FILL THE SOLUTION TANK
Open the Solution Tank Fill Cap (41) then fill the tank with a maximum of 14 US gallons (53 liters) of cleaning solution. The amount of solution in
the tank can be observed by looking at the Solution Tank Level Sight Tube (38).
The machine is equipped with EcoFlex a detergent dispensing system. When using this system the solution tank should be filled with plain water.
The machine can also be used conventionally with detergent mixed with water in the tank. Always follow the dilution instructions on the detergent
container label. The solution should be a mixture of water and the proper cleaning detergent for the job.
CAUTION!
Use only low-foaming, non-flammable liquid detergents intended for automatic scrubber machine applications. Water temperature
should not exceed 130 degrees Fahrenheit (55 degrees Celsius).
NOTE: When refilling the solution tank always empty the recovery tank using Recovery Tank Drain Hose (37).
SOLUTION TANK INDICATOR
See Figure 2-7. The solution pump can sense when there is no solution present and send a signal that the solution tank is empty. Once the tank
is empty the Solution Empty Indicator (X23) will flash on the display.
