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.
10.3.2.1 Preservation of the fuel system
The fuel system and the engine combustion chambers are preserved by operating with corrosion-inhibiting
fuel. Corrosion-inhibiting fuel is a mixture of conventional diesel fuel and
2% (by volume) Autol Desolite K corrosion inhibitor.
The fuel system must be preserved as follows:
S Prepare corrosion-inhibiting fuel in a container.
S Connect the engine fuel system to this container.
S Operate the warmed-up engine with corrosion-inhibiting fuel for 3 minutes at rated speed.
S Operate the engine for 2 minutes at idle.
S Stop the engine.
S Close off the openings for suction air and exhaust gas and seal them air tight, with the engine still warm.
NOTE
Damage to property due to incorrect preservation
When the engine is cranked with the starter, the engine may not start so as to allow the combustion
chambers, cylinder liners and valves to be preserved.
Therefore:
S Opening for intake air closed and airtight.
During the preservation of the injection system, injections are made according to the start characteristic
map.
Therefore:
S Supply power to the control unit.
10.3.2.2 Preservation of the intake and exhaust system
S Spray corrosion protection oil (MAN-Part No. 09.11002-0025) into the air intake pipe and exhaust pipe.
S Close off the openings for suction air and exhaust gas and seal them air tight, with the engine still warm.
