WARNING

 

 

 

 

Running engines produce heat. Engine parts, especially muffler,

 

 

become extremely hot.

 

 

 

 

Severe thermal burns can occur on contact.

 

 

 

 

 

 

 

 

Combustible debris, such as leaves, grass, brush, etc. can catch fire.

Fuel Recommendations

Fuel must meet these requirements:

Clean, fresh, unleaded gasoline.

A minimum of 87 octane/87 AKI (91 RON). High altitude use, see below.

Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable.

CAUTION: Do not use unapproved gasolines, such as E85. Do not mix oil in gasoline or modify the engine to run on alternate fuels. This will damage the engine components and void the engine warranty.

Fuel Shut-off Valve (optional)

 

 

 

 

 

 

 

 

 

To protect the fuel system from gum formation, mix a fuel stabilizer into the fuel. See
