Operators must read and understand this manual before operating or maintaining this machine. Do not operate this machine in flammable or explosive areas. This machine is designed solely for scrubbing dirt and dust in an indoor environment. Minuteman does not recommend using this machine in any other capacity.
This machine is battery operated and designed to operate on 36 Volts DC (6) 6-volt batteries. BATTERIES The recommended batteries are rated 275Ah (Minuteman P.N. 956740). We do not recommend mixing Amp Hour capacities. Any alternate battery sets can be used if they are of equal physical size and capacity. See “Battery Compartment” for service and installation.

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.
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,...
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.
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...
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.
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...
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.
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).
SCRUB DECK INSTALLATION 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.
d. Align the notches on the brush with the drive pins on the hub. e. Push the brush all the way in until it bottoms out. f. Insert the access door hub into the other end of the brush. g. Reinstall the wing nuts and yellow 3 sided knobs and tighten. IMPORTANT NOTE WHEN INTERCHANGING SCRUB DECKS As previously mentioned, the scrub deck brush pressure is computer controlled.
SIDE SQUEEGEES 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.
CYLINDRICAL DECK SIDE SQUEEGEE COMPONENTS Side Squeegee Blade Black Squeegee Adjustment Knob (2) Yellow Brush Access Knob Side Squeegee Hinge 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.
REAR SQUEEGEE 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.
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 A) for uniform deflection to the floor.
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.
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.
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.
Foam Filter Clean Hopper on Cylindrical System • Have Minuteman check the vacuum motor carbon motor brushes once a year or after 300 operating hours. The brush motor carbon brushes should be checked every 500 hours or once a year.
