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. Solution flow, floor surface, and down-pressure
should be considered when operating the machine (example: high down-pressure on a rough floor with no solution flow
will overload the circuit). Repeatedly tripping the breaker will cause the need for replacement.
BATTERY POWER LEVEL AND 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 flash and the brush motor will
turn off. The vacuum and traction drive will continue to function allowing final 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 full charge, operate the machine for at least 30 minutes before recharging the batteries. Do not leave the
batteries discharged overnight
A Flashing Battery Power Level Indicator indicates a detected fault. The following is a list of fault codes:
The battery needs to be charged or there is a faulty connection to the battery
Check the connection to the motor
The motor has a short circuit
Not used
Not used
The controller is being inhibited from driving
Throttle fault, check the connection
Controller fault, check connections
Parking brake fault, check the motor connections
Excessive voltage, check the battery connections

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 front/back and left/right alignment
CHEMICAL-FREE FINISH REMOVAL:
The addition of a specialized surface preparation pad in addition to the traditional cleaning pad is required for chemical-free
finish removal. The traditional pad acts as a “backer pad” and compensates for variances in the floor
1. Leave a 2” gap along the front of the machine so water can fully saturate the pad
2. Align the Velcro pad retainer along one length of the red, backer pad and press down
3. Place the surface prep pad on top of the pad retainer, centering it with the red pad
4. See steps 1-3 of “Standard Cleaning Operations” above

9. RECOVERY SYSTEM
RECOVERY TANK
To drain and rinse the recovery tank:
1. Lift the hose off the holder and lower the hose end to the desired drain location
2. Remove the press-fit cap from the drain hose and squeeze the restriction collar to control the flow
3. As the tank drains, lift the recovery tank lid to the fully open position
4. Thoroughly clean and rinse out the sediment from the bottom of the tank with a clean water hose
•Periodically use cleaner and sanitizer with a cloth or sponge to prevent mold and mildew
5. Inspect and clean the debris tray and the vacuum mesh filter screen and ball float system
6. Leave the lid open to dry
OPTIONAL TANK TREATMENT
The Tank Treatment System (TTS) utilizes Bromine tablets, (typically used in pools and spas) to kill the odor-causing
bacteria in the tank. To ensure that TTS is prepared to treat your recovery tank:
1. Lift the debris tray out and pinch the two tabs sticking through the underside of the tray
2. Check the size of the Bromine puck. Replace when it is approximately 25% of its original size
3. Press the TTS holder and bromine puck back into the debris tray
CAUTION: Use Bromine only! Do not use chlorine. Chlorine can interact with ammonia-based detergents to cause
harmful fumes
