VRR Storage Common Sense Recommendations:

The procedure below is taken from Kohler’s training manual. While we agree with it’s procedure, it starts with the condition of “If the engine will be out of service for two months or more…”. This is where we advise you to start and run your engines every month or two and run it long enough to charge the battery and reach normal operating temperatures. This will:

1) Avoid the need to perform the procedure for storage.

2) Lubricate and drive condensation off parts.

3) Inform you earlier of any need for service.

4) Freshen the fuel system.

5) Blow out any carbon flakes.

6) Activate corrosion inhibitors in the oil.

7) Cost less than performing the storage procedure.

8) Provide you the confidence of a running engine and allows you to run the engine if desired, rather than acknowledge that a treatment has been made and it should not be run till I need it.

9) Finally, for many engines prone to nesting, kill any active nests.

Kohler’s Storage Recommendations:

If the engine will be out of service for two months or more, use the following storage procedure.

1.   Clean the exterior surfaces of the engine. On Electronic Fuel Injected (EFI) engines, avoid spraying water at the wiring harness or any of the electrical components.

2.   Change the oil and oil filter while the engine is still warm from operation. See “Change Oil and Oil Filter” in Section 6.

3.   The fuel system must be completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration. If you choose to use a stabilizer, follow the manufacturer’s recommendations, and add the correct amount for the capacity of the fuel system.  Fill the fuel tank with clean, fresh gasoline. Run the engine for 2 to 3 minutes to get stabilized fuel into the rest of the system. Close the fuel shut-off valve when the unit is being stored or transported.  To empty the system, run the engine until the tank and the system are empty.

4.   Remove the spark plugs and add one tablespoon of engine oil into each spark plug hole. Install the spark plugs, but do not connect the plug leads.  Crank the engine two or three revolutions.

5.   On equipment with an EFI engine, disconnect the battery or use a battery minder to keep the battery charged during storage.

6.   Store the engine in a clean, dry place.
