Tank
The main component of the chassis system is the solution tank, to which the rest of the machine components
attach. The recovery tank is connected to the solution tank with a hinge so that it may be opened to access
the battery compartment of the machine. The front nose is attached to the solution tank with 4 lift-off studs
for access to the scrub deck components. The front nose on a basic machine (Warrior ST) is a one-piece
component. For machines with detergent systems (Warrior AXP and EcoFlex), the front nose contains a
hinged detergent cover for accessing the detergent bottle.
Front Nose Removal
To remove the front nose, lift it up until the studs are clear of the keyhole slots, and pull it away from the
machine. To replace the front nose, insert all 4 studs through the keyhole slots and press the nose down
until locked in place.

Control SystemService Manual – Warrior ST, AXP, EcoFlex 15
Control System
Functional Description
Within the Warrior system there are two primary controllers: the Warrior Controller (A1) and the Curtis
Drive controller (A2). The Warrior controller controls the primary machine functions, and the Curtis
controller controls the drive functions. The Curtis controller communicates with the Warrior controller to
inform the Warrior controller of machine movement status.
Control Panel
There are three versions of the main control
panel depending on the machine type: ST, AXP,
and EcoFlex. The functions of the control panel
are similar for each model, and are shown to
the right and summarized below. (Also see the
Control Panel Indicators section for descriptions
of the various indicator lights and displays.) The
control panel is an integral component with the
Warrior controller (A1) circuit board.
Key Switch (A): The keyswitch serves as
a main control switch to enable or disable
operation of the machine. The key is removable
to prevent unwanted operation when not in use.
The keyswitch doesn’t disconnect any power
circuits, but instead, sends a signal to both the
Warrior controller and Curtis Drive controller to
indicate the On/Off function.
Solution Switch (B): This switch turns the
solution system on, off, or change the solution
rate (regular, heavy, extreme). The solution
ow will turn on only when the throttle is
moved from the neutral position in the forward
direction. The solution ow will turn off if
the throttle returns to neutral or is moved to
reverse. Pressing this switch when the scrub
system is off will momentarily turn the solution
ow on to allow pre-wetting of the scrub
brushes.
Vacuum Switch (C): This switch is used
to turn the vacuum system on or off. Pressing
this switch will alternate between on and off.
The vacuum will only turn on when the throttle is moved from the neutral position. It will remain on for 10
seconds after the throttle returns to neutral. The vacuum also has an automatic shutoff feature that will
turn the vacuum and scrub systems off if the recovery tank becomes full.
Scrub ON Switch (D): If the scrub system is off, pressing this switch once will cause the following:
• The scrub system will be enabled with the scrub pressure set to the regular setting and the scrub deck
will be lowered. Note: press twice for the heavy scrub pressure mode and hold this switch for 5 seconds to
enter the extreme scrub mode.
• The vacuum system and solution system will be enabled.
• As soon as the throttle (operator drive paddle) is moved from the neutral position the scrub brushes will
start turning and the vacuum will turn on. If the direction is forward the solution ow will start. If the
direction is reverse, the solution ow will be stopped. If the scrub system is already enabled when this
switch is pressed, the scrub pressure will increase to the heavy scrub mode. If the switch is held for 5

seconds the pressure will change to the extreme scrub mode. At the same time the panel display will show
the correct changed scrub pressure setting.
Scrub OFF Switch (E): Pressing this switch when the unit is in a scrub mode will cause the following:
• The scrub brushes will turn off. the scrub deck will be raised to the up position, and the solution ow will
be stopped
• The rst time that this switch is pressed, the vacuum system will NOT be turned off. This is so that any
remaining water may be picked up without having to turn the vacuum back on. If this switch is pressed
a second time (pressed after the scrub system has been turned off) the vacuum will shut off after a 10
second delay.
Wand Switch (F): This switch is used when an external vacuum/scrub wand is used. Pressing this switch
will turn the vacuum on continuously without regard to the throttle position. If the scrub system was on it
will be turned off. This includes turning off the scrub brushes and turning the solution ow off (to the scrub
deck). Note: automatic shutoff of the vacuum motor when the recovery tank is full is disabled when
the wand is enabled.
Extended Scrub (Recycle) Switch (G): Extended Scrub is available only on Warrior ST and AXP
models. Pressing this switch will turn on or off the extended scrub option. When extended scrub is active,
a portion of the solution to the scrub deck will come from the recovery tank. By recycling some of the used
solution with some new solution, the overall scrubbing time of the machine can be extended before relling
the solution tank or emptying the recovery tank. See the main programming options in this manual to select
(activate) the recycle option. Purge Function: To prevent buildup of debris in the recycling lines and pump,
the system should be purged after use. Drain the recovery tank and ll with clean water, and then push and
hold the extended scrub switch for 3 seconds to initiate the purge function. The purge will run for 20 seconds
to ush the lines. Note: Failure to purge the recycle system after use may cause the extended scrub
pump and/or solenoid valve to become fouled.
Chemical Switch (H): The chemical (detergent mixing) option is available only on Warrior AXP and
EcoFlex models. Pressing this switch will turn on or off the chemical option. When active, a small pump
will inject chemical (detergent) into the solution line upstream from the scrub deck. The chemical pump
is disabled any time the solution system is inactive. See the main programming options in this manual to
select (activate) the onboard chemical distribution system.
EcoFlex Switch (I): This option is available only on EcoFlex models. By default, the EcoFlex cleaning
mode is active during normal operation to conserve solution and detergent. Press this switch for 2 seconds
to override the EcoFlex cleaning mode and temporarily increase scrub pressure, solution ow, and the
detergent ratio. See the main programming options in this manual to select (activate) the EcoFlex option.
Control Panel Indicators
Each of the switches on the control panel have an indicator LED adjacent to the switch. Most LEDs are
dual channel and provide two colors within the same LED. In general, the following guidelines apply to the
control panel indicators, and various exceptions to this rule are listed separately:
A steady green indicator means that the particular system or function is on.
A ashing green indicator means that the particular system is in a delayed-off condition. An example of
this is when a scrub mode is selected and the throttle goes from forward or reverse to neutral. When this
happens the vacuum indicator will ash green indicating that the vacuum is still on but that it will be
turning off after the delay period.
A steady yellow indicator means that the particular function has been enabled and in a ready state, but
is not currently on. For example, if a scrub mode is selected and the throttle is in neutral, the scrub system,
vacuum, and solution indicators will all be yellow indicating that the systems are enabled and ready to turn
on when the throttle is moved to forward and/or reverse.
A ashing yellow indicator means that a fault has occurred in the particular system. An example of this
would be an over-current fault on one of the motors.

Control SystemService Manual – Warrior ST, AXP, EcoFlex 17
Scrub ON Indicators (L & M):
• For Regular scrub mode, the (L) LED will be active.
• For Heavy scrub mode, the (M) LED will be active.
• For Extreme scrub mode, both (L&M) LED’s will be active.
• When a scrub mode (regular, heavy, or extreme) is active and the drive
paddle is in the neutral position, the LED’s (L and/or M) will be solid yellow.
• When a scrub mode (regular, heavy, or extreme) is active and the drive paddle is in the drive position, the
LED’s (L and/or M) will be solid green.
• Both indicators will be off if the scrub system has been turned off.
Scrub OFF Indicator (N):
• This indicator has green and red colors.
• The indicator will be green if the scrub system is off and ready to be activated.
• The indicator will be red if the scrub system has been turned off and the scrub deck is not up yet.
• The indicator will ash red if there is a fault in the scrub system.
• The indicator will be off if the scrub system has been activated.
Wand Switch (F) Indicator:
• This indicator uses green color only.
• This indicator will be green if the Wand Switch has been turned ON.
• This indicator will be off if the Wand Switch has been turned OFF.
• This indicator is also the Status LED indicator, and will ash green with an error code from the Curtis
Drive controller (See the Wheel System, Traction chapter for details).
Vacuum Switch (C) Indicator:

Scrub Mode Indicators
The Solution system and Scrub system have three scrub
modes (regular, heavy, and extreme). These scrub modes
are jointly controlled when the Scrub On Switch (D)
is pressed, but the Solution system can be controlled
separately by pressing the Solution Switch (B).
• Pressing the Scrub On Switch (D) once will set both the
scrub mode and solution mode to regular (and clear any
solution system overrides).
• Pressing the Scrub On Switch (D) twice will set both the
scrub mode and solution mode to heavy (and clear any
solution system overrides).
• Pressing the Scrub On Switch (D) for 5 seconds will set
both the scrub mode and solution mode to extreme (and
clear any solution system overrides).
• Pressing the Solution Switch (B) once, twice, or for 5
seconds; will change the solution mode accordingly, but
without changing the scrub mode.
Warrior ST Display: The solution mode is displayed in
a bar graph adjacent to the solution switch (B), and the
scrub mode is indicated in the display (K) with a number
representing the mode.
(1 = regular, 2 = heavy, 3 = extreme).
Warrior AXP and EcoFlex Display: The solution mode
and scrub mode are both shown in bar graphs on the main
display (O).
Battery Indicator
The charge state of the battery is shown in the main display area of the
control panel. For Warrior ST models, this is indicated by three colored
LED’s (P). For Warrior AXP and EcoFlex models, this is shown with a bar
graph (Q) in the main display. For AXP and EcoFlex models, when the
battery is depleated and needs to be charges, the charge indicator (R) will
be displayed.
Also note that for AXP and EcoFlex models,
when in Service Mode, the actual battery
voltage will be displayed numerically in the
lower left corner of the main display.
Warrior Controller
The Warrior controller (A1), which includes the
control board and the display, is the primary
electronic control for the Warrior machine and its
functions (except drive control). The control board is
the basic input/output device and contains a micro-
contoller chip to regulate function. The controller
receives and interprets user inputs, sensor inputs,
and even some motor amperage readings, and
controls device output for the user display, solenoid
operation, and motor control. Most low and medium
power outputs are controlled with power MOSFET

transistors, with some moderately high power devices controlled with micro-relays, and very high power
devices (vacuum and brush motors) controlled with external motor contactors.
Another function of the main controller is to detect any system failures and display an error code on the
display panel or store it in the main control board’s memory. The error code(s) are used to help the service
person determine the fault and to quickly guide in repairing a specic system malfunction. Note: See the
Troubleshooting Guide for further information. An additional special feature of the main control board is
to change program settings for a set of specic machine functions. See the Main Control Board Programing
section in this chapter for further information.
Main Control Board Programming
The Warrior controller is programmable for machine specic functions and parameters. This is a required
task when replacing the controller with a new controller. The table below and following sections describe the
parameters to be programmed.

Displaying the Control Board Revision Level
During machine service, it may be helpful to know the control board revision level to determine machine
conguration. To view the control board revision level:
AXP & EcoFlex Models:
1. Turn the key switch to the off position.
2. While holding the Scrub Off (E) and Chemical (H) switches depressed, turn on
the key switch.
3. Hold both switches until Scrub Off and Chemical indicators turn green.
4. The display will show the revision level (letter) of the control unit. Chemical
indicator will blink in revision display mode.
5. To exit this mode, turn the main power key switch to the off position.
ST models:
1. Turn the key switch to the off position.
2. While holding the Scrub Off (E) and Wand (F) switches depressed, turn on the
key switch.
3. Hold both switches until Scrub Off and Wand indicators turn green.
4. The LED display will show the revision level (letter) of the controller software.
5. To exit the revision level recall mode, turn the key switch to the off position.
Recall of Stored Error Codes
To assist with service troubleshooting, the Warrior controller maintains a list of past error codes. To recall
and/or clear the stored error codes perform the following steps:
1. Turn the key switch to the off position.
2. While holding the Solution Switch (B) depressed, turn the key switch to the on position.
3. Continue to hold the solution switch until the solution indicator turns green.
• On AXP/EcoFlex models:
◦ If there are no error codes stored, the display will show the key switch icon.
◦ If any error codes are stored, the display will show the wrench icon and error number right next to
the wrench. If more than one error code is stored, it will cycle through all the error codes stored.
• On ST models:
◦ If there are no error codes stored, the display will show “—”.
◦If any error codes are stored, the scrub off indicator will be red and the display will show the error
code number(s). If more than one error code is stored, the display will scroll through the error
codes in sequence.
4. To clear the stored codes, press the scrub off switch. (It is recommended that error codes are cleared
after servicing so that future error codes represent only errors that occur between service intervals.)
• On AXP/EcoFlex models, the display will now show the key switch icon.
• On ST models, the display will now show “—”.
7 To exit the error code recall mode, turn the key switch to the off position.
