OM3223 Operation - Section 32
Operator Cab and Controls Page 32-19
D1. Electric System Fault
The electric system fault warning
light will flash on and off when a
malfunction occurs in the electri-
cal system. The warning horn will
also sound intermittently. When
the light comes on, propulsion
will be reduced automatically.
Reset by pushing override but-
ton. If the fault repeats again, stop the truck and
report the problem to maintenance personnel.
NOTE: STATEX III records the number of faults/
events. When a predetermined number of faults/
events are recorded within a given time frame, the
operator will not be able to reset the fault/event by
using the override switch. If this occurs, notify main-
tenance personnel immediately.
E1. Low Brake Pressure
This red indicator light indicates
a malfunction within the hydrau-
lic brake circuit. If this light
comes on and the buzzer
sounds, shut down truck opera-
tion and notify maintenance
personnel.
NOTE: Adequate hydraulic fluid is stored to allow the
operator to safely stop the truck.
A2. Low Hydraulic Tank Level
This warning light indicates the
oil level in the hydraulic tank is
below recommended level. Dam-
age to hydraulic pumps may
occur if operation continues.
Shut truck down and notify main-
tenance personnel immediately.
B2. Low Automatic
Lubrication System Pressure
This amber light will illuminate if
the automatic lubrication sys-
tem fails to reach 2,200 psi (at
the junction block located on
the rear axle housing) within
one minute after the lube timer
indicates a cycle of grease. To turn the light off, turn
the key switch off, then back on again. Notify mainte-
nance personnel at earliest opportunity after the light
comes on.
C2. Circuit Breaker Tripped
This light will illuminate if any of
the circuit breakers in the relay
circuit control boards are tripped.
The relay circuit boards are
located in the electrical control
cabinet.
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
This light indicates a restriction in
the high pressure filter assembly
for either the steering or hoist cir-
cuit. This light will illuminate
before filters start to bypass.
Notify maintenance personnel at
the earliest opportunity after the light comes on.
NOTE: The filter monitor warning light may also
illuminate after the engine is initially started if the oil
is cold. If the light turns off after the oil is warmed,
filter maintenance is not required.
E2. Low Fuel Indicator
This amber low fuel indicator
will illuminate when the usable
fuel remaining in the tank is
approximately 95 liters (25 gal-
lons). A warning buzzer will also
sound.
A3. Parking Brake
This amber parking brake indica-
tor will illuminate when the park-
ing brake is applied. Do not
attempt to drive the truck with the
parking brake applied.
B3. Service Brake
This amber service brake indica-
tor light will illuminate when the
service brake pedal is applied or
when wheel brake lock or emer-
gency brake is applied. Do not
attempt to drive the truck from
the stopped position with the
service brakes applied.
