Screen 1 is the default screen that appears after the machine
has powered up.
1: BATTERY METER - This meter shows the charge level of
the batteries in the machine. This gauge is designed to read
properly while the machine is in use and therefore will vary up
and down during usage of the machine.
2: BRUSHES RUNNING - This icon shows when the controller
receives an input to run the scrub brushes.
3: SOLUTION DISPENSING - This icon indicates that the con-
troller is receiving an input to dispense water. The icon flashes
in relationship to the amount of time the valve is on for. This is
controlled by the solution potentiometer on the control panel.
4: BRUSH PRESSURE GAUGE - This icon is a bar graph
representation of the desired brush pressure. It is divided into
5 segments and each segment indicates more pad pressure.
5: VACUUM MOTOR - This icon indicates the controller is
receiving an input to run the vacuum motor.
6: HIGH THROTTLE - This icon indicates one or more throttle
inputs, such as the green handle bar buttons or the reverse
switch, were activated when the machine was powered on.
To clear this icon make sure no buttons or switches are de-
pressed and cycle the power to the machine.
