Ciean the engine and the entire unit thoroughly.
Refer to engine manual for correct engine storage
instructions.
If storing in an unventilated or metal storage shed,
coat metal parts with light oil or silicone to prevent
rust.
Store unit in a clean, dry area.
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. Also, alcohol
blended fuels {called gasohoi or using ethanol or
methanol) can attract moisture which leads to separa
tion and formation of acids during storage. Acidic gas
can damage the fuel system of an engine while in
storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow
the instructions in the engine's Operating &
Maintenance Manual.
