How To Operate the Machine
How to Operate the Squeegee and the Vacuum Motor
The squeegee wipes the fl oor while the vacuum motor removes the dirty
solution from the fl oor. To operate the squeegee, follow this procedure:
1. To lower the squeegee and start the vacuum motor, press the squee-
gee up/down switch to the down position (fi gure 24). NOTE: The
vacuum motor will start immediately when the down position of
the switch is pressed, and the squeegee will lower.
2. To raise the squeegee, press the squeegee up/down switch to the up
position (fi gure 24). The squeegee will then raise and the vacuum
motor will shut off after short delay NOTE: The center position of
the squeegee up/down switch is for use with one touch control.
NOTE: The squeegee will rise automatically when traversing in reverse
during scrubbing operations.
How to Operate the Solution Flow
The solution is used to loosen and remove dirt from the fl oor. The amount
of solution applied can be adjusted to fi ve different levels to accommodate
many different fl oor conditions. These different levels are shown on the
LCD display on the front of the machine. To adjust the amount of solution
applied, use the Solution Flow Switch (fi gure 25). NOTE: There are fi ve
different settings on the display. See fi gure 26, A.
To increase solution fl ow:
1. Press the “ + ” side of the switch (fi gure 25).
2. Press and hold the “ + ” switch to achieve the desired level of solution
fl ow.
To decrease solution fl ow:
1. Press the “ - “ side of the switch (fi gure 25).
2. Press and hold the “ - “ side of the switch to achieve the desired level
of solution fl ow.
How to Operate the Brush Pressure
The brushes are used to supply agitation for the solution, which improves
the cleaning process. The amount of brush pressure applied can be ad-
justed to fi ve different levels to accommodate many different fl oor condi-
tions. These different levels are shown on the LCD display on the front of
the machine (fi gure 26, B). To adjust the amount of brush pressure, use the
brush up/down switch (fi gure 27).
To increase brush pressure:
1. Press the “ + ” side of the switch (fi gure 27).
2. Press and hold the “ + ” switch to achieve maximum level of pres-
sure.
To decrease brush pressure:
1. Press the “ - “ side of the switch (fi gure 27).
2. Press and hold the “ - “ side of the switch to achieve minimum or no
brush presssure.
