GENERAL MACHINE TROUBLESHOOTING

OPERATOR DISPLAY PANEL OVERLOAD INDICATORS:

There are (3) overload indicator lights, refer to the illustrations on pages (A-4 – A-5) for their locations.
Drive Motor Overload: This indicator (28) will flash RED along with the Main Power Indicator Light (25) if the wheel drive circuit breaker trips (Drive motor stops
running). To clear, turn key switch (24) off and determine and correct the cause of the overload. Then reset the 40 Amp circuit breaker (20). NOTE: In addition,
the Speed Control Status Indicator Light (27) will flash a green fault code (see Speed Control Status Light section below).
Lift Motor (Actuator) Overload: This indicator (29) will flash RED along with the Main Power Indicator Light (25) if a motor over load occurs. To clear, turn key
switch off, determine and correct the cause of the overload. Then turn key switch back on.
Pad Motor Overload: This indicator (30) will flash RED along with the Main Power Indicator Light (25) if a motor over load occurs. To clear, turn key switch off,
determine and correct the cause of the overload. Then turn key switch back on.

OPERATOR DISPLAY PANEL STATUS LIGHTS:

Speed Control Status Light: This indicator (27) will light GREEN when there is power applied to the control circuit of the speed controller (normal function). Note:
For the indictor to function the operator must be on the seat so that the seat switch is closed. The indicator will flash a diagnostic fault code to signal a drive controller
function problem. Have a qualified service mechanic refer to the machine service manual for explanations of the fault codes and corrective action for drive system
troubleshooting and repair.
Main Power Indicator Light (25) and Main Controller Fault Display (26): With the key turned on a GREEN light indicates the main controller system is ready.
A Green flashing indicator light shows that the key is turned off but the main controller is still maintaining power until the burnishing deck is automatically raised
to its full up position (normal function). When the light reads RED the pad motor well not function and at the same time an error code is displayed on the Hour
meter/Fault Display (26). This confirms a system error has occurred, the error display will read "Err" followed by a two digit code(s). Reference the Service Manual
for fault code descriptions and corrective action.
