The following sections cover normal operations.
Ensure area is ventilated well before starting the engine.
To avoid injury from inhaling engine exhaust, always operate the engine in a well-ventilated area. Engine exhaust is toxic.
Run the engine at idle with no-load for approximately five minutes, allowing it to warm-up before applying a load. The engine will idle at a higher speed if the oil is cold when started.
As the engine reaches operating temperature, the electronic control system of the engine will lower the idle speed if not equipped with an automatic transmission.
If the unit is operating in a closed room, start the room ventilating fan or open the windows and doors, as weather conditions permit, so ample air is available for the engine.
While the engine is running at operating temperature, check for coolant, fuel or lubricating oil leaks. Tighten the line connections where necessary to stop leaks.
Observe the oil pressure gage immediately after starting the engine. If there is no pressure indicated within 10 to 15 seconds, or the stop engine light (red) comes on, stop the engine and check the lubricating oil system.
refer to "11.5 Operating Conditions"
for normal operating temperature.
If the engine crankcase was refilled, stop the engine after normal operating temperature has been reached, allow the oil to drain (approximately 20 minutes) back into the crankcase and check the oil level. Add oil, if necessary, to bring it to the proper level on the dipstick.
Use only the lubricating oil specified. Refer to "5.2 Lubricating Oil"
Several types of cooling systems are used by vehicle manufacturers. Refer to vehicle owner's manual for specific instructions.
To avoid injury from the expulsion of hot coolant, never remove the cooling system pressure cap while the engine is at operating temperature. Remove the cap slowly to relieve pressure. Wear adequate protective clothing (face shield or safety goggles, rubber gloves, apron, and boots).
Remove the radiator cap slowly and check the engine coolant level. The coolant level should be within two inches of the top of the opening. If necessary, add properly inhibited coolant.
Make a visual inspection of the turbocharger for leaks and excessive vibration. Stop the engine immediately if there is an unusual noise in the turbocharger.
Avoid Unnecessary Engine Idling
During long engine idling periods, the engine coolant temperature will fall below the normal operating range. The incomplete combustion of fuel in a cold engine will cause crankcase dilution, formation of lacquer or gummy deposits on the valves, pistons and rings and rapid accumulation of sludge in the engine.
Note: When prolonged engine idling is necessary, maintain at least 800 r/min.
