Troubleshooting - Craftsman 917.377800 Owner's Manual

• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to give protection from dust and dirt.
• Cover your unit with a suitable protective
cover that does not retain moisture. Do not
use plastic. Plastic cannot breathe which
allows condensation to form and will cause
your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
ACAUTION: 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
storing in any enclosure.
