Storage
If the engine will be out of service 30 days or more, use
the following storage procedure:
1. Clean the exterior surfaces of the engine. Avoid
spraying water at the wiring harness or any of
the electrical components.
2. Change the oil and filter while the engine is still
warm from operation. See Change Oil and
Change Oil Filter on pages 9 and 10.
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
2-3 minutes to get stabilized fuel into the rest of
the system. Close fuel shut-off valve when unit is
being stored or transported.
To empty the system, run the engine until the
tank and fuel system are empty.
4. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install the
plugs, but do not connect the plug leads. Crank
the engine two or three revolutions.
5. Store the engine in a clean, dry place.
Troubleshooting
When troubles occur, be sure to check the simple causes which, at first, may seem too obvious to be considered.
For example, a starting problem could be caused by an empty fuel tank. Some common causes of engine troubles
are listed in the following table.
Do not attempt to service or replace major engine components, or any items that require special timing or
adjustment procedures. Have your Kohler Engine Service Dealer do this work.
