CAUTION: Always disconnect spark
plug wire and place wire where it cannot
contact spark plug to prevent accidental
starting when setting-up, transporting,
adjusting or making repairs.
IMPORTANT: Safety standards require
operator presence controls to minimize the
risk of injury. Your edger is equipped with
such controls. Do not attempt to defeat the
function of the operator presence control
under any circumstances.
BEFORE

your expected operating temperature:
Fill the fuel tank with clean, fresh, unleaded
grade automotive gasoline. Be sure that
the container you pour the gasoline from is
clean and free from dust or other foreign
particles. Never use gasoline that may be
stale from long periods of storage in the

Although multi-viscosity
oils (5W30,
10W30, etc.) improve starting in cold
weather, these multi-viscosity oils will result
in increased oil consumption when used
above 32°F. Check your engine oil level
more frequently to avoid possible engine
damage from running low on oil.
TO ADD ENGINE OIL
• Place the edger on a level surface.
• Remove the oil fill cap as shown in next
figure.
• Fill the engine crankcase, pouring slowly.
Do not overfill. For approximate capacity

• Reinstall the oil fill cap and tighten
securely. Wipe away excess oil.
• Check oil before each use. Add if
needed.
• Change oil after the first 2 operating
hours and every 25 operating hours
thereafter.
WARNING:
Reinstall fuel cap.
Experience
indicates that
alcohol blended fuels (called gasohol or
using methanol) can attract moisture which
leads to separation and formation of acids
during storage. Acidic gas can damage the
fuel system of an engine while in storage.
To avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. Drain fuel tank, start engine
and let it run until fuel lines and carburetor
are empty. Use fresh fuel next season. See
Storage Instructions for additional information. Never use engine or carburetor
cleaner products in the fuel tank or permanent damage may occur.

and caution must be used when handling or
storing it. Do not fill fuel tank while Edger is
running, hot, or when Edger is in an
enclosed area. Keep away from open
flame, electrical spark, and do not smoke
while filling the fuel tank. Never fill fuel tank
completely; but fill the tank to within 1/4-1/2
inch from the top to provide space for

expansion of fuel. Always fill fuel tank
outdoors and use a funnel or spout to
prevent spilling. Make sure to wipe up any
spilled fuel before starting the engine. Store
gasoline in a clean, approved container,
and keep the cap in place on the container.
Keep gasoline in a cool, well ventilated
place; never in the house. Never buy more
than a 30 day supply of gasoline to ensure
volatility. Gasoline is intended to be used as
a fuel for internal combustion engines;
therefore, do not use gasoline for any other
purpose. Since many children like the smell
of gasoline, keep it out of their reach
because the fumes are dangerous to inhale,
as well as being explosive.

WARNING:
Never run the engine
indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide,
an odorless gas and deadly gas. Keep
hands, feet, hair and loose clothing away
from any moving parts on the engine or
edger. Avoid the muffler and surrounding
areas. Temperatures may exceed 150' F.
EDGING TIPS
• Edging is best performed when conditions
are dry. if the soil is too wet, dirt becomes
packed in and around the blade causing
premature belt wear and decreased
performance.
• If dirt does become packed around the
blade, stop the engine, remove the spark
plug wire, and remove the packed debris
before continuing to edge.
• ff very deep edging is required, we
recommend that a shallow cut be made
first, then cuts at greater depth until the
desired depth is obtained.
• Uniform edging can be performed when
the blade guide (see figure on page 6)
rides on and against the surface which
you are edging.
• Edging can be customized by varying the
number of passes and by the distance
your blade is from the surface you are
edging.

the linkage bracket and replace the
hairpin cotter in the hole in the hook.
ADJUSTMENT
• When the depth control lever is in the
forward adjustment slot, the engine
platform should be approximately level
and the edging blade tip should be 1-1/4
to 1-1/2 inches above the surface of the
ground.
• When the depth control lever is in the rear
adjustment slot the edging guide (see
figure below) should be approximately 1/4
inch above the surface which you
are edging and the blade tip should be
2-5/8 to 2-7/8 inches below the surface of
the ground. The two middle adjustment
slots provide shallower edging depths.
Lower
Rod
• To adjust the depth control lever to give
the proper blade proper blade positions,
remove the ignition wire from the spark
plug and keep the wire away from the

edger indoors or in an enclosed, poody
ventilated area. If gasoline remains in the
tank, fumes may reach an open flame,
spark or pilot light from a furnace, water
heater, clothes dryer, cigarette, etc.
• Oil all points described in the Lubrication
paragraph in the MAINTENANCE section
of this manual.
• Store the edger in a protected area and
cover for additional protection.

• Clean the edger thoroughly; remove all
debris and wipe the unit dry.
IMPORTANT:A

yearly checkup or tune-
up by a Sears Service Center is a
good way of ensuring that your Edger

the tank to minimize gum deposits
and acids. If the tank is almost empty,
mix stabilizer with fresh gasoline in a
separate container and add some to the
tank. Always follow instructions on
stabilizer container. Then run engine at
least 10 minutes after stabilizer is added
to allow mixture to reach carburetor.
Store edger in a safe place. See warning
on page 13.
ENGINE
IMPORTANT:
It is important to prevent
gum deposits from forming in essential
fuel system parts such as the carburetor,
fuel filter, fuel hose, or tank during storage.
Also, experience indicates that using
alcohol-blended fuels (called gasohol,
ethanol or methanol) can attract moisture
which leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system of an engine while
in storage.
• 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.
You can keep your engine in good operating condition during storage by:
To prevent engine damage (if edger is not
used for more than 30 days) follow the
steps below.
• 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 hole with a rag to absorb oil spray.
Next, rotate the engine by pulling the
starter two or three times. Finally,
reinstall spark plug and attach spark plug
wire.
• 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 left in
