Minuteman SCV28, Operation Service Parts Care

MAIN KEYBOARD

FULL FUNCTION MODE 

When this mode is chosen, a green indicator light will illuminate within the full function icon. When the 
machine is running in this mode, all machine functions will be on. When the operator sets the 

directional 

switch

 to the 

forward

 position and steps the 

accelerator pedal, 

the solution pump will turn on, the brushes 

will turn on and be lowered to the floor, and the rear and side squeegees will be lowered to the floor as the 
vacuum motor turns on. 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 vacuum motor will pull the dirty solution water from the rear squeegee into 
the recovery tank. If the operator stops moving forward and switches the directional switch into reverse, 
the rear squeegee will rise up (protecting it from damage) and the vacuum motor will turn off after a few 
seconds. If the operator stops moving in either direction, the machine will automatically raise and turn off 
the brushes, shut-off the water and raise the rear and side squeegees. Some of the functions will take a 
little while longer to turn off than others.

DOUBLE SCRUB MODE 

When this mode is chosen, a green indicator light will illuminate within the double scrub icon. 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 steps 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 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.

display section in this book to see the image on the screen looks like when this button is selected.

VACUUM ONLY MODE 

When this mode is chosen, a green indicator light will illuminate within the vacuum only icon. 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.

display section in this book to see the image on the screen looks like when this button is selected.

TRANSPORT MODE 

When this mode is chosen, a green indicator light will illuminate within the transport icon. 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.

INFORMATION BUTTON 

Depressing the “

i

” button will generate specific information such as the machine hour meter, brush motor 

hours, and traction motor hours on the LCD display for a few seconds. Keeping this button depressed will 
display these items of information for an indefinite amount of time until you release the button. This button 
toggles the information on the screen being displayed from machine settings and hour meter information.
