Store in a cool, dry place, out of reach of children, and away from open flames or sparks.
Remove the spark plug, add a teaspoon of engine oil into the cylinder, pull the starter cord slowly to distribute oil, and reinstall the spark plug.

CAUTION! Never store the unit with fuel in the tank for more than 30 days without stabilizer.
