Operation - Section 32 02/10 OM3237 Page 32-20 Operator Cab and Controls This amber light indicates a restriction in the high pressure fil- ter assembly for either the steer- ing or hoist circuit. This light will illuminate before filters start to bypass. Notify maintenance per- sonnel at earliest opportunity after the light illumi- nates. D2. Hydraulic Oil Filter Monitor D3. Dynamic Retarding This amber dynamic retarding indicator light illuminates when- ever the retarder pedal is oper- ated, RSC is activated, or the automatic overspeed retarding circuit is energized. It indicates that the dynamic retarding func- tion of the truck is being used. 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. E3. Stop Engine Red stop engine warning light will illuminate if a serious engine malfunction is detected in the electronic engine control sys- tem. Electric propulsion to the wheel motors will be discontin- ued, and the maximum engine speed will be reduced to 1,250 rpm. Dynamic retarding will still be available if needed to slow or stop the truck. E2. Low Fuel This amber low fuel indicator light will illuminate when the usable fuel remaining in the tank is approximately 95 liters (25 gallons).
A warning buzzer will also sound. Electric propulsion to the wheelmotors will be discontinued. Dynamic retarding will still be available if needed to slow or stop the truck. A3. Parking Brake Amber parking brake indicator light will illuminate when the parking brake is applied. DO NOT attempt to drive the truck with the parking brake applied. 1. Stop the truck as quickly as possible in a safe area and shift to PARK. 2. PULL UP ON THE ENGINE STOP SWITCH ON THE CENTER CONSOLE TO STOP THE ENGINE, THEN TURN THE KEY SWITCH OFF. Additional engine damage is likely to occur if operation is continued. Notify maintenance personnel immediately. B3.
Service Brake This amber service brake indica- tor light will illuminate when the service brake pedal is applied or when wheel brake lock is applied. DO NOT attempt to drive the truck from stopped position with the service brakes applied. Listed below are a few conditions that could cause the stop engine light to illuminate: Low Oil Pressure - red warning light will illuminate, but the engine does not stop. Low Coolant Level - red warning light will illuminate, but the engine does not stop. C3. Body Up Low Coolant Pressure - red warning light will illuminate, but the engine does not stop. High Coolant Temperature - red warning light will illu- minate, but the engine does not stop.
This amber body up indicator, when illuminated, indicates that the body is not completely down on the frame. The truck must not be driven until body is down and the light is off.
