STORAGE INSTRUCTIONS

This engine should be started at least once a week and run for at
least 30 minutes. If this cannot be done and the equipment must
be stored for more than 30 days, use the following guidelines to
prepare it for storage.
WARNING: Never store the engine with the fuel in the tank
indoors or in an enclosed, poorly ventilated areas, where
fumes can reach an open flame spark or pilot light as on a
furnace, water heater, or clothes dryer.
1. Run the engine for about five (5) minutes to warm it.
NOTE: Alcohol-blended fuel, or "gasohol", attracts moisture which
can lead to the separation and formation of acids during
storage. This acidic gas can damage internal engine parts.
Methanol, ethanol and grain alcohol all are forms of
gasohol. If you did use "gasohol," drain the fuel tank, then
run the engine until it stops from lack of fuel.
WARNING: Drain the fuel into approved container
outdoors, away from open flame. Be sure the engine is cool.
NOTE: Using a fuel additive such as STA-BIL® fuel stabilizer, or an
equivalent, will prevent gum deposits from forming in the
engine's fuel system.
2. While the engine is still warm, drain the oil from the
crankcase. Refill with it with fresh oil. See BEFORE
STARTING ENGINE on Page 6 for oil recommendations.
3. Remove spark plug and pour about 1/2 ounce (15ml) of
engine oil into the cylinder. Crank slowly to distribute oil.
CAUTION: Avoid spray from the spark plug hole when
cranking the engine slowly.
4. Install the spark plug. Do not connect the spark plug wire.
5. Clean the dirt, oil and grease from the cylinder, cylinder head,
fins, blower housing, rotating screen and muffler area.
6. Close the fuel shut-off valve.
