Introduction
This instruction book provides general information
on the engine design, operation and maintenance.
It can also be used as a reference when ordering
spare parts. Reliable and economical operation of
the plant is conditional upon its correct operation
and maintenance in accordance with MAN Diesel &
Turbo’s instructions.Emissions-related maintenance
of the diesel engine shall be performed as speci-
fied in MAN Diesel & Turbo’s instructions and any
additional instructions to that effect included in the
Technical File. Consequently, it is essential that the
engine room personnel are fully acquainted with the
contents of this book and the Technical File.
Every care is taken to ensure that all information in
this instruction book is present and correct.
This book must not, either wholly or partly, be copied,
reproduced, made public or in any other way made
available to any third party without the written consent
to this effect from MAN Diesel & Turbo.
If an instruction book is delivered in another language
than English and doubts arise concerning the trans-
lation, the English text shall prevail.

Description
The book is a basic instruction manual for the particu-
lar engine supplied, with plant-adapted information
such as basic media-system drawings, electrical
wiring diagrams and test bed reports.
The first five sections (500-504) of the book serve
as a guide to engine operation, and the next fifteen
sections (505-519) contain technical descriptions,
spare parts illustrations with appurtenant parts lists,
as well as working cards.
The last section (520) comprises tools.
The engine is divided into a number of main com-
ponents/assemblies, each of which is described in
a section of this book (section 505-519).
Each of these sections starts with technical de-
scriptions of the systems/components, followed by
working cards and the spare parts illustration plates
and parts lists.

General
Proper maintenance, which is the aim of this book,
constitutes the crucial point in obtaining optimum
safety in the engine room. The general measures
mentioned here should therefore be a natural routine
to the entire engine room staff.
Cleanliness
The engine room should be kept clean above and
below the floor plates. If grit or sand blows into the
engine room when the ship is in port, the ventilation
should be stopped and ventilating ducts, skylights,
and doors in the engine room should be closed.
Inparticular,weldingorworkwhichcausesspreading
of grit and chips must be avoided near the engine,
unless this is closed or covered, and the turbochar-
ger air intake filters are covered.
The exterior of the engine should be kept clean and
thepaintwork maintained so that leakagescaneasily
be detected.
Fire
If the crankcase is opened before the engine is cold,
welding and the use of naked light will involve the risk
ofexplosions and fire.Thesameappliestoinspection
of oil tanks and the space below the fooler. Attention
is furthermore drawn to the danger of fire when using
paint and solvents with a low flash point. Porous
insulating material drenched with oil from leakages
is easily inflammable and should be renewed. See
also: "Ignition in crankcase" in section 603.
Order
Hand tools should be placed easily accessible on
tool boards. Special tools should be fastened to tool
panels (if supplied) in the engine room close to the
area of application. No major objects must be left
unfastened, and the floor and passages should be
kept clear.

General
Spares
Large spare parts should, as far as possible, be pla-
ced well strapped near the area of application and
accessible by crane.The spare parts should be well
preserved against corrosion and protected against
mechanical damage. The stock should be checked
at intervals and replenished in time.
Light
Ample working light should be permanently installed
at appropriate places in the engine room, and port-
able working light, in explosion-proof fittings, should
be obtainable everywhere.
Freezing
If there is a risk of damage due to freezing when the
plant is out of service, engines, pumps, coolers, and
pipe systems should be emptied of cooling water.
Warning
The opening of cocks may cause discharge of hot
liquids or gases.The dismantling of parts may cause
springs to be released.
The removal of fuel valves (or other valves in the
cylinder head) may cause oil to run down to the
piston crown, and if the piston is hot, an explosion
may then blow out the valve.
When testing fuel valves with the hand pump, do not
touch the spray holes, as the jet may pierce the skin.
Think out beforehand which way the liquids, gases
or flames will move, and keep clear.
Crankcase work
Check beforehand that the starting air supply to the
engine is shut off.

Feeling over
Whenever repairs or alterations have been made to
the running gear, apply the "Feel-over sequence"
until ensured that there is no undue heating, oil-
mist formation, blow-by, or failure of cooling water
or lubricating oil systems.
Feel-over sequence
Feel-over after 5-15 and 30 minutes' idle running and
finally when the engine is running at full load. See
also "Starting-up sequence" in the section 602.

Turning with air
After prolonged out-of-service periods or overhaul
work which may involve a risk of accumulation of
liquid in the combustion spaces, turning with open
indicator cocks should always be effected, through
at least two complete revolutions.
Check and maintain
Lubricating oil condition, filter elements and mea-
suring equipment.
