Control Panel Switch Functions

Key Switch (A)
Main power switch
Detergent System Switch (B)
This switch controls the on-board chemical mixing (detergent) system.
• Pressing and releasing this switch while the solution system is active will toggle the detergent system on and off.
• The Chemical Mixing System Indicator (D1) informs the operator when the detergent bottle is low. Pressing and
holding the Detergent System Switch (B) for two seconds after the detergent bottle has been refilled will reset the
Chemical Mixing System Indicator (D1) on the display to show full.
• Holding the Detergent System Switch (B) and the Solution/Pre-spray Switch (C) at the same time for two seconds will
switch the machine into the purge mode.
Solution/Pre-spray Switch (C)
If the scrub system is off, pressing this switch will cause the machine to enter fast pre-spray mode. The following will
occur:
• The scrub system will be enabled with the system configured for fast pre-spray mode, and the scrub deck will be
lowered while the extraction/vacuum shoes stay up in the locked position.
• The solution system will be enabled for fast pre-spray mode.
• The detergent system will be enabled for pre-spray mode.
• The travel speed will be limited to a fast pre-spray mode speed setting.
• As soon as the throttle is moved from the neutral position the scrub brushes will start turning. If the direction is
forward, the solution and detergent flow will start. If the direction is reverse, the solution and detergent flow will be
stopped.
• The Fast Pre-spray Mode indicator (D7) will indicate the scrub system is activated in fast pre-spray mode.
• The Scrub ON Switch (J), Solution Pre-spray Switch (C) and Detergent System Switch (B) will be green if the scrub
system is on and the fast pre-spray mode has been selected. The indicators will be off if the scrub system is off. The
indicators will be yellow if the pre-spray mode has been selected but the throttle is in neutral.
• Pressing the Scrub ON Switch (J) in the fast pre-spray mode switches the machine to the heavy pre-spray mode.
In this mode the machine moves slower and more solution is sprayed on the carpet. The Heavy Pre-spray Mode
indicator (D8) will indicate that the scrub system is in heavy pre-spray mode.
If the pre-spray mode is active, pressing this switch will cause the following to occur:
• The scrub brushes will turn off and the scrub deck will rise to the up position.
• The solution flow will be stopped.
• The detergent flow will be stopped.
• The travel speed limit will return to the transport speed setting.
• The display will indicate the nozzles are turned off and the deck is in the raised position.
• The scrub off indicator will be green if the scrub system is off and ready to be activated. The indicator will be off if
the scrub system has been activated. If the scrub system has been turned off and the scrub deck is not up yet, the
indicator will be red. If there is a fault in the scrub system, this indicator will flash red.
