To operate thesqueegee, follow this procedure:1. To lower the squeegee and start the vacuum motor,press the squeegee up/down switch to the downposition (figure 24). NOTE: The vacuum motorwill start immediately when the down positionof the switch is pressed, and the squeegee willlower.2. To raise the squeegee, press the squeegee up/down switch to the up position (figure 24). Thesqueegee will then raise and the vacuum motor willshut off after short delay NOTE: The centerposition of the squeegee up/down switch is foruse with one touch control.NOTE: The squeegee will rise automatically whentraversing in reverse during scrubbing operations.How to Operate the Solution FlowThe solution is used to loosen and remove dirt from the floor.The amount of solution applied can be adjusted to fivedifferent levels to accommodate many different floorconditions. These different levels are shown on the LCDdisplay on the front of the machine. To adjust the amountof solution applied, use the Solution Flow Switch (figure 25).NOTE: There are five different settings on the display.See figure 26, A.To increase solution flow:1. Press the “ + ” side of the switch (figure 25).2. Press and hold the “ + ” switch to achieve the desiredlevel of solution flow.To decrease solution flow:. 1. Press the “ - “ side of the switch (figure 25).2. Press and hold the “ - “ side of the switch to achieve thedesired level of solution flow.How to Operate the Brush PressureThe brushes are used to supply agitation for the solution,which improves the cleaning process. The amount of brushpressure applied can be adjusted to five different levels toaccommodate many different floor conditions. Thesedifferent levels are shown on the LCD display on the front ofthe machine (figure 26, B). To adjust the amount of brushpressure, use the brush up/down switch (figure 27).To increase brush pressure:1. Press the “ + ” side of the switch (figure 27).2. Press and hold the “ + ” switch to achieve maximumlevel of pressure.To decrease brush pressure:. 1. Press the “ - “ side of the switch (figure 27).2. Press and hold the “ - “ side of the switch to achieveminimum or no brush presssure.Figure 24Figure 25Figure 26Figure 27How To Operate the MachineAB
