WARNING
Never store a generator with fuel in the
tank indoors or in a poorly ventilated
area where the fumes can come in
contact with an ignition source such
as a: 1) pilot light of a stove, water
heater, clothes dryer or any other gas
appliance; or 2) spark from an electric
appliance.
NOTICE
Gasoline stored for as little as 60 days can go bad,
causing gum, varnish and corrosive buildup in fuel
lines, fuel passages and the engine. This corrosive
buildup restricts the fl ow of fuel, preventing an engine
from starting after a prolonged storage period.
Proper care should be taken to prepare the generator for
any storage.
1. Clean the generator as outlined in Cleaning the
Generator on page 7-12.
2. Drain all gasoline from the fuel tank as best as
possible.
3. With the fuel shutoff valve open, start the engine
and allow the generator to run until all the remaining
gasoline in the fuel lines and carburetor is
consumed and the engine shuts off.
4. Close the fuel shutoff valve.
5. Change the oil (see Changing Engine Oil on page
7-4).
6. Remove the spark plug (see Spark Plug Service on
page 7-7) and place about 1 tablespoon of oil in the
spark plug opening. While placing a clean rag over
the spark plug opening, slowly pull the recoil handle
to allow the engine to turn over several times. This
will distribute the oil and protect the cylinder wall from
corroding during storage.
7. Replace the spark plug (see Spark Plug Service on
page 7-7) .
8. Move the generator to a clean, dry place for storage.
