– If the solution system is off, the detergent pump will not turn on.
•
Vacuum/Wand Switch
– functions as follows:
– If the machine is in the Auto Scrub mode, pressing this switch once will raise the squeegee. The
vacuum motors will run for a short time delay, then shut off. If you press the switch twice, the vacuum
motors will shut off immediately. This is used if you wish to double-scrub (scrub without recovering the
solution).
– If the scrub system is off, the Vacuum/Wand Switch functions differently depending on whether the
seat switch is open (no operator in the seat) or closed (operator in the seat).
◦ If the operator is in the seat, pressing the switch will lower the squeegee and switch on the vacuum
motors. When the machine is moved into reverse, the squeegee will be raised, then lowered when
the machine is again moved forward. This mode is used to pickup water from the floor without
scrubbing or adding solution.
◦ If the operator is not in the seat, pressing the switch will toggle the vacuum motors on and off
to allow use of the vacuum wand. In this mode, the squeegee will not move up or down and the
recovery tank full indicator is ignored.
•
Scrub Speed Switch
– When the machine is operating in any one of its scrub settings, the machine’s travel
speed is reduced to 80 percent of the maximum transport speed pre-programmed into the speed controller.
Pressing the Scrub Speed Switch overrides the 80 percent of transport speed limit and increases the scrub
speed to 100 percent of transport speed.
•
Traction Control Switch
– regulates the drive wheel motor torque to minimize drive wheel slippage in
limited traction conditions.
•
Side Broom On/Down Switch
– lowers and raises the side brooms (only functional on cylindrical models
equipped with side brooms). Note that when the scrub system is switched on, the side brooms are lowered
to the same position they were in when the scrub system was last turned off (auto memory operating
position).
Note: You can raise or lower the side broom height to maintain the correct broom contact patterns
and compensate for normal broom wear. Refer to the
Sweep System, Side Broom
section for
instructions on setting the side broom height.
•
Burst of Power Button
– The
Burst of Power Button
functions differently depending on whether the EcoFlex
™
mode is set to Mode 1 or Mode 2. (Also refer to the
Control System/Main Programming Options/
EcoFlex™ Mode Selection
section.) Note that in Mode 1 the detergent concentration is displayed as a
ratio. In Mode 2 the detergent concentration is displayed as a percent.
– In EcoFlex
™
Mode 1, the minimum detergent concentration is displayed as a ratio. Pressing the
Burst of
Power Button
in Mode 1 will do the following:
◦ The detergent ratio will change to the maximum concentration programmed ratio. (Also refer to the
Solution System/Maintenance and Adjustments/To Program the Detergent Ratio
section.)
◦ The scrub pressure will increase to the next highest pressure.
◦ The solution flow rate will increase to the next highest level.
After 60 seconds, or after you press the
Burst of Power Button
again, the detergent ratio will revert
to the minimum concentration ratio, and the scrub pressure and solution rate will return to their
previous settings.
