Preface
5
Dear Customer,
these Operating Instructions are intended to familiarize you with your new MAN Diesel
engine and how it operates.
This manual is supplemented by the publication “Fuels, Lubricants and Coolants for MAN
Diesel Engines” and the “Service record book”.
Note:
All three publications belong to the engine and must always be kept ready to
hand near the engine in the engine room.
Comply in full with instructions relating to operation, prevention of accidents and
environmental protection.
MAN Diesel engines are developed and manufactured in line with the latest state of the
art. However, trouble-free operation and high performance can only be achieved if the
specified maintenance intervals are observed and only approved fuels, lubricants and
coolants are used.
It is imperative and in your own interest to entrust your MAN Local Service Centre with
the removal of any disturbances and with the performance of checking, setting, and
repair work.
Yours faithfully,
MAN Nutzfahrzeuge Aktiengesellschaft
Werk Nürnberg

Important instructions which concern technical safety and protection of persons are emphasised as shown below.
Danger:
This refers to working and operating procedures which must be complied with in
order to rule out the risk to persons.
Caution:
This refers to working and operating procedures which must be complied with in
order to prevent damage to or destruction of material.
Note:
Explanations useful for understanding the working or operating procedure to be
performed.
Fitting flat seals / gaskets
Flat seals / gaskets are often inserted with sealing agents or adhesives to make fitting
them easier or to achieve better sealing. Flat seals may slip in operation due to the “sewing-machine” effect, in particular if they are used between parts with different rates of linear expansion under heat (e.g. aluminium and cast iron), and leaks may then occur.
Example:
the cap of the front crankshaft seal. If a sealing agent or an adhesive is used here the flat
seal will move inwards in the course of time as a result of the different expansion rates of
the materials. Oil will be lost, for which the shaft seal may be thought to be responsible.
Flat seals / gaskets can be fitted properly only if the following points are observed:
D Use only genuine MAN seals / gaskets
D The sealing faces must be undamaged and clean
D Do not use any sealing agent or adhesive – as an aid to fitting the seals a little grease
can be used if necessary so that the seal will stick to the part to be fitted
D Tighten bolts evenly to the specified torque

General notes
Handling diesel engines and the necessary resources is no problem when the personnel commissioned with operation and maintenance are trained accordingly
and use their common sense.
This summary is a compilation of the most important regulations. These are broken down
into main sections which contain the information necessary for preventing injury to persons, damage to property and pollution. In addition to these regulations those dictated by
the type of engine and its site are to be observed also.
Important:
If, despite all precautions, an accident occurs, in particular through contact with caustic
acids, fuel penetrating the skin, scalding from hot oil, anti-freeze being splashed in the
eyes etc., consult a doctor immediately.
1. Regulations designed to prevent accidents with injury to persons
During commissioning, starting and operation
D Before putting the engine into operation for the first time, read the oper-
ating instructions carefully and familiarize yourself with the “critical”
points. If you are unsure, ask your MAN representative.
D For reasons of safety we recommend you attach a notice to the door of
the engine room prohibiting the access of unauthorized persons and that
you draw the attention of the operating personal to the fact that they are
responsible for the safety of persons who enter the engine room.
D The engine must be started and operated only by authorized personnel.
Ensure that the engine cannot be started by unauthorized persons.
D When the engine is running, do not get too close to the rotating parts.
Wear close-fitting clothing.
D Do not touch the engine with bare hands when it is warm from operation
– risk of burns.
D Exhaust gases are toxic. Comply with the instructions for the installation
of MAN Diesel engines which are to be operated in enclosed spaces.
Ensure that there is adequate ventilation and air extraction.
D Keep vicinity of engine, ladders and stairways free of oil and grease.
Accidents caused by slipping can have serious consequences.
Safety regulations
11
During maintenance and care
D Always carry out maintenance work when the engine is switched off.
If the engine has to be maintained while it is running, e.g. changing the
elements of change-over filters, remember that there is a risk of scalding. Do not get too close to rotating parts.
D Change the oil when the engines is warm from operation.
Caution:
There is a risk of burns and scalding. Do not touch oil drain plugs or oil
filters with bare hands.
ËË
D Take into account the amount of oil in the sump. Use a vessel of suffi-
cient size to ensure that the oil will not overflow.
D Open the coolant circuit only when the engine has cooled down.
If opening while the engine is still warm is unavoidable, comply with the
instructions in the chapter entitled “Maintenance and Care”.
D Neither tighten up nor open pipes and hoses (lube oil circuit, coolant cir-
cuit and any additional hydraulic oil circuit) during the operation.
The fluids which flow out can cause injury.
D Fuel is inflammable. Do not smoke or use naked lights in its vicinity. The
tank must be filled only when the engine is switched off.
D When using compressed air, e.g. for cleaning the radiator, wear goggles.
D Keep service products (anti-freeze) only in containers which can not be
confused with drinks containers.
D Comply with the manufacturer’s instructions when handling batteries.
Caution:
Accumulator acid is toxic and caustic. Battery gases are explosive.
Safety regulations
12
2. Regulations designed to prevent damage to engine and premature wear
Do not demand more from the engine than it is able to supply in its intended application.
Detailed information on this can be found in the sales literature. The injection pump must
not be adjusted without prior written permission of MAN Nürnberg.
If faults occur, find the cause immediately and have it eliminated in order to prevent more
serious damage.
Use only genuine MAN spare parts. MAN will accept no responsibility for damage resulting from the installation of other parts which are supposedly “just as good”.
In addition to the above, note the following points:
D Never let the engine run when dry, i.e. without lube oil or coolant.
D When starting do not use any additional starting aids (e.g. injection with starting pilot).
D Use only MAN-approved service products (fuel, engine oil, anti-freeze and anti-cor-
rosion agent). Pay attention to cleanliness. The Diesel fuel must be free of water. See
“Maintenance and care”.
D Have the engine maintained at the specified intervals.
D Do not switch off the engine immediately when it is warm, but let it run without load for
about 5 minutes so that temperature equalization can take place.
D Never put cold coolant into an overheated engine. See “Maintenance and care”.
D Do not add so much engine oil that the oil level rises above the max. marking on
the dipstick. Do not exceed the maximum permissible tilt of the engine.
Serious damage to the engine may result if these instructions are not adhered to.
D Always ensure that the testing and monitoring equipment (for battery charge, oil pres-
sure, coolant temperature) function satisfactorily.
D Comply with instructions for operation of the alternator. See “Maintenance and care”.
D Do not let the raw water pump run dry. If there is a risk of frost, drain the pump when
the engine is switched off.
3. Regulations designed to prevent pollution
Engine oil and filter elements / cartridges, fuel / fuel filter
D Take old oil only to an old oil collection point.
Safety regulations
13
D Take strict precautions to ensure that no oil or Diesel fuel gets into the drains or the
ground.
Caution:
The drinking water supply could be contaminated.
D Filter elements are classed as dangerous waste and must be treated as such.
Coolant
D Treat undiluted anti-corrosion agent and / or anti-freeze as dangerous waste.
D When disposing of spent coolant comply with the regulations of the relevant local auth-
orities.
4. Notes on safety in handling used engine oil ∗
Prolonged or repeated contact between the skin and any kind of engine oil decreases the
skin. Drying, irritation or inflammation of the skin may therefore occur. Used engine oil
also contains dangerous substances which have caused skin cancer in animal experiments. If the basic rules of hygiene and health and safety at work are observed, health
risks are not to the expected as a result of handling used engine oil.
Health precautions:
D Avoid prolonged or repeated skin contact with used engine oil.
D Protect your skin by means of suitable agents (creams etc.) or wear protective gloves.
D Clean skin which has been in contact with engine oil.
– Wash thoroughly with soap and water. A nailbrush is an effective aid.
– Certain products make it easier to clean your hands.
– Do not use petrol, Diesel fuel, gas oil, thinners or solvents as washing agents.
D After washing apply a fatty skin cream to the skin.
D Change oil-soaked clothing and shoes.
D Do not put oily rags into your pockets.
Ensure that used engine oil is disposed of properly
– Engine oil can endanger the water supply –
For this reason do not let engine oil get into the ground, waterways, the drains or the
sewers. Violations are punishable.
Collect and dispose of used engine oil carefully. For information on collection points
please contact the seller, the supplier or the local authorities.

First commissioning
When putting a new or overhauled engine into operation for the first time pay attention to
the “Installation instructions for MAN marine diesel engines” without fail.
It is recommended that new or overhauled engines should not be operated at a load
higher than about 75% maximum load during the first few hours of operation. Initial run-in
should be at varying speeds. After this initial run-in, the engine should be brought up to
full output gradually.
Note:
Use only approved fuels, lubricants etc. (see brochure “Fuels, lubricants etc.”).
Otherwise the manufacturer’s warranty will become null and void.
Filling with fuel
Caution:
Fill the tank only when the engine is switched off. Pay attention to cleanliness.
Do not spill fuel.
Use only approved fuels (see “Fuels, Lubricants etc.”).
Filling-in of coolant
Fill the cooling system of the engine with a mixture of drinkable tap water and anti-freeze
agent on ethylene glycole basis or anti-corrosion agent.
See Publication “Fuels, Lubricants and Coolants for MAN Diesel Engines”.
D Pour in coolant slowly via expansion tank, see page 57
D For coolant filling quantity, see “Technical data”
Commissioning and operation
17
Raw water pump
Do not let raw water pump run dry.
Make sure that all valves / cocks in the
raw water circuit are open.
If there is a risk of frost, drain the raw water pump.
Filling with engine oil
Caution:
Do not add so much engine oil
that the oil level rises above the
max. marking on the dipstick.
Overfilling will result in damage to
the engine.
The engines are as a rule supplied without oil.
Pour oil into engine via filler neck (arrow),
see page 51.
For the quantity required see “Technical
Data”.
Commissioning and operation
18
Commissioning
Before daily starting the engine, check fuel level, coolant level and engine oil level and
replenish, if necessary.
Note:
Use only approved fuels, lubricants etc. (see brochure “Fuels, lubricants etc.”).
Otherwise the manufacturer’s warranty will become null and void.
Checking oil level
Check engine oil level only approx.
20 minutes after the unit has been
switched off.
D Pull out dipstick (arrow)
D wipe it with a clean, lintfree cloth
D and push it in again up to the stop
D Pull out dipstick again
The oil level should be between the two
notches in the dipstick and must never fall
below the lower notch. Top up oil as necessary.
Caution:
Do not add so much engine oil
that the oil level rises above the
max. marking on the dipstick.
Overfilling will result in damage to
the engine.
Ensure outmost cleanliness when handling fuels, lubricants and coolants.

Starting
Danger:
Before starting make sure that no-one is in the engine’s danger area.
Caution:
When starting do not use any additional starting aids (e.g. injection with starting
pilot).
Ensure that the gearbox is in neutral.
Insert starter key and turn it to position “I”. The check lamp comes on to show that the
engine is ready for operation.
Turn starter key further to position “II” (pre-glow). The display lamp (usually in the driver’s
station) comes on.
After the pre-glow period the display lamp begins to flash. This signalizes that the engine
is ready for starting.
Note:
If the engine is not equipped with a pre-glowing function, immediately turn the
starter key through to position “III”.
Turn key further up to the stop (position “III”). The display lamp goes out. The starter motor is actuated.
Lube oil pressure must build up at the oil pressure gauge. If it does not, switch off the engine immediately.
Do not operate starter for longer than 10 seconds at a time.
After ignition of the engine, release the starter button and adjust control lever for desired
speed.
If engine fails to start, release the key, wait about 30 seconds, then operate starter again.
For repeated starting turn the key back to OFF.
If the engine is kept idling for long periods it may cool down and thus start to emit white
or blue smoke.
We therefore recommend that you do not let the engine idle for more than 5 minutes.
It is well known that with any internal combustion engine wear is higher during idling.
Idling for longer periods is also an environmental nuisance.

The device distinguishes between the following types of alarm, error messages:
D Preliminary alarm: the corresponding light-emitting diode flashes
D Main alarm: the corresponding light-emitting diode flashes
light-emitting diode “Alarm” flashes
In the case of an engine slow down alarm,
“Engine slow down” also flashes
In the case of a stop alarm, “Engine stop” also flashes
D Sensor fault: the corresponding light-emitting diode flashes
light-emitting diode “Sensor fault” flashes
The alarm “Sensor fault” means that the corresponding sensor is classified by the monitoring system as defective, as it is returning an unrealistic value.
The engine speed is not reduced.
In the event of a fault in the electronic system, the warning lamp lights up continuously.
There is then a defect in the electronic fuel injection (EDC).
So as not to endanger the engine, the engine power is automatically reduced in the case
of selected main alarms.
Note for engines with electronically controlled diesel injection (EDC):
After the ignition has been switched on, the lamp “Electronic fault” lights up briefly
(lamp test). If there is a fault in the electronically controlled diesel injection (EDC),
the lamp “Electronic fault” lights up permanently.
