Engine Operation Monitoring the Engine Operation While the engine is operating, monitor the instrument panel indicators, battery charge indicator and the oil pressure. Unnecessary idling should be avoided whenever possible. When prolonged idling is necessary, maintain an engine speed of 900 rpm. Monitoring the Oil Pressure When the engine has reached its normal operating temperature, the engine oil pressure must not drop below the normal operating range. If oil pressure drops below the normal operating range or if an oil pressure warning indicator becomes active, stop the engine and determine the cause. It may be necessary to take the vehicle to an authorized Detroit™ service outlet.
Monitoring the Instrument Panel During engine operation, monitor the instrument panel and instrument panel indicators for any warnings or messages concerning the vehicle's operating status. The instrument panel will display engine speed, vehicle speed, as well as alert the driver of various temperatures, pressures and other vehicle conditions. For more information, Refer to section "Instrument Panel Indicators". If the instrument panel indicates a malfunction, the operator is responsible to take action to avoid equipment damage. Monitoring the Battery Charging System The battery charge indicator must turn off once the engine starts.
If the indicator comes on while the engine is running, do the following: 1. Shut down the engine. 2. Have the charging system and batteries tested. Authorized Detroit™ service outlets are properly equipped for these types of service Shifting a Manual Transmission Shifting a Manual Transmission Depending on the transmission model, the gear split may vary from 400 to 500 rpm. The electronic governor provides almost no overrun capability and if the transmission is downshifted too early, a temporary loss of pulling power will be experienced until the engine speed falls below rated speed. 30 All information subject to change without notice.
