Hot surfaces and fluids
At operating temperature, the engine and its com-
ponents are hot. A hot engine always involves risk
for burn injuries. Take care with hot surfaces. E.g.:
exhaust manifold, turbocharger, oil pan, charge air
pipe, starting heater, hot coolant and warm lubricant
in pipes and hoses.
Warning!
Do not open the crankcase co-
vers while the engine is still hot.
Carbon monoxide poisoning
Start the engine in well-ventilated spaces only. When
running in confined spaces, the exhaust gases and
crankcase gases must be evacuated.
Chemicals
Most chemicals such as glycol, anti-corrosion agent,
preservatives, degreasing agent, etc., are hazardous
to health. Always read and follow the directions on
the packaging.
Certain chemicals such as preservatives are flam-
mable and harmful to inhale. Provide good ventilation
and use breathing protection when spraying. Always
read and follow the directions on the packaging. Sto-
re chemicals and other hazardous materials out of
reach of children. Leave left over or used chemicals
to a destruction plant.
Cooling system
There is a risk of water entering when working on
the seawater system. Therefore, stop the engine and
close the seawater cock before starting work.
Avoid opening the coolant filler cap when the engine
is warm. Steam or hot coolant may spurt out and
cause burn injuries.
If the filler cap, coolant pipe, cock, etc., must ne-
vertheless be opened or dismantled while the engine
is warm, the filler cap must be opened carefully to
release the pressure before removing it completely
and starting work. Note that the coolant can still be
hot and cause burn injuries.
Lubricating system
Hot oil can cause burn injuries. Avoid skin contact
with warm oil. Make sure the lubricating system is
depressurized before starting work. Never start or run
the engine with the oil filler cap removed or there will
be a risk of the oil being thrown out.
Fuel system
Always protect your hands when carrying out leak
detection.
Escaping fluids under pressure can pierce bodily tis-
sue and cause serious injury. Risk of blood poisoning.
Always cover any electric component if it is located
under the fuel filter. Otherwise it might be damaged
by fuel spills.
