Important

In this book and on the engine you will find the
following special warning symbols.
WARNING! If these instructions are not
followed there is a danger of personal injury,
extensive damage to the product or serious
mechanical malfunction.
IMPORTANT! Used to draw your attention to
something that can cause damage, product
malfunction or damage to property.
NOTE! Used to draw your attention to important
information that will facilitate work or operations.
Below is a summary of the risks 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) in the OFF position before
starting work. Set up a warning notice at the
engine control point or helm.
Generally, all servicing should be carried out
with the engine switched off. Some work
(carrying out certain adjustments for example)
requires the engine to be running. Approaching
a running engine is dangerous. Loose clothing
or long hair can fasten in rotating parts and
cause serious personal injury.
If working in proximity to a running engine,
careless movements or a dropped tool can
result in personal injury. Avoid burns. Take
precautions to avoid hot surfaces (exhausts,
turbochargers, charge air pipes and starter
elements, etc.) and liquids in supply lines and
hoses when the engine is running or has been
turned off immediately prior to starting work on
it. Reinstall all protective parts removed during
service operations before starting the engine.
Check that the warning information decals on
the product are always clearly visible.
Replace decals that have been damaged or
painted over.
Engine with turbocharger: Never start the en-
gine without installing the air cleaner (ACL).
The rotating compressor in the Turbo can
cause serious personal injury. Foreign
objects entering the intake ducts can also
cause mechanical damage.
Never use start spray or similar to start the
engine. The starter element may cause an
explosion in the inlet manifold. Danger of
personal injury.
Avoid opening the filler cap for engine
coolant system (freshwater cooled engines)
when the engine is still hot. Steam or hot
coolant can spray out. Open the coolant filler
cap carefully and slowly to release pressure
before removing the cap completely. Take
great care if a cock, plug or engine coolant
line must be removed from a hot engine. It is
difficult to anticipate in which direction steam
or hot coolant can spray out.
Hot oil can cause burns. Avoid skin contact
with hot oil. Ensure that the lubrication
system is not under pressure before
commencing work on it. Never start or
operate the engine with the oil filler cap
removed, otherwise oil could be ejected.
Stop the engine and close the sea cock
before carrying out operations on the engine
cooling system.
Only start the engine in a well-ventilated
area. If operating the engine in an enclosed
space, ensure that exhaust gases and
crankcase ventilation emissions are
ventilated out of the working area.
