FUNCTIONAL DESCRIPTION OF CONTROL BUTTONS:

The controls were designed with one touch operation in mind. For single pass scrubbing the user can simply depress one button 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 fi rst three buttons on the control panel. These are the Scrub Off (25),
Normal Scrub (26), and Heavy Scrub (27) buttons. For this reason these buttons are outlined in bright white on the control panel while the other buttons are
outlined in a darker color.

Horn Button (22) - Pressing this button will activate the horn.
Scrub Off Button (25) - Pressing this button when the unit is in a scrub mode will cause the following to occur:

• The scrub brushes will turn off

• The scrub deck will raise to the UP position

• The solution fl ow will be stopped

• The fi rst time that this button is pressed, the vacuum/squeegee 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 button is pressed a second time (pressed after the scrub mode has been turned off) the squeegee will
raise and the vacuum will shut off after a 6 second delay.

Normal Scrub Button (26) - Pressing the normal scrub button will enable the scrub system and set the scrub pressure to the last selected value for the nor­mal scrub mode. The status display will momentarily display the scrub pressure setting. This is indicated by “PA” followed by a number. Subsequent presses
of the normal scrub button will step the pad pressure setting through the allowable range up to the maximum value programmed for the normal scrub mode.
Once the maximum value is reached the pressure setting will step back to 1. The factory default maximum for the normal scrub mode is 4. The following will
occur when this button is pressed:

• The scrub deck will be lowered

• The vacuum and solution systems will be enabled (vacuum and solution modes = AUTO)

• As soon as a direction is commanded by the throttle (forward or reverse) the brushes will start turning and the vacuum will turn on. If the direction is
forward, the squeegee will lower and the solution fl ow will start. If the direction is reverse, the squeegee will go to the up position and the solution fl ow will
be stopped.

Heavy Scrub Button (27) - Pressing the heavy scrub button will enable the scrub system and set the scrub pressure to the last selected value for the heavy
scrub mode. The status display will momentarily display the scrub pressure setting. This is indicated by “PA” followed by a number. Subsequent presses
of the heavy scrub button will step the pad pressure setting through the allowable range up to the maximum value programmed for the heavy scrub mode.
Once the maximum value is reached the pressure setting will step back to (normal scrub limit + 1). The factory default maximum for the heavy scrub mode is
7 (cylindrical) or 9 (disc). The following will occur when this button is pressed:

• The scrub deck will be lowered

• The vacuum and solution systems will be enabled (vacuum and solution modes = AUTO)

• As soon as a direction is commanded by the throttle (forward or reverse) the brushes will start turning and the vacuum will turn on. If the direction is
forward, the squeegee will lower and the solution fl ow will start. If the direction is reverse, the squeegee will go to the up position and the solution fl ow will
be stopped.

Vacuum Button (29) - This button is used to select the mode of operation for the vacuum/squeegee system. There are 3 modes of operation for this system.
These modes are OFF, AUTO, ON. Following is a description of each mode and how they are selected.

OFF MODE: In this mode the vacuum is off and the squeegee is in the up position. As mentioned above, when a scrub mode is selected, the vacuum
system will be placed in the AUTO mode. If it is desired to double-scrub (scrub without recovering the solution) the vacuum system can be turned off by
pressing this button.

AUTO MODE: This mode is automatically selected when a scrub mode is selected. In this mode the squeegee will be in the down position unless the re­verse direction is selected via the throttle. The vacuum will turn on if either direction is selected. While in this mode the vacuum will remain on for 10 seconds
after the throttle returns to the neutral position. This is so that the solution in the squeegee and hose can be drawn into the tank. This mode can be selected
independently of the scrub mode by pressing and releasing the vacuum button.

ON MODE: In this mode the squeegee will remain in the UP position and the vacuum will be on regardless of the throttle position. This mode is selected
by pressing and holding the vacuum button for approximately 1.5 seconds. The vacuum mode must fi rst be OFF before entering this mode. This mode is
included in the event an external wand is to be used with this machine or if the operator wants to clean the squeegee using the vacuum hose.

Solution Button (30)

- This button is used to select the mode of operation for the solution system. There are 3 modes of operation for this system. The

modes are OFF, AUTO, MOMENTARY ON. Following is a description of each mode and how they are selected.
OFF MODE: In this mode the solution fl ow is turned off. As mentioned above, when a scrub mode is selected, the solution system will be placed in the

AUTO mode. If it is desired to scrub without dispensing solution, the solution can be turned off by pressing this button.
AUTO MODE: This mode is automatically selected when a scrub mode is selected. In this mode the solution fl ow will be turned on whenever the forward

direction is selected via the throttle. The solution fl ow will be turned off otherwise.
MOMENTARY ON MODE: This mode can only be selected when the scrub mode is OFF. Solution can be dispensed by pressing and holding the solution

button. Solution will be dispensed for as long as the button is held. This is for pre-wetting the fl oor prior to scrubbing.
Presweep Dust Control Button (opt / 39) - Use this button in conjunction with the optional presweep kit. The dust control feature will only work when the

brooms are running on the presweep unit.
Sweep System Control Button (2042 / BR 1100C-XL only) (43) - Use this button to turn the sweep system ON or OFF. The side brooms will only run when

the scrub system is ON and the machine is in motion (not in neutral). If the scrub system is turned OFF while the sweep system is still ON, the side brooms
will automatically lower and run the next time the scrub system is turned ON.

Side Broom Wear Adjustment Lever (2042 / BR 1100C-XL only) (44) - Use this adjustment lever to periodically re-adjust the down limit of the side brooms
as they wear. Loosening the lever, sliding it to the left and re-tightening it will cause the side brooms to drop closer to the fl oor.

Operator Seat Adjustment Lever (45) – Use this lever to slide the operator’s seat forward or backward.

DESCRIPTION OF INDICATORS ON THE CONTROL PANEL:

In general, the following guidelines apply to the control panel indicators:
A steady red indicator means that the function is inhibited for some reason. For example, if the scrub system is off and the operator is not on the seat, the
scrub system indicator will be red indicating that the system cannot be turned on until the operator is on the seat.

A fl ashing red indicator means that a fault has occurred in the particular system. An example of this would be an over-current fault.
A yellow indicator means that the particular function has been enabled 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 or reverse.

A green indicator means that the particular system is on.
A fl 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 fl ash green indicating that the vacuum is still on but that it will be turn-
ing off after the delay period.

Scrub Mode Off Indicator (34):

• This indicator will be RED if the scrub system is inhibited for any reason. Possible reasons are:

• Seat switch is open

• The scrub deck has not returned to the UP position.

• A system fault

• Low voltage condition

• This indicator will be GREEN if the system is ready to be placed in either the normal or heavy scrub modes.

• This indicator will be OFF if either the normal or heavy scrub modes have been selected.

• This indicator will fl ash RED if there is a fault in one of the scrub system components. This will be accompanied by an error indication on the Hour Meter / Status Display

(32).

Normal Scrub Mode Indicator (35):

• This indicator will be YELLOW if the normal scrub mode has been selected but the scrub motor is off. This will be the case if the throttle is in the neutral position. The scrub
motor will stay on for approximately 3 seconds after the throttle returns to the neutral position.

• This indicator will be GREEN if the normal scrub mode has been selected and the scrub motor is on.

• This indicator will be OFF if the scrub mode is off or if the heavy scrub mode has been selected.

Heavy Scrub Mode Indicator (36):

• This indicator will be YELLOW if the heavy scrub mode has been selected but the scrub motor is off. This will be the case if the throttle is in the neutral position. The scrub
motor will stay on for approximately 3 seconds after the throttle returns to the neutral position.

• This indicator will be GREEN if the heavy scrub mode has been selected and the scrub motor is on.

• This indicator will be OFF if the scrub mode is off or if the normal scrub mode has been selected.

Vacuum System Indicator (37):

• This indicator will be YELLOW if the vacuum/squeegee system is in the AUTO mode and the throttle is in the neutral position. This indicates that the vacuum system is
enabled but the vacuum is currently off.

• This indicator will be GREEN if the vacuum is currently on. This indicates that the system is in the AUTO mode and the throttle is not in neutral or that the vacuum system is
in the ON mode.

• This indicator will FLASH GREEN if the shutoff delay is keeping the vacuum on. This occurs if the vacuum system is in the AUTO mode and the throttle goes to the neutral
position. This will also occur if the vacuum system is turned off while it was in either the AUTO or ON modes. The shutoff delay will turn the vacuum off after the delay
period.

• This indicator will be OFF if the vacuum/squeegee system if in the OFF mode.

Vacuum System Fault Indicator (38):

• This indicator will fl ash red if there is a fault in the vacuum or squeegee systems. This will be accompanied by an error indication on the Hour Meter / Status Display (32).

• This indicator will be RED and the Hour Meter / Status Display (32) will show “FULL” if the recovery tank fl oat valve has closed. If this indication occurs and the tank is not
full, see the Troubleshooting section.

Solution System Indicator (28):

• This indicator will be YELLOW if the solution system is in the AUTO mode and the throttle is in the neutral or reverse positions. This indicates that the solution system is
enabled but the solution fl ow is currently off.

• This indicator will be GREEN if the solution system is in the AUTO mode and the throttle is in the forward position. It will also be GREEN if the solution system is in the
MOMENTARY ON mode. This indicates that the solution fl ow is currently on.

• This indicator will be OFF if the solution system is in the OFF mode.

Solution System Fault Indicator (24):

• This indicator will fl ash red if there is a fault in the solution system. This will be accompanied by an error indication on the Hour Meter / Status Display (32).

Main Power Indicator (23):

• This indicator will be GREEN when the key switch is ON.

• This indicator will fl ash RED if there is a system fault that requires turning the Master ON/OFF Key Switch (33) off to reset.

• This indicator will fl ash fault codes from the Curtis Speed Control if a fault exists. This will be accompanied by an “Err03” indication on the Hourmeter/Status Display (32).

Presweep Dust Control Indicator (40):

• This indicator will be GREEN when the dust control feature is ON.

• This indicator will be YELLOW when the dust control feature is enabled but not ON.

• This indicator will be OFF if the dust control feature is not enabled or unit has the optional side broom kit installed.

Presweep Power Indicator (41):

• This indicator will be GREEN when either the optional presweep or side broom kits are installed and turned ON.

• This indicator will be YELLOW when either the optional presweep or side broom kits are installed and enabled, but not ON (machine in neutral).

• This indicator will be fl ashing YELLOW when the optional side broom kit is installed, selected and turned ON, but the scrub system is OFF.

• This indicator will be OFF if the foot pedal on the optional presweep or side broom kits is UP.

Sweep System Power Indicator (2042 / BR 1100C-XL only) (42):

• This indicator will be GREEN when the sweep system is turned ON.

• This indicator will be YELLOW when the sweep system is enabled, but not ON (machine in neutral).

• This indicator will be OFF if the sweep system is turned OFF.

DESCRIPTION OF THE BATTERY CONDITION INDICATORS

The battery condition indicators will give an indication of the state of charge of the batteries. The battery condition monitor will retain the state-of-charge even
if the key has been turned off. The state-of-charge indication 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 batteries are being used (have qualifi ed service engineer
perform this selection). NOTE: The following percentages are based on useable 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.

Green Indicator = full charge down to 50% discharge
Green & Yellow Indicator = 50% discharge down to 75% discharge
Yellow Indicator = 75% discharge down to 90% discharge
Yellow & Red Indicator = 90% discharge down to 95% discharge
Red Indicator = 95% discharge down to 99% discharge
Flashing Red Indicator = 100% discharge - scrub system will automatically shut down

DESCRIPTION OF HOURMETER / STATUS DISPLAY

The 5 character display in the middle of the bottom row of the control panel is primarily used as a display for the hourmeter function. This display is also
used to display the following information depending upon which mode the control is in:

• Error codes*

• Brush pressure adjustment settings for normal and heavy scrub mode (fi xed and adjustable)*

• Display of control system default parameters*

• Recovery tank FULL indicator*
* NOTE: Have a qualifi ed service engineer reference the Service Manual for explanations about the error code descriptions and scrub system control default
parameter changes. A brief description of error codes can be found at the back of this manual.

Emergency Stop Switch / Battery Disconnect (12): This will remove all power from the machine.
