◦ If the direction is forward, the solution and detergent flow will also start automatically.
◦ If the direction is reverse, the solution and detergent flow will be stopped and the squeegee will be
raised just enough to clear the floor surface.
Note:
The solution, vacuum and detergent systems are automatically enabled when the
Scrub On
Switch
is pressed to put the machine into the Auto Scrub mode. Any individual system can
be toggled off and on by simply pressing the corresponding system switch at any time during
scrubbing.
If the machine is already scrubbing, pressing the
Scrub On/Pressure Increase Switch
will increase the
scrub pressure
to the next higher setting (toggling from regular to heavy, heavy to extreme, then back to
normal). The
Scrub Pressure Indicator
will show the selected scrub pressure (one, two or three bars) in the
Control Panel Display
.
•
Scrub Off Switch
– Pressing this switch when the machine is in the scrub mode will cause the following to
occur:
–
The scrub brushes will turn off and the scrub deck will be raised to the up position. On cylindrical
models equipped with side brooms, the side brooms will shut off and be raised.
–
The solution and detergent flow will be stopped.
–
Once forward machine motion stops, the vacuum/wand switch indicator light will start to blink. After
a user-programmable time delay, the squeegee will be raised and the vacuum motors will shut off.
Pressing the switch a second time before the vacuum time delay is complete will raise the squeegee
and turn off the vacuum motors immediately.
•
Solution Switch
– functions as follows:
–
If the scrub system is off, pressing and holding this switch will switch on the solution flow to pre-
wet the floor. The solution flow will stop when the switch is released. Note this must be done prior to
pressing the
Scrub On Switch
and putting the machine into the Auto Scrub mode.
–
If the machine is in the Auto Scrub mode, pressing this switch will disable the solution system. This is
used if you wish to scrub without adding additional solution to the floor.
–
If the machine is in the Auto Scrub mode, you can press and hold the
Solution Switch
to actuate the
solution flow override function. This override function allows you to select a different solution flow rate
without changing the scrub pressure. Note that the machine is programmed for two additional higher
solution flow rates plus the three normal default flow rates, for a total of five solution flow rates.
To actuate the solution flow override function, press and hold the
Solution Switch
for three seconds until
the
Solution System Indicator
flashes, then release it. You’ll have three seconds to select the desired
solution flow rate by pressing the
Solution Switch
. The
Solution Flow Indicator
will show the selected
solution flow rate (one through five bars) in the
Control Panel Display
. Note that if any scrub pressure
change is made while in the solution override mode, the solution flow will return to its default solution
flow rate.
•
Detergent Switch
– functions as follows:
–
If the solution system is enabled, pressing this switch will toggle the detergent system off and on.
When the detergent system is on, the detergent pumps will be activated at a specific rate when the
drive pedal is actuated. The detergent pump will turn off when the drive pedal is in neutral or reverse.
