gasoline will cause problems.

cover it to give protection from dust and
dirt.

tive cover that does not retain moisture.

breathe which allows condensation to
form and will cause your unit to rust.

_,CAUTION: Never store the lawn mower
with gasoline in the tank inside a building
where fumes may reach an open flame or
spark. Allow the engine to cool before
