Decommissioning and recommissioning

10.4 Recommissioning of shutdown engines

A routine and careful restart of new or already run engines has a major effect on their operating safety and
residual life. The basic aim should be to preserve the engines directly after decommissioning. In this con­
text the specifications in accordance with the MAN Works Standard M3069 should be followed.
User tip
Ex Works the engines are preserved in accordance with Works Standard M3069.
The Works Standard is available from the customer service department at the Nuremberg plant.
If the engine was not preserved before shutdown there is a danger of corrosion to cylinder liners, piston
rings and valves, in particular if the suction and exhaust openings have not been sealed and storage has
been outside. Foreign substances that have ingressed, including rainwater and the like necessitate, among
other actions, a complete dismantling of the engine.
A distinction must therefore be made between the commissioning procedures of preserved and non-pre­
served engines:
10.4.1 Commissioning of preserved engines compliant to
MAN Works Standard M 3069
1. Remove external preservation. Never use a high pressure cleaner for this.
2. Remove caps from intake and exhaust openings.
3. Check the cooling system, add antifreeze according to the list of fuels, lubricants and coolants (see pub­
lication entitled "Fuels, lubricants and coolants..."), check concentration and correct as necessary.
4. Check engine oil level and add fresh approved engine oil if necessary.
5. Add fuel, bleed the system.
Check for correct functioning of the monitoring and emergency stop device.
6. Check condition and proper installation of elastic fasteners, such as V-belts, coolant hoses and charge-
air hoses. Retighten if necessary.
7. Crank the engine with the starter without filling until the oil pressure rises, in so doing actuate the starter
for a maximum of 5 seconds.
8. Enable filling and start engine.
9. Check engine for possible leaks, check for abnormal noises, observe oil pressure and temperatures.
Gradually increase the engine load.
10.After a max. of 25 operating hours, drain preservation oil from engine and change oil filter; fill engine
with fresh approved engine oil.

Carefully read through the Operating Instructions before starting any work!
This particularly applies to the General Safety Instructions section
and the safety instructions in the various chapters.
