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 the machine will be ready to go. 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.

• 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 Information15Service Manual – Condor™ EcoFlex™, BR 1100/1300 EcoFlex
◦ 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 use 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.
– If the solution system is off, the detergent pump will not turn on.
™
General Information16Service Manual – Condor™ EcoFlex™, BR 1100/1300 EcoFlex
• 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 and
provide better traction.
• 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.
• EcoFlex
™
Button – The EcoFlex™ 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 detergent ratio is preset to 1:400. Pressing the EcoFlex
™
Button in Mode 1 will
do the following:
◦ The detergent ratio will change to the 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 rate.
After 60 seconds, or after you press the EcoFlex
and the scrub pressure and solution rate will return to their previous settings.
™
Button again, the detergent ratio will revert to 1:400,
™
General Information17Service Manual – Condor™ EcoFlex™, BR 1100/1300 EcoFlex
– In EcoFlex™ Mode 2, the default detergent ratio will be the programmed ratio. Pressing the EcoFlex
Button
in Mode 2 will do the following:
◦ The detergent concentration will change to the next highest (richest) concentration. For example,
if the programmed concentration is 0.4%, pressing the EcoFlex
™
Button will change it to 0.5%. (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 rate.
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 control panel indicator lights will turn on for one
second for an operational test.
• A blue 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.
• The green EcoFlex
™
Indicator will be on when the system is in the low-concentration mode, and ash when
the 60-second burst of power function is active.

The control system consists of the A2 Control Board Assembly, the A3 Switch/Display Panel Assembly and
associated sensors and circuitry.
A2 Control Board Assembly
The A2 Control Board Assembly, sometimes referred to the
main controller, communicates with the Curtis A1 Speed
Controller
and the A3 Switch/Display Panel Assembly to
coordinate the operation of the various machine systems.
The A2 Control Board Assembly is fastened to the Electrical
One primary function of the A2 Control Board Assembly is
to position the scrub brushes relative to the oor surface
using a lift actuator motor. The A2 Control Board Assembly
continuously monitors the brush motor current draw to
maintain the desired scrub pressure on the oor.
Curtis A1
Speed
Controller
• If the brush motor current drops below the desired
range, the A2 Control Board Assembly switches on the
lift actuator motor to move the scrub deck downward
until the brush motor current draw is within the
correct range for the scrub pressure selected.
• If the brush motor current rises above the desired
range, the A2 Control Board Assembly switches on the
lift actuator motor to lift the scrub deck upward until
the brush motor current draw is again within the
correct range for the scrub pressure selected.
Note: Refer to the Scrub System section in this
manual for a complete explanation of
scrub deck operation.
A secondary function of the A2 Control Board Assembly is to detect any system failures and display the
corresponding error code on the display panel, or store it in the control board’s recall memory mode. The
error codes are used to help service technicians determine the fault and to guide in repairing a specic
system malfunction quickly.
Note: See the Troubleshooting section for further information.
The A2 Control Board Assembly also allows you to change program settings for a set of specic machine
functions. See the Main Control Programming Options section in this manual for further information.
A3 Switch/Display Panel Assembly
The A3 Switch/Display Panel Assembly is the user
interface that includes the various system switches and
buttons, and the control panel display. The A3 Switch/
Display Panel Assembly sends the operator inputs via a
CAN BUS to the A2 Control Board Assembly.

Circuit Description
The A2 Control Board Assembly is connected by several inputs to battery negative:
The A2 Control Board Assembly gets positive battery voltage from two inputs:
• When the key switch, seat switch and battery interlock are closed, positive voltage is supplied to the A2
Control Board Assembly.
• When the key switch is closed, positive voltage is supplied to the coil side of contactor K5. When K5
contacts close, positive voltage is supplied to the A2 Control Board Assembly.
The A3 Switch/Display Panel Assembly gets voltage from two outputs on the A2 Control Board Assembly.
The A3 Switch/Display Panel Assembly communicates with the A2 Control Board Assembly via a CAN BUS
connection (CAN H and CAN L).

* The signal controlling the detergent pump is extremely complex and eld troubleshooting should a take a functional approach. Substitute with a known
good detergent pump to check operation. If the known good pump does not operate, and the wiring and control inputs to the EcoFlex™ system is
correct, the EcoFlex™ system is probably defective. Check the resistance of the detergent pump before replacing the EcoFlex™ system so as not to
damage it if the pump is defective.
** The Solution Pump (-) line provides a switched ground return for the pump. When the solution pump is on, a 5KHz signal with a varying duty cycle and
a peak voltage of 36 volts will appear between this pin and B+. Measuring with a DC voltmeter will give a signal in the range of 6 to 27 volts. Changing
the ow rate solution bars on the LCD should produce a relative increase or decrease of the meter reading.

Functional Description
Overview
This section includes information on battery installation and maintenance, a description of the low-voltage
cut-out function, and descriptions of the battery condition displays.
• For information on the A2 Control Board Assembly, refer to the Control System section.
• For information on the A1 (Curtis) Speed Controller, refer to the Wheel System, Traction section.
All models discussed in this manual are equipped with a low-voltage cutout feature to prevent overdischarging of the batteries. When a machine’s battery pack voltage falls below a specically dened
threshold (voltage settings), the scrub system automatically shuts down. The drive motor will still operate in
the low-voltage cut-out mode to allow the machine to be driven to a charging location.
The low-voltage cut-out level is adjustable. The standard lead-acid battery (wet cell) setting is 1.72 volts per
cell. The alternate maintenance-free battery (gel cell) setting is 1.81 volts per cell. The standard lead-acid
battery setting is factory-selected and should be used unless the battery manufacturer species the higher
cut-out voltage.
Service Note: A minimum recharge voltage of 2.13 volts per cell must be reached to allow the
scrub and solution systems to function again (reset). A 36-volt battery pack must
increase to a 38.6-volt minimum.
Battery Condition Indicator
The battery indicator displays the state of battery charge. Five vertical bars indicates a fully-charged
battery after a complete charging cycle. The battery indicator will retain the state-of-charge even if the key
switch has been turned off. The state-of-charge indicator is reset to full charge when the batteries have been
recharged. It is also possible to choose between two different low-voltage thresholds depending on whether
maintenance-free or standard (lead-acid) batteries are being used (Have a qualied service engineer perform
this selection*.)
Note: The following percentages are based on usable battery capacity, not total battery capacity.
Therefore, 100% discharge = 80% of total battery capacity for standard wet-cell batteries, or
70% of total battery capacity for maintenance-free batteries.
Warning! Before performing any machine maintenance or adjustments, make sure the key
switch is off and the key is removed from the machine.
Wet-cell Battery Maintenance
Correct maintenance of electric vehicle batteries can greatly extend their life. Well-maintained batteries may
last up to three years, but failure after one year is common if maintenance has been inadequate.
There are three simple rules for good battery maintenance:
• Maintain the correct electrolyte level (check weekly). Use distilled water in batteries whenever possible.
If batteries are discharged, add just enough water to cover the plates in each cell. If batteries are fully-
charged, ll each cell to the bottom of the ller tube. Do not overll the batteries! Do not add acid to
batteries!
• Keep the batteries charged (charge weekly). Batteries should be charged each time that a machine is
used for more than one hour. The battery compartment cover should be open during charging to avoid
a concentrated buildup of hydrogen gas. Operators should follow the instructions provided with their
specic battery charger to determine how long the batteries should be charged. Even when a machine is
stored, the batteries should be charged once a month to prevent the batteries from “sulfating”. Almost all
battery caps are vented, so there’s no need to loosen or remove them for charging.
• Keep the batteries clean (check and clean monthly). Use a damp cloth to wipe dirt from the top of the
batteries. Battery terminals must be clean and tight. If the tops of the batteries are wet after charging,
the batteries have probably been overlled or overcharged.
Note: If there is acid on the batteries, wash the tops of the batteries with a solution of two
tablespoons of baking soda to one quart/liter of water.
Caution! To avoid damage to floor surfaces, wipe water and acid from the top of the batteries
after charging.
Troubleshooting
Battery Testing
A battery problem is usually recognized by the machine operator as a decrease in the machine’s running
time. This condition is usually caused by one or more “dead cells” in the battery system – that is, one or more
cells that are putting out less voltage than the other cells.
Note: Always charge batteries before testing.
There are two ways to nd a dead cell:
• Use a voltmeter to check the voltage of each battery with the scrub and drive motors running. The battery
with the dead cell will read 1 or 2 volts lower than the other batteries in the system.
• Use a hydrometer to check the specic gravity
Approximate State of Charge Corresponding to
(or “state of charge”) of the uid in each cell. A
dead cell is one that reads 50 points (or more)
lower than the other cells.
State of ChargeSpecific Gravity
If the batteries in the machine are more than one
year old, it’s usually best to replace the whole set
rather than replacing just one battery.

Removal and Installation
Warning! Before removing or reinstalling any machine components, make sure the key switch
is off and the key is removed from the machine.
To Install the Batteries
Warning!
• Use extreme caution when working with batteries. Sulfuric acid in batteries can cause severe
injury if allowed to contact the skin or eyes.
• Explosive hydrogen gas is vented from the batteries through openings in the battery caps.
This gas can be ignited by any spark, flame or electrical arc. Do not install any lead-acid
battery in a sealed container or enclosure. Hydrogen gas from overcharging must be allowed
to escape.
• Electrical components in this machine can be severely damaged if the batteries are not
installed and connected correctly.
• The batteries must be installed only by an Advance representative or dealer, a qualified
electrician or the battery manufacturer.
1. Remove the batteries from their shipping crate and carefully inspect them for cracks or other damage. If
damage is evident, contact the carrier that delivered them, or the battery manufacturer, to le a damage
claim.
2. Turn the key switch off and remove the key.
3. Remove the recovery tank from the machine. (Refer to the Recovery System/Removal and Installation/
Recovery Tank section.)
4. Your machine comes from the factory
with enough battery cables to install
six 6-volt batteries. Using at least
two people and an appropriate lifting
Battery
Disconnect
strap, carefully lift the batteries into
the battery compartment and arrange
them exactly as shown. Secure the
batteries as close to the front of the
machine as possible. If installing a
monoblock battery, use an overhead
hoist.
5. Install the battery cables as shown.
Position the cables so the battery caps
can be removed easily for battery
service.
™
6. Carefully tighten the nut in each battery terminal until the terminal will not turn. Do not overtighten
the terminals or they will be very difcult to remove for future service.
7. Coat the terminals with spray-on battery terminal coating (available at most auto parts stores).
8. Put one of the black rubber boots over each of the terminals and connect the Battery Disconnect.
Use a combination of multiple 2-volt cell units to construct a 36-volt DC
battery pack system.
Wet Cell Batteries
Wet Cell Battery Charger
Advance-recommended battery pack capacity is a 395 AH @ 20 Hour Rate
deep cycle battery system. Note that the battery pack must t the battery
compartment size listed in the Technical Specifications.
Use a 36-volt DC output charger matching the DC battery pack voltage and
the input AC line voltage supply being used.
When selecting a battery charger always follow the recommendation of the
battery supplier to match the correct charger DC output amperage to the
amp-hour rating batteries being installed. This will prevent the battery pack
from being overcharged or undercharged.
The recommended 395 AH battery should be matched to a 36-volt, 36-amp
output charger on machines using six 6-volt batteries.
The optional 450 AH battery should be matched to the Advance 36-volt, 38amp output charger.
Special Tools
A hydrometer can be used to check the specic
gravity of the battery electrolyte. A typical example is
shown here.

Recovery System
Functional Description
Overview
The recovery system picks up the
scrubbing solution from the squeegee
tool and directs it to the Recovery Tank.
Recovery Tank
The Recovery Tank holds 70 gallons
[265 l] of wastewater and supports the
Vacuum Motor, Recovery Tank Lid and
Top Cover Assembly.
The Vacuum Motor switches on
automatically when the scrub system
is enabled and the machine moves
Drain
Hose
Squeegee
forward. The Vacuum Motor will switch
off after a predetermined time delay
once machine motion stops.
The Vacuum Motor can also be switched on independent of the scrub system by pressing the vacuum/wand
switch. This is used to pick up solution already on the oor, or when using a wand on the Squeegee Hose.
A current sensor monitors the Vacuum Motor current and will display a fault if the Vacuum Motor current
draw is too high.
Squeegee and Squeegee Hose
The wastewater and air enter the vacuum system at the Squeegee tool through small openings (notches)
located in the front Squeegee blade. The small openings are the entrance points for the water and air and
help speed up the airow, producing the suction to lift the wastewater off of the oor. The solution travels
through the Squeegee Hose at high speed and into the Recovery Tank. The airow continues through the
Recovery Tank, vacuum fan inlet screen and Vacuum Motor, then is exhausted out of the Vacuum Hose. No
wastewater ever actually moves through the Vacuum Motor, just the working air.
A shutoff Float Cage and Ball prevent the Recovery Tank from being overlled and stops any water from being
sucked into the Vacuum Motor. When the Float Ball rises (to full-tank level) it will seat itself inside the Cage
assembly and block off the Vacuum Motor airow. This causes a reduced Vacuum Motor current load which is
sensed by the A2 control board which automatically shuts off the vacuum and scrub systems.
The LCD will then display the recovery tank full indicator
icon to alert the operator that the recovery tank needs to
Vacuum Motors M5 and M6 get positive voltage from the Battery when the load sides of contactors K5 and K1
are closed. Contactors K5 and K1 close when the A2 Control Board Assembly connects the K5 and K1 contactor
coils to battery ground. Vacuum Motors M5 and M6 are connected directly to battery ground.
The A2 Control Board Assembly connects the K5 and K1 contactor coils to battery ground when:
• The A3 Switch/Display Panel Assembly sends the A2 Control Board Assembly a signal via the CAN BUS that
the vacuum system has been switched on, or,
• The A1 Speed Controller sends the A2 Control Board Assembly a signal that the wheel drive is switched on,
the scrub system is enabled and the vacuum system has not been switched off.
Note: The A2 Control Board Assembly monitors the voltage input from the Vacuum Motor Shunt
wire connected to the ground side of Vacuum Motors M5 and M6. If the voltage is out of the
acceptable range (.07 - .12 volts for a single vacuum motor or .15 - .24 volts for dual vacuum
motors), the A2 Control Board Assembly will sense that the oat ball is sealed against the oat
cage and that the recovery tank is full. The A2 Control Board Assembly will then shut down
the vacuum and scrub systems and display a recovery tank full icon on the LCD.

Scrub System, Cylindrical
Functional Description
Overview
The Condor EcoFlex™ cylindrical scrub deck models use two cylindrical brushes that counter-rotate to sweep
up light debris into a removable hopper, and scrub at the same time. The two scrub brushes are powered on
opposing ends by 1-1/2 HP permanent-magnet motors and drive belts.
The scrub deck actuator raises and lowers the scrub deck, and automatically adjusts the deck height while
The coil sides of contactors K2 and K3 get positive voltage from the Battery when the load side of contactor
K5 is closed. Contactor K5 closes when the A2 Control Board Assembly connects the K5 coil to battery ground.
Contactors K2 and K3 are connected to battery ground through the A2 Control Board Assembly.
The Right Brush Motor M9 and Left Brush Motor M10 get positive voltage from the Battery when the load sides of
contactors K2 and K3 are closed respectively. Contactors K2 and K3 close when the A2 Control Board Assembly
connects the K2 and K3 coils to battery ground. The Right Brush Motor M9 and Left Brush Motor M10 are
connected directly to battery ground.
The Brush Actuator M2 gets voltage from the A2 Control Board Assembly which switches the polarity to move the scrub deck up or down. When the A2 Control Board Assembly receives a signal from the A3 Switch/Display

position.
The Scrub Deck Sensing Resistor R2 senses the deck size so the operator does not need to program the deck
size into the hidden menu.
As the brush motor current passes through the BRN current sense wire, which is in effect a low-value
resistor, a small voltage drop is developed across it which is proportional to the motor current. This voltage
change is inputted to pin J2-2 on the A2 Control Board Assembly. Any surrounding temperature change in
the BRN current sense wire affects its resistance, so the temperature is sensed by a thermistor built into
the A2 Control Board Assembly. This allows error correction for the temperature resistance changes in the
BRN current sense wire. When A2 Control Board Assembly senses a current draw out of the desired range it
automatically turns on the M2 actuator motor to raise or lower the scrub deck. This process is ongoing in
maintaining the operator’s selected scrub motor current load setting to sustain the desired brush working
pressure.
via the CAN BUS that the operator has pressed the scrub on switch, the A2 Control Board
sends the appropriate voltage to the Brush Actuator M2 to lower the scrub deck to the operating

the brush deck is in the
lowered position, don’t
turn the key switch off
until you disconnect the
battery pack (push in the
Emergency Disconnect).
This will prevent
the scrub deck from
automatically rising
when the key is turned
off.
5. Loosen both worm Gear Clamps that fasten the inboard and outboard Motor Shrouds to the motor
housing, then remove both Motor Shrouds from the motor.
6. Remove the two hex nuts (10 mm socket) and Phillips screw holding the Belt Guard and remove the Belt
Guard
.
7. Remove the four motor mount Screws holding the Scrub Motor to its deck mount. Also note that the Scrub
Motor
may stick to the motor mount, so be careful and watch your ngers as the motor will drop.
8. Turn the Scrub Motor clockwise to access the motor terminal studs. Note the wire connections for correct
reassembly, then remove both motor wires.
9. Lower the deck assembly to the deck actuator’s maximum down position (travel) to get the clearance
needed to remove the motor from the machine. You can do this either of two ways:
• Reconnect the battery, then lower the scrub deck in the service test mode. (Refer to the Control
System/Service Test Mode section.)
• Connect the actuator power cord adapter to the deck actuator motor and run (lower) the deck housing.
(Refer to the Drive Nut Adjustment section for details.)
10. Pull and push the Scrub Motor back toward the rear of the machine to clear the chassis supports and
remove it at the Hopper.

11. To install a Scrub Brush Motor:
a. Follow the above steps in reverse order with the exception that the drive belt tension must be
reduced to allow the installation of the four motor mount Screws.
b. Refer to the Scrub Brush Belt Replacement section and follow the instructions on how to replace or
The Condor EcoFlex™ disc models use rotary brushes powered by permanent-magnet motors and gearbox
assemblies. The 40” decks have two scrub brushes that are both powered by one 3 HP motor/gearbox
assembly. The 45” and 48” decks have three brushes, each powered by a separate 1-1/2 HP motor/gearbox
assembly.
The scrub deck lift actuator raises and lowers the scrub deck, and automatically adjusts the deck height
while scrubbing to maintain the desired scrub pressure.
The coil sides of contactors K2, K3 and K4 get positive voltage from the Battery when the load side of contactor
K5 is closed. Contactor K5 closes when the A2 Control Board Assembly connects the K5 coil to battery ground.
Contactors K2, K3and K4 are connected to battery ground through the A2 Control Board Assembly.
The Right Brush Motor M9, Center Brush Motor M10 and Left Brush Motor M11 get positive voltage from the
Battery when the load sides of contactors K2, K3 and K4 are closed respectively. Contactors K2, K3 and K4 close
when the A2 Control Board Assembly connects the K2, K3and K4 coils to battery ground. The Right Brush Motor
M9
, Center Brush Motor M10 and Left Brush Motor M11 are connected directly to battery ground.
The Brush Actuator M2 gets voltage from the A2 Control Board Assembly which switches the polarity to move the scrub deck up or down. When the A2 Control Board Assembly receives a signal from the A3 Switch/Display

position.
The Scrub Deck Sensing Resistor R2 senses the deck size so the operator does not need to program the deck
size into the hidden menu.
As the brush motor current passes through the BRN current sense wire, which is in effect a low-value
resistor, a small voltage drop is developed across it which is proportional to the motor current. This voltage
change is inputted to pin J2-2 on the A2 Control Board Assembly. Any surrounding temperature change in
the BRN current sense wire affects its resistance, so the temperature is sensed by a thermistor built into
the A2 Control Board Assembly. This allows error correction for the temperature resistance changes in the
BRN current sense wire. When A2 Control Board Assembly senses a current draw out of the desired range it
automatically turns on the M2 actuator motor to raise or lower the scrub deck. This process is ongoing in
maintaining the operator’s selected scrub motor current load setting to sustain the desired brush working
pressure.
via the CAN BUS that the operator has pressed the scrub on switch, the A2 Control Board
sends the appropriate voltage to the Brush Actuator M2 to lower the scrub deck to the operating
Component Locations
On the 45” and 48” decks, three 1-1/2 HP
Gearmotors drive the scrub brushes directly. The
40” decks have a single 3 HP Gearmotor with two
gearboxes (one on either end) that power the two
scrub brushes.
Retracted dimension reference point is the edge of the gearbox case to the center pin weldment of the
assembled Nut Retainer. The Extended dimension reference point is the edge of the gearbox to the edge of
the plastic Spring Housing Assembly as shown in the above drawing.
Note: All adjustment settings are measured out of the machine (not attached).
7. After making the initial adjustment hold the Spring Housing Assembly and run it out enough so that the
Nut Retainer can be turned in to make up difference from the dimension targeted. For example: the rst
Retracted dimension measures 4-1/2” minus the 4-1/8 target dimension the difference is 3/8”. Turn the
Spring Housing Assembly manually 3/8”, then run the Spring Housing Assembly in under power until the
inner limit stops the motor. Readjust until the Retracted Position is as shown in the above table.
8. Hold the Spring Housing Assembly, then press the rocker switch on the actuator power cord adapter to
run the drive motor to the Extended position (wait until the motor stops).
9. Measure the position of the Spring Housing Assembly on the shaft and compare the measurement with
the Extended position shown in the above table.
10. If the measurement doesn’t match the dimension shown in the table, remove the Cam Adjuster Cover and
adjust the Extended position as follows:
• To increase the travel of the spring housing assembly, turn the adjuster clockwise.
• To decrease the travel of the assembly, turn the adjuster counterclockwise.
Note: Use a 1/2” (13mm) socket to turn the adjuster. Each click of the adjuster will change the
spring housing assembly travel 1/16 inch (1.6mm).
11. After each adjustment, hold the Spring Housing Assembly, run the actuator in and out and check both
dimensions.
12. After checking that the Spring Housing Assembly limits are set correctly, replace the Cam Adjuster Cover.
13. After adjusting the actuator

dimensions, refer to the Removal
and Installation/Scrub Brush Lift
Actuator section to reassemble
it in the machine. Refer to the
adjacent drawing to correctly
mount the top of lift motor to the
chassis by model size.
Service Note: Note the correct orientation of the Spring Housing Assembly when installing the
complete motor assembly and also run the Spring Housing Assembly to the Retracted
(in) position before you install it in the machine.
Side Skirt Replacement and Adjustment
During normal use the side skirt blades will wear in time. The operator will notice a small amount of water
leaking out underneath the side skirts. You can easily adjust the side skirt height to lower the blades to
allow the squeegee to pick up the water more effectively.
