Preparations
At the time of initial commissioning of a
new or overhauled engine make sure to
have observed the “Technical Information
for the installation of MAN Diesel en-
gines”.

1 Oil filler neck on valve cover
Before daily starting the engine, check
fuel level, coolant level and engine oil
level and replenish, if necessary.
The notches in the dipstick indicate the
highest and lowest permissible oil levels.
Marking the dipstick
As a rule oil dipsticks of marine propulsion
engines are not marked by the manufac-
turer since the final installed position is
unknown. Therefore, they should be
marked after engine installation.
Proceed as follows:
D
Fill with minimum oil quantity recom-
mended for the respective engine type.
After this initial filling wait about
1/2 hour until the entire oil has col-
lected in the oil sump
D
Pull out dipstick and mark minimum oil
level visible on dipstick
D
Thereafter fill up to maximum oil sump
capacity, wait about 1/2 hour and mark
maximum oil level visible on dipstick
D
After refilling with oil, rotate the engine
with the starter and move the shut-
down lever to “stop” at the same time
until the oil pressure warning light goes
out and the oil pressure gauge shows a
pressure. Then start the engine and
allow it to run at medium speed for a
few minutes. Check oil pressure and
tightness of system. Then shut down
the engine. After about 20 minutes,
check the oil level. The oil level should
now be at the upper notch of the dip-
stick, but not higher.
Add any necessary oil to the upper dip-
stick mark.
Caution:
Do not add so much engine oil that the
oil level rises above the max. marking
on the dipstick. Overfilling will result in
damage to the engine.
The oil required in the sump is specified in
the “Technical Data” at the end of these
Instructions.
Note:
The oil required to fill the oil filters and
pipes depends upon the engine equip-
ment and use and must be determined
individually at the time of initial com-
missioning (Make a note of the deter-
mined quantity).
Ensure outmost cleanliness when handl-
ing fuels, lubricants and coolants.
Use only approved fuels, lubricants
etc. (see brochure “Fuels, lubricants
etc.”). Otherwise the manufacturer’s
warranty will become null and void.
