− Run the engines idle and with no load for five minutes. During pre-
heating carry out the following checks:
• check for liquid and air leaks;
• check all devices.
Check the devices and record the data while the engines are
operating. The data comparison will help with time to determine the
standard values of each device. This will help beside to detect a
possible wrong operation. Verify possible remarkable reading
variations.
− After the engines have run with no load for five minutes and when all
checks have been performed, increase the engine speed up to 1/2 of
rated speed.
− Verify the water drain at sea water outlet. If the water drain is not
visible, or if the water flow is not hindered, carry out following
procedure:
• stop the engine immediately;
• check that the inlet filter or the sea water strainer are not clogged,
remove clogging;
• check for leaks in the cooling system and in the auxiliary water
pumps.
− Check for liquid and air leaks.
− Carry out all necessary repairs before starting the engines.
− When all checks have been performed, set the throttle lever to idle
and start the operation.
− Check for abnormal noises or excessive smoke. Otherwise stop
engines and call the customer support.
− Check that the alternators are recharging the batteries.
− Verify the efficiency of the instruments, from the plotter to the radar,
VHF, compass, etc.
S
CAUTION
To avoid overheating and possible damages to the engines, make sure
that water drain is visible from sea water outlet and/or that water flow is
not hindered. If the water flow is hindered and/or the water drain is not
visible from sea water outlet, follow the recommended procedure.

DANGER
Make sure that no crew stands in front of gas exhausts and near the
mooring ropes.
S
CAUTION
Should a “magneto-thermal switch” trip, do not try repeatedly to reset it
but check the relevant electric system condition.
S
CAUTION
We suggest avoiding slow running for periods longer than 5 minutes.
The slow run implies major wear of the engine mechanical parts and is
the most harmful of the poisonous exhausts.
