled. If in the normal scrub pres-
sure mode already, pressing the switch forward will extend the deck actuator to the “extreme” scrub
pressure mode which also increases the soluon ow. When operang in the extreme scrub pressure
mode, pressing the switch backward will retract the deck actuator to the normal scrub mode which also
decreases the soluon ow. When operang in the normal scrub pressure mode, pressing the switch
backward disables all scrub funcons and raises the scrub deck.
