Long Term Storage
Whenever the unit will not be used for 30 days or longer, use the following
procedures to prepare it for storage:
• Clean external parts thoroughly.
• Drain all the fuel from the fuel tank.
IMPORTANT!
Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30)
days, ninety (90) days when a fuel stabilizer is added.
CAUTION!
Gasoline stored in the carburetor for extended periods can cause hard
starting and could also lead to increased service and maintenance cost.
• Remove the remaining fuel from the fuel lines and carburetor.
1. Prime the primer bulb until no more fuel is passing through.
2. Start and run the engine until it stops running.
3. Repeat steps 1 and 2 until the engine will no longer start.
• Remove the spark plug and pour about 1/4 ounce of engine oil into the cyl-
inder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times
so oil will evenly coat the interior of the engine. Reinstall the spark plug.
• Before storing the unit, repair or replace any worn or damaged parts.
• Remove the air cleaner element from the carburetor and clean it thorough-
ly with soap and water. Let dry and reassemble the element.
• Store the unit in a clean, dust-free area.
