Long Term Storage
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.

IMPORTANT!
All stored fuels should be stabilized with a
fuel stabilizer such as STA-BIL™, if oil
with fuel stabilizer is not used.
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.
Prime the primer bulb until no more
fuel is passing through.
Start and run the engine until it stops
running.
Repeat steps 1 and 2 until the engine
will no longer start.
