OPERATION Monitoring Engine Operation While the engine is operating, monitor the battery charge indicator light, the oil pressure and avoid excessive idling. FIRE To avoid injury from fire, keep all potential ignition sources away from diesel fuel, including open flames, sparks, and electrical resistance heating elements. Do not smoke when refueling. Battery Charge The battery charge indicator light (see Figure 25) must go out once the engine starts. 1. Shut down the engine. 2. Check the poly-V belt for tightness. 3. Do a load test on the batteries. Charge or replace the batteries as needed. 4. If necessary, visit the nearest authorized dealer to have the alternator voltage and output checked.
Figure 25 Battery Charge Indicator Light Oil Pressure If the indicator light comes on while the engine is running, do the following: When the engine has reached its normal operating temperature, the engine oil pressure must not drop below the following values: 36 psi (250 kPa) at rated speed 7 psi (50 kPa) at idling speed If oil pressure drops below these values, stop the engine and determine the cause. 36 All information subject to change without notice.
