  • Page 19: How The Machine Works

    OPERATION HOW THE MACHINE WORKS The following machine components work together to effectively clean dirty floors: solution tank, scrub brushes, squeegee, vacuum fan, and recovery tank. Water and detergent from the solution tank flow to the floor through a solution valve. The brushes use the detergent and water solution to scrub the floor clean.
  • Page 20 OPERATION FaSTt t t t SCRUBBING SYSTEM (OPTION) Unlike conventional scrubbing, the FaSTt (Foam Scrubbing Technology) system operates by injecting the FaSTt PAK concentrate agent into the system with a small amount of water and compressed air. This mixture creates a large volume of expanded wet foam.

  • Page 21: Pre-Operation Checklist

    OPERATION PRE-OPERATION CHECKLIST Check over this list of items before operating the machine: - Check under the machine for leaks. - Check the brakes and steering for proper operation. - Check for wire, string, or twine wrapped around the scrub brushes. - Check the squeegees for wear or damage.
