SAFETY NOTICE: Exposure to vibra-
tions through prolonged use of gaso-
line powered hand tools could cause
blood vessel or nerve damage in the
fingers, hands, and joints of people
prone to circulation disorders or ab-
normal swellings. Prolonged use in

cold weather has been linked to blood
vessel damage in otherwise healthy

people. If symptoms occur such as
numbness, pain, loss of strength,
change in skin color or texture, or loss
of feeling in the fingers, hands, or

joints, discontinue the use of this tool
and seek medical attention. An anti-

vibration system does not guarantee
the avoidance of these problems.

Users who operate power tools on a

continual and regular basis must mon-

itor closely their physical condition and

the condition of this tool.

SPECIAL NOTICE: This unit is

equipped with a temperature limiting

muffler and spark arresting screen
which meets the requirements of Cali-
fornia Codes 4442 and 4443. All U.S.

forest land and the states of California,

Idaho. Maine, Minnesota, New Jersey,
Oregon, and Washington require by

law that many internal combustion en-
pines be equipped with a spark arrest-

ng screen. If you operate in a locale

where such regulations exist, you are

legally responsible for maintaining the
operating condition of these parts.

Failure to do so is a violation of the

law. For normal homeowner use, the

muffler and spark arresting screen will

not require any service. After 50

hours of use, we recommend that your

muffler be serviced or replaced by
your Sears Service Center.

FUELING ENGINE

_ WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on

unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality synthetic 2-cycle air-cooled
engine oil.

5

WerecommendCraftsmanbrand
syntheticoil.Mixgasolineandoilat a

ratio of 40:1. A 40:1 ratio is obtained
by mixing 3.2 ounces of oil with 1

gallon of unleaded gasoline. Included
with this trimmer is a 3.2 ounce

container of oil. Pour the entire
contents of this container into 1 gallon

of gasoline to achieve the proper fuel
mixture. DO NOT USE automotive 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 fuel is thoroughly 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 system of an
engine while in storage. To avoid en-
gine problems, empty the fuel system
before storage for 30 days or longer.

Drain the gas tank, start the engine and
let it run until the fuel lines and carbure-

tor are empty. Use fresh fuel next sea-
son. Never use engine or carburetor

cleaner productsin the fuel tank or per-
manent damage may occur.

See the STORAGEsection for additional
information.

OPERATINGINSTRUCTIONS
Itisrecommended that the engine

not be operated for longer than 1
minute at full throttle.

OPERATING POSITION

ALWAYSWEAR:_ _ Eye

Long Pants .,_b.li_

Heavy Shoes.._._ / _._,_

Cut from your left to your right.

_WARNING: Always wear eye
protection. Never lean over the trimmer

head. Rocks or debris can ricochet or
be thrown into eyes and face and

cause blindness or other serious injury.
When operating unit, stand as shown

and check for the following:
* Wear eye protection and heavy

clothing.

. Hold trigger handle with right hand

and assist handle with left hand.
. Keep unit below waist level.
. Cut only from your left to your right to

ensure debris is thrown away from

you. Without bending over, keep line

near and parallel to the ground and

not crowded into material being cut.

Do not run the engine at a higher
speed than necessary. The cutting
line will 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 likely to "weld"
onto the spool.

Always release the throttle trigger and
allow the engine to return to idle
speed when not cutting.

To stop engine:
. Release the throttle trigger.

. Move the ON/OFF switch to the OFF

position.
TWIST AND EDGE
The Twist and Edge feature allows for

easy edging of sidewalks, patios,
driveways, etc.

1. Pull the tab toward the engine.

Protection

i

2. Twist the tube to the edging posi-
tion; release tab.

TRIMMER LINE ADVANCE
The cutting head advances line au-

tomatically. Do not tap head on the

bground to advance line. This may

reak parts and cause cutting head to

malfunction.
Upon unit start up, the line will advance

automatically to the correct cutting path

length.

Always keep the shield in place when
the tool is being operated.

_WARNING: Use only 0.080

inch (2 mm) diameter round line.
Other sizes and shapes of line will not
advance properly and will result in im-

proper cutting head function or can
cause serious injury. Do not use other

materials such as wire, string, rope,
etc. Wire can break off during cutting
and become 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 line, or be thrown
causing a serious 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.

• The line 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 damage especially to delicate
vegetation or trees with tender bark,

SCALPING - The scalping technique
removes unwanted vegetation down
to the ground. Hold the bottom of the
trimmer head about 3 inches (8 cm)
above the ground and at an angle. Al-
low the tip of the line to strike the
ground around trees, posts, monu-
ments, etc. This technique increases

line wear.

SWEEPING - The fanning action of
the rotating line can be used for a
quick and easy clean up. Keep the

line parallel to and above the surfaces
being swept and move the tool from

side to side.

Sweeping

EDGING - Adjust trimmer to the edg-
ing position (see TWIST AND EDGE

section). Allow only the tip of the line
to make contact. Do not force trimmer

line into work area.

MOWING - Your trimmer is ideal 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.
