Fuel

Depending on the region where you operate your equipment, fuel formulations may
deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as
little as 30 days and may cause damage to the carburetor and/or fuel system. Please
check with your servicing dealer for local storage requirements.
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard
starting, and it leaves gum deposits that clog the fuel system. If the gasoline in
your engine deteriorates during storage, you may need to have the carburetor
and other fuel system components serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor
without causing functional problems will vary with such factors as gasoline
blend, your storage temperatures, and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank promotes fuel
deterioration. Very warm storage temperatures accelerate fuel deterioration.
Fuel deterioration problems may occur within a few months, or even less if the
gasoline was not fresh when you filled the fuel tank.
The Distributor's Limited Warranty does not cover fuel system damage or engine
performance problems resulting from neglected storage preparation.
You can extend fuel storage life by adding a fuel stabilizer that is formulated for
that purpose, or you can avoid fuel deterioration problems by draining the fuel
tank and carburetor.
