Dear Customer,
these Operating Instructions are intended to familiarize you with your new MAN Diesel
engine and how it operates.
The Publication “Fuels, Lubricants and Coolants for MAN Diesel Engines” supplements
these Operating Instructions.
Note:
Both publications apply to the engine and must always be kept to hand in its vi-
cinity in the engine room.
Please read this Manual and the “Instructions for the installation of MAN Diesel Engines”
before you put the new engine into operation.
Comply in full with instructions relating to operation, prevention of accidents and envi-
ronmental 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

Instructions
6
Important instructions which concern technical safety and protection of persons are em-
phasised 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 “sew-
ing-machine” effect, in particular if they are used between parts with different rates of lin-
ear 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 ob-
served:
DUse only genuine MAN seals / gaskets
DThe sealing faces must be undamaged and clean
DDo 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
DTighten bolts evenly to the specified torque

General notes
Handling diesel engines and the necessary resources is no problem when the per-
sonnel 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 per-
sons, 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
DBefore 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.
DFor 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.
DThe engine must be started and operated only by authorized personnel.
Ensure that the engine cannot be started by unauthorized persons.
DWhen the engine is running, do not get too close to the rotating parts.
Wear close-fitting clothing.
DDo not touch the engine with bare hands when it is warm from operation
−risk of burns.
ËË
DExhaust 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.
DKeep 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
DAlways 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 scald-
ing. Do not get too close to rotating parts.
DChange 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
ËË
DTake into account the amount of oil in the sump. Use a vessel of suffi-
cient size to ensure that the oil will not overflow.
DOpen 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”.
ËË
DNeither 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.
DFuel is inflammable. Do not smoke or use naked lights in its vicinity. The
tank must be filled only when the engine is switched off.
DWhen using compressed air, e.g. for cleaning the radiator, wear goggles.
DKeep service products (anti-freeze) only in containers which can not be
confused with drinks containers.
DComply 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 result-
ing from the installation of other parts which are supposedly “just as good”.
In addition to the above, note the following points:
DNever let the engine run when dry, i.e. without lube oil or coolant.
DWhen starting do not use any additional starting aids (e.g. injection with starting pilot).
DUse 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”.
DHave the engine maintained at the specified intervals.
DDo 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.
DNever put cold coolant into an overheated engine. See “Maintenance and care”.
DDo 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.
DAlways ensure that the testing and monitoring equipment (for battery charge, oil pres-
sure, coolant temperature) function satisfactorily.
DComply with instructions for operation of the alternator. See “Maintenance and care”.
3. Regulations designed to prevent pollution
Engine oil and filter elements / cartridges, fuel / fuel filter
DTake old oil only to an old oil collection point.

Safety regulations
13
DTake 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.
DFilter elements are classed as dangerous waste and must be treated as such.
Coolant
DTreat undiluted anti-corrosion agent and / or anti-freeze as dangerous waste.
DWhen 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 experi-
ments. 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:
DAvoid prolonged or repeated skin contact with used engine oil.
DProtect your skin by means of suitable agents (creams etc.) or wear protective gloves.
DClean 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.
DAfter washing apply a fatty skin cream to the skin.
DChange oil-soaked clothing and shoes.
DDo 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.

Commissioning and operation
14
First commissioning
At the time of initial commissioning of a new or overhauled engine make sure to have ob-
served the “Technical Information for the installation of MAN Diesel engines”.
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 brochure “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 the ethylene glycole basis or anti-corrosion agent.
See Publication “Fuels, Lubricants and Coolants for MAN Diesel Engines”.
DObserve / adhere to vehicle manufacturer’s filling specifications
DSlowly pour in coolant (max. 10 ltr./min)
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, see page 19.
For the quantity required see “Technical Data”.
Note:
Before putting the hydraulic pump into operation for the first time fill it with oil.
Heed the manufacturer’s instructions!

Operation monitoring system
Caution:
Do not overload the engine. Do not exceed the maximum permissible tilt of the
engine. If faults occur, find their cause immediately and have them eliminated in
order to prevent more serious damage!
Monitor the oil pressure of the engine lubrication and coolant agent temperature during
operations.
If the monitoring devices register a drop in the lube oil pressure, switch off the engine im-
mediately.
Shutting down
Set engine to idle speed.
After engine has been under a heavy load let it run idle for approx. 5 minutes.
Turn off engine via EDC.
Danger:
Ensure that the engine cannot be started by unauthorized persons.

18
Lubrication system
Ensure utmost cleanliness when handling fuels, lubricants and coolants.
Note:
Use only approved fuels, lubricants etc. (see brochure “Fuels, lubricants etc.”).
Otherwise the manufacturer’s warranty will become null and void.
Refilling with oil
Danger:
The oil is hot- risk of scalding. Do
not touch the oil drain plug with
bare fingers. Oil is an environ-
mental hazard. Handle it with
care!
With the engine at operating temperature,
remove the oil drain plugs on the oil sump
and the oil filter bowl and allow the old oil
to drain off completely.
Use a vessel of sufficient size to ensure
that the oil does not overflow.
As the oil drain plug is often not access-
ible, a manually operated vane pump may
be attached to the engine for draining the
oil.
Pump the old oil out of the sump while the
engine is still warm. Remove oil drain
plugs in oil filter bowl and let old oil drain
out of oil filters.
Caution:
Used oil is dangerous waste.
Observe safety regulations to pre-
vent damage to the environment.
Refit the oil drain plugs with new gaskets.

neck À.
After filling start the engine and let it run
for a few minutes at low speed.
Caution:
If no oil pressure builds up after
approx. 10 seconds switch off the
engine immediately.
Check oil pressure and check that there is
no oil leakage.
Then shut down the engine. After about
20 minutes, check the oil level.
