TIM-ID: 0000038133 - 001
Transport with flange-mounted gearbox
Illustration is valid for 12/16V 2000 M engines
Lift the engine only with the lifting eyes provided.
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.
The engine must only be transported in installation position, max. permissible diagonal pull with flange-
mounted gearbox is 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.

The product must be installed and accepted in accordance with manufacturers' specifications prior to
initial startup.
All the requisite regulatory approvals must have been granted and all startup requirements fulfilled prior
to initial startup.
Whenever the product is started, always ensure that:
• All maintenance and repair work has been completed.
• All loose parts have been removed from rotating machine components.
• Wearers of cardiac pacemakers or other active medical implants are well clear.
• The operating room is adequately ventilated.
• Exhaust pipework is leak-tight and routed to atmosphere.
• Battery terminals, generator terminals and cables are guarded to preclude accidental contact.
• All personnel is clear of the danger zone represented by moving parts.
Immediately after putting the product into operation, make sure that all control and display instruments
as well as the monitoring, signaling and alarm systems are working properly.
Safety requirements for operation
The operator must be familiar with the controls and displays.
The operator must be aware of the consequences of any operations he/she performs.
During operation, the display instruments and monitoring units must be constantly observed in regard
of present operating status, limit value violation and warning or alarm messages.

TIM-ID: 0000040533 - 005
1.5 Safety requirements for maintenance and repair work
Safety requirements before commencing maintenance and repair work
Have maintenance or repair work carried out by qualified and authorized personnel only.
Allow the product to cool down to less than 50°C (risk of explosion for oil vapors, fluids and lubricants,
risk of burning).
Relieve pressure in fluid and lubricant systems and compressed-air lines which are to be opened. Use
suitable collection vessels with a sufficient filling volume.
Ensure that the operating room is adequately ventilated when changing the oil or working on the fuel
system.
Do not perform maintenance or repair work when the product is running unless:
• expressly instructed to do so.
• the product is running in the low load range and only for as long as necessary to complete the task.
Lock-out the product to preclude undesired starting, e.g. start interlock.
Tag-out the product with a “Do Not Start” sign in the operation room or on the control facility.
Disconnect the battery. Lock the contactor.
Close the main valve on the compressed-air system and vent the compressed-air line when pneumatic
starters are fitted.
Disconnect the control facility from the product.
For starters with pinions made of copper-beryllium alloy:
• Wear a respirator mask (filter class P3). Do not blow out the interior of the flywheel housing or the
starter with compressed air. Clean the interior of the flywheel housing with a class H dust extractor.
• Observe the safety data sheet.
Safety requirements during maintenance and repair work
Take special care when removing vent plugs or plug screws from the product. Hold a cloth over the
screw or plug to prevent discharge of highly pressurized liquids.
Take care when draining hot fluids and lubricants (risk of burning).
Use suitable and calibrated tools only. Observe the specified tightening torques during assembly or dis-
assembly.
Carry out work only on assembles and/or installations which are properly secured.
Never climb up on the lines.
Keep fuel injection lines and connections clean.
Always seal connections with caps or covers if a line is removed or opened.
Fit new seals when re-installing lines.
Avoid damaging lines, particularly the fuel lines.
Ensure that all retainers and dampers are installed correctly.
Ensure that all fuel injection and pressurized oil lines are installed with enough clearance to prevent
contact with other components. Never route fuel or oil lines in the vicinity of hot components.
Do not touch elastomeric seals (e.g. Viton sealing rings) with your bare hands if they have a carbonized
or resinous appearance.
Observe the cooling time for components which have been heated for installation or removal (risk of
burning!).
Always use suitable ladders and work platforms when working above head-height. Ensure that compo-
nents or assemblies are placed on stable surfaces.
