2. Connect hose to tank. (See Figure 7)

OPERATION

FILL TANK

1. Add water and detergent into the tank. (See Figure 8)NOTE: Use a non-foaming detergent with a pH range between 7-11. Be sure to follow the detergent instructions for proper dilution.
2. Open flow from detergent tank by pushing lever up to horizontal position. Leave open. (See Figure 9)

2. Turn on unit and press brush button. All lights will light up and unit is fully functional. (See Figures 11 and 12)
3. After use, empty the recovery tank by using the attached drain hose. (See Figure 13)
4. Once finished, charge the battery.

NOTE: The battery should be charged after every use. For optimal battery life, leave plugged in when not in use.

MAINTENANCE

DAILY MAINTENANCE

1. Use the attached drain hose to empty the dirty water from the recovery tank. (See Figure 14)
2. Remove lid and check that dirty water tank float is undamaged, clean and moves freely on pin. (See Figures 15 and 16)
3. Lift off recovery tank to clean. (See Figure 17)
4. Clean brush and check squeegee is clean and blades are not damaged. (See Figure 18)
5. Check battery charge. (See Figure 19)
6. To recharge batteries, plug in battery charger using electrical cord provided with machine. Charge is complete when the green LED light is on. (See Figures 20 and 21)

REPLACING THE SQUEEGEE BLADE

1. Remove the squeegee assembly using the two black knobs.
2. Remove the squeegee blade by removing the screws, wing nuts and blade retainers. (See Figure 22)
3. Reuse the same blade by reversing the edge in contact with the floor. The blades should be reused until all four edges are worn out and can be replaced at once.
4. Align the new (or reversed) blades with the tabs and screw holes on the squeegee body.
5. Reposition the two blade retainers, and insert the screws. Attach and tighten the wing nuts.

BRUSH REPLACEMENT

1. With the underside exposed, remove brush by rotating clockwise off the center hub.
2. Install new brush by rotating counterclockwise onto the center hub.

CHECK MOTOR FUSES

NOTE: Fuses need to be replaced with the correct value. Value is listed on the fuse.

• Main fuse (A) between batteries – 30 amp
• Brush motor (B) – 25 amp
• Vacuum motor (C) – 20 amp

1. Lift off recovery tank. (See Figure 23)
2. Locate fuses. (See Figure 24)
3. Pull off black caps from the brush motor fuse (B) and the vacuum motor fuse (C). (See Figures 25 and 26)
4. Check the fuse to see if it is blown by looking in the fuse window. If the metal wire is present and not broken, the fuse is good. If the metal wire is missing or broken, the fuse is bad and needs to be replaced with a new fuse. (See Figure 27)

TROUBLESHOOTING

OPERATING ISSUE	CAUSES	RECOMMENDATIONS
The machine does not work.	The batteries need to be charged.	Charge the batteries.
The brush does not rotate.	The brush button LED is off. The brush motor thermal cutout has tripped; the motor has overheated. The batteries need to be charged. The brush motor fuse has blown.	Press the brush button. Turn the unit off. Let the machine cool down for at least 45 minutes. Charge the batteries. Replace the brush motor fuse.
The machine does not clean evenly.	The brush or floor cleaning pad is worn.	Replace the worn brush or floor cleaning pad.

OPERATING ISSUE	CAUSES	RECOMMENDATIONS
No detergent is delivered.	The detergent button LED is off. The detergent tank is empty. The brush motor is off.   The hose delivering the detergent to the brush is blocked. The detergent tap is dirty or faulty.   The in-line filter is dirty (left side from operator’s position near the wheel).	Press the detergent button. Fill the detergent tank. Turn the motor on by pressing the brush button. Unblock and open the detergent tank tap. Have the detergent tap cleaned or replaced. Clean the filter. Make sure to close the detergent tap prior to cleaning.
The suction motor does not start.	The fan button LED is off. The vacuum motor fuse is blown.	Press the fan button. Replace the vacuum motor fuse.
The squeegee does not clean or has poor suction.	The edge of the squeegee blades in contact with the floor is worn. The squeegee or hose is blocked or damaged. The float switch has tripped (dirty water drum), is clogged by dirt or broken. The suction hose is blocked. The suction hose is not connected to the squeegee or is damaged. Debris is trapped between the squeegee blades.	Replace the squeegee blades.   Unblock and repair the damage.   Empty the recovery tank or reset the float switch.   Unblock the hose. Connect or repair the hose.   Clean out debris from the squeegee blades.
The machine leaves stripes of wet floor.	Dust or debris on the floor is catching on the squeegee blades. Debris is trapped between the squeegee blades. The squeegee blades are worn.	Sweep the floor prior to using the machine. Clean out debris from the squeegee blades. Replace the squeegee blades.
The batteries do not provide the nominal work time.	The battery charger is not working.	See battery charging instructions.
The battery discharges too fast during use, even though it has been charged correctly.	The battery is new and does not deliver 100% of its expected capacity.	This is normal. New batteries require a break-in period of approximately 10 charging cycles. Unplug unit and use as normal. Charge after use.
