(make sure recovery tank has been drained before tilting). 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 370Ah (Minuteman P/N 956715). -
Page 17: Scrub Deck
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 five 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. -
Page 18: Scrub Deck Installation
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. - Page 19 SIDE SQUEEGEE The side squeegees (left and right) are attached to the machine mainframe. 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. When the scrub deck is deployed, the side squeegees are also lowered.

Page 20: Rear Squeegee
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. -
Page 21: Rear Squeegee Adjustment
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. -
Page 22: Off-Aisle Wand Tool
OFF-AISLE WAND TOOL 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. -

LCD panel) using the tilt wheel lever. 2. Turn the Key switch ON (I). The LCD panel will light up and display the Minuteman logo for a few seconds and display the Battery Condition icon and the last functional setting when the machine was turned off. - Page 24 7. 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.

Page 25: After Use
AFTER USE: 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. -
