Note: The locking device protects the crankshaft bearings from shocks and vibration damage during engine
transport.
For installation and removal of the transport locking device, follow the instructions
below:
1. The transport locking device must remain installed as long as possible during engine installation in order
to avoid damage.
2. Prior to every engine transport, the transport locking device must be reinstalled on both sides according
to the instructions.
3. If the engine is to be moved together with the generator, the transport locking device for the generator
must also be installed.

1.5 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.
