Operator Cab and Controls - Section 32 08/11 OM3212 Page 32-18 Engine cooling water temperature gauge (4, Figure 32-8) indicates the temperature of the cooling water. If the temperature is normal during operation, the green range will light. If the red range lights during operation, the alarm buzzer will sound, the central warning lamp will flash and the coolant temperature monitor lamp will flash at the same time. If this occurs, stop the machine and operate the engine with no load at 1200-1500 rpm until the green range lights.
Engine Cooling Water Temperature Gauge Retarder Oil Temperature Gauge Retarder oil temperature gauge (8, Figure 32-8) indi- cates the temperature of the retarder cooling oil. Dur- ing normal operation, the green range should be illuminated. If the lamp in the red range illuminates during opera- tion, the alarm buzzer will sound, the central warning lamp will flash, and the retarder oil temperature mon- itor lamp will flash at the same time. If this happens, stop the machine, return the transmission range selector lever to NEUTRAL, and run the engine at 1200-1500 rpm under no load, and wait until the lamps in the green range illuminate.
Torque Converter Oil Temperature Monitor Torque converter oil temperature moni- tor (5, Figure 32-8) indicates a rise in the torque converter oil temperature. Left Turn Signal Pilot Lamp When the turn signal lever is moved downward, left turn signal pilot lamp (9, Figure 32-8) flashes. When the monitor lamp flashes, stop the machine and run the engine with no load at 1200-1500 rpm until the green range of the temperature gauge lights. High Beam Pilot Lamp High beam pilot lamp (10, Figure 32-8) lights up when the head lamps are on high beam. Torque Converter Oil Temperature Gauge Torque converter oil temperature gauge (6, Figure 32-8) indicates the temperature of the torque con- verter oil.
If the temperature is normal during opera- tion, the green range will light. If the red range lights during operation, the alarm buzzer will sound, the central warning lamp will light up and the torque con- verter oil temperature monitor lamp will flash at the same time. If this occurs, stop the machine and run the engine with no load at 1200-1500 rpm until the green range lights. Right Turn Signal Pilot Lamp When the turn signal lever is moved upward, right turn signal pilot lamp (11, Figure 32-8) flashes. Retarder Oil Temperature Monitor Speedometer Digital speedometer (12, Figure 32-8) indicates the travel speed of the truck in miles per hour, or kilo- meters per hour.
This fig- ure will appear momentarily when the keyswitch is first turned ON to demonstrate that all segments are working. Retarder oil temperature monitor lamp (7, Figure 32-8) indicates the retarder oil temperature has risen. If it flashes, stop the machine, return the transmis- sion range selector lever to NEUTRAL, and run the engine under no load at 1200-1500 rpm until the warning lamp goes out.
