4.23 Engine conservation
If the engine is to be shut down for a longer period
of time (e.g. over winter), we recommend the fol-
lowing measures to avoid corrosion:
● Clean engine and cooling system: With cold
cleansing agent and water jet or, even better,
with steam cleaning equipment.
● Run the engine warm and shut it down.
● Drain the still warm engine oil and fill in anti-
corrosion engine oil.
● Drain and catch the fuel from the fuel tank, mix
it well with 10% anti-corrosion oil and fill it back
in. Instead of mixing the fuel with anti-corro-
sion oil you may also fill the tank with injection
pump testing oil with anti-corrosive properties
(e.g. Calibration fluid B).
● Then run the engine for 10 minutes, so that
lines, filter, pump and nozzles are filled with
the conserving mixture and the new engine oil
is distributed to all parts.
● Take the cylinder head cover off, spray the
rocker chamber with a mixture of diesel fuel
and 10% anti-corrosion oil. Then fasten the
cover again.
● Crank the engine several times to spray the
combustion chamber (throttle lever in stop po-
sition).
● Take the V-belt off and spray the grooves of
the V-belt pulleys with anti-corrosion oil. Re-
move the anti-corrosion oil before taking the
machine back into service.
● Close air intake on air filter and exhaust open-
ing tightly.

Note
Depending on weather conditions these conserva-
tion measures will protect the machine for approx.
6 to 12 months.
Before taking the machine back into service you
must drain off the conservation oil and replace it
with engine oil (see table of fuels and lubricants)
according to API-(MIL-) classification.
Anti-corrosion oils are all oils which comply with
the specification MIL-L-21260 B or TL 9150-037/2
o Nato Code C640/642.
