MAN — Running the Engine

Operating Instructions for Starting the Engine 3. Wait for the engine system indicator lights on the instrument panel to go out. 4. With foot off the accelerator pedal, start the engine. 5. If the engine does not start after 20 seconds, stop. Try again after waiting about 60 seconds. NOTICE: Do not increase engine speed if the oil pressure gauge indicates no oil pressure. Shut down the engine within approximately ten seconds to avoid engine damage. Check to determine the cause of the problem. NOTE: Do not place the engine under full load until it reaches operating temperature. Colder engine temperatures will cause the engine to preset idle up to 900 rpm.

Even at a high idle condition, you do not have to wait for engine warm up and return to normal 600 rpm idle to drive the truck. 6. Monitor the oil pressure gauge immediately after starting the engine. Running the Engine While the engine is operating, monitor the battery charge indicator light, the oil pressure, and avoid excessive idling. Checking the Oil Pressure Monitor the oil pressure as follows: WARNING: HOT OIL To avoid injury from hot oil, do not operate the engine with the rocker cover(s) removed. 1. Observe the oil pressure gauge immediately after starting the engine.

An oil pressure gauge that registers pressure 14 psi (96 kPa) at idle speed and normal operating temperature is a good indicator that all moving parts are getting lubrication. 2. If no pressure is indicated within 10 to 15 seconds, stop the engine and check the lubrication system at normal operating temperature. 3. The oil pressure should not drop below 55 psi (380 kPa) at 1800 rpm, at normal operating temperature. If oil pressure does not fall within these guidelines, check it with a manual gauge. Warming Up the Engine Run the engine at part throttle for about five minutes to allow it to warm up before applying a load. 28 All information subject to change without notice.
