2-12. Starting Procedures.
a.
Diesel Engine. (figure 2-4)
(1)
Ensure power take-off control lever (1) is in position closest to engine.
(2)
Ensure STOP control (2) is fully in.
WARNING
Operation of the equipment presents a noise hazard to personnel in the area. The
noise level exceeds the allowable limits for unprotected personnel. Wear ear
muffs or ear plugs which were fitted by a trained professional.
It is the diving supervisor's responsibility to ensure that exhaust fumes do not
enter the air intake on the compressor. Engine exhaust should always be down
wind, elevated, or piped overboard. Failure to prevent this may result in injury or
death to diver.
CAUTION
If engine fails to start within 30 seconds, release the start button. Allow the
starting motor to cool a few minutes before starting again. If the engine fails to
start after four attempts, an inspection should be made to determine the cause.
(3) Depress START button (3) and release when engine starts.
(4) Check engine oil pressure gage (4) after engine starts. Oil pressure should be at least 18 psi at 1200 rpm.
CAUTION
Avoid unnecessary engine idling. When prolonged idle is necessary, maintain at
least 800 rpm. Long periods of idle allow the water coolant temperatures to drop
below normal which causes incomplete fuel combustion, which in turn causes
dilution in the crankcase, this also allows formation of lacquer or gummy deposits
on valves, pistons and rings. There is also a rapid accumulation of sludge in the
engine.
(5) Allow engine to run at part throttle and no-load for approximately five minutes to warm up engine.
(6) Check engine coolant temperature gage (5). Normal operating temperature is 160-1850F.
