Long-term Storage
1. Remove the fuel cap, tip the unit and drain the fuel
into an approved container. Reinstall the fuel cap.
2. Start the engine and allow it to run until it stalls.
This ensures that all fuel has been drained from the
carburetor.
3. Allow the engine to cool. Remove the spark plug
and put 5 drops of any high-quality motor oil into the
cylinder. Pull the starter rope slowly to distribute the
oil. Reinstall the spark plug.
4. Thoroughly clean the unit and inspect it for any loose
or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts or bolts.
Preparing the Unit for Use after Long-term
Storage
1. Remove the spark plug. Tip the unit and drain all of
the oil from the cylinder into an approved container.
Reinstall the spark plug.
2. Change the oil. Refer to Changing the Oil.
Note: Do not use fuel that has been stored for more
than 30 days. Dispose of old fuel and oil
according to federal, state and local regulations.
FUEL SYSTEM
Empty the fuel system before storage for 30 days or
longer. Drain the gas tank, start the engine and let it run
until the fuel lines and carburetor are empty. Use fresh
fuel next season. Under OIL AND FUEL section of this
manual, see message labeled IMPORTANT regarding
the use of blended and E85 fuel in your engine.
Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or fuel storage
container. Follow the mix instructions found on stabilizer
