OPERATING TIPS
While vacuuming or blowing debris,
hold the unit with the muffler side fac- ing away from your body and clothes
(see OPERATING POSITION).
To reduce the risk of hearing loss
associated with sound level(s), hear- ing protection is required.
To reduce the risk of injury associated
with contacting rotating parts, stop the engine before installing or removing
attachments. Do not operate without guard(s) in place.
Operate power equipment only at rea-
sonable hours-not early in the morn- ing or late at night when people might
be disturbed. Comply with times listed in local ordinances. Usual recommen-
dations are 9:00 a.m. to 5:00 p.m., Monday though Saturday.
To reduce noise levels, limit the num-
ber of pieces of equipment used at any one time.
To reduce noise levels, operate pow-
er blowers at the lowest possible throttle speed to do the job.
Use rakes and brooms to loosen
debris before blowing.
In dusty conditions, slightly dampen
surfaces or use a mister attachment when water is available.
Conserve water by using power blow-
ers instead of hoses for many lawn and garden applications, including
areas such as gutters, screens, patios, grills, porches, and gardens.
Watch out for children, pets, open
windows, or freshly washed cars. Blow debris away safely.
Use the full blower nozzle extension
so the air stream can work close to the ground.
After using blowers and other equip-
ment, CLEAN UP! Dispose of debris in trash receptacles.

BEFORE STARTING ENGINE
_WARNING: Be sure to read the fuel information in the safety rules
before you begin. If you do not understand the safety rules, do not
attempt to fuel your unit. Call 1-800-235-5878.
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 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). DO NOT USE automotive oil
or boat oil. These oils will cause en- gine 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 relat- ing 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 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 clean-
er products in the fuel tank or perma-
nent damage may occur.
Fuel stabilizer is an acceptable alter-
native in minimizing the formation of fuel gum deposits during storage.
Craftsman brand oil is already blended with fuel stabilizer. See the STORAGE
section for additional information.
STOPPING YOUR ENGINE
To stop the engine, move the throttle lever to the STOP position.

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 LOW SPEED
MIXTURE ADJUSTMENT (L) under ad- justing procedure.
Engine dies or hesitates instead of ac-
celerating. See ACCELERATION CHECK under adjusting procedure.
Loss of power. See MIXTUREADJUST-
MENT (L or H) under adjusting proce- dure.
There are two adjustment screws on the carburetor. The low speed adjust- ment screw is marked with the letter L,
and the high speed adjustment screw is marked with the letter H. The throttle
lever is used to control engine speed. The throttle lever can be placed in one
of four positions: STOP, IDLE or "_1_, FULLTHROTTLE or '_, and one inter- mittent position.

MANUFACTURER'S WARRANTY COVERAGE: If any emissions related
part on your engine (as listed under
Emissions Control Warranty Parts List)
is defective or a defect in the materials or workmanship of the engine causes
the failure of such an emission related part, the part will be repaired or re-
placed by Sears. OWNER'S WAR-
RANTY RESPONSIBILITIES: As the
lawn and garden equipment engine owner, you are responsible for the per-
formance of the required maintenance listed in your instruction manual. Sears recommends that you retain all re-
ceipts covering maintenance on your lawn and garden equipment engine,
but Sears cannot deny warranty solely for the lack of receipts or for your fail- ure to ensure the performance of all
scheduled maintenance. As the lawn and garden equipment engine owner,
you should be aware that Sears may deny you warranty coverage if your
lawn and garden equipment engine or a part of it has failed due to abuse, ne-
glect, improper maintenance, unap- proved modifications, or the use of
parts not made or approved by the original equipment manufacturer. You
are responsible for presenting your lawn and garden equipment engine to
a Sears authorized repair center as soon as a problem exists. Warranty repairs should be completed in a rea-
sonable amount of time, not to exceed 30 days. If you have any questions
regarding your warranty rights and re- sponsibilities, you should contact your
nearest authorized service center or call Sears at 1-800-469-4663 WAR-

rights and responsibilities, you should contact your nearest authorized set-
vice center or call Sears at

shall be warranted for 2 years. Any
warranted part which is scheduled for
replacement as required maintenance
shall be warranted for the period of time up to the first scheduled replace-
ment point for that part. DIAGNOSIS:

diagnostic labor which leads to the de-
termination that a warranted part is de- fective if the diagnostic work is per-

ages to other engine components caused by the failure of a warranted part still under warranty. WHAT IS

modified parts. HOW TO FILE A CLAIM: If you have any questions re-
garding your warranty rights and re-
sponsibilities, you should contact your
