Safety, Accident Prevention and Environmental Protection Instructions
These instructions must be read and followed by every person involved inoperation, maintenance or transportation of the machinery plant.
General
In addition to the instructions in this publication, the applicable country-specific legislation and other compulsoryregulations regarding accident prevention must be observed.
This engine is a state-of-the-art product and conforms with all applicable specifications and regulations. Neverthe-less, persons and property may be at risk in the event of
• Incorrect use• Operation, maintenance and repair by unqualified personnel• Modifications or conversions• Non-compliance with the Safety Instructions
Correct Use
The engine is intended exclusively for the application specified in the contract or upon delivery. Any other use isconsidered improper use. The manufacturer will accept no liability for any resultant damage. The responsibility isborne by the user alone.
Correct use also includes observation of and compliance with the maintenance specifications.
Personnel Requirements
Work on the engine must only be carried out by properly qualified personnel.
The specified legal minimum age must be respected.
Responsibilities of the operating, maintenance and repair personnel must be specified.
Modifications or Conversions
Modifications made by the customer to the engine may affect safety.
MTU will accept no liability or warranty claims for any damage caused by unauthorised modifications or conver-sions.
Organisational Measures
This publication must be issued to all personnel involved in operation, maintenance, repair or transportation.
It must be kept at hand near the engine and accessible to all personnel involved in operation, maintenance, repairor transportation.
The personnel must be instructed on engine operation and repair by means of this publication, and in particular thesafety instructions must be explained.
This is especially important for personnel who work on the engine only on an occasional basis. Such personnelmust be given instructions repeatedly.
Spare Parts
Only genuine MTU spare parts must be used to replace components or assemblies. In event of any damagedcaused by the use of other spare parts, no liability or warranty claims vis–à–vis the engine manufacturer will be ac-cepted.
Working Clothes and Protective Equipment
Wear proper work clothing for all work.
![Page 8: DT_MUE_00057_US_1](https://reader031.vdocuments.us/reader031/viewer/2022020207/552665a3550346ad6e8b4ccd/html5/thumbnails/8.jpg)
Section ! Safety InstructionsPage 2
15340/20 E 00–01
Depending on the kind of work, use additional protective equipment, e.g. protective goggles, protective gloves, pro-tective helmet, apron.
Work clothing must be tight-fitting so that it does not catch on rotating or projecting components.
Do not wear jewellery (e.g. rings, chains, etc.).
Transportation
Lift the engine only with the lifting eyes provided.
Use only the transport and lifting equipment approved by MTU.
Take note of the engine centre of gravity.
The engine must only be transported in installation position.
In the case of special packaging with aluminium foil, suspend the engine on the lifting eyes of the bearing pedestalor transport with equipment suitable for heavy loads (forklift truck).
Prior to transporting the engine, it is imperative to install transportation locking devices for crankshaft and enginemounts.
Secure the engine against tilting during transportation. The engine must be especially secured against slipping ortilting when going up inclines and ramps.
Setting the Engine Down after Transportation
Place the engine only on an even, firm surface.
Ensure appropriate consistency and load-bearing capacity of the ground or support surface.
Never place an engine on the oil pan unless expressly authorised by MTU on a case-by-case basis to do so.
Working with Laser Equipment
When working with laser equipment, always wear special laser-protection goggles.
Laser equipment can generate extremely intensive, concentrated radiation by the effect of stimulated emission inthe range of visible light or in the infrared or ultraviolet spectral range. The photochemical, thermal and optome-chanical effects of the laser can cause damage. The main danger is irreparable damage to the eyes.
Laser equipment must be fitted with the protective devices necessary for safe operation according to type and ap-plication.
For conducting ray procedures and measurement work, only the following laser devices must be used:
• Laser devices of classes 1, 2 or 3A,
• Laser devices of class 3B, which have maximum output only in the visible wavelength range (400 to 700 nm), amaximum output of 5 mW, and in which the beam axis and surface are designed to prevent any risk to the eyes.
Engine Operation
When the engine is running, always wear ear protectors.
Ensure that the engine room is well ventilated.
Mop up any leaked or spilt fluids and lubricants immediately or soak up with a suitable bonding agent.
Exhaust gases from combustion engines are poisonous. Inhalation of poisonous exhaust gases is a health hazard.The exhaust pipework must be leak-free and must discharge the gases to atmosphere.
During engine operation, do not touch battery terminals, generator terminals or cables.
Inadequate protection of electrical components can lead to electric shocks and serious injuries.
When the engine is running, never release coolant, oil, fuel, compressed air or hydraulic lines.

Section !Safety InstructionsPage 3
15340/20 E 00–01
Maintenance and Repair
Compliance with maintenance and repair specifications is an important safety factor.
Unless expressly permitted, no maintenance or repair work must be carried out with the engine running. The en-gine must be secured against inadvertent starting and the battery disconnected. Attach sign “Do not operate” inoperating area or to control equipment. Persons not involved must keep clear.
Never attempt to rectify faults or carry out repairs if you do not have the necessary experience or special tools re-quired. Maintenance and repair work must only be carried out by authorised, qualified personnel.
Use only the proper, calibrated tools.
Do not work on engines or components which are only held by lifting equipment or crane. Always support thesecomponents in accordance with regulations on suitable frames or stands before beginning any maintenance or re-pair work.
Before barring the engine, make sure that nobody is standing in the danger zone. After working on the engine,check that all guards have been reinstalled and that all tools and loose components have been removed from theengine.
Fluids emerging under high pressure can penetrate clothing and skin and may cause serious injury. Before startingwork, relieve pressure in systems and H.P. lines which are to be opened.
Never bend a fuel line and do not install bent lines. Keep fuel injection lines and connections clean. Always sealconnections with caps or covers if a line is removed or opened.
During maintenance and repair work, take care not to damage the fuel lines. To tighten connections when installinglines, use the correct tightening torque and ensure that all retainers and dampers are installed correctly.
Ensure that all fuel injection lines and compressed oil lines have sufficient play to avoid contact with other compo-nents. Do not place fuel or oil lines near hot components, except when necessary for design reasons during in-stallation.
Take care with hot fluids in lines, pipes and chambers ⇒ Risk of injury!
Not cooling period for components which are heated for installation or removal ⇒ Risk of injury!
Take special care when removing ventilation or plugs from engine. In order to avoid the discharge of highly pressur-ised liquids, hold a cloth over the screw or plug. It is even more dangerous if the engine has recently been shutdown, as the liquids can still be hot.
Take special care when draining hot fluids ⇒ Risk of injury!
When draining, collect fluids in a suitable container, mop up any spilt fluids or wipe or soak them up with a suitablebonding agent.
When changing engine oil or working on the fuel system, ensure that the engine room is adequately ventilated.
When working high on the engine, always use suitable ladders and work platforms. Make sure components areplaced on stable surfaces.
In order to prevent back injuries when lifting heavy components, adults should not lift weights between max. 10 kgand 30 kg, depending on age and sex.
• Use lifting gear or seek assistance.
• Ensure that all chains, hooks, slings, etc. are tested and authorised, are sufficiently strong and that hooks arecorrectly positioned. Lifting eyes must not be unevenly loaded.
Welding Operations
Never carry out welding work on the engine or engine-mounted units.
Never use the engine as an earth connection. – (This prevents the welding current passing through the engine andcausing scorching or burning at bearings, sliding surfaces and tooth flanks, which can lead to pitting or other ma-terial damage).
![Page 10: DT_MUE_00057_US_1](https://reader031.vdocuments.us/reader031/viewer/2022020207/552665a3550346ad6e8b4ccd/html5/thumbnails/10.jpg)
Section ! Safety InstructionsPage 4
15340/20 E 00–01
Never position the welding power supply cable adjacent to, or crossing MTU plant wiring harnesses. (The weldingcurrent can be induced in the wiring harnesses, which could damage the electrical unit.)
The welding unit earth connection must not be more than 60 cm from the weld point.
If components (e.g. exhaust manifold) are to be welded, they must first be removed from the engine.
When carrying out work on MTU electronics components, it is not necessary to remove connectors provided thatthe master switch for power supply has been moved from “ON” to “OFF” and the cable is disconnected from thebattery negative and positive terminals.
Hydraulic Installation and Removal
Only the hydraulic installation and removal equipment specified in the work schedule and in the assembly instruc-tions must be used.
The max. permissible push-on pressure specified for the equipment must not be exceeded.
The H.P. lines for hydraulic installation and removal are tested with 3800 bar.
Do not attempt to bend or apply force to lines.
Before starting work, pay attention to the following:
• Vent the hydraulic installation/removal tool, the pumps and the lines at the relevant points for the system to beused (e.g. open vent plugs, pump until bubble-free air emerges, close vent plugs).
• For hydraulic installation, screw on the tool with piston retracted.
• For hydraulic removal, screw on the tool with piston extended.
For a hydraulic installation/removal tool with central expansion pressure supply, screw spindle into shaft end untilcorrect sealing is achieved.
During hydraulic installation and removal, ensure that nobody is standing in the immediate vicinity of the compo-nent to be installed/removed. As long as the system is under pressure, there is the risk that the component to beinstalled/removed may be suddenly released from the pressure connection.
Before use, the tools must be checked at regular intervals (crack test).
Working on Electrical Assemblies
Switch off all live appliances before carrying out any work on electrical assemblies.
Gases released from the battery are explosive. Avoid sparks and naked flames. Do not allow battery acids to comeinto contact with skin or clothing. Wear protective goggles. Do not place tools on the battery. Before connecting thecable to the battery, check battery polarity. Battery pole reversal may lead to injury through the sudden discharge ofacid or bursting of the battery body.
Do not damage wiring during removal work and when reinstalling wiring and ensure that during operation it is notdamaged by contact with sharp objects, by rubbing against another component or by a hot surface.
Do not secure wiring to fluid-carrying lines.
On completion of the maintenance and repair work, any cables which have become loose must be correctly con-nected and secured.
Always tighten connectors with a connector pliers.
If wires are installed beside mechanical components and there is a risk of chafing, use cable clamps to properlysupport the wires.
For this purpose, no cable straps must be used as, during maintenance and/or repair work, the straps can be re-moved but not installed a second time.

Operation of Electrical Equipment
When operating electrical equipment, certain components of this equipment are live.
Noncompliance with the warning instructions given for this equipment may result in serious injury or damage toproperty.
Fire Prevention
Rectify any fuel or oil leaks immediately; even splashes of oil or fuel on hot components can cause fires – thereforealways keep the engine in a clean condition. Do not leave cloths soaked with fluids and lubricants lying around onthe engine. Do not store combustible fluids near the engine.
Do not weld pipes and components carrying oil or fuel. Before welding, clean with a nonflammable fluid.
When starting the engine with a foreign power source, connect the ground lead last and remove it first. To avoidsparks in the vicinity of the battery, connect the ground lead from the foreign power source to the ground lead of theengine or to the ground terminal of the starter.
Always keep suitable fire-fighting equipment (fire extinguishers) at hand and familiarise yourself with their use.
Noise
Noise can lead to an increased risk of accident if acoustic signals, warning shouts or noises indicating danger aredrowned.
At all workplaces with a sound pressure level over 85 dB(A), always wear ear protectors (protective wadding, plugsor capsules).
Environmental Protection
Dispose of used fluids and lubricants and filter in accordance with local regulations.
Manipulation of the injection or control system can influence the engine performance and exhaust emissions. As aresult, compliance with environmental regulations may no longer be guaranteed.
Only fuels of the specified quality required to achieve emission limits must be used.
In Germany, the VAwS (=regulations governing the use of materials that may affect water quality) is applicable,which means work must only be carried out by authorised specialist companies. (MTU is such a company.)
Auxiliary Materials
Use only fluids and lubricants that have been tested and approved by MTU.
Fluids and lubricants must be kept in suitable, properly designated containers. When using fluids, lubricants andother chemical substances, follow the safety instructions applicable to the product. Take care when handling hot,chilled or caustic materials. When using inflammable materials, avoid all sparks and do not smoke.
⇒ Lead
When working with lead or lead-containing pastes, avoid direct contact to the skin and do not inhale lead vapours.
Adopt suitable measures to avoid the formation of lead dust!
Switch on fume extraction system.
After coming into contact with lead or lead-containing materials, wash hands!
⇒ Acids and Alkaline Solutions
When working with acids and alkalis, wear protective goggles or face mask, gloves and protective clothing.
Immediately remove clothing wetted by acids and alkalis!
Rinse injuries with plenty of clean water!
Rinse eyes immediately with eyedrops or clean tap water.

Section ! Safety InstructionsPage 6
15340/20 E 00–01
⇒ Painting
When painting in other than spray booths equipped with extractors, ensure good ventilation. Make sure that adjac-ent work areas are not affected.
It is absolutely essential to wear masks providing protection against paint and solvent fumes.
Observe fire prevention regulations!
No smoking.
No naked flame!
⇒ Liquid Oxygen
Liquid oxygen is highly inflammable.
Liquid oxygen should only be stored in small quantities and in regulation containers (without fixed seals)! Do notbring liquid oxygen into contact with the body (hands), as this causes frostbite and possibly the loss of tissue.
No smoking, no naked flame (risk of explosion)! Excessive oxygen in the air leads to explosive combustion.
Do not store combustible substances (e.g. oils and greases) within 5 m of the working area!
Under no circumstances should clothing be oily or greasy.
Do not allow vapours to penetrate clothing! Oxygen enrichment in fabric can cause working clothes to ignitesuddenly!
After working with liquid oxygen, do not smoke until clothing is free of vapours!
Take great care to avoid impact and shock when working with liquid oxygen!
⇒ Liquid Nitrogen
Store liquid nitrogen only in small quantities and always in regulation containers without fixed covers.
Do not bring liquid nitrogen into contact with the body (eyes, hands) as this causes frostbite and numbing.
Wear protective clothing (including gloves and closed shoes) and protective goggles!
– Ensure the room is well ventilated (88% contamination of breathing with nitrogen will result in suffocation).
Avoid all knocks and jars to the containers, fixtures or workpieces.
⇒ Compressed Air
Compressed air is air which has been compressed at excess pressure and is stored in tanks from which it can thenbe extracted.
The pressure at which the air is kept can be read off at pressure gauges which must be connected to the com-pressed air tanks and the compressed air lines.
When working with compressed air, safety precautions must be constantly observed:• Pay special attention to the pressure level in the compressed air network and pressure vessel!• Connecting devices and equipment must either be designed for this pressure or, if the permitted pressure for the
connecting elements is lower than the pressure required, a pressure reducing valve and safety valve (set to per-mitted pressure) must form an intermediate connection. Hose coupling and connections must be securely at-tached!
• Always wear protective goggles when blowing off tools or extracting chips!• The snout of the air nozzle is provided with a protective disc (e.g. rubber disc), which prevents air-borne par-
ticles being reflected and thereby prevents injury to eyes.• First shut off compressed air lines before compressed air equipment is disconnected from the supply line or be-
fore equipment or tool is to be replaced!• Unauthorised use of compressed air, e.g. forcing flammable liquids (danger class AI, AII and B) out of con-
tainers, results in a “Risk of explosion”!• Forcing compressed air into thin-walled containers (e.g. containers made of tin, plastic and glass) for drying pur-
poses or to check for leaks results in a “Risk of explosion”!

Section !Safety InstructionsPage 7
15340/20 E 00–01
• Do not blow dirty clothing with compressed air when being worn on the body.Even compressed air at low pressure penetrates clothing and, if the jet is directed at the back, the air can enterthe anal cavity and fatally rupture the intestines!
⇒ Used Oil
Used oil may contain health-threatening combustion residues.
Rub barrier cream into hands!
Wash hands after contact with used oil.
Warning Signs
Before putting the engine into service and before working on the engine, read and follow all warning signs. Do notpaint over warning signs. Replace illegible signs.

15340/20 E 00–01
C000.000.01 Operating Instructions – PrefaceLow operating and maintenance costs as well as operational reliability and availability depend on maintenance andservicing being carried out in compliance with our specifications and instructions.It is essential that:– Trained personnel must be employed– Suitable tools be used– Original spare parts and fluids and lubricants as per MTU Fluids and Lubricants Specifications be used and– The maintenance tasks be carried out as per the MTU Maintenance Schedule.Our Product Support service is available at all times should assistance be needed.Prior to engine start-up it must be determined whether start-up is:
– after a short, scheduled operational shutdown,– after an extended out-of-service period,– initial start-up of a new engine.Accordingly, the Before-Operation Services are sub-divided into:– B1– Before-Operation Services after a short, scheduled operational shutdown– B2– Before-Operation Services after an extended operational shutdown (exceeding 1 week)– B3- Before-Operation Services before initial start-up of a new or preserved engine.Correct engine installation and alignment according to MTU regulations are basic requirements for initial enginestart-up.Prior to engine shutdown it must be determined whether:– a short, scheduled operational shutdown, or
– an extended out-of-service period is involved.In the event of an engine malfunction a decision must be made as to whether– the engine is to be shut down, or– operation may be continued, for a short period, using emergency measures, until rectification can be effected.
Note:
The code numbers on the following pages refer to the section numbers in Section G in which the checks and tasks are described.
These Operating Instructions may include components which are not installed on your engine; these may be disregarded.

15340/20 E 00–01
D000.000.01 Maintenance Schedule – PrefaceLow operating and maintenance costs as well as operational reliability and availability depend on maintenance andservicing being carried out in compliance with our specifications and instructions.The overall system, of which the engine is an integral part, must be maintained in such a way as to ensure trouble-free engine operation at all times.For this purpose, always:– Ensure that sufficient fuel is available– Ensure that the combustion air is dry and clean– Use only clean, filtered raw waterPreventive maintenance instructions– Special care should be taken to keep the machinery plant in a clean and serviceable condition at all times to facilitate
detection of possible leaks and prevent subsequent damage.– Protect rubber and synthetic parts from oil and fuel, never treat with organic detergents. Wipe with a dry cloth only.– Always replace all seals and gaskets.
D000.000.03 Maintenance SystemThe MTU maintenance concept is a preventive maintenance concept and features the W1 to W6 MaintenanceEchelons as outlined below.Preventive maintenance permits advance operational planning and increases availability.Main features of maintenance echelon
W1: Operational checks.
W2, W3 and W4: Periodic maintenance services to be carried out during out-of-service periods without the need for engine disassem-bly.
W5 –
W6: Major overhaul. This echelon requires complete engine disassembly.
The time intervals according to which W2 to W6 maintenance operations are to be performed and the relevant in-spection and maintenance tasks are based on operational experience. They have been determined so as to ensurecorrect engine operation until the next scheduled maintenance echelon. Particular operating conditions may requirethe Maintenance Schedule to be altered to compensate.NOTE:
The code numbers on the following pages refer to the group numbers in Section G.
This Maintenance Schedule may include components which are not installed on your engine; these may be disregarded.

Troubleshooting
15340/20 E 00–01
E000.000.01 General
In Event of Internal Coolant Leakage
Subsequent damage caused by corrosion must be avoided. If the engine cannot be repaired immediately, carry outthe following operations:– Drain coolant and engine oil– Introduce corrosion-inhibitor oil, kerosene or diesel fuel into the crankcase via the oil filler neck until the max. level
is reached– Remove the charge air/coolant manifolds– Remove the fuel injectors– Bar the engine manually and spray corrosion-inhibitor oil, kerosene or diesel fuel into the combustion chambers via
the opening inlet valvesIt is essential to change the engine oil after 50 operating hours as the new oil may be contaminated by coolant resi-dues left in the crankcase.NOTE:
These corrosion-prevention measures are only effective for a few days. Repair of the engine and thorough cleaning of all compon entsshould, therefore, be carried out as soon as possible.
Before restarting the repaired engine, fill with new oil and coolant in compliance with the MTU Fluids and LubricantsSpecification.
Engine Oil Diluted by Fuel
It is essential to change the engine oil before restarting the engine after rectifying the fault. Remove the old oil fromthe crankcase with particular care. Replace engine oil filter.
After Work on Engine
If running gear components, e.g. pistons, piston rings, cylinder liners, etc. have been replaced, carry out the enginerunning-in procedure.

Safety measures when carrying out welding operations on machine plants with MTU engines.
Never use the engine as an earth connection. (This prevents the welding current passing throughthe engine and causing fires or melting at bearings,which may lead to pitting or other material damage).Never carry out welding work on the engine or en-gine-mounted units.
Never position the welding power supply cable ad-jacent to, or crossing MTU plant wiring harnesses.(The welding current can be induced in the wiringharnesses, which could damage the electrical unit).The ground connection for the welding unit must notbe attached more than 60 cm from the welding point.If components (e.g. exhaust manifold) are to bewelded, they must first be removed from the engine.When carrying out work on MTU electronics compo-nents, it is not necessary to remove connectors pro-vided that the master switch for power supply hasbeen moved from “ON” to “OFF” and the cable isdisconnected from the battery negative and positiveterminals.

K000.000.01 Preservation – PrefaceLow operating and maintenance costs as well as operational reliability and availability depend on maintenance andservicing being carried out in compliance with our specifications and instructions.These instructions differentiate between preservation, represervation and depreservation.Preservation must be carried out on– New or overhauled engines, following the test run preservation is carried out by DDC/MTU, but may be omitted if
the engine is to be put into immediate operation.– Engines being withdrawn from operation for a period exceeding three months, as soon after the final operating
period as possible.Preservation is adequate for storage for a period up to– 12 months under favourable storage conditions.
– 6 months under unfavourable storage conditions, e.g. high humidity, salt-laden atmosphere, pronounced tempera-ture fluctuations, etc.
On conclusion of the preservation period, carry out represervation at the required intervals.Represervation is adequate for a storage period of up to– 6 months under favourable storage conditions.– 3 months under unfavourable storage conditions, e.g. high humidity, salt-laden atmosphere, pronounced tempera-
ture fluctuations, etc.Engines in special packing do not need to be represerved as long as the permissible relative humidity is not ex-ceeded in the packaging enclosure room.– See inspection specification for Special Packing.Only preservation agents approved by the manufacturer may be used for preservation and represervation.
– See Fluids and Lubricants Specification.These services may be omitted if– they cannot be completed due to operationally required special equipment (e.g. test stand).– the specified component is not fitted on the diesel engine.Before- and after-operation services on the engine must be carried out in accordance with the Operating Instruc-tions (Section C).NOTE:
The operations and tasks required for preservation, represervation and depreservation must be carried out in the recommended se -quence.
They are specified by 3-digit and 8-digit codes.

K000.000.09 Description of Services
K001 Clean engine
Clean engine externally and check for corrosion. If necessary, remove rust spots and renew paint.NOTE:
Do not use organic detergents to clean rubber or synthetic components. Wipe with a dry cloth only.
K002 Preserve fuel system
Connect the fuel delivery pump suction line to a separate tank,which should be filled with– injection pump testing oil, to DIN ISO 4113 or– Diesel fuel with 10% corrosion inhibitor oil, for internal preservation.If possible, preserve the fuel system when the engine is hot. (Preservation is carried out during the preservationrun, 004)
K003 Preserve engine coolant system
NOTE:
Engine coolant systems are usually filled with prepared engine coolant and, therefore, protected from corrosion.
Fill engine coolant system with coolant containing 2% corrosion inhibitor oil or 50% antifreeze. The coolant pre-serves the engine during the preservation run.The coolant should be allowed to remain in the engine to provide protection against corrosion.Only drain the coolant at ambient temperatures
– below 0 °C for coolant / corrosion inhibitor oil emulsions– Below –40 °C for coolant / antifreeze emulsions
K004 Perform preservation run
Run the engine approximately 20 minutes at idling speed.
K005 Spray corrosion inhibitor oil into air manifolds
Remove plugs from air manifolds.Turn engine on starter.Spray corrosion inhibitor oil into air manifolds.Insert plugs into air manifolds.
– Use only sealing rings which are in perfect condition.
K006 Spray corrosion inhibitor oil onto turbocharger compressor wheels
Disconnect air pipework from turbochargers.Spray compressor wheels and compressor housing with corrosion inhibitor oil while rotating the compressorwheels.Reconnect air pipework.
K007 Seal engine exhaust system
Cover the exhaust outlets at the turbocharger with blanking plates so that they are sealed against air and moisturepenetration.NOTE:
In order to ensure that these plates are not overlooked when the engine is returned to service, they must be shaped in such a w ay asto project beyond the flanges at a certain point. Paint the projections bright red and fold them back.
