The following work is required for engines
that have already been in operation (distance
of over 300 km or running time of over 6
operating hours):
X
Drain off engine oil and replace the oil filter.
Add initial operation oil compliant with
Sheet No. 225.6.
X
Fill or top up the engine cooling system with
the specified coolant. Before refilling cool-
ant, note the quality of the previously filled
anticorrosion/antifreeze (
Y
page 50).
X
Carry out protective measures for the fuel
system.
X
Warm up the engine at medium engine
speeds and allow it to run for approximately
5 to 10 minutes at operating temperature
(coolant temperature 75 to 95 †).
X
Switch off the engine and check the oil level
(
Y
page 34).
X
Hermetically seal all engine openings.
X
Drain off the coolant completely for
engines that have been removed. Unscrew
the coolant drain plug in the crankcase to
do so.
Re-commissioning
X
Remove all plugs or rags that have been fit-

X
Tension the poly-V-belt as per the regula-
tions.
X
Renew the engine oil and replace the oil fil-
ter before re-commissioning.
X
Add coolant. Observe the concentration of
anticorrosion/antifreeze additives. Before
refilling coolant, note the quality of the pre-
viously filled anticorrosion/antifreeze
(
Y
page 50).
X
New engines: add initial operation oil com-
pliant with Sheet No. 225.6.
X
For engines that have already been in oper-
ation (distance over 300 km or running time
of over 6 operating hours): before starting
the engine, lubricate the lubrication points
on the engine as necessary, e.g. the ball
couplings of the engine brake.
X
Start the engine and leave it running until
it is at operating temperature (coolant tem-
perature approximately 75 to 95 †). While
doing so, observe the indicators for oil pres-
sure, coolant temperature and oil temper-
ature.
