It is important to prevent gum deposits from forming in essential fuel system parts, such
as the carburetor, fuel filter, fuel hose or tank during storage. Alcohol-blended fuels (also
called gasohol, ethanol, or methanol) attract moisture, which leads to separation and
formation of acids during storage. Acidic fuel and gum deposits can damage the engine's
fuel system while in storage. Effects of old, stale, or contaminated fuel are not covered
under warranty.
NOTE: Using a fuel stabilizer when storing gasoline will help prevent problems related
to ethanol alcohol in outdoor power equipment engines. Always follow the instructions
provided by the fuel stabilizer manufacturer to mix and use correctly.
Overfilling the fuel tank can result in carbon canister damage (if equipped), poor engine
performance, and void the warranty. To avoid damaging the carbon canister, poor engine
performance, and voiding the warranty, do not fill the fuel tank above the maximum level.
1. Check fuel with generator on a level surface with the engine off.
2. Read fuel gauge (if equipped) and fill fuel tank if needed. For fuel gage location see
the COMPONENT LOCATION section of this manual.
3. Do not use gasoline that is older than 30 days. Use only clean and fresh regular
unleaded gasoline with a minimum octane rating of 87. Do not mix oil with gasoline.
Do not use gasoline that contains more than 10% ethyl alcohol. E15, E20, and E85
are not approved fuels and should not be used.
4. Do not to fill the fuel tank above the maximum fuel level to allow room for fuel
expansion. For fuel capacity see the SPECIFICATIONS section of this manual.
