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
'_LWARNING: 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
,_LWARNING: 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.
STARTINGTHEENGINE
_LWARNING: You MUST make sure
the tubes are secure before using the
unit.
•Fuel engine. Move at least 10 feet (3
meters) away from the fueling site.
• Hold the unit in the starting position
as shown. Make sure the blower end
is directed away from people, ani-
mals, glass, and solid objects.

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 MIXTURE ADJUST-
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

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-
RANTY COMMENCEMENT DATE:
The warranty period begins on the
date the lawn and garden equipment
engine is purchased. LENGTH OF
COVERAGE: This warranty shall be
for a period of two years from the initial
date of purchase. WHAT IS COV-
ERED: REPAIR OR REPLACEMENT
OF PARTS. Repair or replacement of
any warranted part will be performed at
no charge to the owner at an approved
Sears servicing center. If you have any
questions regarding your warranty
rights and responsibilities, you should
contact your nearest authorized ser-
vice center or call Sears at
1-800-469-4663. WARRANTY PE-
RIOD: Any warranted part which is not
scheduled for replacement as required
maintenance, or which is scheduled
only for regular inspection to the effect
of "repair or replace as necessary"
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:
The owner shall not be charged for
diagnostic labor which leads to the de-
termination that a warranted part is de-
fective if the diagnostic work is per-
formed at an approved Sears servicing
center. CONSEQUENTIAL DAM-
AGES: Sears may be liable for dam-
ages to other engine components
caused by the failure of a warranted
part still under warranty. WHAT IS
NOT COVERED: All failures caused
by abuse, neglect, or improper mainte-
nance are not covered. ADD-ON OR
MODIFIED PARTS: The use of add-on
or modified parts can be grounds for dis-
allowing a warranty claim. Sears is not
liable to cover failures of warranted
parts caused by the use of add-on or
modified parts. HOW TO FILE A
CLAIM: If you have any questions re-
garding your warranty rights and re-
sponsibilities, you should contact your
nearest authorized service center or
