STARTING A COLD ENGINE

IMPORTANT: Always check all fluid levels before starting engine. Refer to

Maintenance Chart.

1. Turn on and run engine compartment bilge blower (if equipped) for five minutes. Or,

open engine hatch to air out bilge before attempting to start engine(s).

2. On D4.2L only: set cold start lever if temperature is less than 10 degrees C (50 degrees

F). Move lever in direction shown. Lever should be reset as soon as engine starts and

idles smoothly.

3. After a lengthy layup (several months or more) pre-lubricate the turbocharger and

engine. To do this, hold the STOP switch engaged while you simultaneously turn the key

switch to START position for 15 seconds. This will rotate the starter motor and engine/oil

pump. During this process the engine will not run because no fuel is injected. Allow the

starter motor to cool down for one minute and repeat the above described process. To

avoid overheating the starter motor, do not engage starter motor for more than 15

seconds each time. Proceed to next step after a slight increase in oil pressure is

observed.

4. If engine has not been run for a period of time and will not readily start with the standard

starting procedure, there is a hand pump/primer knob located on the fuel filter header.

Move knob up and down four or five strokes.

5. Turn key switch to the RUN position. Observe indicator lamp for glow plugs. When

cylinder temperature is great enough to sustain combustion, the indicator lamp will go

off and the engine can be started.

6. Turn key switch to START position. Release the key and allow the switch to return to

RUN position when the engine starts.

IMPORTANT: Within seconds after starting the engine, the oil pressure should

exceed 10 psi (69 kPa) minimum. If the oil pressure does not meet these minimum

limits, stop the engine, locate and correct the problem, or see your authorized

Cummins MerCruiser Diesel dealer / distributor if you are unable to determine the

problem.

7. Ensure charge indicator and oil pressure warning lamps are off.

CAUTION

Do not increase the engine speed until the oil pressure gauge indicates normal.

Shut the engine down if oil pressure does not register on the gauge within 20 to 30

seconds after start.

8. On D4.2L only: reset Cold Start Lever when engine idles smoothly.
