Operating the Truck
starting sequence. The engine pre-lube motor will run until engine oil pressure of
0.35 - 0.48 bar (5 - 7 lbf/in²) is achieved. This will normally take between
8 -15 seconds, but can take up to 45 seconds in cold climates or with dry filters.
After an interval of 3 seconds, the pre-lube motor stops and the engine starter
motors engage. Release the key as soon as the engine starts firing.
NOTICE
Never crank the engine more than 30 seconds continuously. Allow starter(s)
at least 2 minutes cooling time between cranking periods to avoid
overheating.
8. Check the engine oil pressure gauge. Within 10 to 15 seconds at engine idle,
the gauge needle should rise into the yellow zone. If the needle does not rise
within 15 seconds, shut off the engine and do not operate until the fault is
identified and corrected.
9. Observe the engine water temperature gauge. After a few minutes running
time at moderate load and varying speed, the gauge needle should be in the
green zone. If the needle moves into the red zone, the engine is over heated
and should be shut down immediately.
