1.1 General conditions
General
In addition to the instructions in this publication, the applicable country-specific legislation and other com‐
pulsory regulations regarding accident prevention and environmental protection must be observed. This
state-of-the-art engine has been designed to meet all applicable laws and regulations. The engine may
nevertheless present a risk of injury or damage in the following cases:
• Incorrect use
• Operation, maintenance and repair by unqualified personnel
• Modifications or conversions
• Noncompliance with the Safety Instructions
Correct use
The engine is intended solely for use in accordance with contractual agreements and the purpose envis‐
aged for it on delivery. Any other use is considered improper use. The engine manufacturer accepts no
liability whatsoever for resultant damage or injury in such case. The responsibility is borne by the user
alone.
Correct use also includes observation of and compliance with the maintenance specifications.
Modifications or conversions
Unauthorized modifications to the engine represent a safety risk.
MTU will accept no liability or warranty claims for any damage caused by unauthorized modifications or
conversions.
Spare parts
Only genuine MTU spare parts must be used to replace components or assemblies. MTU accepts no
liability whatsoever for damage or injury resulting from the use of other spare parts and the warranty shall
be voided in such case.
Reworking components
Repair or engine overhaul must be carried out in workshops authorized by MTU.

1.2 Personnel and organizational requirements
Personnel requirements
Work on the engine must only be carried out by appropriately qualified and instructed personnel.
Observe the minimum legal age.
Responsibilities of the operating, maintenance and repair personnel must be specified by the operating
company.
Organizational measures
This publication must be issued to all personnel involved in operation, maintenance, repair or transporta‐
tion.
Keep it handy in the vicinity of the engine such that it is accessible to operating, maintenance, repair and
transport personnel at all times.
Use the manual as a basis for instructing personnel on engine operation and repair. In particular, person‐
nel must have read and understood the safety-relevant instructions.
This is especially important for personnel who work on the engine only on an occasional basis. These
persons shall receive repeated instruction.
Use the Spare Parts Catalog to identify spare parts during maintenance and repair work.
Working clothes and protective equipment
Wear proper protective clothing for all work.
Depending on the kind of work, use the necessary personal protective equipment.

Illustration is essentially valid for 12/16V 2000 M engines
Only use the lifting eyes provided to lift the engine.
The eyebolts mounted at the driving end and on the gearbox must not be used for transporting plants
with flange-mounted gearboxes.
Only use transport and lifting devices approved by MTU.
Take the engine's center of gravity into account.
8 | Safety | MS150062/01E 2012-01
TIM-ID: 0000002620 - 003

The engine must only be transported in installation position, max. permissible diagonal pull 10°.
If the engine is supplied with special aluminum foil packing, lift the engine at the lifting eyes of the bear‐
ing pedestal or use a means of transportation which is appropriate for the given weight (forklift truck).
Install the crankshaft locking device and the locking screws for the engine mounts prior to engine trans‐
portation.
Secure the engine against tilting during transport. In particular when going down inclines or ramps, the
engine must be secured against moving and tilting.
Setting the engine down after transport
Only set down engine on a firm, level surface.
Make sure that the consistency and load-bearing capacity of the ground or support surface is adequate.
Never set an engine down on the oil pan unless expressively authorized to do so by MTU on a case-to-
case basis.

1.4 Safety regulations for startup and operation
Safety requirements for initial operation
Prior to initial operation of the unit, install the assembly or unit according to the specifications and check
the installation according to the MTU specifications.
Before putting the device or plant into operation, always ensure:
• that all maintenance and repair work is completed,
• that all loose parts have been removed from rotating machine components,
• that nobody is in the danger area of moving machine parts.
Immediately after putting the device or plant into operation, make sure that all control and display instru‐
ments as well as the signaling and alarm systems work properly.
Safety requirements for operators
The procedures for cases of emergency must be practiced regularly.
The operator must be familiar with the control and display elements.
The operator must be familiar with the consequences of any operations performed.
During operation, the display instruments and monitoring units must be permanently observed with re‐
gard to present operating status, violation of limit values and warning or alarm messages.
The following steps must be taken if a malfunction of the system is recognized or reported by the system:
• inform supervisor(s) in charge,
• analyze the message,
• if required, carry out emergency operations e.g. emergency engine stop.
Engine operation
The following conditions must be fulfilled before starting the engine:
• Wear ear protection.
• Ensure that the engine room is well ventilated.
• Do not inhale engine exhaust gases.
• Ensure that the exhaust system is free of leaks and that the gases are discharged to atmosphere.
• Mop up any leaked or spilt fluids and lubricants immediately or soak up with a suitable binding agent.
• Protect battery terminals, battery-charger terminals and cables against accidental contact.
• When the engine is running, never release coolant, oil, fuel, compressed-air or hydraulic lines.
Operation of electrical equipment
When electrical equipment is in operation, certain components of these appliances are electrically live.
Observe the safety instructions for these devices.
