TROUBLESHOOTING
FAULTS
When a fault occurs, the trowel’s horn will begin a repeating
cycle of 5 beeps every 30 seconds. The amber LEDs on
the diagnostic display will turn ON (Figure 57), and the
Check Engine icon will be shown on the display. When
this happens:
1. Press the button on the right side of the display to view
the active fault code (Figure 58).
Figure 57. Diagnostic Display (Active Fault)
Figure 58. Diagnostic Display (Fault Code Screen)
2. Shut down the engines and correct the problem.
Until the fault has been cleared and machine power has
been restored, the horn’s beeping cycle will continue to
repeat while the engines are running or the ignition key is
in the ON position.

Fault codes shown on the diagnostic display are primarily
for machine faults. The only engine faults that are shown
on the display are related to engine oil temperature. For a
complete list of fault codes that are shown on the display,
see Table 10.
NOTICE
NEVER disable or disconnect the horn. Serious
damage to the trowel may occur as a result.
