Begin scrubbing by moving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75
mm). Adjust when necessary the machine speed and solution flow according to the condition of the floor.

can be changed to allow variable solution flow for different types of floors to be scrubbed. Example: A rough or absorbent floor surface,
such as unfinished concrete, well require more solution than a smooth finished floor.

To avoid damaging the floor, keep the machine moving while the brushes are turning.
10 10 10 10 10 When scrubbing, check behind the machine occasionally to see that all of the waste water 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 require adjustment.
11 11 11 11 11 For extremely dirty floors, a one-pass scrubbing operation may not be satisfactory and a "double-scrub" operation may be required. This
operation is the same as a one-pass scrubbing except on the first pass the squeegee is in the up position and the vacuum is turned OFF.
This allows the cleaning solution to remain on the floor to work longer. The final pass is made over the same area, with the squeegee
lowered to pick up the accumulated solution.
12 12 12 12 12 The recovery tank has an automatic float shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When
the float shut-off is activated, the control system will shut down the scrub, vacuum and solution systems. The Scrub Pressure Hourmeter
Display (A) (A) (A) (A) (A) will display "FULL". To clear the display, press the Scrub OFF Button (H)
the float closes, the recovery tank must be emptied. The machine will not pick up water with the float closed. NOTE:
repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a qualified service technician
refer to the service manual to perform this function.
13 13 13 13 13 When the operator wants to stop scrubbing or the recovery tank is full, press and hold the Scrub OFF Button (H)
"0". This will automatically stop the scrub brushes and solution flow and the scrub deck will raise UP. NOTE:
be turned off when the button is only pressed once, this is to allow any remaining water to be picked up without turning the vacuum back
on. Press the Scrub OFF Button (H)

Move the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, remove the Drain Hose (5)

water). Refill the solution tank and continue scrubbing.
