After warming unit, check all operating indicators to make
sure that all engine systems (oil pressure, coolant, etc.) are
in the normal operating range. If any problems are noticed,
stop engine and correct the problem.
Normal indicators are:
10. Check color of exhaust smoke.
•
No color or light blue - Engine is running in good
condition.
•
Black - Incomplete combustion. Check cause.
•
White or dark blue - Engine is burning engine oil.
Check cause.
11. Check for usual engine vibration and noises. If any are
heard or felt, investigate cause.
NOTE:
If engine coolant temperature gauge pointer moves
into the red zone, the engine coolant temperature
warning light will turn "ON", a warning buzzer will
sound, and the engine speed will be automatically
reduced. Allow the engine to run at low idle speed
until temperature gauge registers in the white zone
again. When the white zone is reached, allow the
engine to idle for an additional three - five (3 - 5)
minutes before stopping the engine. If not allowed
to idle, heat surge may develop which will damage
the engine. Allowing the engine to idle will dissipate
heat. Check the coolant level, look for a loose fan
belt, inspect for debris around radiator, etc.
12. Even if the engine starts, wait for the engine oil pressure
monitor light to turn "OFF". Do not touch the control levers or
control pedal while the engine oil pressure monitor light is "ON".

NOTICE
If the engine oil pressure monitor light does not turn
"OFF", after 4 to 5 seconds have passed, stop engine
immediately. Check the oil level, check for leakage of
oil, and take necessary corrective action.
