Important
In this book and on the engine you will find the follow-
ing special warning symbols.

lowed there is a danger of personal injury, ex-
tensive damage to the product or serious me-
chanical 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 infor-
mation that will facilitate work or operations.
Below is a summary of the risks and safety precau-
tions 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 (switch-
es) and lock it (them) in the OFF position before
starting work. Set up a warning notice at the en-
gine control point or helm.
Generally, all servicing should be carried out
with the engine switched off. Some work (carry-
ing out certain adjustments for example) re-
quires 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, care-
less 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 en-
gine is running or has been turned off immedi-
ately prior to starting work on it. Reinstall all
protective parts removed during service opera-
tions before starting the engine.
Check that the warning or information decals on
the product are always clearly visible. Replace
decals that have been damaged or painted
over.
Never start the engine without installing the air
cleaner (ACL). The rotating compressor in the
Turbo can cause serious personal injury. For-
eign objects entering the intake ducts can also
cause mechanical damage.
Never use start spray or similar to start the en-
gine. The starter element may cause an explo-
sion in the inlet manifold. Danger of personal in-
jury.
Avoid opening the coolant filling cap when the
engine is hot. Steam or hot coolant can spray
out at the same time as the pressure which has
built up is 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 removed when the en-
gine is hot. Steam or hot coolant can stream 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 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, en-
sure that exhaust gases and crankcase ventila-
tion emissions are ventilated out of the working
area.
Always use protective goggles where there is a
danger of pieces of metal, sparks from grinding,
acid or other chemicals being thrown into your
eyes. Your eyes are very sensitive, injury can
lead to loss of sight!
