Important

In this book and on the product, you will find the fol-
lowing special warning symbols.

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 in-
formation 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
(switches) and lock it (them) in the OFF posi-
tion before starting work. Set up a warning no-
tice at the engine control point or helm.

Generally, all servicing should be carried out
with the engine switched off. However, some
work, certain adjustments for example, require
that the engine is running when they are car-
ried out. Approaching a running engine is dan-
gerous. Loose clothing or long hair can catch
in rotating parts and cause serious personal
injury.
If working in proximity to a running engine,
careless movements or a dropped tool can re-
sult in personal injury. Avoid burns. Take pre-
cautions to avoid hot surfaces (exhausts, tur-
bochargers, charge air pipes and starter ele-
ments 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 or information decals
on the product are always clearly visible. Re-
place decals that have been damaged or paint-
ed over.

Engines with turbochargers: Never start the
engine without installing the air cleaner (ACL)
filter. The rotating compressor in the turbo-
charger 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. An explosion may occur in the inlet
manifold. Danger of personal injury.

Avoid opening the filler cap for the engine
coolant system (freshwater cooled engines)
when the engine is still hot. Steam or hot cool-
ant can spray out. Open the coolant filler cap
carefully and slowly to release the 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 getting hot oil
on the skin. Ensure that the lubrication system
is not under pressure before carrying out any
work. Never start or operate the engine with
the oil filler cap removed, otherwise oil could
be ejected.

Stop the engine and close the seacock valve
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 extracted from the
workshop area.
