SAFETY NOTICE: Exposure to vibra-

tions through prolonged use of gasoline

powered hand tools could cause blood

vessel or nerve damage in the fingers,

hands, and joints of people prone to cir-

culation disorders or abnormal swell-

ings. Prolonged use in cold weather

has been linked to blood vessel dam-

age 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 atten-

tion. An anti-vibration system does not

guarantee the avoidance of these prob-

lems. Users who operate power tools

on a continual and regular basis must

monitor 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 engines

be equipped with a spark arresting

screen. If you operate in a locale where

such regulations exist, you are legally

responsible for maintaining the operat-

ing condition of these parts. Failure to

do so is a violation of the law. For nor-

mal homeowner use, the muffler and

spark arresting screen will not require

any service. After 50 hours of use, we

recommend that your muffler be ser-

viced or replaced by a Sears Service

Center=

OIL CAPACITY

The engine holds approximately 3

ounces of oil. Use only high quality

detergent oil rated with API service

classification SJ-SL. Select the oil's

SAE viscosity grade according to your

expected operating temperature. For

most applications, SAE-80 oil is rec-

ommended. Do not use special addi-

tives.

_:.,,,_>. NOTE: Synthetic oil meet-

ing ILSAO GF-2, API certifi-

_ cation mark and API ser-vice symbol (shown at left)

with "SJ/CF ENERGY CON-

SERVING" or higher, is an

acceptable oil at all temper-

atures. Use of synthetic

oil does not alter required

oil change intervals.

SAE Viscosity Grades

S-ARI _G IEMPERATUR_ R_,_GE ANT ClPA El} B FOI_E _,FXT OIL CHANG_

CAUTION: Air cooled engines run

hotter than automotive engines. The

use of non-synthetic multi-viscosity

oils (5W30, 10W30, etc.) in tempera-

tures above 40"F (4"C) will result in

higher than normal oil consumption.

When using a multi-viscosity oil,

check oil level more frequently to

avoid possible engine damage from

running low on oil.

*CAUTION: Synthetic oil must be

used when operating engine under

40"F (4"C) or engine damage will oc-

cur.

**CAUTION: SAE 30 oil, if used be-

low 50°F (10°C), will result in hard

starting and possible engine damage

due to inadequate lubrication.

ADD OIL

Your trimmer is shipped without oil in

the engine. The engine holds approxi-

mately 3 fluid ounces (90 ml) of oil

when at the FULL mark on the oil dip-

stick. Included with this trimmer is a 3.4

ounce (90 ml) container of SAE 30 SJ-

SL oil for properly filling the engine with

oil for first time use only. Pour the entire

contents of this 3.4 ounce container of

oil into the oil fill spout.

NOTE: The dipstick will show slightly

above FULL. This is acceptable for

first time use only as the engine

breaks in. After the first time oil fill, sim-

ply refill the engine with oil to the FULL

mark on the dipstick as needed.

CAUTION: DO NOT overfill engine with

oil or it will smoke on start-up.

CAUTION: KEEP ENGINE LEVEL

---- r ------ ....

Engine must be level, with oil fill facing

up, to check oil. If engine is not level,

dipstick reading will not be accurate.

This will lead to possible over or under

filling causing damage to the engine.

Check oil level before starting the en-

gine.

• Check oil level before every use.

• Keep oil level at FULL.

• DO NOT overfill. Use a measure cup for

filling.

• Add only 1 ounce--0.5 ounce at a time.

7. If needed, add 0.5 ounce of oil at a

time and recheck the dipstick until

oil reaches the FULL level.

8. Always be sure to retighten oil dip-

stick before starting engine.

Check oil level before each use. Add

oil if needed. Fill to FULL line on dip-

stick. Change oil after first 4 hours of

use, then every 8 hours of operation

or each season (see CHANGE ENGINE

OIL in the MAINTENANCE section).

Change oil every 4 hours when oper-

ating the engine under heavy load or

in high temperatures. You may need

to change the oil more often under

dusty, dirty conditions.

ADD GASOLINE

Use fresh, clean, regular unleaded gas-

oline with a minimum of 87 octane. Do

not mix oil with gasoline. Purchase

fuel in quantities that can be used within

30 days to assure fuel freshness.

IMPORTANT

Alcohol blended fuels (called gaeohol

or using ethanol or methanol) can at-

tract moisture which leads to separa-

tion and formation of acids during stor-

age. Acidic gas can damage the fuel

system of an engine while in storage.

To avoid engine 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 carburetor are empty. Use fresh

fuel next season.

Never use engine or carburetor cleaner

products in the fuel tank or permanent

damage may occur.

See the STORAGE section for additional

information.

_WARNING: Fill to bottom of gas

tank filler neck. DO NOT overfill. Wipe

off any spilled fuel. Do not store, spill

or use gasoline near an open flame.

,AI_WARNING: Allow engine to cool

for 2 minutes before removing fuel cap

for refueling. Remove fuel cap slowly.

1. Tilt engine in angle shown to prop-

erly fill fuel tank.

_&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.

• Hold unit so that engine is below

waist level.

• Cut only from your right to your left 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

DoesTheCuttingWorkArea

Right Wrong

• 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.

• For trimming or scalping, use less

than full throttle to increase line 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.

TRIMMING - Hold the bottom of the

trimmer head about 3 inches (8 cm)

above the ground and at an angle. Al-

low only the tip of the line to make

contact with vegetation. Do not force

trimmer line into work area.

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.

5. Replace engine oil fill cap/dipstick.

Tighten securely.

CLEAN AIR FILTER

A dirty air filter decreases engine per-

formance and increases fuel con-

sumption and harmful emissions. Al-

ways clean after every 8 hours of

operation. Clean more often under

dusty conditions or when airborne de-

bris is present. Replace air cleaner

parts if very dirty.

1. Clean the cover and the area

around it to keep dirt from falling

Cover

INSPECT MUFFLER AND SPARK

ARRESTING SCREEN

As the unit is used, carbon deposits

build up on the muffler and spark ar-

resting screen. For normal homeown-

er use, however, the muffler and spark

arresting screen will not require any

service. After 50 hours of use, we rec-

ommend that your muffler and spark

arresting screen be serviced or re-

placed by a Sears Service Center.

REPLACE SPARK PLUG

Replace the spark plug each year to

ensure the engine starts easier and

runs better. Set spark plug gap at

0.025 inch. Ignition timing is fixed and

nonadjustable.

1. Twist, then pull off spark plug boot.

2. Remove spark plug from cylinder

and discard.

3. Replace with Champion RDJ-7Y

spark plug and tighten securely with

a 5/8 inch socket wrench.

4. Reinstall the spark plug boot.

CALIFORNIA AND UNITED STATES

EMISSION CONTROL DEFECTS

WARRANTY STATEMENT: The U.S.

Environmental Protection Agency/Cali-

fornia Air Resources Board and Sears,

Roebuck and Co., U.S.A., are pleased

to explain the emissions control system

warranty on your year 2000 and later

small off-road engine (SORE). In Cali-

fornia, all new small off-road engines

must be designed, built, and equipped

to meet the State's stringent anti-smog

standards. Elsewhere in the United

States, new non-road, spark-ignition

engines certified for model year 1997

and later, must meet similar standards

set forth by the U.S. EPA. Sears must

warrant the emission control system for

the periods of time listed below provided

there has been no abuse, neglect, or

improper maintenance of your small off-

road engine engine. Your emission con-

trol system includes parts such as the

carburetor, air cleaner, ignition system,

muffler and catalytic converter. Also in-

cluded may be connectors and other

emissions-related assemblies. Where a

warrantable condition exists, Sears will

repair your small off-road engine en-

gine at no cost to you. Expenses cov-

ered under warranty include diagnosis,

parts and labor. MANUFACTURER'S

EMISSION CONTROL DEFECTS

WARRANTY COVERAGE: Small off-

road engines are warranted relative to

emission control parts defects for a peri-

od of two years, subject to these provi-

sions. If any covered part on your en-

gine is defective, the part will be

Sears Engine Warranty Policy.

Sears is not liable to cover failures

of Warranted Parts caused by the

use of add-on, non-original, or

modified parts.

5. Maintenance

Any Warranted Part which is not

scheduled for replacement as re-

quired maintenance or which is

scheduled only for regular inspec-

tion to the effect of "repair or re-

place as necessary" shall be war-

ranted as to defects for the

warranty period. Any Warranted

Part which is scheduled for re-

placement as required mainte-

nance shall be warranted as to de-

fects only for the period of time up

to the first scheduled replacement

LOOK FOR RELEVANT EMISSIONS DURABILITY PERIOD AND AIR INDEX

INFORMATION ON YOUR ENGINE EMISSIONS LABEL

Engines that are certified to meet the

California Air Resources Board

(CARB) Tier 2 Emissions Standards

must display information regarding the

Emissions Durability Period and Air

index. Sears makes this information

available to the consumer on our

emission labels and hang tags.

The Emissions Durability Period de-

scribes the number of hours of actual

running time for which the engine is

certified to be emissions compliant,

assuming proper maintenance in ac-

cordance with the operating and main-

tenance instructions. The following

categories are used:

Moderate: Engine is certified to be

emission compliant for 50 hours of ac-

tual engine running time.

Intermediate: Engine is certified to

be emission compliant for 125 hours

of actual engine running time.

Extended: Engine is certified to be

emission compliant for 300 hours of

actual engine running time.

For example, a typical consumer

string trimmer is used 5 to 10 hours

per year. Therefore, the Emissions

Durability Period of an engine with

an moderate rating would equate to 5

to 6 years.

The Air Index is a calculated number

describing the relative level of emis-

sions for specific engine family. The

lower the Air Index, the cleaner the

engine. This information is displayed

in graphical form on the emissions la-

bel or hang tag.

AFTER JULY 1, 2000, LOOK FOR

EMISSIONS COMPLIANCE PERIOD

ON ENGINE EMISSIONS COM-

PLIANCE LABEL

After July 1, 2000, certain Craftsman

engines will be certified to meet the

United States Environmental Protec-

tion Agency (U.S. EPA) Phase 2 Class

IV emissions standards. For Phase 2

Class IV certified engines, the Emis-

sions Compliance Period referred to

on the emissions compliance label in-

dicates the number of operating hours

for which the engine has been shown

to meet federal emission require-

ments. For engines equal to or great-

er than 20 cc, and less than 50 cc dis-

placement, Category C = 50 hours, B

= 125 hours, and A = 300 hours.

The displacement of Model Series

21000 engines is 34 cc, 21100 en-

gines is 40 cc.

This is a generic represen-

tation of the emissions

compliance label typically

found on a certified engine:

This engine is certified to be emissions compliant for the following use:

[] Moderate (50 hours)

[] Intermediate (125 hours)

[] Extended (300 hours)
