CONTROL CONSOLE
For operator ergonomics, the control console houses all the primary function controls in a
central area. The key switch and optional headlight and off-aisle wand switches are clustered in
the back portion of the console. The directional switch (forward/reverse) is located at the front of
the console for easy fingertip operation. The horn button, function selectors, and battery gauge
are located in the central part of the console.
KEY SWITCH (A) – Controls the machine’s power (ON/OFF) with a key for safety. All
operational settings are retained even when the power is turned off and on. This also serves as
a reset switch when errors or faults occur.
OFF AISLE WAND SWITCH (OPTIONAL) (B) – ON/OFF control for the water supply to the
wand and vacuum motor for the optional Off-Aisle Wand.
HEADLIGHT SWITCH (OPTIONAL) (C) – ON/OFF control for the optional headlights.
BATTERY GAUGE (D) - Displays the level of charge remaining in the machine’s batteries. The
gauge consists of 10 LEDs. (3 Green, 4 Amber, 3 Red) If the battery life is low, the battery
gauge bar icon will be flashing to inform the operator that the machine is almost out of power.
Once this signal is displayed, all functions will shut off, including transport mode. The operator
must then turn the key switch OFF and then ON to reset the machine. The machine will then
have only a few minutes left of reserve power to briefly use Vacuum Only mode to pick up any
remaining solution on the floor and Transport mode to return to the charging station. This gauge
will also display a fault code if the system has an error. This code is represented by a specific
number of flashing LEDs. See Fault/Diagnostic Codes for specific code information.
SOLUTION CONTROL KNOB (E) – Adjusts the amount of solution being dispensed to the
floor while in one of the scrub modes. Turn the knob clockwise to increase the amount of
solution being dispensed. The amount of solution applied is variable to a maximum of 1 GPM.
MODE SELECTOR KNOB (F) – This knob is used to select the desired operation mode of
the machine. See Operation Modes for information about each mode.
HORN BUTTON (G) – Depressing this button will activate the machine’s horn.
DIRECTIONAL SWITCH (H) – Flipping this switch to the down position will set the machine
to move forward. Flipping it to the up position sets the machine to move in reverse.

13
OPERATION MODES
1. REGULAR SCRUB MODE
When the machine is running in this
mode, the machine will perform all
operations. This mode can be used for
day-to-day tasks under normal
conditions. When the operator sets the
directional switch to forward and
activates the accelerator pedal, the
solution pump will turn on, the brushes
will turn on and be lowered to the floor,
as well as the rear squeegee. While
operating in this mode, the solution will
be dispersed into the brushes, which will
scrub the floor allowing the chemical in
the solution to break down the dirt on
the floor. As the machine continues to
move forward, the rear squeegee and
vacuum system will recover the dirt and
dispensed solution. If the operator stops
moving, the machine will automatically
raise the scrub deck and turn off the
brushes. If the directional switch is
changed to reverse the machine will
continue to operate normally, only the
rear squeegee will raise up.
2. HEAVY SCRUB MODE
This mode is similar to Regular Scrub. The machine will continue to operate the same
was as if it was in Regular Scrub Mode, only this mode applies more solution and brush
pressure is increased. This mode is used for high traffic areas and areas that have
been heavily soiled, but do not require time for the solution to soak.
3. DOUBLE SCRUB MODE
When the machine is running in this mode, the machine will perform all operations
except dirty solution recovery. This mode can be used if the floor is heavily soiled and
the chemical will need additional time to emulsify grease and oils that are on the floor.
When the operator sets the directional switch to either the forward or reverse position
and activates the accelerator pedal, the solution pump will turn on, the brushes will turn
on and be lowered to the floor. While operating in this mode, the solution will be
dispersed into the brushes, which will scrub the floor allowing the chemical in the
solution to break down the dirt on the floor. As the machine continues to move forward
or back, the rear squeegee and vacuum system are not on, which allows the solution to
stay on the floor emulsifying the grease and oil. If the operator stops moving in either
direction, the machine will automatically raise the scrub deck and turn off the brushes.

14
After double scrubbing, the operator should use the vacuum only mode to recover the
dirty solution water from the floor.
4. VACUUM ONLY MODE
When the machine is running in this mode, the machine will only lower the rear
squeegee and turn on the vacuum system to recover the dirty solution from the floor.
This mode is usually chosen after double scrubbing to recover the dirty solution but it
can also be used to pick up spills. When the operator sets the directional switch to
forward, the rear squeegee will be lowered to the floor as the vacuum turns on, pulling
the dirty solution water from the rear squeegee into the recovery tank. If the operator
stops moving forward and sets the directional switch to reverse, the rear squeegee will
retract (protecting it from damage) and the vacuum motor will turn off after a few
seconds. If the operator quits moving in either direction, the machine will automatically
raise the squeegee and turn off the vacuum motor after a few seconds.
5. TRANSPORT MODE
When the machine is set in this mode, none of the cleaning functions of the machine will
operate. This mode is only used to transport the machine from one location to another
at a faster rate of speed.
6. SOLUTION CONTROL KNOB
This control will adjust the amount of solution that is being dispersed to the floor while in
one of the scrub modes. Adjust the control clockwise to increase the amount of solution
being dispersed. The amount of solution applied is variable to a maximum of 1 GPM.
7. BATTERY GAUGE
This gauge displays the level of charge remaining in the machine’s batteries. The gauge
consists of 10 LEDs. (3 Green, 4 Amber, 3 Red) If the battery life is low, the battery
gauge bar icon will be flashing to inform the operator that the machine is almost out of
power. Once this signal is displayed, all functions will shut off, including transport mode.
The operator must then turn the key switch OFF and then ON to reset the machine. The
machine will then have only a few minutes left of reserve power to briefly use Vacuum
Only mode to pick up any remaining solution on the floor and Transport mode to return
to the charging station. This gauge will also display a fault code if the system has an
error. This code is represented by a specific number of flashing LEDs. See
Fault/Diagnostic Codes for specific code information.

15
FAULT / DIAGNOSTIC CODES
When an error or fault occurs within the machine, a fault code will appear on the battery
gauge represented by a specific number of flashing LEDs. The figure below shows a
listing of the different codes.
FAULT / DIAGNOSTIC CODES DECAL

16
EMPTY SOLUTION TANK INDICATOR
Once the solution tank has become
empty, the battery gauge will blink a
solid 9 LEDs at a constant interval to
alert the operator that the solution tank
needs to be filled.
LOW BATTERY INDICATOR
If the battery life is low, the battery gauge bar icon will be flashing to inform the operator
that the machine is almost out of power. Once this signal is displayed, all functions will
shut off, including transport mode. The operator must then turn the key switch OFF and
then ON to reset the machine. The machine will then have only a few minutes left of
reserve power to briefly use Vacuum Only mode to pick up any remaining solution on
the floor and Transport mode to return to the charging station.
POWER SAVE MODE
The SCV is equipped with a power save feature to conserve battery power. If the key
switch power is left ON and none of the controls are activated for a period of fifteen
minutes, the SCV automatically goes into “power down mode” and turns OFF the power
to conserve your batteries in case the operator forgets to turn the key switch off or
leaves the machine unattended.

17
OPERATION OF CONTROLS
STEERING WHEEL
The steering wheel is adjustable for
operator comfort by pulling the tilt-
steering lever up and positioning the
steering wheel up or down (there are
three possible positions). Pulling on the
tilt-steering lever and positioning the
steering column in an upright position
provides the operator with more room
when climbing up and down the
machine.
ACCELERATOR PEDAL
Located on the right side of the operator compartment on the floor is the accelerator
pedal. This pedal controls the propelling speed of the machine. The farther the pedal is
pushed down the faster the machine will travel. As discussed earlier, the directional
switch governs the direction of travel the machine will take. Switching the directional
switch with the pedal depressed will make your machine change directions (a very slight
delay may occur before the direction of travel changes when switching directions on the
fly). The accelerator pedal is interlocked with the seat switch, making machine
propulsion not possible without the operator sitting on the seat. The accelerator pedal is
also linked to the machine’s dynamic braking system. During operation, when the
accelerator pedal is released, the dynamic braking system will automatically halt the
movement of the machine without need for an additional brake pedal.
SEAT
The ergonomically designed seat is located on top of the solution tank. There is a lever
under the seat that allows the operator to adjust the seat forward or backward for
operator comfort. There is an interlock switch located inside the seat. This makes it
impossible to engage the traction drive circuitry without the operator on the seat. If the
operator were to fall off the machine, the traction drive circuitry would turn off.
DIRECTIONAL SWITCH
Located on the lower front of the control console, this switch controls the direction in
which the SCV will move when the accelerator pedal is activated. Flipping this switch to
the down position will set the machine to move forward. Flipping it to the up position
sets the machine to move in reverse.
PARKING BRAKE
This machine is equipped with an Electro-magnetic brake built-in on the traction drive
motor. When the machine’s power is turned off (using either the key or the emergency
button), the E-mag brake is activated and the traction motor is prevented from moving.

18
EMERGENCY DISCONNECT BUTTON
This button is located in the middle of
the electrical panel that is directly
underneath the operator’s seat. When
the red emergency button is pressed,
power will be turned off. Use this button
in case of a machine emergency. The
red knob needs to be raised in order to
run the machine. To reactivate, turn the
knob as shown by the arrows on the
switch and the button will pop up. All
operational settings are retained even
when the power is turned off and on.
CIRCUIT BREAKERS
The circuit breakers are located next to
the emergency disconnect button. The
6-amp breaker (indicated by black
arrow) protects all auxiliary circuits on
the machine. The 100-amp breaker
(indicated by white arrow) protects the
main system circuit (TRIO controller).
Each main component is individually
protected with an internal breaker built-
in the controller. (See fault code table)
and can be reset by turning the key
switch off a few seconds and then on
again. The 100 amp circuit breaker can
also be used as a main power
disconnect, this should be used only in
case of emergency. When tripped the
breaker removes power from the main
controller and all auxiliary power circuits.
BATTERY COMPARTMENT
The battery compartment is located on the rear of the machine under the recovery tank.
Unlatching the two safety latches on the side of the machine enables the operator to tilt
the recovery tank and access the batteries for servicing and maintenance (make sure
recovery tank has been drained before tilting). The battery compartment contains six, 6-
volt batteries connected in series. Connect the batteries according to the battery
connection diagram (see diagram). The recommended batteries are 275Ah (Minuteman
P.N. 956740). The two batteries positioned in the center are offset and held in position
by two steel spacers. These spacers keep the batteries from sliding inside the battery
compartment during machine use and prevent undesired stresses in the battery cables.
Be sure to replace these spacers whenever reinstalling batteries.

SCRUB DECKS
Minuteman offers two deck types (Cylindrical and Disc) to fit your specific needs. The
SCV design is very dynamic wherein the decks are interchangeable in a matter of
minutes whenever necessary (removal of four bolts, one hose, and one electrical
connection). The cylindrical brush deck has five built-in spray jets to uniformly dispense
cleaning solution on the floor and a wet sweeping debris tray to collect loose objects on
the floor. The disc brush deck dispenses cleaning solution through the two center hubs
and the solution is contained within the bristle area for efficient agitation of cleaning
solution to the floor and channeled to the rear of the machine. The disc brushes are also
easily removed and installed by easily removing the side deck covers and releasing the
quick release clamp. Another nice feature that these scrub decks have is the ability to
have uniform brush pressure applied to the floor at all times. Since the scrub deck brush
pressure is computer controlled, it will automatically adjust and compensate to uneven
contours on the floor while maintaining brush pressure.
