Section 1
Safety and General Information
Storage
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 radiator and
engine. On EFI engines, 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
Filter" in Section 6.
3. The coolant (anti-freeze) mixture should be in
good condition and tested to guard against
freezing in cold temperatures. The recommended
50/50 mixture will normally provide protection
down to temperatures of -37°C (-34°F). If storage
temperatures will fall below this, the cooling
system should be drained completely. A note
should then be attached to the equipment and/or
engine as a reminder to refill the cooling system
before starting.

4. 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 manufacturers
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
carburetor. Close fuel shut-off valve when unit is
being stored or transported.
To empty the system, run the engine until the
tank and system are empty.
5. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install plugs,
but do not connect the plug leads. Crank the
engine two or three revolutions.
6. On units with EFI engines, disconnect the
negative (-) battery cable or use a "battery
minder" trickle charger while the unit is in
storage.
7. Store the engine in a clean, dry place.
