FILL/ADD OIL:

This Edger was shipped with a 20 ounce

container of SAE30 motor oil. This oil must
be added to the engine before operating.

Remove the oil fill cap and fill the crank-

case to 1/4 inch from top of oil fill hole,

residual oil remaining. DO NOT OVERFILL.

OIL RECOMMENDATIONS

Only use high quality detergent oil rated
with API service classification SG. Select

the oil's SAE viscosity grade according to
your expected operating temperature:

Co_der << _ >>Warmer

<< _ -- >>

5W30 SAE30

NOTE: 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 see PRODUCT SPECIFICA-

TIONS on page 10 of this manual,

• Reinstall the oil fill cap and tighten

securely, Wipe away excess oil,

• Check oil before each use, Add if

needed.

• Change oil every 25 operating hours

thereafter,

CAUTION: Never fill the gas

tank

while the engine is running or hot.

Immediately wipe off any spilled gasoline
before attempting to start the engine.

Oil Fill Cap

D_Fuel Fill Cap

FILL GAS:

NOTICE: ENGINES WHICH ARE CERTI-
FIED TO COMPLY WITH CALIFORNIA

AND US EPA EMISSION REGULATIONS
FOR ULGE ENGINES: Are certified to

operate on regular unleaded gasoline.

Include the following emission control

system(s): EM, TWC (if so equipped).

Include any user adjustables features -

therefore no other adjustments are needed.

Fill the fuel tank with clean, fresh, unleaded
premium or reformulated automotive

gasoline only. DO NOT use leaded
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.

Z_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 informa-

tion. Never use engine or carburetor
cleaner products in the fuel tank or perma-

nent 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 _ling 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.

TO START THE ENGINE

Before starting the engine, be sure you
have read and understood all the instruc-

tions on the preceding pages. The Edger is
equipped with a recoil starter. The opera-

tion 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

handle firmly with your right hand.

• Pull back sharply on the recoil starter

handle. DO NOT allow the starter rope to

I/

snap back, let it rewind slowly while

holding the starter handle.

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 fu!l 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 control lever forward.

• To stop I_ 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=shthe throttle
control lever to stop IO. See figure on

page 6.

,_ WARNING: Never run the engine

indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide,

an odorless 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. Tem-
peratures 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 for
location) 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.

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.

_k

WARNING: Never store your

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.

EDGER

• Clean the 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

paragraph in the MAINTENANCE section
of this manual.

• Store the Edger in a protected area and
cover for additional protection.

IMPORTANT:A yearly checkup or tune-
up by a Craftsman Service Center is a

good way of ensuring that your Edger
will provide maximum performance for

the next season.

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.

To prevent engine damage (if Edger is not
used for more than 30 days) follow the

steps on next column.

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.

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 instruc-
tions 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 this page.

• 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 operat-
ing condition 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 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.
