 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.
 Drain all the fuel from the fuel tank.
IMPORTANT!
All stored fuels should be stabilized
with a fuel stabilizer such as Sta-Bil™ if
Shindaiwa One 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.
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.

CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.

 Remove the spark plug and pour

about 7 grams 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 re-
place any worn or damaged parts.
 Remove the air cleaner element from
the unit and clean it as outlined on
page 10.
 Store the unit in a clean, dust-free area.
