the safety rules, do not attempt to fuel

your unit. Call the 1-800 number listed

on the front of this manual,

FUELING ENGINE

This engine is certified to operate on

unleaded gasoline, Before operation,

gasotine must be mixed with a good

quality 2-cycle air-cooled engine oil.

We recommend Craftsman brand oil,

Mix gasoline and oil at a ratio of 40:1

(A 40:1 ratio is obtained by mixing 3.2

ounces of oil with 1 gallon of unleaded

gasoline). DONOT USEautomotive oil

or boat oil. These oils will cause

engine damage. When mixing fuel,

follow instructions printed on container.

Once oil is added to gasoline, shake

container momentarily to assure that

the fuet isthoroughly mixed. Always

read and follow the safety rules

relating to fuel before fueling your unit.

IMPORTANT

Experience indicates that alcohol

blended fuels (called gasohol or using

ethanol or methanol) can attract mois-

ture which leads to separation and

formation of acids during storage.

Acidic gas can damage the fuel sys-

tem of an engine while in storage.

To avoid engine problems, empty fuel

system before storage for 30 days or

longer.Drain gas tank,start engine and

let it run untilfuei linesand carburetor

are empty. Use fresh fuel next season.

Never use engine or carburetor clean-

er products in the fue! tank or perma-

nent damage may occur.

OPERATING INSTRUCTIONS

OPERATING POSITION

ALWAYS WEAR: _ Eye Protection

Long Pants

Heavy Shoes

Cut from your right your left.

Do not run the engine at a higher speed

than necessary. The cutting line wilt cut

efficiently when the engine is run at less

than full throttle. At lower speeds, there

is less engine noise and vibration. The

cutting line will last longer and will be

less likelyto "welc£ onto the spool,

Always release the throttle trigger and

allow the engine to return to idle speed

when not cuffing.

To stop engine:

° Release the throttle trigger.

° Push and hold the engine stop

switch in the STOP or OFF position

until the engine has fully stopped.

TWIST-N-EDGE

• Pull the tab toward the engine.

• Twist the tube to the edging position;

release tab.

TRIMMER LINE ADVANCE

proper length.

Always tap the trimmer head on a

grassy area. Tapping on surfaces such

as concrete or asphalt can cause ex-

cessive wear to the trimmer head.

Ifline is worn dov_ to 2 in, (5 cm) or

less, more than one tap will be required

to obtain the most efficient line length.

WARNING: Use only .080" (2 ram)

diameter line. Other sizes of line wil!

not advance properly and can cause

serious injury'. Do not use other materi-

als such as wire, string, rope, etc, Wire

can break off during cutting and be-

come a dangerous missile that can

cause serious injury.

CUTTING METHODS

WARNING: Use minimum speed and

do not crowd the line when cutting

around hard objects (rock, gravel,

fence posts, etc.), which can damage

the trimmer head, become entangled

in the fine, or be thrown causing a seri-

ous hazard.

• The tip of the line does the cutting.

You will achieve the best perform-

ance and minimum line wear by not

crowding the line into the cutting

area. The right and wrong ways are

shown below.

Tipof the Line I Line Crowded Into

DoesThe Cutting I WorkArea

Right " _a_t Wrong " "'

• The fine will easily remove grass and

weeds from around walls, fences,

trees and flower beds, but it also can

cut the tender bark of trees or shrubs

and scar fences. To help avoid dam-

age especially to delicate vegetation

or trees with tender bark, shorten line

to 4--5 in. (10-13 cm) and use at less

than full throttle,

• For trimming or scalping, use less

than full throttle to increase fine life

and decrease head wear, especially:

• During light duty cutting.

• Near objects around which the line

can wrap such as small posts,

trees or fence wire.

• For mowing or sweeping, use full

throttle for a good clean job.

WARNING: Always wear eye protec-

tion. Never tean over the trimmer head.

Rocks or debris can ricochet or be

thrown into eyes and face and cause

blindness or other serious injury.

TRIMMING - Hold the bottom of the

trimmer head about 3 in. (8 cm) above

the ground and at an angle. Allow only

the tip of the line to make contact. Do

not force trimmer tine into work area.

SCALPING - The scalping technique

removes unwanted vegetation. Hold

the bottom of the trimmer head about 3

in. (8 cm) above the ground and at an

angle. Allow the tip of the line to strike

the ground around trees, posts, monu-

ments, etc. This technique increases

line wear.

MOWING - Your trimmer isideal for

mowing in places conventional lawn

mowers cannot reach, in the mowing

position, keep the line parallel to the

ground. Avoid pressing the head into

the ground as this can scalp the

ground and damage the tool.

SWEEPING - The fanning action of

rotating line can be used for a quick

and easy clean up. Keep line parallei

to and above the surfaces being swept

and move the tool from side to side.

EDGING - The Twist-N-Edge feature

allows for easy edging of sidewalks,

patios, driveways, etc. Adjust trimmer

to the edging position. Allow only the

tip of the line to make contact. Do not

force trimmer line into work area.

CARBURETOR ADJUSTMENT

WARNING: The trimmer head will be

spinning during most of this procedure.

Wear your protective equipment and

observe all safety precautions. After

making mixture adjustments, recheck

idle speed.

Carburetor adiustment is critical and if

done improperly can permanently

damage the engine as well as the car-

buretor. If you require further assis-

tance or are unsure about performing

this procedure, call our customer as-

sistance help line at 1-800-235-5878.

Old fuel, a dirty air filter,a dirty fuel fil-

ter, or flooding may give the impres-

sion of an improperly adjusted carbu-

retor. Check these conditions before

adjusting the carburetor.

The carburetor has been carefully set

at the factory. Adjustments may be

necessary if you notice any of the fol-

lowing conditions:

• Engine will not idle. See "Idle Speed"

under adjusting procedure.

• Engine dies or hesitates instead of

accelerating. See "Acceleration

Check" under adjusting procedure.

• Loss of cutting power. See "Mixture

Adjustment" under adjusting

procedure,

There are two adjustment screws on

the carburetor. They are located in the
