Normal Engine Operation
Observe gauges frequently to be sure all engine systems are functioning
properly.
The voltmeter shows the “charge/discharge” state of the battery charging system.
With the engine running, meter should indicate 13.5 to 14 volts. With engine
stopped, meter indicates battery charge (12 volts). The alternator indicator
light glows (red) to indicate alternator is not charging.
Be alert for unusual noises or vibration. When an unusual condition is noticed,
park machine in safe position and perform standard shut-down procedure.
(See Page 1.1) Report condition to your supervisor or maintenance
personnel.
Avoid prolonged idling. Idling causes engine temperature to drop and this
permits formation of heavy carbon deposits and dilution of lubricating oil by
incompletely-burned fuel. If the engine is not being used, turn it off.
Stopping the Engine
• To stop engine, perform standard shut-down procedure.
• Operate engine at low idle for 3 to 5 minutes before turning it off. This
allows engine coolant and lubricating oil to carry excessive heat away from
critical engine areas, including turbocharger.
• Do not “gun” engine before shut down: This practice causes incompletely
burned fuel to remove oil film from cylinder walls and dilute lubricant in
crankcase.
6.1
Always keep engine cover closed
while engine is running.
