LOWER CONTROL CONSOLE
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 handle, 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

10
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 lever, 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. 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
This control will adjust the amount of solution that is being dispersed to the floor while in one
of the scrub mode. Adjust control clockwise to increase the amount of solution being
dispersed. The solution distribution range is from zero (0) to a maximum of ¾ GPM.

11
UPPER CONTROL CONSOLE
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 driver that
the solution tank needs to be filled.
LOW BATTERY INDICATOR
The battery gauge bar icon will be flashing
to signal the operator that the machine is
almost out of power. Once this signal is displayed to the operator, all functions will shut off
including the transport mode. The operator has to turn the key switch OFF and then, ON to reset
the machine. The machine then will only have a few minutes left of reserve power for a short
Vacuum only mode to pick up remaining solution on the floor and Transport power.
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). By pulling
on the tilt-steering lever and
positioning the steering column in an
upright fashion, enables the operator
more room when climbing up and
down the machine.

12
OPERATION OF CONTROLS
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.
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 your foot pushed on the pedal
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.
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 right side of the upper control console, this switch controls the direction in which
the SCV will move when the accelerator pedal is activated. There are two arrow located on the
upper control console with LEDs in the center to indicate which mode the SCV is in. The arrow
pointing forward with the amber LED indicates the SCV is in forward mode. The arrow pointing
backward with the red LED indicates the SCV is in reverse mode.

13
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.
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 white
arrow). protects all auxiliary circuits on the machine
(headlights, horn, and back-up alarm). The 100-amp breaker
(indicated by black arrow) protects the main system circuit
(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 three 12-volt batteries
connected in series. Connect the batteries according
to the battery connection diagram (see diagram). The
recommended batteries are 210Ah (Minuteman P/N
956210).
SCRUB DECK
Minuteman offers two deck types (Cylindrical and
Disc) to fit your specific needs. The SCV design is

14
very dynamic wherein the decks are interchangeable in a matter of minutes whenever necessary
(removal of four bolts, and two quick-connects). The cylindrical brush deck has four 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
center hub and 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 with the quick release clamp by using any of the three access doors. 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.

15
SCRUB DECK SHIFT
The SCV 2426 now incorporates the new side shift feature, which allows the scrub deck to
move two inches to the right to allow users to get into tighter quarters such as under shelving
or cleaning close to walls.
The side shift is activated by a lighted three-position rocker switch located directly in front of
the drivers seat, just below the steering wheel (See figure below). The 3 position switch has 3
main functions, return (1), stop (2) and right offset (3). In order to move the deck right, ‘click’
the switch from the stop position to the right offset position, you may choose to ‘click’ stop at
any time for an arbitrary side shift, otherwise the deck will achieve it’s full two inch side shift.
In order to return the deck to its original position ‘click’ the switch to the return position.

When installing a cylindrical deck to a machine:
1. Install brushes after the deck has been mounted to avoid flat spots on the brushes.
2. Use a piece of cardboard underneath the deck to prevent scratches to the painted surface
when sliding the deck under the machine.
3. Make sure the scrub deck is oriented correctly with the spray jets towards the front of the
machine.
When installing a disc scrub deck to a machine:
1. Install brushes on the scrub deck; this aids the installer in sliding the deck assembly into
position.
2. Make sure the scrub deck is oriented correctly with the solution hose tee fitting towards
the front of the machine.
INSTALLATION INSTRUCTIONS
1. Park the machine on a flat or level surface.
2. Turn the key switch to the ON position and select
the transport mode on keyboard.

IMPORTANT NOTE WHEN INTERCHANGING SCRUB DECKS
As previously mentioned, the scrub deck brush pressure is computer controlled. However,
when interchanging the two types of decks, an additional step must be taken to ensure that the
controller correctly compensates the pressure for the type of deck that is currently installed.
Inside the main electrical box, beneath the seat there is an Orange/Violet jumper wire (shown
disconnected in Figure 1) that may or may not be connected to the terminal block, depending
on the type of scrub deck that was originally ordered with the machine. When using the Disk
Scrub Deck, the wire is disconnected. When using the Cylindrical Scrub Deck, the wire is
connected to the terminal block located in the electrical box, beneath the TRIO Controller. This
terminal block is divided into three sections, each separated by a divider. The two leftmost
sections contain one column each of spade terminals. The section on the right contains three
columns of spade terminals (this section also contains four Red/Black wires, not shown in
Figure 2 for clarity). The Orange/Violet wire must be connected to a spade terminal in the
section with three columns when using the Cylindrical Scrub Deck ONLY!
When switching from the Cylindrical Scrub Deck to the Disk Scrub Deck, be sure to
disconnect the Orange/Violet wire. When switching from the Disk Scrub Deck to the
Cylindrical Scrub Deck, connect the Orange/Violet wire to any available spade terminal in the
section that contains three columns (shown in Figure 2) and the Red/Black wires.
