STORAGE

WARNING
Never store an inverter 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 ines, fuel passages and the engine. Ihis corrosive buildup restricts the flow of fuel, preventing an engine from starting after a prolonged storage period._ Proper care should be taken to prepare the inverter for any storage

1. Clean the inverter as outlined in Cleaning the inverter
2. Siphon all gasoline from the fuel tank as best as possible.
3. Start the engine and allow the inverter to run until all the remaining gasoline in the fuel lines and carburetor is consumed and the engine shuts off.
4. Drain any remaining fuel from the float bowl. See Draining the Float Bowl on page 20.
5. Change the oil (see Changing Engine Oil on page 19).
6. Remove the spark plug (see Spark Plug Maintenance on page 21) 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 ill distribute the oil and protect the cylinder wall from corroding during storage.
7. Replace the spark plug (see Spark Plug Maintenance on page 21).
8. Move the inverter to a clean, dry place for storage.
