This machine is equipped with two Emergency
Stop buttons, one on the control panel and one
on the back of the recovery tank cover. Use the
Emergency Stop buttons only in emergency
situations, as solution could be potentially released
from the squeegee vacuum hose and onto the
floor, creating a slipping hazard.
NOTE: These buttons should not be used for
normal stopping, as premature wear to the parking
brake and/or drive system may occur.
Press either Emergency Stop button in an
emergency to halt the machine power.
Immediately after either Emergency Stop button
is pushed the Emergency Stop Button Pressed
screen will appear on the UI touchscreen. Follow
the instructions on the UI touchscreen.
Twist the Emergency Stop button used to stop the
machine clockwise to disengage the emergency
stop function. The Emergency Stop Button
Released screen appears on the UI touchscreen
immediately after the Emergency Stop button is
disengaged. Touch CONFIRM.
If the Emergency Stop button was pressed when
the machine was on a robotic route, press the
blue start/pause button to resume scrubbing in
the robotic mode. As the machine begins robotic
operation, observe scrubbing performance to
ensure that all components are functioning
properly.
If the Emergency Stop button was pressed when
the machine was in the manual mode or when
teaching a new route, press the 1-Step button and
resume operating the machine in the manual mode
or teaching the new route.
NOTE: When teaching the machine, the 1-Step
button must be pressed before beginning to teach
the machine after the Emergency Stop button is
disengaged. The 1-Step button is automatically
turned off when the Emergency Stop button is
engaged and must be turned back on to continue
teaching the machine.

MACHINE HOUR METER
The hour meter records the number of hours the
machine has been operated. This information is
useful for servicing the machine. The hour meter is
located underneath the operator seat and next to
the circuit breakers.
ec-H2O SYSTEM INDICATOR LIGHT
NOTE: The ec-H2O system indicator light will not
illuminate until the machine starts scrubbing.

If the ec-H2O system indicator light begins to
blink green/red, the water conditioning cartridge
needs to be replaced (See ec-H2O WATER
CONDITIONING CARTRIDGE REPLACEMENT).
*Verify if cleaning detergent was added to solution
tank. If ec-H2O system was operated with cleaning
detergent, drain solution tank, add clear water and
operate the ec-H2O system until the indicator light
code clears.
BLUE START/PAUSE BUTTON
The machine is equipped with a blue start/pause
button on the back that is used to start a robotic
route or pause an in-process robotic route. When
a saved navigation route is selected on the UI
touchscreen, the blue start/pause button flashes.
When pressed to start the route in robotic mode,
the blue start/pause button stops flashing and
remains consistently illuminated during robotic
operation. The blue start/pause button is off when
operating the machine in manual mode.
When a saved navigation route is selected on the
UI touchscreen, press the flashing blue start/pause
button to begin running the route in robotic mode.
If necessary, approach the machine from behind
and press the blue start/pause button again to
pause the in-process robotic route. The machine
stops moving forward and the scrub brush stops
rotating. The vacuum remains on for a short time
to pick up remaining solution and then turns off.
The machine can be driven manually when a
robotic route is paused. This may be necessary
if there is an obstacle that the machine is unable
to maneuver around on its own. The navigation
software will keep track of the current machine
location within the route and allows the route to be
resumed. Press the blue start/pause button again
to resume the robotic route.
