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 carburetor
■
and the fuel tank.
To do so:
Prime the primer bulb until no more 1.
fuel is passing through.
Start and run the engine until it stops
2.
running.
Repeat steps 1 and 2 until the engine
3.
will no longer start.
Remove the spark plug and pour
■
about 1/4 oz. of engine 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 thor-
oughly 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 starting, and could also lead to
increased service and maintenance
costs.
IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL™.
NOTE:
Damage resulting from stale or contami-
nated fuel is not covered by the Shindaiwa
warranty policy.
