IMPORTANT SAFETY INSTRUCTIONS 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. The following information below may cause a potential hazard to the operator and equipment. Read this manual carefully and be aware when these conditions can exist.
Avoid contact with battery acid. Battery acid can cause burns. When working on or around batteries, wear protective clothing and safety glasses. Remove metal jewelry. Do not lay tools or metal objects on top of batteries. Charging batteries generates 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 machine.
INSPECTION Carefully unpack and inspect your SCV Rider Scrubber for shipping damage. Follow unpacking instructions on shipping pallet. Each unit has been tested and thoroughly inspected before shipment. Any damage is the responsibility of the delivery carrier who should be notified immediately. ELECTRICAL This machine is battery operated and designed to operate on 36 volts DC (3) 12-volt batteries. BATTERIES The recommended batteries are rated 210Ah (Minuteman P/N 956210).

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.
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.
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.
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.
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 Emag 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.
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.
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).
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.
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.
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.
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.
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. Each blade configuration has two usable edges. The rear blade however has four usable edges.
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.
OFF-AISLE WAND (Optional) 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.
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.
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.
sure to tightly secure the Stopper plug and cleanout cap before continuing to operate the scrubber. 17. Refill the solution tank and continue scrubbing until the job is done or when the machine runs out of power. 18. The battery gauge bar icon will flash to signal the operator that the machine is almost out of power.
