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.

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.

Parts and Instruction Manual

Page 6

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Circuit Breakers

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).

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.

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.

Scrub Deck

Disc Scrub Deck

Cylindrical Scrub Deck

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, 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.

Scrub Deck Shift

123 Detailed View of 3-Position Switch

Location of Side Shift Switch

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.

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 five sections, each separated by a divider. The four

leftmost sections contain one column each of spade terminals. The section on the right contains two 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 two 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 two columns (shown in Figure 2) and the Red/

Black wires.

Side Squeegee

The side squeegees (left and right) are attached to the scrub decks. These items channel the dirty solution to

the rear squeegee, helping contain the water within the machine’s cleaning path. These squeegees are raised

when the scrub deck is in the raised position.

The side squeegees are pre-adjusted at the factory. Adjustments may be required when replacing worn

blades or to achieve optimum performance for different floors and conditions.

To adjust the side squeegees, simply loosen the two (front and back) wing nuts (item 1) located behind the side

squeegee blades. Lower the scrub deck by switching to a scrubbing mode and when the brushes start up, turn

off the key switch. At this point the side squeegees should be resting vertically (no deflection) on the floor.

Press down on the side squeegee bracket assembly from each end while making sure that the blade is uniformly

deflected in a 45 degree angle along its whole length. Tighten the wing nuts. Turn the steering wheel all the way

to the left or right and start pushing the machine to the side to inspect the blade deflection and wiping action.

Repeat the steps above until a satisfactory result is obtained. (See the following page for the location of the

fasteners on the cylindrical deck, marked Item 2).

Parts and Instruction Manual

Page 15

Brush Changes on the Cylindrical Deck

In order to change the brushes on the cylindrical deck the side squeegee must be moved in order to

access the brush doors. The cylindrical deck was designed so one can change the brushes without

having to realign the side squeegees. This is accomplished by removing a knurled knob (Item 1) and

swinging the squeegee along the hinge bracket located at the front of the deck, gaining access to the

brushes. Once completed inserting new brushes, replace the brush doors and swing the squeegee back

into place, tightening down the knob (Item 1).

In order to remove or adjust the alignment of the side squeegees on the cylindrical deck, remove the 3

sided knobs (Item 2) and lock washers, and follow the instructions on the previous page.

The rear squeegee is the main element that acts as the conduit that transfers the spent solution into the

recovery tank. A daily maintenance check of this component is essential to have optimum machine performance.

The rear squeegee assembly is equipped with a universal front blade that allows the operator the option to use

a slotted and a non-slotted side for specific applications. Each blade configuration has two usable edges. The

rear blade however has four usable edges.

The squeegee is pre-adjusted at the factory. Adjustments may be required to get optimum performance

for different floors and conditions.

Parts and Instruction Manual

Page 17

Rear Squeegee Adjustment

1. Ensure that the scrubber is on a relatively flat surface. Turn on the key switch and select the Vacuum only

mode. This lowers the squeegee to the floor and turns the vacuum motor on.

2. Move the scrubber one or two feet forward slowly while someone behind the machine checks the rear

squeegee blade (item 1) for uniform deflection to the floor.

3. If uneven deflection or lay is evident, minor adjustments may be necessary to avoid streaking and uneven

wear on the blade.

4. To correct this, loosen the wing jam nut (item 12) in order to adjust the caster height. If the squeegee blade is

deflecting too much, the casters (item 8) need to be lowered to control the down pressure. Lower the caster

by turning the exposed threaded stem on the caster clockwise. Make the adjustment a few turns at a time.

Repeat step 2.

5. If the blades are not deflecting enough, raise the caster by turning the stem counter-clockwise to adjust the

caster height to allow more down pressure on the squeegee. Repeat step 2.

6. Make sure there is even deflection on the entire length of the rear blade. Adjust the casters and retighten the

wing jam nuts to lock the caster setting in place.

7. Pitch adjustment is necessary if the outer ends on the squeegee blade do not contact the floor and there is too

much deflection in the middle area or if the outer ends are over deflected and there is no contact in the

middle.

8. To adjust the pitch, Repeat step 2.

9. Loosen the two wing nuts (item 5) that lock the pitch angle. Turning the knob (item 3) clockwise or counter-

clockwise controls the forward and backward pitch of the squeegee. Having the rear blades deflected uni-

formly along its entire length is the desired set-up.

10. Repeat step 2 until desired set-up is achieved.

11. In certain applications where a non-slotted front wiper blade (item 18) is needed, detach the rear squeegee

assembly by loosening the two wing bolts (item 16). Unlock the toggle clamp (item 15) on the front squee-

gee to release the front long strap (17) and slide the front short strap (item 13). Flip the blade over to the non-

slotted side. Reattach the straps and lock the clamp back in place.

12. You can also easily replace the rear blade by unlatching the latch (item 4) and removing the two rear straps

(items 1 & 5) by sliding them off the assembly. You can then flip the blade over in order to use a new edge for

Off Aisle Wand (Optional)

When the off-aisle wand switch is turned ON, the off-aisle wand switch LED will be lit as well as the battery

gauge will flash to indicate that you are in the off-aisle tool mode. This switch turns on the pump to supply

solution to the wand spray jet and the vacuum motor to recovery the dirty water. When the recovery tank is full,

the vacuum motor and the solution pump automatically shuts off.

The SCV is equipped with a ready-to-use built-in telescoping off-aisle wand system for use in hard to reach

areas. By turning the pump switch ON (located on the control console, see page 11 for illustration) the off-aisle

wand is ready to use in seconds. The wand is also equipped with the patented flip-flop tool that allows the

operator to switch from scrub brush to squeegee tool by just rotating the tool end.

OFF-AISLE WAND TOOL (Optional)

The off-aisle wand tool as described in the previous page is composed of the following items:

1. The recovery hose is connected to the end of the wand on one end and to the diverter assembly (item F)

on the other end. This hose has swivel cuffs on both ends that allow the operator a good range of motion

and the solution hose to be inside the recovery hose.

2. The trigger controls the solution flow to the spray jet. Squeezing the trigger opens an internal valve to

dispense cleaning solution.

3. The coiled solution hose acts as a conduit from the trigger to the spray jet, and allows hose to be extended

along with the wand.

4. The spray jet dispenses the cleaning solution to soak soiled areas that are not accessible to the main

scrub deck.

5. The telescoping wand allows the length to be adjusted for operator comfort and better storage when not

in use.

6. Sliding the wand extender forward (as shown above) extends the wand length during use and retracts the

wand by pulling it back for the storage position.

7. The flip-flop tool gives the operator complete flexibility when changing from the scrub brush mode to

vacuum squeegee mode by simply rotating the end.

The SCV Rider

This machine was designed with total operator comfort and ease of use in mind. All machine components have

been designed as a total system to efficiently clean dirty floors. The SCV has four available scrub head types and

sizes to fit specific applications. Please contact your Minuteman representative for specific recommendations for

the correct scrub head type, size, and brush type and chemical applications.

Before using the machine, always perform the following steps to ensure proper machine operation.

•Check under the machine for leaks.

•Check the rear and side squeegees for wear and damage.

•Check the steering for proper operation.

•Check the solution and recovery tanks.

After using the machine, always perform the following steps:

•Check the battery charge level. Charge batteries if necessary. When charging batteries, extra precaution is

required:

Battery acid can cause burns.

When working on or around batteries, always wear protective clothing and safety glasses.

Remove metal jewelry. Do not lay tools or metal objects on top of the batteries.

Charging batteries generate explosive gasses.

DO NOT CHARGE BATTERIES WHEN OPEN FLAMES OR SPARKS ARE PRESENT. DO NOT SMOKE.

Make sure the charger is turned off before disconnecting it from the batteries.

Charge the batteries in a well-ventilated area.

Fluid levels should be checked before and after charging and maintained at the proper levels. If low,

add water until the metal plates are covered.

If the machine is not used for an extended period of time, batteries should be kept fully charged with

a boost charge once a week.

•Check for wire, string, or twine wrapped around the scrub brushes.

•Check the squeegees for wear and damage.

•Check the rear squeegee suction hose and off-aisle wand hose for obstructions.

•Empty and clean the debris box (cylindrical systems only).

•Drain and clean the recovery tank.

•Check under the machine for leaks.

•Check the service records to determine maintenance requirements.

WARNING!

•Be sure you understand the machine controls and their functions.

•While on ramps or inclines, avoid sudden stops when tanks are filled.

•Avoid abrupt sharp turns. Slow down driving speed when going downhill.

•Always drive up when cleaning ramps.

Machine Operation

Follow the instructions in preparing the machine for use as described in this manual.

1. While seated on the machine, adjust the steering wheel to desired position using the tilt lever.

2. Turn the Key switch ON (I). The Battery Gauge will light up and display the Remaining Battery Life.

3. Select one of the five available Modes on the Control Console for the required task. Refer to the Main

Keyboard section of this manual for a complete description of the functions.

4. Determine the direction you need to travel by selecting forward or reverse on the Directional Switch.

Vary the pressure exerted on the accelerator pedal to propel the machine at the desired speed.

5. Stepping on the Accelerator Pedal turns on the Transport, Brushes, Water Flow, Vacuum and lowers the

Rear Squeegee accordingly to the Mode selected. If the operator steps on the accelerator pedal before, or

turns the key switch “ON” at the same time, the machine will not move as a safety precaution. Simply

remove your foot off the pedal and step on the pedal again to drive the machine. Please refer to the Main

Keyboard section of this manual for a complete description of the functions.

6. When Reverse is selected on the Directional Switch, the Back-up Alarm will be activated and the Rear

Squeegee automatically is raised when you step on the accelerator pedal. However, the Scrub brushes will

continue to rotate and solution will continue to flow.

7. Start scrubbing by driving the machine forward in a straight line at 3/4 speed and overlap each path by 2 to

3 inches. Adjust your speed; brush pressure and solution flow according to the condition of the floor.

CAUTION!

To avoid any damage to the floor, keep the machine moving when the brushes are turned on.

8. When scrubbing, check behind the machine occasionally to see that all the dirty water is being picked up. If

streaking occurs, your Recovery Tank may be full, the Squeegee hose may be clogged, or the Rear

Squeegee may require some adjustment.

9. Make the necessary adjustments on the Rear and Side Squeegees if streaking occurs both in straight

paths and in turns. Pleas refer to the Rear Squeegee and Side Squeegee section of this manual before

making any adjustments.

10. In cases where the floors are extremely soiled and dirty, the Double Scrub mode may be needed. As

described in the Main Keyboard section of this manual, this mode allows the operator to be able to scrub an

area without recovering the cleaning solution with the rear squeegee in the raised position (no vacuum) to

allow the cleaning solution a longer time to loosen dirt. A final pass on the same area is made with the mode

switched over to either Full Function or Vacuum Only mode to recover the dirty water.

11. The recovery tank has a safeguard for overflow protection to guard against water from entering the vacuum

system when the recovery tank is full. The vacuum will stay ON for 15 seconds and then shut-off automati-

cally. A ball float shut-off system has also been integrated into the Recovery Tank. When the dirty water

reaches a certain level, the ball gets suctioned into the vacuum manifold and blocks the airflow thus, pre-

venting the machine from picking up more liquid. When this happens, the operator is then required to stop

scrubbing and empty the recovery tank.

12. To stop scrubbing, select the Transport mode. This will automatically stop the Solution Flow, raise the

Scrub deck, and raise the Rear squeegee (there is a 15 second delay for the vacuum motor).

13. Drive the SCV to a designated dirty water disposal area and empty the Recovery tank. To empty, remove the

Drain hose from its storage hanger. Unscrew the plug and hold the hose end above the water level in the

tank to avoid sudden, uncontrolled flow of dirty water. With the plug completely off, carefully direct the water

flow to the desired drain. Reinsert the plug and tighten and return to its storage hanger.

14. The recovery tank should be rinsed out to remove solids in the tank. Open the Cleanout cap to remove the

Stopper plug. Tilt the recovery tank (similar to accessing the batteries) and clean the sludge that has

settled in the sump area by either back flushing or by scraping it out.

Parts and Instruction Manual

Page 21

15. Be sure to tightly secure the Stopper plug and cleanout cap before continuing to operate the scrubber.

16. Refill the solution tank and continue scrubbing until the job is done or when the machine runs out of power.

17. The battery gauge bar icon will flash 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 (brush will turn off and the scrub deck will

raise up, water flow will cease, the rear squeegee will raise up and the vacuum motor will turn 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 to drive to the battery recharging station.

1. When finished scrubbing, select the Transport mode, all functions will shut off (brush will turn off and the

scrub deck will raise up, water flow will cease, the rear squeegee will raise up and the vacuum motor will turn

off). Drive the machine to a service area for daily maintenance and review items that may need service.

2. Empty the solution tank, by directly opening the Garden hose valve underneath the machine into a drain on

the floor or use a garden hose and attach it to the fitting to remotely drain the solution tank. Rinse the tank with

clean water to prevent any build-up of dried up chemicals that could cause clogging in the plumbing.

3. Empty the recovery tank as described on line 15 and 16.

4. Remove the brushes or pad holders and rinse them in warm water and hang to dry.

5. Remove the rear squeegee, rinse with warm water and reinstall after cleaning.

6. Remove the side squeegees, rinse with warm water and remove the debris box (cylindrical system only)

and clean thoroughly. The debris box can be removed from either side of the machine by tilting the box up

and away from the housing and then pulling it out. Reinstall the debris box and side squeegees after clean-

ing.

7. Check the maintenance schedule on the next page and perform any required maintenance before storing

the machine.

8. Store the machine indoors in a clean dry place. Keep from freezing. Leave solution and recovery tank lids

open for ventilation to prevent odor build-up.

9. Turn Key switch OFF (O) and remove key.
