    6. PRE-USE SETUP TURNING THE UNIT ON/OFF The key switch is located on the control panel. When the machine is not in use, remove the key and store it in a secure location. CIRCUIT BREAKERS The circuit breakers on the control panel protect the components from high amp-draw. In particular, the scrub head circuit will draw too many amps when overloaded by improper application setup.

  • Page 16: Driving Operation

    PAD/BRUSH ASSIST BATTERY POWER LEVEL INDICATOR Pad/brush assist models have a Power Level Indicator that uses seven LEDs to communicate the level of charge in the batteries. When the LED starts to flash, the brush motor will shut down but the vacuum will still recover water. NOTE: The Power Level Indicator will display the lowest level indicated and will not reset until a full charge has been applied.

  • Page 17: Filling The Solution Tank

    8. SOLUTION DISTRIBUTION FILLING THE SOLUTION TANK Use liquid detergent in the concentration and manner specified by the manufacturer for a 22-gallon solution tank. Excess foam will damage the vacuum motor. In addition to properly-mixed low-foam detergent, use a small amount of de-foaming liquid in the recovery tank. Never use pure acids. NOTE: The front fill port strainer blocks debris from falling into the tank.

  • Page 18: Head Lift

    INSPECTION & CLEANING NOTE: If excessive debris is present, drain and flush the solution tank. 1. Close the shutoff valve. 2. Remove the filter bowl and screen. 3. Clean and rinse any debris in the filter assembly. 9. SCRUB DECK SETUP HEAD LIFT •...

  • Page 22 SQUEEGEE USE 1. Lower: Lift the squeegee lever, shift it left, and lower. The vacuum motor will activate. 2. Raise: Lift the lever and shift it right. The vacuum motor will run for 10 seconds to prevent recovered solution from running back out of the hose. HEIGHT ADJUSTMENT If the squeegee blade height requires adjustment, turn the button screws on the squeegee frame assembly clockwise to raise and counter-clockwise to lower the wheels until proper blade deflection is achieved.
  • Page 23 CLEAN & INSPECT 1. Inspect both squeegee blades. If the blade edges are not clearly defined or are worn halfway through the thickness of the blade, flip the blades to another edge or replace as required. 2. Thoroughly clean and rinse the underside of the squeegee frame, blades and neck.
