FILL/ADD OIL:

This Edger/Trimmer was shipped with a 20

ounce container of SAE30 motor oil This

oit must be added to the engine before

operating, Remove the oil fiI_cap and fill

the crankcase,, DO NOT OVERFILL,

NOTE: Engine may already containsome

residualoil Check frequentlywhen filling

the crankcase.

OIL RECOMMENDATIONS

Only use highquality detergent oil rated

with API service classificationSG, Select

the oil's SAE viscosity grade according to

your expected operating temperature

Although multi*viscosity oils (5W30, t0W30,

etc_)improve starting incold weather, these

multi-viscosity oiJswiliresult in increased oil

consumption when used above 32°F.

Check your engine oil level more frequently

to avoid possible engine damage from

runninglow on oil,

FILL GAS

Fill the fue! 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.

L_ CAUTION: Never fillthe gas tank

while the engine is runningor hot

Immediately wipe off any spilledgasoline

before attemptingto start the engine,,

/_ CAUTION: Gasoline isflammable

and caution must be used when handlingor

storingit. Do notfill fuel tankwhile Edger/

Trimmer is running, hot,or when inan

enclosed area, Keep away from open

flame, electricalspark, and do not smoke

while filling the fuel tank Never fillfuel tank

completely; but fillthe tank to within 1/4-1/2

inchfrom the top to provide space for

expansion of fuel Always fill fuel tank

outdoorsand 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 acool, 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 itout of their reach

because the fumes are dangerous to inhale,

as wel! as being explosive°

WARNING: Experience indicates

that alcohol blended fuels called gasohol or

using methanol can attract moisture which

leads to separation and formation Ofacids

duringstorage. Acidic gas can damage the

fuel system of _n engine while instorage

To avoid engine problems;the fuel system

should be emptied before storage of 30

days or longer. Drain fuel tank, start engine

and let _trun untilfuel lines and carburetor

are empty Use fresh fuel next season. See

Storage Instructions for additional informa-

tion. Never use engine or carburetor

cleaner productsin the fuel tank or perma-

nent damage may occur°

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/

Trimmer is equipped with a recoil starter.

The operation of the engine is controlled by

the throttle control lever

• Pull the clutch lever all the way back or

up to the rearmost hole to raise and

disengage the bladeo

• Move the throttle control lever, see figure

on page 7 to the FAST position

• Push primer buttonfive times, see figure

on page 7. Wait about two seconds

between each push

NOTE: Do not use primer button to

restart a warm engine after a short

shutdown

• 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 starter

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

controllever up to increase speed; down

to decrease speed Run at full engine

speed during normal use°

NOTE: The cuttingblade speed is

controlled by the engine speed_To

reduce the cuttingblade speed, push

down on the throttle control lever To

increase the blade speed, push the

throttle control lever up

, To stopthe engine, make sure the clutch

lever isal! the way back or up and move

the+throttle control lever to the STOP

position.

CAUTION: Never run the engine

indoorsor in a poorly ventilated area°

Engine exhaust containscarbon monoxide,

an odorless and deadly gas,,Keep hands,

feet, hairand looseclothing away from any

moving partson the engine or edger/

trimmer. Avotd the muffler and surrounding

areas°Temperatures may exceed 150° F.

EDGING TIPS

• Edging is best p+erformedwhen conditions

are dry. If the soilJstowet, dirt becomes

packed in and around the blade causing

premature belt wear and decreased

performance°

• tfdid does become packed around the

blade, stop the engine, remove the spark

plug wire, and remove the packed debris

before continuingto edge°

• tfvery deep edging isrequired, we

recommend that ashallow cut be made

first,then cuts at greater depth until the

desired depth is obtalned.

• Uniform edging can be performed when

the blade guide rides on and against the

surface whtch you are edging.

• Edging can be customized by varying the

number of passes and by the distance

your blade isfrom the surface you are

edging°

• Close the high speed adjusting screw by

hand.

Do not over4ighten,

Then open it 1-1/4 to 1-1/2 turns.

Start the engine and let it warm up.

Set the throttlecontrolto 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,

ff the engine tends to stall under load or

not accelerate from low speed to high

speed properly, adjust the h_ghspeed

screw out fn 1/8 turn increments untit the

problemis resolved.

Let the engine run undisturbedfor 30

seconds between each setting to allow

the engine to reactto the previous

adjustments.

IMPORTANT: Never tamper the engine

governor, whichisfactory set for proper

engine speed. Overspeeding the engine

above the factory high speed setting can

be dangerous, ifyou think the engine-

governed high speed needs adjusting,

contact your nearest Sears Seryice

Center, which as the proper equipment

and experience to make any necessary

EDGER/TRIMMER

, Clean the Edger/Trimmer thoroughly;

remove all debris and wipe the unit dry_

• Inspect the EdgerfFrirnmer for worn or

damaged parts and tighten alt loose

hardware.

• Oil all pointsdescribed inthe Lubrication

paragraph in the Maintenance section of

this manual.

. Store the EdgerTtrimmer in a protected

area and cover for additional protec-

tion°

IMPORTANT: A yearly checkup or tune-

up by a Sears Service Center is a good

way of ensuringthat your edger/

trimmer will provide maximumpeffor-

mance for the next season.

ENGINE

IMPORTANT: Itis importantto prevent

prevent gum deposits from forming in

essential fuel systemparts suchas.the

carburetor, fuel filter,fuel hose, or tank

during storage. Also, experience indicates

that alcohol-blended fuels called gasohol or

using ethanol or methanol can attract

moisture which leadsto separation and

formation of acids during storage..Acidic

gas can damage the fuel system of an

engine while in storage.

To prevent engine damage (ff edger/

trimmer is not used for more than 30 days)

follow the steps on next page.

• To remove gasoline, runthe engine

until the tank is empty and the engine

stops.

o 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 isalmost empty,

mix stabilizer with fresh gasoline in a

separate container and add some tothe

tank. Always follow instructions on

stabilizer container. Then run engine at

least 10 minutes after stabilizer isadded

to allow mixture to reach carburetor.

Store Edger/Trimmer in a safe place. See

IMPORTANT under STORAGE (EN-

GINE).

Store the EdgerTrimmer in the wheels-

down, operating position,+Ifthe Edged

Trimmer is storedin anyother position, oi!

fromthe crankcase could enter the

cylinder, causing a service problem,,

You can keep your engine ingood operating

condition duringstorage by:

• Changing oil.

• Lubricating the piston/cylinder area

This can be done by first removing the

spark plug and squirting dean engine

oil intothe 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, reinstallspark plug and attach
