Safety Precautions
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.
Never use start spray or similar to start the
engine. The starter element may cause an ex-
plosion in the inlet manifold. Danger of person-
al 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 remov-
ing the cap completely. Take great care if a
cock, plug or engine coolant line must be re-
moved from a hot engine. It is difficult to anti-
cipate 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.
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!

Important
In this book and on the engine you will find the fol-
lowing special warning symbols.
WARNING! If these instructions are not fol-
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
(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. Some work (car-
rying 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,
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
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.
