Below is a summary of the risks involved and safety
precautions you should always observe or carry out
when operating or servicing the engine.
Immobilize the engine by turning off the power
supply to the engine at the main switch (es) and
lock it (them) turned off before starting work. Set
up a warning notice by the helm station.
As a general rule all service operations must be
carried out with the engine stopped. Some work,
such as adjustments, need the engine to be run-
ning, however. Approaching an engine which is
running is a safety risk. Remember that loose
clothing or long hair can fasten in rotating parts
and cause serious personal injury.
If work is done adjacent to a running engine, a
careless movement or a dropped tool can lead,
in the worst case, to personal injury. Be careful
with hot surfaces (exhaust pipes, turbos, charge
air pipes, starting heaters etc.) and hot fluids in
pipes and hoses on an engine which is running
or which has just stopped. Always refit shields
that have been removed for service work before
starting the engine.
Check that the warning or information labels on
the product are always clearly visible. Replace
labels which have been damaged or painted over.
Never start the engine without installing the air
cleaner filter. The rotating compressor turbine in
the turbocharger can cause severe injury. For-
eign objects entering the intake ducts can also
cause mechanical damage.
Never use start spray or similar products as a
starting aid. They may cause an explosion in
the inlet manifold. Danger of personal injury.
Avoid opening the coolant filling cap when the en-
gine is hot. Steam or hot coolant can spray out
and the system pressure will be lost. Open the
filler cap slowly, and release the pressure in the
cooling system if the filling cap or tap has to be
opened, or if a plug or coolant hose has to be re-
moved when the engine is hot. Steam or hot cool-
ant might spray out in an unexpected direction.
Hot oil can cause burns. Avoid skin contact with
hot oil. Ensure that the lubrication system is not
under pressure before carrying out any work.
Never start or operate the engine with the oil fill-
er cap removed, otherwise oil could be ejected.
Stop the engine and close the sea cocks before
doing any work on the cooling system.
Only start the engine in a well- ventilated area.
When operated in a confined space, exhaust
fumes and crankcase gases must be ventilated
from the engine bay or workshop area.
Always use protective glasses or goggles when
carrying out work where there is a risk of splin-
ters, grinding sparks, acid splashes or where
other chemicals are used. Your eyes are ex-
tremely sensitive, injury could cause blindness!
