CLEANING
J_ WARNING:
To avoid serious personal injury, always
turn the unit off and allow it to cool before you clean or
service it.
Use a small brush to clean off the outside of the unit. Do not use
strong detergents. Household cleaners that contain aromatic oils
such as pine and lemon, and solvents such as kerosene, can damage
plastic housing or handle. Wipe off any moisture with a soft cloth.
STORAGE

an open flame or spark.

that has been stored for more than 60 days. Dispose of the old
gasoline in accordance to Federal, State, and Local regulations.

drops of high quality motor oil into the cylinder. Pull the starter
rope slowly to distribute the oil. Reinstall the spark plug.
