5.10 Product preservation
• If the engines are not to be used for 6 months, they must
be protected by carrying out the operations described in
Engine storage (up to 6 months) (Par. 5.11).
• If the engine is still not in use after the first 6 months, it
is necessary to carry out a further operation to extend the
protection period (more than 6 months) (Par. 5.12).
• If the engine is not to be used for an extended period, the
protective treatment procedure must be repeated within 24
months of the previous one.
5.11 Engine storage up to 6 months
Before storing the engine check that:
• The environments are not humid or exposed to bad weather.
Cover the engine with a proper protective sheet against
dampness and atmospheric contaminants.
• The place is not near electric panel.
• Avoid storing the engine in direct contact with the ground.
5.12 Engine storage over 6 months
Follow the steps described in Par. 5.11.
1. Engine oil replacement
2. Refuel with fuel additives for long storage.
The following additives are recommended:
DEFA Fluid Plus (Pakelo Lubricants),
Diesel Treatment (Green Star),
Top Diesel (Bardhal),
STP® Diesel Fuel Injector Treatment.
3. With expansion tank: make sure that the coolant is up to
the MAX level.
4. Without expansion tank: Top liquid up until the pipes
inside the radiator are covered by about 5 mm. Do not
overfill the radiator, but leave room for the fuel to expand.
5. Start the engine and keep it idle at minimum speed for 2
minutes.
6. Bring the engine to 3/4 of the MAX speed for 5÷10 minutes.
7. Turn off the engine.
8. Completely empty the fuel tank.
9. Spray SAE 10W-40 on the exhaust and intake manifolds.
10. Seal the exhaust and intake ducts to prevent foreign
bodies from entering.

INFORMATION ABOUT MAINTENANCE
Important
(Par.
6.1).
11. When cleaning the engine, if using a pressure washer
or steam cleaning device, avoid directing the nozzle on
electrical components, cable connections and sealed
rings (oil seals etc). If cleaning engine with a pressure
washer or steam cleaner, it is important to maintain
a minimum distance of at least 200mm between the
surface to be washed and the nozzle - avoiding absolutely
electrical components such as alternators, starter motors
and engine control units (ECU).
12. Treat non-painted parts with protective products.
13. Fill the AdBlue tank to the MAX level allowed.
If the engine protection is performed according to the
suggestions indicated no corrosion damage should occur.
5.13 Engine starting after storage
1. Remove the protective sheet.
2. Use a cloth soaked in degreasing product to remove the
protective treatment from the external parts.
3. Inject lubricating oil (no more than 2 cm3) into the intake
ducts.
4. Refill the tank with fresh fuel.
5. Make sure that the oil and the coolant are up to the MAX
level.
6. Proceed with the disposal of the AdBlue contained in
the tank; replace the AdBlue pump filter and wash the
AdBlue tank/circuit with hot distilled water.
7. Check the AdBlue injector at an authorized KOHLER
workshop.
8. Start the engine and keep it idle at minimum speed for a
two about minutes.
9. Bring the engine to 75% of MAX rated speed for 5 to 10
minute.
10. Stop

container.
Warning
• Over time, lubricants and filters lose their properties, so it is
important consider whether they need replacing, also based
on the criteria described in
11. Replace the filters (air, oil, fuel) with original spare parts.
