STORAGE
2. After washing the tiller, wipe dry all accessible surfaces.
3. Start the engine outdoors, and let it run until it reaches normal operating
temperature to evaporate any water remaining on the engine.
4. While the engine is running, operate the clutch lever to expel water from
the pulleys, belts, and other moving items.
5. Stop the engine and allow it to cool.
6. After the tiller is clean and dry, touch up any damaged paint and coat
other areas with a light film of oil. Lubricate the throttle cable core with a
silicone spray lubricant.

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 recommendations.
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 tiller 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.
