STORAGE INSTRUCTIONS
This engine should be started at least once a month and run for at
least 10 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.
Never store the engine with the fuel in the
tank indoors or in an enclosed or poorly ven-
tilated area. Fumes can reach an open flame,
spark, or pilot light as on a furnace, water
heater, or clothes dryer and ignite.
1.
Run the engine for about five (5) minutes to warm it.
•
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 "gasohol"
was used, drain the fuel tank, then run the engine until it stops
from lack of fuel.
Drain the fuel into an approved container,
outdoors and away from open flame. Be sure
the engine is cool.
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
(Figure 5). Refill it with fresh oil. See the "BEFORE STARTING
ENGINE" section 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.
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 dirt, oil and grease from the cylinder, cylinder head,
fins, blower housing, rotating screen and muffler area.
6.
Close the fuel shut-off valve, if equipped.
OTHER STORAGE TIPS
1.
Do not store gasoline from one season to another.
2.
Use only plastic gasoline containers. Rust and/or dirt in metal
gasoline containers can cause problems.
3.
Store the equipment in a clean and dry area.
