deposits from forming In the tank, fitter, hose, and

carburetor during storage. Also during storage, al-

cohol blended gasoline that uses ethanol or metha-

nol (sometimes called gasohol) attracts water. It acts
on the gasoline to form acids which damage the
engine.

o To remove gasoline, run the engine until the tank is

empty and the engine stops.

• If you do not want to remove gasoline, a fuel

stabilizer (such as Sears Craftsman fuel stabilizer

No..33500) may be added to any gasoline Iett inthe
tank to minimize gum deposits and acids_Ifthe tank
is almost empty, mix stablilizer with fresh gasoline

in a separate container and add some to the tank.
ALWAYS FOLLOW INSTRUCTIOHS ON STABI-

LIZER CONTAINER. THEN RUN ENGINE AT

LEAST 10 MINUTES AFTER STABILIZER IS
ADDED TO ALLOW MIXTURE TO REACH CAR-

BURETOR. STORE EDGER IN A SAFE PLACE.
SEE WARNING ABOVE.

You can keep your engine In good operating condi-

tion during storage by:

• Changing oil.

• Lubricating the piston/cylinder area. This can be

done by first removing the spark plug and squirting
clean engine oil into the spark plug hole Then cover

the spark plug hQtewith a rag to absorb oil spray_

Next, rotate the engine by pullingthe starter two or
three times_ Finally, reinstall spark plug and attach
spark plug wire_

EDGER STORAGE

Clean lhe edger thoroughly; remove all debris and

wipe the unit dry.

Inspect the edger for worn or damaged parts and

tighten all loose hardware

Oil all points described in the Lubrication para-

graph in the Maintenance section of this manual

Store the edger in a protected area and cover for
additional protection

IMPORTANT:

A YEARLY CHECKUP OR TUNEUP BY
A SEARS SERVICE CENTER tS A
GOOD WAY OF INSURING THAT
YOUR EDGER WILL PROVIDE

MAXIMUM PERFORMANCE FOR

THE NEXT SEASON.

f

L

• Store the edger in the wheels-down, operating
position. If the edger is stored in any other position,
oil from the crankcase could enter the cylinder,
causing a service problem_
