SERVICING LEAD ACID BATTERIES WITH HYDROLINK® WATERING
SYSTEM
1. Position the container of distilled water below the level of the top of the batteries to prevent siphoning.
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, disconnect the coupler 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.

Inspect the Brake System. Ensure the brake is functioning properly. Check all associated connectors and wiring.
Excessive voltage has been applied to the control system. This is usually caused by a poor battery connection. Check
the battery connections.
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 surface, 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 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 DISTRIBUTION
FILLING THE SOLUTION TANK
SOLUTION FLOW
DRIVE SYSTEM (TRACTION MODELS)
1. Turn the machine on using the key switch located on the right side of the steering column.
2. Set the desired maximum speed using the Speed Control selector on the Control Panel.
3. Maintain control of the machine at all times during operation.
4. Depress the Bail to engage the scrub head and drive system (on applicable models).
5. Depress the Reverse Button to drive the machine backwards (on applicable models).
Use liquid detergent in the concentration and manner specied by the manufacturer
for a 11-gallon solution tank. Excess foam will damage the vacuum motor. In addi-
tion to properly-mixed low-foam detergent, use a small amount of de-foaming liquid
in the recovery tank. Never use pure acids.
1. Add water and cleaning agent via the ll port located at the front of the machine.
Water should not exceed 120°F (50°C).
2. Monitor the level of the solution through the sight tube located at the rear of the
machine.
3. To drain the solution tank, slide the sight tube o of the upper tting and lower
the tube into drain or mop sink.
Solution ow is controlled by the Solution Flow Control located on the Control Panel. When the Scrub Head in lowered, solution is
delivered at a rate of 0 - 0.5 gpm (0 - 1.9 lpm) based upon the Solution Flow setting and the speed of the machine (ow rate increases
or decreases with machine speed to prevent over/under distribution).

INSPECTION & CLEANING
To clean out the solution tank in the case of excessive debris:
1. Close the shuto valve (located under the machine).
2. Remove the lter bowl and screen (located forward of the
shuto valve).
3. Open the shuto valve and allow the tank to drain.
4. Rinse the solution tank thoroughly.
5. Install the lter bowl and screen.
SCRUB HEAD
1. Depress the foot lever (located at the lower right rear corner of the machine) and shift it to the right.
2. Once clear of the notch, allow the lever to rise while the head lowers into the operating position.
3. Disk machines are equipped with a self-adjusting shroud and bristle skirt that virtually eliminates over-spray.
SELECTING DOWN PRESSURE
• Standard: For daily cleaning of normal soils.
• Heavy: For toughest soils or chemical-free nish removal.

ORBITAL SCRUB HEAD & CHEMICAL-FREE FINISH REMOVAL
NOTE: Do not operate the Orbital Scrub Head without a pad installed. Operating the head without a pad will damage the
Mighty-Lok® face.
STANDARD OPERATION
1. Align the corners of the pad to the corners of the aluminum plate with
Mighty-Lok® face and press to attach.
2. Lower the scrub deck onto the pad.
3. Ensure the pad is properly aligned front-to-back and right-to-left. Water
should drip directly onto the top of the pad.
CHEMICAL-FREE FINISH REMOVAL (CFR) PAD ASSEMBLY & OPERATION
In addition to the traditional cleaning pad, a specialized surface preparation pad is required for chemical-free nish removal. The
standard red scrub pad acts as a “backer” and compensates for variances in the oor.
1. Place the black retainer pad 2” back from the front of the red
scrub pad.
2. Align the maroon CFR pad with the red scrub pad.
3. Ensure the pads are aligned so that the black pad is justied
towards the back of the machine, so that the gap described in Step
1 is towards the front of the machine.
4. Install the pads in accordance with the instructions above for
standard operation.
5. Fill the Solution Tank with clean water.
6. Set the Solution Flow to the medium setting. Adjust as needed
to obtain the optimum nish removal using the least amount of
water for eective rinsing.
7. Set the Speed Control to the medium setting.
8. Lower the Scrub Head to the Heavy Down Pressure setting.
