OM3241 Operation - Section 32 Operator Cab and Controls Page 32-19 Electric System Fault Warning Electric system fault warning light (D1) 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, the propul- sion will be dropped automatically. Reset by pushing the override but- ton. If the fault repeats again, stop the truck and report the problem to maintenance personnel.

Low Automatic Lubrication System Pressure Amber low automatic lubrica- tion system pressure light (B2) will illuminate if the automatic lubrication system fails to reach 2,000 psi (15168 kPa) 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 maintenance personnel at the earliest opportunity after the light comes on. 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 over- ride switch.

If this occurs, notify maintenance person- nel immediately. Circuit Breaker Tripped Circuit breaker tripped light (C2) will illuminate if any of the circuit breakers in the relay circuit con- trol boards are tripped. The relay circuit boards are located in the electrical control cabinet. Low Brake Pressure Indicator Red low brake pressure indica- tor light (E1) indicates a mal- function within the hydraulic brake circuit. If this light comes on and the buzzer sounds, shut off the truck and notify maintenance personnel. NOTE: Additional circuit breakers are located in the operator cab behind the center console. However, tripping of these circuit breakers will not activate this light. NOTE:

Adequate hydraulic fluid is stored to allow the operator to safely stop the truck. Hydraulic Oil Filter Hydraulic oil filter light (D2) indi- cates a restriction in the high pressure filter assembly for either the steering or hoist circuit. This light will illuminate before the fil- ters start to bypass. Notify main- tenance personnel at the earliest opportunity after the light illuminates. Low Hydraulic Tank Level Low hydraulic tank level light (A2) indicates the oil level in the hydraulic tank is below the rec- ommended level. Damage to the hydraulic pumps may occur if operation continues. Shut the truck off and notify maintenance personnel immedi- ately. 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 has warmed, filter maintenance is not required.
