Fuel Fill Cap
FILL GAS:
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
container. Reinstall fuel cap.
WARNING:
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.
,/_ WARNING:
Gasoline is flammable
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 moi'e
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 t O
inhale, as well as being explosive.,
.
TO START THE ENGINE
Before starting the engine, be Su/'e you
have read and understood all the instructions on the preceding pages. The edger is
equipped with a recoil starter. The operation of the engine is controlled by the
throttle control lever. See page 6.
• Push the depth control lever forward and
latch in the forward slot of the adjustment
bracket to raise the blade.
• Move the throttle control lever, see figure
on page 6, to the FAST '_
position.
• Push primer button I_" five times, see
figure on page 6. Wait about two
seconds between each push.
NOTE: Do not use primer to restart a
warm engine after a short shutdown.
• Pull the engine control lever back to
contact the upper handle tube and hold
the edger handle and control lever firmly
with your left hand.
• To start engine, grasp the engine starter
hanclle firmly with your right hand.
• Pull back sharply on the recoil starter
handle. DO NOT allow the starter rope to
snap back. let it rewind slowly while
NOTE: If engine fails to start after three
pulls, push primer button two times and
pull starter rope again.
• When the engine starts, run at full engine
speed during normal use.
NOTE: The cutting blade speed is
controlled by the engine speed. To
reduce the cutting blade speed, push
back on the throttle control lever. To
increase the blade speed, push the
throttle controt lever forward.
To stop O
the engine, make sure the
depth control lever is all the way forward
and release the engine control lever to
the stop position or pu==sh
the throttle
control lever to stop _1.
See figure on
page 6.
Z_ 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.
If 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

platform should be approximately level
and the edging blade tip should be 1-1/4
to t-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 middt e adjustment
slots provide shallower edging depths.

CARBURETOR
ADJUSTMENT
The carburetor has been pre-set at the
factory and readjustment should not be
necessary. However, if the carburetor does
need to be adjusted, contact your nearest
Craftsman Service Center.
IMPORTANT:
Never tamper with the
engine governor, which is factory set for
proper engine speed. Overspeeding the
engine above the factory high speed
setting can be dangerous. If you think the
engine-governed high speed needs
adjusting, contact your nearest Craftsman
Service Center, which has the proper
equipment and experience to make any
necessary adjustments.
WARNING:
Is added to allow mixture to reach
carburetor. Store Edger in a safe place.
See warning on this page.

Edger indoors or in an enclosed, poorly
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.
• Store the Edger in the wheels-down,

IMPORTANT:
It is important to prevent
gum deposits from forming in essential
fuel system parts such as the carburetor,
fuet fitter, 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 engiri_ whil'e
in storage.
To prevent engine damage (if Edger is not
used for more than 30 days) follow the
steps below.
• 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 Craftsman fuel
stabilizer No. 33500) may be added to
any gasoline left in 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
