PLACE WIRE WHERE IT CANNOT CONTACT SPARK PLUG
TO PREVENT ACCIDENTAL STARTING WHEN SETTING-UP
TRANSPORTING, ADJUSTING OR MAKING REPAIRS.
IMPORTANT
SAFETY STANDARDS REQUIRE OPERATOR PRESENCE CONTROLS TO MINIMIZE THE
RISK OF INJURY. YOUR SNOW THROWER IS EQUIPPED WITH SUCH CONTROLS. DO NOT
ATTEMPT TO DEFEAT THE FUNCTION OF THE OPERATOR PRESENCE CONTROL UNDER
ANY CIRCUMSTANCES.
BEFORE USE
•Read the Owner's Manual carefully. Be thor-
oughly familiar with the controls and the proper
use of the snow thrower. Know how to stop the
snow thrower and disengage the controls
quickly.
•Do not operate the snow thrower without
wearing adequate winter outer garments.
Wear footwear that will improve footing on
slippery surfaces.
•Keep the area of operation clear of all persons,
particularly small children, and pets.
• Thoroughly inspect the area where the snow
thrower is to be used and remove all doormats,
sleds, boards, wires, and other foreign objects.
• Use extension cords and receptacles as
specified by the manufacturer for all snow
throwers with electric drive motors or with
factory-installed or optional starting motors.
• Use only attachments and accessories ap-
proved by the manufacturer of the snow th rower
(such as electric starter kits, etc.).
• Never operate the snow thrower without good
visibility or light. Always be sure of your footing,
and keep a firm hold on the handles. Walk;
never run.
• This snow thrower is for use on sidewalks,
driveways, and other ground level surfaces.
CAUTION should be exercised while using on
steep stoping surfaces. DO NOT USE SNOW
THROWER ON SURFACES ABOVE
GROUND LEVEL such as roofs of residences,
garages, porches or other such structures or
buildings.
• Check all bolts at frequent intervals for proper
tightness to be sure the snow thrower is in safe
working condition.
•Disengage clutch before starting the engine.
• Let engine and snow thrower adjust to outdoor
temperatures before starting to clear snow.
FUEL SAFETY
• Handle fuel with care; it is highly flammable.
• Use an approved fuel container.
• Check fuel supply before each use, allowing
space for expansion as the heat of the engine
and/or sun can cause fuel to expand.
• Fill fuel tank outdoors with extreme care. Never
fill fuel tank indoors.
• Replace fuel tank cap securely and wipe up
spilled fuel.
• Never remove fuel tank cap or add fuel to a
running engine or hot engine.
• Never store fuel or snow thrower with fuel in the
tank inside a building where fumes may reach
an open flame or spark.
OPERATING SAFETY
• Never allow children or young teenagers to
operate the snow thrower and keep them away
while it is operating. Never allow adults to
operate the snow thrower without proper in-
struction. Do not carry passengers.
• Always wear safety glasses or eye shields
during operation or white performing an
adjustment or repair to protect eyes from for-
eign objects that may be thrown from the snow
thrower.
• Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay
alert for hidden hazards or traffic.
• Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at
all times.
• Exercise caution to avoid slipping or falling,
especially when operating in reverse or back-
ing up.
• Do not clear snow across the face of slopes.
Exercise caution when changing direction on
slopes. Do not attempt to clear steep slopes.
• Never operate the snow thrower without
proper guards, plates or other safety protective
devices in place.
SAFETY RULES
• Never operate the snow thrower near glass
enclosures, automobiles, window wells drop-
offs, and the like without proper adjustment of
the snow discharge angle. Keep children and
pets away.
• Never operate the snow thrower at high
transport speeds on slippery surfaces. Look
behind and use care when backing.
• Never direct discharge at bystanders or allow
anyone in front of the snow thrower.
• Do not run the engine indoors, except when
starting the engine and for transporting the
snow thrower in or out of the building. Open
the outside doors; exhaust fumes are dangerous
(containing CARBON MONOXIDE, an
ODORLESS and DEADLY GAS).
• Take all possible precautions when leaving the
snow thrower unattended. Disengage the auger/
impeller, stop engine, and remove key.
•Do not overload the machine capacity by
attempting to clear snow at too fast a rate.
SAFE STORAGE
• Always refer to Owner's Manual instructions
for important details if the snow thrower is to be
stored for an extended period.
• Disengage power to the auger/impeller when
snow thrower is transported or not in use.
• Never store the snow thrower with fuel in the
fuel tank inside a building where ignition sources
are present such as hot water and space
heaters, clothes dryers, and the like. Allow the
engine to cool before storing in any enclosure.
REPAIR/ADJUSTMENTS SAFETY
• After striking a foreign object, stop the engine
and remove the wire from the spark plug, or
disconnect the cord from electric motor.
Thoroughly inspect the snow thrower for any
damage, and repair the damage before
restarting and operating the snow thrower.
• If the snow thrower should start to vibrate
abnormally, stop the engine (or electric motor)
and check immediately for the cause. Vibration
is generally a warning of trouble.
•Stop the engine (or electric motor) whenever
you leave the operating position, before un-
clogging the auger/impeller housing or dis-
charge guide, and when making any repairs,
adjustments, or inspections. Remove wire from
spark plug or disconnect cord from electric
motor.
• When cleaning, repairing, or inspecting, make
certain the auger/impeller and all moving parts
have stopped. Disconnect the spark plug wire
and keep the wire away from the plug to prevent
accidental starting.
• Never attempt to make any adjustments while
the engine is running (except when specifically
recommended in this manual).
• Maintain or replace safety and instruction
labels, as necessary.
• Run the snow thrower a few minutes after
throwing snow to prevent freeze-up of the
auger/impeller.

• MOVE THROTTLE LEVER TO STOP POSI-
TION.
•REMOVE (DO NOT TURN) IGNITION KEY.
•DISCONNECT SPARK PLUG WIRE.
• DO NOT PLACE YOUR HANDS IN THE
AUGER OR DISCHARGE CHUTE. USE A
PRY BAR.
For maximum snow thrower efficiency in removing
snow, adjust ground speed, never the throttle. Go
slower in deep, freezing, or wet snow. If the wheels,
reduce forward speed. The engine is designed to
deliver maximum performance at full throttle and
should be run at this power setting at all times.
• Most efficient snow blowing is accomplished when the
snow is removed immediately after it falls.
• For complete snow removal, slightly overlap each
path previously taken.
• The snow shouldbe discharged down wind whenever
possible.
For normal usage, set the skids so that the scraper bar
is 1/8" above the skids. For extremely hard-packed
snow surfaces, adjust the skids upward so that the
scraper bar touches the ground.
On gravel orcrushed rock surfaces, set the skids at 1-
1/4" below the scraper bar (see To Adjust Skid
Height paragraph in the Service & Adjustments
section of this manual). Stones and gravel must not
be picked up and thrown by the machine.
• Ifthe front of the snow thrower has a tendency to raise.
reduce the ground speed and engage the weight
transfer system.
• After the snow blowing job has been completed, allow
the engine to idle for a few minutes, which will melt
snow and accumulated ice off the engine.
• Clean the snow thrower thoroughly after each use.
Remove ice and snow accumulation and all debris
from the entire snow thrower, and flush with water (if
possible) to remove all salt or other chemicals. Wipe
snow thrower dry.

TO ADJUST SKID HEIGHT
This snow thrower is equipped withtwo heightadjustment
skids, located on the outside of the auger housing (See
FIG. 1). These skidselevate the frontof the snowthrower.
For normal hard surfaces such as a paved driveway or
walk, adjust the skids as follows:
•Check tire pressure (14 to 17 pounds). See side of
tire for maximum inflation. Do not exceed maximum
pressure on side of tire.
•Place the extra shear bolts supplied (found in parts
bag) under each end of the scraper bar near but not
under the skid.
• Loosen the skid mounting nuts (See FIG. 1) and
adjust the skids up to bring the front of the snow
thrower down. Re-tighten the mounting nuts.
• Set the skid on the other side at the same height.
For rocky or uneven surfaces, adjust the skids as follows:
• Raise the front of the snow thrower by moving the
skids down. This will help prevent rocks and other
debris from being picked up and thrown by the auger.
NOTE: Be sure that snow thrower is set at same height on
both sides.
TO ADJUST SCRAPER BAR
After considerable use, the metal scraper bar will have
adefinite wear pattern. The scraper bar in conjunction with
the skids should always be adjusted to allow 1/8" between
the scraper bar and the sidewalk or area to be cleaned.
• Position the snow thrower on a level surface.
• Loosen the carriage bolts and nuts securing the
scraper bar to the auger housing.

TO REPLACE AUGER SHEAR BOLT
The augers are secured to the auger shaft with special
bolts (See FIG. 16) that are designed to break (to protect
the mechlne) if an object becomes lodged in the auger
housing. Use of a harder bolt will destroy the protection
provided by the shear bolt.
IMPORTANT: TO INSURE SAFETY AND PERFOR-
MANCE LEVELS, ONLY ORIGINAL
EQUIPMENT SHEAR B O L T S
SHOULD BE USED. WHEN REPLAC-
ING SHEAR BOLTS, BE SURE TO
REPLACE SHEAR BOLT SPACERS.

TO replace a broken shear bolt, proceed as follows:
•Move the throttle to STOP and tum off all controls.
•Disconnect the spark plug wire. Be sure all moving
parts have stopped.
•Remove the broken shear bolt.
•Lubricate the auger shaft zerk fitting (See the
Customer Responsibilities section in this manual).

shaft.Installthe new shear bolt and shear bolt spacer
provided.
•Reconnect the spark plug wire.
TO ADJUST CARBURETOR
The carburetor (See FIG. 17 and (FIG. 1 Storage) has
been pre-set at the factoryand readjustment should not be
necessary. However, if the carburetor does need to be
adjusted, proceed as follows:
• Close the high speed adjusting screw by hand.
• Do not over-tighten.
• Then open it 1-1/4 to 1-1/2 turns.
• Close the idle adjusting screw byturning clockwise by
hand. Do not over-tighten.
• Then open it 1-1/4 to 1-1/2 turns.
• Start the engine and let it warm up.
• Set the throttle controlto RUN. Adjust the high speed
adjusting screw in until the engine speed or sound
alters. Adjust the screw out until the engine speed
sound alters. Note the difference between the two
limits and set the screw in the middle of the range.
• Set the throttle control to SLOW. Adjust the idle
adjusting screw in until the engine speed drops, then
adjust the screw out until the engine speed drops.
Note the difference between the two limits and set the
screw in the middle of the range.
• If the engine tends to stall under load or not accelerate
from low speed to high speed prope fly, adjust the high
speed screw out in 1/8 turn increments until the
problem is resolved.

if the porcelain is cracked.
TO ADJUST:
• Clean the spark plugby carefully scraping electrodes
(do not sand blast or use a wire brush).
•Be sure the spark plug is clean and free of foreign
matedal. Check electrodes gap (See FIG. 18) with a
wire feeler gauge and reset the gap to .030 inch if
necessary.
TO REPLACE:
•If you need a new spark plug, use only the proper
replacement spark plug (See page 4).
•Set the gap to .030.
•Before installingthe spark plug, coat itsthreads lightly
with oil or grease to insure easy removal.
•Tighten the plug firmly into the engine.

• Thoroughlyclean the snow thrower.
•Lubricate all lubrication points (See the Customer
Responsibilities section in this manual).
•Be sure that all nuts, bolts and screws are securely
fastened. Inspect allvisiblemovingparts for damage,
breakage and wear. Replace if necessary.
•Touch up all rusted or chipped paint surfaces; sand
lightlybefore painting.
• Cover the bare metal parts of the blower housing
auger andthe impellerwith rustpreventative, such as
aspray lubricant.
NOTE: Ayeady checkup or tune-up by a SEARS Service
Center is a goodway to insurethat you rsnow throwerwill
provide maximum performance for the next season.
ENGINE STORAGE
Gasoline must be removed or treated to prevent gum
deposits from forming in the tank, filter, hose, and
carburetor during storage. Also during storage, al-
cohol blended gasoline that uses ethanol or metha-
nol (sometimes called gaso hol) attracts water. It acts
on the gasoline to form acids which damage the
engine.
•To remove gasoline, run the engine until the tank is
empty and the engine stops. Then drain remaining
gasoline from carburetor by pressing upward on bowl
drain located on the bottom of carburetor (See FIG. 1).
Ifyou do not want to remove gasoline, a fuel stabilizer
(Such as Craftsman Fuel Stabilizer No. 33500) may
be added to any gasoline left in the tank to minimize
gum deposits and acids. It the tank is almost empty,
mix stabilizer with fresh gasoline in a separate con-
tainer and add some to the tank. ALWAYS FOLLOW
INSTRUCTIONS ON STABILIZER CONTAINER.
THEN RUN ENGINE AT LEAST 10 MINUTES AF-
TER STABILIZER IS ADDED TO ALLOW MIXTU R E
TO REACH CARBURETOR. STORE SNOW
THROWER IN ASAFE PLACE. SEE WARNING
ABOVE.
YOU can keep your engine In good operating condi-
tion during storage by:
• ChRngingoil (See Custiomer Responsibilities sec-
tion in this manual).
• Lubricatingthe piston/cylinder area. This can be done
by first removing the spark plug and squirting a few
drops of clean engine oil into the spark plug hole. Then
coverthe spark plug hole with a rag to absorb oil spray.
Next, rotate the engine by pulling the starter rope fully
out two orthreetimes. Finally, reinstall spark plug and
attach spark plug wire.
OTHER
• Ifpossible, store your snow thrower indoors and cover
it to give protection from dust and dirt
• Ifthe machine must be stored outdoors, block up the
snow thrower to be sure the entire machine is off the
ground.
• Cover the snow thrower with a suitable protective
cover that does not retain moistu re. Do not use plastic
IMPORTANT: NEVER COVER SNOW THROWER
WHILE ENGINE AND EXHAUST
AREAS ARE STILL WARM.
