Long Term Storage
Whenever the unit will not be used for 30
days or longer, use the following proce-
dures to prepare it for storage:

Clean external parts thoroughly and
apply a light coating of oil to all metal
surfaces.
 Drain all the fuel from the fuel tank.
IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL™, if
oil with fuel stabilizer is not used.
To remove the remaining fuel from the
fuel lines and carburetor and with the fuel
drained from the fuel tank.
 Remove the spark plug and pour about
1/4 ounce of 2-cycle mixing oil into the
cylinder 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 thoroughly with
soap and water. Let dry and reassemble
the element.
 Store the unit in a clean, dust-free area.
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
1. Prime the primer bulb until no more fuel
is passing through.
2. Start and run the engine until stops
running.
3. Repeat steps 1 and 2 until the engine will
no longer start.
