Please check out UPS for more information.

  • How do I prepare my engine for long-term storage?

    If your unit will not be used for more than one month, prepare it for longer term storage.

    Steps for Long-Term Storage:

    1. Mix an appropriate amount of fuel stabilizer, such as STA-BIL, to fresh gasoline, in the ratio recommended on the stabilizer packaging. Run the engine for five minutes to distribute the stabilizer mixture throughout the fuel system. This will prevent gum, varnish and corrosion build up in you fuel system during long-term storage for up to 12 months.

    2. Empty the unit completely of all fuel.

    3. Store unit as directed in manual.
