STORAGE
For long-term storage of the mister, first perform all regular maintenance procedures and needed
repairs. Empty the fuel tank. Disconnect the fuel supply line from the carburetor and depress the
primer bulb until fuel stops discharging from the fuel-return line.
Start the engine and allow it to run until it stops. Pull the starter cord a few times to remove any excess
fuel from the engine. Remove the spark plug and insert a small amount of oil into the cylinder. Slowly
pull the starter cord and bring the piston to a position closest to the spark plug hole. Re-install the
spark plug. Apply a thin coating of oil to all the metal surfaces and store the mister in a dry place.
