    Storage

    Storage Safety

    • Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    • Fuel fumes are highly flammable, explosive, and dangerous if inhaled. If you store the product in an area with an open flame, the fuel fumes may ignite and cause an explosion.

    • Do not store the machine in a house (living area), basement, or any other area where ignition sources may be present, such as hot water and space heaters, clothes dryers, furnaces, and other appliances.

    • Do not tip the machine either forward or backward with fuel in the fuel tank; otherwise, fuel may leak out of the machine.

    • Do not store the machine with its handle tipped down onto the ground; otherwise, oil may leak into the engine cylinder and onto the ground, and the engine may not start.

    Storing the Machine

    1. On the last refueling of the year, add fuel stabilizer to fresh fuel as directed by the fuel stabilizer manufacturer.

      Important: Do not store fuel longer than that suggested by the fuel stabilizer manufacturer.

    2. Run the engine for 10 minutes to distribute the conditioned fuel through the fuel system.

    3. Run the machine until the engine runs out of fuel.

    4. Prime the engine and start it again.

    5. Allow the engine to run until it shuts off. When you can no longer start the engine, it is sufficiently dry.

    6. Allow the engine to cool.

    7. Remove the key.

    8. Clean the machine thoroughly.

    9. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting.
