The electric system fault warn-
ing light will flash on and off
when a malfunction occurs in
the electrical system.
warning horn will also sound
intermittently. When the light
illuminates, propulsion will be
dropped automatically. Reset
by pushing the override button. If the fault occurs
again, the truck should be stopped and the problem
investigated.
NOTE: The STATEX III system records the number
of faults (events) that occur during operation. When
the number of allowable faults (events) recorded
within a given time frame has been exceeded, the
operator will not be able to reset the system using the
override switch. Refer to Section E for information
regarding troubleshooting and determining the cause
of the fault.
E1. Low Brake Pressure
This red light indicates a mal-
function within the hydraulic
brake circuit. If this light comes
on and the buzzer sounds,

R for electrical schematics.
NOTE: Additional circuit breakers are in the operator
cab behind the center console, however tripping of
these circuit breakers will not activate this light.
D2. Hydraulic Oil Filter Monitor
The filter monitor warning light
will illuminate if the hoist sys-
tem or steering system hydrau-

replacement is required. Actual
filter bypass will occur at 50 psi
(345 kPa). Refer to Section M
for filter element replacement.
NOTE: The filter monitor warning light may also
illuminate after the engine is initially started if the oil
