STORAGE
&CAUTION: NEVER STORE YOUR
EDGER INDOORS OR IN AN EN-
CLOSED, POORLY VENTILATED AREA
IF GASOLINE REMAINS IN THE TANK
FUMES MAY REACH AN OPEN FLAME,
SPARK OR PILOT LIGHT FROM A FUR-
NACE, WATER HEATER, CLOTHES
DRYER, ClGARETI'E, ETC.
EDGER
•Clean the edger thoroughly;remove all debris and
wipethe unitdry.
•Inspectthe edger for worn or damaged parts and
tightenall loose hardware.
•OilallpointsdescitbedintheLubrlcaUon paragraph
in the Customer Responsibilities section of this
manual.
•Store the edger in a protected area and cover for
additionalprotection.
IMPORTANT: A YEARLY CHECKUP OR TUNE-UP
BY A SEARS SERVICE CENTER IS A
GOOD WAY OF ENSURING THAT
YOUR EDGER WILL PROVIDE
MAXIMUM PERFORMANCE FORTHE
NEXT SEASON.
ENGINE
IMPORTANT: IT IS IMPORTANTTO PREVENT GUM
DEPOSITS FROM FORMING IN ES-
SENTIAL FUEL SYSTEM PARTS
SUCH AS THE CARBURETOR, FUEL
FILTER, FUEL HOSE, OR TANK DUR-
ING STORAGE. ALSO, EXPERIENCE
INDICATES THAT ALCOHOL-
BLENDED FUELS (CALLED GASO-
HOLOR USING ETHANOLORMETHA-
NOL) CAN ATTRACT MOISTURE
WHICH LEADSTO SEPARATION AND
FORMATION OF ACIDS DURING
STORAGE. ACIDIC GAS CAN DAM-
AGE THE FUEL SYSTEM OF AN EN-
GINE WHILE IN STORAGE.
To preventenginedamage ( ifedger isnotusedformore
than 30 days) follow the stepsbelow.
To remove gasoline,runthe engineuntilthe tank is
empty and the engine stops.
Ifyoudonotwanttoremovegasoline,a fuelstabilizer
(suchas SearsCraftsmanfuel stabilizerNo.33500)
may be added to any gasoline left in the tank to
minimize gum deposits and acids. If the tank is
almostempty, mixstabilizerwithfreshgasolinein a
separate containerand add some tothe tank. AL-
WAYS FOLLOWlNSTRUCTIONS ON STABlUZER
CONTAINER. THEN RUN ENGINE AT LEAST 10
MINUTES AFTER STABILIZER IS ADDED TO
ALLOW MIXTURE TO REACH CARBURETOR.
STORE EDGER IN ASAFE PLACE. SEE WARN-
ING ABOVE.
Store theedger inthewheels-down,operatingposi-
tion. If the edger is stored in any otherposition, oil
fromthecrankcasecould enterthecylinder,causing
a serviceproblem.
You can keep your engine In good operating condi-
tion during storage by:
• Changing oil.
Lubricating the piston/cylinderarea. This can be
done byfirst removingthe spark plug and squirting
clean engineoilintothe sparkplughole.Thencover
the spark plug hole with a rag to absorb oil spray.
Next, rotatethe engine bypullingthe startertwo or
three times. Finally, reinstallspark plug and attach
spark plugwire.
