SCRUBBING
1
Push the Hopper Raise/Lower Switch
(18)
to the DOWN position to make sure the hopper is seated properly.
2
Put the Scrub Brush Switch
(7)
in the DOWN (ON) position. The brush drive assembly will lower to the floor and the brush motor will start
automatically.
3
Position the Solution Control Lever
(11)
half-way toward the front of its slot and drive the machine forward with the squeegee up. Then stop
the machine and look at the scrubbed area. There should be a thin, even layer of solution on the floor behind the machine. If there are dry spots
in the scrubbing path, push the lever forward for more solution. If the path of water on the floor is wider than the machine, pull the lever back
for less solution. Once you find the best solution flow, note the position of the Solution Control Lever for future reference.
4
Lower the squeegee
(9).
5
Begin scrubbing with a slow, even forward pedal pressure. Overlap passes 6 inches (15 cm). Turns may be made with all functions operating.
When backing up, the squeegee will raise automatically to prevent squeegee blade damage. You may want to shut the solution flow OFF to
prevent solution accumulation on turns.
Drive the machine forward at a normal walking speed for normal scrubbing. If the floor is still dirty behind the machine, drive slower. For very
dirty floors, “double scrubbing” may be necessary. Double scrubbing is the same as normal operation, only the squeegee is left in the up position.
This allows the cleaning solution more time to work on the floor. Then make a second pass with the squeegee down to scrub again and pick
up the solution. Do not “double scrub” too large of an area, or the solution will dry on the floor before the second pass.
Check behind the machine occasionally to see if all the solution is being picked up. If there is water trailing the machine you may be dispensing
too much solution, the recovery tank may be full or the squeegee tool may need adjustment. Note: The recovery tank has an automatic float
shut- off to block the vacuum system. You can tell when the float closes by the sudden change in the sound of the vacuum impeller. When
the float closes, the recovery tank must be emptied. The machine will not pick up water with the float closed.
6
With a full recovery tank, Turn off the solution flow, raise the scrub brushes, the squeegee and the sweeping broom. Then drive the machine
to a proper disposal site to empty the recovery tank.

EMPTYING THE RECOVERY TANK
1
Drive the machine to a proper disposal site.
2
Remove the drain hose from its storage compartment (lower right side of machine, behind main broom access door).
3
Direct the hose to a proper disposal site, remove the drain plug.
4
Flush the tank and drain hose with clean water.
5
Put the plug back into the hose and return the hose to its storage compartment.
