Control Panel
Switch and Button Functions
The controls on your rider scrubber were designed with one-touch operation in mind. For single-pass
scrubbing, the user can simply depress one switch and all systems on will be activated. For most single-pass
scrubbing operations, the operator should only need to use the middle switches on the control panel. These
are the red Scrub Off and the green Scrub On/Pressure Increase Switches.

Switch
• Key Switch – main power switch; controls the battery input to the machine’s main control board and the
wheel drive speed control.
• Scrub On/Pressure Increase Switch – functions as follows:
If the scrub system is off, pressing this switch once will put the machine into the Auto Scrub mode. The
following will occur:
– The scrub system will be enabled with the scrub pressure set to the #1 normal setting.
Note: Press the switch twice for #2 heavy scrub setting, and three times for the #3 extreme scrub
setting. Pressing the switch a fourth time will return the system to the normal scrub setting.
– The scrub deck and squeegee will automatically be lowered. On cylindrical models equipped with side
brooms, the side brooms will be lowered.
– The vacuum system will be enabled.
– The solution and detergent systems will be enabled. Note that both the solution and detergent ow
rates will correspond to the selected scrub pressure mode.
– As soon as the drive pedal is moved from its neutral position, the scrub brushes and side brooms (if
installed) will start turning, and the solution, detergent and vacuum systems will switch on.
™
General Information 22Service Manual – SC6500
◦ If the direction is forward, the solution and detergent ow will also start automatically.
◦ If the direction is reverse, the solution and detergent ow will be stopped and the squeegee will be
raised just enough to clear the oor surface.
Note: The solution, vacuum and detergent systems are automatically enabled when the Scrub On
Switch
is pressed to put the machine into the Auto Scrub mode. Any individual system can
be toggled off and on by simply pressing the corresponding system switch at any time during
scrubbing.
If the machine is already scrubbing, pressing the Scrub On/Pressure Increase Switch will increase the
scrub pressure to the next higher setting (toggling from regular to heavy, heavy to extreme, then back to
normal). The Scrub Pressure Indicator will show the selected scrub pressure (one, two or three bars) in the
Control Panel Display.
• Scrub Off Switch – Pressing this switch when the machine is in the scrub mode will cause the following to
occur:
– The scrub brushes will turn off and the scrub deck will be raised to the up position. On cylindrical
models equipped with side brooms, the side brooms will shut off and be raised.
– The solution and detergent ow will be stopped.
– Once forward machine motion stops, the vacuum/wand switch indicator light will start to blink. After
a user-programmable time delay, the squeegee will be raised and the vacuum motors will shut off.
Pressing the switch a second time before the vacuum time delay is complete will raise the squeegee
and turn off the vacuum motors immediately.
• Solution Switch – functions as follows:
– If the scrub system is off, pressing and holding this switch will switch on the solution ow to pre-
wet the oor. The solution ow will stop when the switch is released. Note this must be done prior to
pressing the Scrub On Switch and putting the machine into the Auto Scrub mode.
– If the machine is in the Auto Scrub mode, pressing this switch will disable the solution system. This is
used if you wish to scrub without adding additional solution to the oor.
– If the machine is in the Auto Scrub mode, you can press and hold the Solution Switch to actuate the
solution ow override function. This override function allows you to select a different solution ow rate
without changing the scrub pressure. Note that the machine is programmed for two additional higher
solution ow rates plus the three normal default ow rates, for a total of ve solution ow rates.
To actuate the solution ow override function, press and hold the Solution Switch for three seconds until
the Solution System Indicator ashes, then release it. You’ll have three seconds to select the desired
solution ow rate by pressing the Solution Switch. The Solution Flow Indicator will show the selected
solution ow rate (one through ve bars) in the Control Panel Display. Note that if any scrub pressure
change is made while in the solution override mode, the solution ow will return to its default solution
ow rate.
• Detergent Switch – functions as follows:
– If the solution system is enabled, pressing this switch will toggle the detergent system off and on.
When the detergent system is on, the detergent pumps will be activated at a specic rate when the
drive pedal is actuated. The detergent pump will turn off when the drive pedal is in neutral or reverse.
™
General Information 23Service Manual – SC6500
– If the solution system is off, the detergent pump will not turn on.
• Vacuum/Wand Switch – functions as follows:
– If the machine is in the Auto Scrub mode, pressing this switch once will raise the squeegee. The
vacuum motors will run for a short time delay, then shut off. If you press the switch twice, the vacuum
motors will shut off immediately. This is used if you wish to double-scrub (scrub without recovering the
solution).
– If the scrub system is off, the Vacuum/Wand Switch functions differently depending on whether the
seat switch is open (no operator in the seat) or closed (operator in the seat).
◦ If the operator is in the seat, pressing the switch will lower the squeegee and switch on the vacuum
motors. When the machine is moved into reverse, the squeegee will be raised, then lowered when
the machine is again moved forward. This mode is used to pickup water from the oor without
scrubbing or adding solution.
◦ If the operator is not in the seat, pressing the switch will toggle the vacuum motors on and off
to allow use of the vacuum wand. In this mode, the squeegee will not move up or down and the
recovery tank full indicator is ignored.
• Scrub Speed Switch – When the machine is operating in any one of its scrub settings, the machine’s travel
speed is reduced to 80 percent of the maximum transport speed pre-programmed into the speed controller.
Pressing the Scrub Speed Switch overrides the 80 percent of transport speed limit and increases the scrub
speed to 100 percent of transport speed.
• Traction Control Switch – regulates the drive wheel motor torque to minimize drive wheel slippage in
limited traction conditions.
• Side Broom On/Down Switch – lowers and raises the side brooms (only functional on cylindrical models
equipped with side brooms). Note that when the scrub system is switched on, the side brooms are lowered
to the same position they were in when the scrub system was last turned off (auto memory operating
position).
Note: You can raise or lower the side broom height to maintain the correct broom contact patterns
and compensate for normal broom wear. Refer to the Sweep System, Side Broom section for
instructions on setting the side broom height.
• Burst of Power Button – The Burst of Power Button functions differently depending on whether the EcoFlex™
mode is set to Mode 1 or Mode 2. (Also refer to the Control System/Main Programming Options/
EcoFlex™ Mode Selection section.) Note that in Mode 1 the detergent concentration is displayed as a
ratio. In Mode 2 the detergent concentration is displayed as a percent.
– In EcoFlex™ Mode 1, the minimum detergent concentration is displayed as a ratio. Pressing the Burst of
Power Button
in Mode 1 will do the following:
◦ The detergent ratio will change to the maximum concentration programmed ratio. (Also refer to the
Solution System/Maintenance and Adjustments/To Program the Detergent Ratio section.)
◦ The scrub pressure will increase to the next highest pressure.
◦ The solution ow rate will increase to the next highest level.
After 60 seconds, or after you press the Burst of Power Button again, the detergent ratio will revert
to the minimum concentration ratio, and the scrub pressure and solution rate will return to their
previous settings.
™
General Information 24Service Manual – SC6500
– In EcoFlex™ Mode 2, the minimum detergent concentration is displayed as a percent.. Pressing the
Burst of Power Button in Mode 2 will do the following:
◦ The detergent ratio will change to the maximum concentration programmed percentage. (Also refer
to the Solution System/Maintenance and Adjustments/To Program the Detergent Ratio section.)
◦ The scrub pressure will increase to the next highest pressure.
◦ The solution ow rate will increase to the next highest level.
After 60 seconds, or after you press the EcoFlex
™
Button again, the detergent ratio will revert to the
programmed ratio, and the scrub pressure and solution rate will return to their previous settings.
• Horn Button – sounds the horn when pressed.
• Control Panel Display – displays the various icons that indicate scrub pressure, solution ow rate,
detergent ratio, battery charge state and a recovery tank full condition. The display also shows any error
conditions detected by the main control board.
Control Panel Indicators
In general the following guidelines apply to the control panel indicators:
• When the key switch is rst turned on all of the blue or green control panel indicator lights will turn on
for one second for an operational test.
• A light indicator means that a system is on and running, or has been enabled and is ready to switch on
when the drive pedal is moved into forward or reverse.
• The indicators will be off when the system is disabled or switched off.
