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.

TO START THE ENGINE
Before starting the engine, be sure you
have read and understood all the instructions on the preceding pages. The edger/
trimmer is equipped with a recoil starter.
The operation of the engine is controlled by
the throttle control lever.

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 frOe'from dust or other foreign
particles. Never use gasoline that may be
stale from long periods of storage in the
,_ainer.

• Pull the clutch lever all the way back or
up to the rearmost hole to raise and
disengage the blade.
• Move the throttle control lever, see figure
on page 7 to the FAST position.

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.

CAUTION:

• Push primer button five times, see figure
on page 7. Wait about two seconds
between each push.

Gasoline is flammable

NOTE: Do not use primer button to
restart a warm engine after a short
shutdown.

and caution must be used when handling or
storing it. Do not fill fuel tank while edger/
trimmer is running, hot, or when 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
spilJed 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 assure
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 engine, grasp the engine starter
handle firmly with your right hand.
" Hold the edger handle firmly with your
left hand.
° Pull up sharply on the recoil stader
handle. DO NOT allow the starter rope to
snap back, let it rewind slowly while
holding the starter handle. If engine fails
to start after three pulls, push primer
button two times and pull starter rope
again.
When the engine starts. Push throttle
control lever up to increase speed; down
to decrease speed. Run at full engine
speed during normal use.

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 edgerl

EDGING TIPS
• Edging is best performed when conditions
are dry. If the soil is to 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.

The cutting blade is subject to wear and
damage such as nicks and dents. This will
not generally affect its function.
This blade is specially designed to not require sharpening. Do not attempt to sharpen
this blade. The blade is reversible. If the
nicks and dents are excessive, remove the
blade, turn it around and reinstall. This will
provide a fresh cutting edge. The blades
should be replaced if both sides are worn
and damaged.

• Set the throttle control to FAST. Adjust
the high speed adjusting screw In until
the engine speed or sound alters. Adjust
the,screw out until the engine speed
sound alters. Note the difference between
the two limits and set the screw in the
middle of the range.

CARBURETOR

The carburetor shown below has been preset at the factory and readjustment should
not be necessary. However, if the carburetor does need to be adjusted, proceed as
follows:

• If the engine tends to stall under load or
not accelerate from low speed to high
speed properly, adjust the high speed
screw out in 1/8 turn increments until the
problem is resolved.
• Let the engine run undisturbed for 30
seconds between each setting to allow
the engine to react to the previous
adjustments,

IMPORTANT:
Never tamper 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 enginegoverned high speed needs adjusting,

A yearly checkup or tune-

up by a Sears Service Center is a good
way of ensuring that your edger/
trimmer will provide maximum performance for the next season.

ENGINE

EDGER/TRIMMER

IMPORTANT:
It is important to prevent
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 alcohol-blended fuels called gaschol or
using 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.

• Clean the edger/trimmer thoroughly;
remove all debris and wipe the unit dry.
• Inspect the edger/trimmer 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 edge/trimmer in a protected
area and cover for additional protection.

To prevent engine damage (if edger/
trimmer is not used for more than 30 days)
follow the steps on next page.

• To remove gasoline, run the engine
until the tank is empty and the engine
stops.

trimmer is stored in any other position,
from the crankcase could enter the

oil

cylinder, causing a service problem.

• 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
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.

You can keep your engine in good operating
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.

Store edger/trimmer
in a safe place. See
IMPORTANT under STORAGE (ENGINE).
• Store the edger/trimmer in the wheelsdown, operating position. If the edger/
