PRE-USE SETUP
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.
TURNING THE UNIT ON/OFF
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. Solution ow, oor sur-
face, and down-pressure should be considered when operating the machine (example: high down-pressure on a
rough oor with no solution ow will overload the circuit). Repeatedly tripping the breaker will cause the need
for replacement.
BATTERY POWER LEVEL & FAULT INDICATORBATTERY POWER LEVEL & FAULT INDICATOR
When switched to the ON position, the Battery Power Level Indicator illuminates indicating
the battery charge level. A full charge is indicated when all LEDs are lit. As the power level
decreases, the LEDs go out from right to left.
When the battery charge is depleted, the last red LED will ash and the brush motor will turn o. The vacuum
and traction drive will continue to function allowing nal water recovery and transport to the charging station.
NOTE: Using AGM battery-equipped units after the last yellow LED goes out can reduce the life of the
batteries.
NOTE: After a ll charge, operate the machine for at least 30 minutes before recharging the batteries again. Do
not leave the batteries discharged overnight.

SOLUTION DISTRIBUTIONSOLUTION DISTRIBUTION
FILLING THE SOLUTION TANK
Use liquid detergent in the concentration and manner specied 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 ll port strainer blocks debris from falling into the tank. Keep the solution tank free from
debris to prevent lter clogs and reduced solution ow.
1. Add water and cleaning agent via the front or rear ll port. Water temperature should not exceed 120°F
(50°C).
2. Monitor the solution level through the sight tube and the marks on the tank at the rear of the machine.
3. To drain the tank, slide the solution sight tube o of the upper tting and lower to a drain or mop sink.

INSPECTION & CLEANING
NOTE: If excessive debris is present, drain and ush the solution
tank.
1. Close the shuto valve.
2. Remove the lter bowl and screen.
3. Clean and rinse any debris in the lter assembly.
SOLUTION FLOW: NON-CHEMICAL INJECTION MODELS
The Solution Control Knob is located on the top left corner of the control panel. The valve electrically turns on
and o with the Scrub Head. The knob controls how much solution passes through the valve when activated.
OPTIONAL CHEMICAL INJECTION MODELS
1. Place a 1-gallon chemical container in the holder in the battery compartment and remove the cap.
2. Insert the leader hose so that the end is resting on the bottom of the container and screw on the cap.
3. Match the mix ration dial on the control panel to the setting (in ounces per gallon) prescribed on the
chemical’s container.
4. Set the solution ow rate to low, medium, or high.
5. A solid green LED indicates that the system is automatically mixing the chemical while the machine
operates.
NOTE: If the detergent is not priming, temporarily select a higher setting until detergent appears on the oor.
NOTE: To purge old detergent, set the mixture dial to the highest ration and run until the leader hose line is
empty.

ORBITAL PADS & CHEMICAL-FREE FINISH REMOVAL (CFR)
NOTE: Do not lower the orbital head without a pad installed. Doing so may damage the Mighty-Lok® face.
STANDARD CLEANING OPERATIONS
1. Align the corners of the pad to the corners of the aluminum plate and press to attach.
2. Lower the scrub deck onto the pad.
3. Ensure the pad is properly aligned front-to-back and left-to-right.
CHEMICAL-FREE FINISH REMOVAL (CFR) PAD ASSEMBLY
A specialized surface preparation pad, in addition to the traditional cleaning pad, is required for chemical-free
nish removal. The traditional pad acts as a “backer pad” and compensates for variances in the oor.
1. Place the black retainer pad 2” back from the front of the red
scrub pad and the maroon CFR pad to allow water saturation.
2. Align and assemble the pads with the red pad on top and the
maroon pad on the bottom facing the oor.
3. Ensure the gap mentioned in step 1 is facing forward and refer
to steps 1-3 of “Standard Cleaning Operations” above to
install the CFR Pad Assembly.
MACHINE SETUP
1. Install the CFR Pad Assembly as described above.
2. Fill the solution tank with clean water.
3. Set the down pressure to Heavy (see “Selecting Down Pressure” above).
4. Set the solution ow to midrange. Adjust as needed for maximum nish removal, using the least amount of
water needed for eective rinsing.
5. Adjust the machine speed as required.
