2. Place the end of the watering system hose in the distilled water and squeeze the
bulb to ll the system.
3. Remove the dust cover from the Hydrolink® snake connected to the batteries.
4. Connect the coupler on the Hydrolink® snake to the coupler on the watering
system using the quick disconnect ttings.
5. While squeezing the hand pump, observe the ow indicator (spinning red balls).
As the batteries begin to ll, the spinning of the ow indicator balls will slow.
Batteries are full when the ow indicators completely stop spinning.
NOTE: Battery systems may take more than 1/2 gallon of water once the
BatteryShield® light has illuminated. Failure to actuate the hand pump until
the ow indicator stops spinning will result in batteries being under or
unevenly serviced which will reduce battery life.
6. When the ow indicator stops, and not before, immediately disconnect the
couplers by depressing the push button on the watering system coupler.
NOTE: Leaving the watering system connected could result in the batteries being
over lled. Disconnecting the watering system before the ow indicator stops
spinning will result in batteries being under serviced and battery life will be
reduced.
7. Replace the dust cover on the Hydrolink® snake.

BATTERYSHIELD®AUTOMATED WET BATTERY PROTECTION
SYSTEM
Machines equipped with BatteryShield® technology have a sensor installed on one of the battery caps and a red
LED indicator located on the Control Panel. This sensor monitors the water level in the batteries and the LED
communicates to the operator that the batteries require servicing. When the BatteryShield® LED is lit, the scrub
head is disabled until battery servicing has been performed.
• When the key switch is turned on, the BatteryShield® system will check the water level of the batteries.
• If the LED turns o, there is sucient water in the batteries.
• If the LED remains on (without ashing), the batteries require servicing and the scrub head will not run.
• If the LED ashes intermittently, the BatteryShield® light pipe must be cleaned (instructions below).
NOTE: Failure to clean the BatteryShield® light pipe will limit the system’s ability to read the water level and
will reduce battery life.
• If the BatteryShield® LED indicates the need for servicing, turn o the key switch and service the batteries
as described above.
• After completing the Hydrolink® watering system procedure, turn the key switch back on and verify the
LED turns o.

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.
A ashing 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.
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.

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.
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.
