Please read and observe the information giv-
en in this operation manual. This will enable
you to avoid accidents, preserve the manu-
facturer’s warranty and maintain the engine
in peak operating condition.
Make sure that the manual will remain intact
and damage is prevented. Keep the manual
away from humidity and heat.
Do not alter the content of the manual.
The manual is an integral part of the engine.
Hand over the manual tot the new owner if
boat or engine is being sold.
For the Guarantee Conditions, see the Ve-
tus Diesel ‘Service and Warranty Manual’
(320199.06).
This engine has been built exclusively for the
application specied in the scope of sup-
ply and is to be used only for the intended
purpose. Any use exceeding that scope is
considered to be contrary to the intended
purpose. The manufacturer will not not as-
sume responsibility for any damage resulting
therefrom. The risks involved are to be borne
by the user.
Use in accordance with the intended pur-
pose also implies compliance with the con-
ditions laid down by the manufacturer for
operation, maintenance and servicing. The
engine should only be operated, maintained
and serviced by persons which are familiar
with the former and the hazards involved.
The relevant accident prevention guidelines
and other generally accepted safety and
industrial hygiene regulations must be ob-
served.
Unauthorized engine modications will in-
validate any liability claims against the man-
ufacturer for resultant damage.
Manipulations of the injection and regulating
system may also inuence the performance
of the engine, and its emissions. Adherence
to legislation on pollution cannot be guaran-
teed under such conditions.

that can lead to serious injury or death.
Warning
Indicates that a potential danger that can lead
to injury exists.
Caution

etc. concerned can result in serious damage
to or destruction of the engine. Some CAU-
TION indications also advise that a potential
danger exists that can lead to serious injury or
death.
note
Emphasises important procedures, circum-
stances etc.
Symbols
Indicates that the relevant procedure
must be carried out.

this manual in the context of safety:
Warning indications

1 Safety measures
• Do not smoke if refuelling.
• Avoid spilling fuel on hot surfaces. Spilled
fuel must be cleaned up immediately.
• Do not use petrol or diesel to clean compo-
nents but make use of good quality, non-
inammable, non-poisonous solvents that
are available from dealers.
• Always be alert to possible fuel or oil leak-
age!
If you discover a leak, take counter-meas-
ures immediately. If fuel or oil is spilled on
a hot engine, re can break out. This can
cause physical injury or damage to the
equipment.
• Do not ll the fuel tank while the engine is
running!
Only refuel with the engine stopped.
• Never put ammable materials in the vicin-
ity of the engine!
• Keep the engine and engine compartment
clean!
Remove all inammable materials such as
fuel, oil and other litter before it builds up
in the vicinity of the engine.
• Connecting (emergency) extra starting bat-
tery
Proceed as follows when an extra starting
battery is used to jump start the engine:
-First connect the positive lead
-Lastly connect the earth cable (negative
pole) to the engine block
If this cable is connected in error to the
negative pole of the engine battery, a
spark can occur. The result of this could
be that explosive gas produced by the
battery explodes.
-Once the engine is started, rst remove the
earth cable.
Preventing re and explosion
Fire risk!

1 Safety measures Prevention of injury
• The moving parts of the engine are danger-
ous. Never touch moving parts of the en-
gine while it is running, to prevent cuts and
other injuries.
• Stop the engine before carrying out main-
tenance!
• Always stop the engine before topping up
or replacing fuel, oil or coolant.
• Before carrying out inspection or mainte-
nance, the ignition key must be removed
and the main battery switch turned o.
• Satisfy yourself that everything is in order
before the engine is started again!
Make sure that no-one is working on or
close to the engine before you start it. Re-
move all foreign objects from around the
engine, such as litter, oil, tools and other
components that are not part of the engine.
• Install all protective covers!
To prevent injury, make sure that all protec-
tive covers and cover plates are replaced
over moving parts.
• Remove any tool used to turn the engine
over. If you leave this in position, serious
injury or damage to the equipment can re-
sult.
• NEVER open the cap of the expansion tank
when the engine is at working temperature.
• Only check the coolant level after the en-
gine has been stopped and the ller cap
on the heat exchanger is cool enough to be
removed with bare hands.
• Never attempt to adjust the fan belt on a
running engine.

1 Safety measures Prevention of injury
• Be careful with battery acid!
If battery acid comes in contact with the
eyes or skin, rinse the aected part imme-
diately with copious amounts of water. If
battery acid comes in contact with the eyes,
rinse them out immediately with plenty of
water and consult a doctor.
• Be careful with antifreeze!
If you accidentally swallow antifreeze, make
yourself vomit and consult a doctor imme-
diately. If antifreeze comes in contact with
your eyes, wash them out immediately with
plenty of water and consult a doctor.
• Make sure that you are wearing suitable
clothing before starting work!
For your own safety you will most likely
need special equipment – safety helmet,
eye protection, safety boots, safety gog-
gles, heavy gloves, ear protectors etc. Use
them when necessary.
• Carry out maintenance procedures safely
by only using suitable tools.
• Exhaust gases
Do not start the engine if the exhaust sys-
tem is not connected.

8
When the engine stops suddenly:
If the engine stops suddenly, do not start it
again immediately. Track down the cause and
carry out the necessary repairs before you
start the engine again. If you do not do this,
serious engine problems can develop.
If the oil pressure is too low:
Stop the engine immediately and check the
lubrication system. Running an engine with
low oil pressure can cause bearing and other
parts to seize.
lf the engine overheats:
If the engine should overheat, do not switch
it o immediately. If an overheated engine is
stopped suddenly, this can cause the coolant
temperature to rise rapidly and moving parts
to seize. First let the engine run in neutral to al-
low the hot parts of the engine to cool down,
stop the engine and allow it to cool, and then
gradually top up the coolant. Remember:
adding coolant to an overheated engine can
cause damage to the cylinder head.
If the fan belt is broken:
Immediately stop the engine. If an engine is
used with a broken fan belt, this can lead to
the engine overheating, which in turn can
cause coolant to spray out of the expansion
tank.
If the engine behaves strangely:
Stop the engine or reduce the speed as far as
possible.
Do not use the engine again until the cause of
the defect has been solved.
