SAFETY RULES

CAUTION: ALWAYS DISCONNECT SPARK PLUG WIRE AND A

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

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 danger-

ous (containing CARBON MONOXIDE, an

ODORLESS and DEADLY GAS),.

eTake all possible precautions when leaving the

snow thrower unattended° Disengage the auger/

impeller, stop engine, and remove key.

eDo not overload the machine capacity by

attempting to clear snow at too fast a rate..

SAFE STORAGE

eAlways refer to Owner's Manual instructions for

important details if the snow thrower is to be

stored for an extended period.

snow thrower is transported or not in use.

Q 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 likeo A!low the

engine to cool before storing in any enclosure.r

REPAIR/ADJUSTMENTS SAFETY

e After striking a foreign object, stop the engine

and remove the wire from the spark plug, or

disconnect the cord from the 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 awarning of trouble.

eStop 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.

e Never attempt to make any adjustments while

the engine is running (except when specifically

recommended in this manual).

e Maintain or replace safety and instruction

labels, as necessary.

e Run the snow thrower a few minutes after

throwing snow to prevent freeze-up of the

BEFORE STARTING ENGINE IMPORTANT: DO NOT USE OUTBOARD MOTOR

WARNING: Experience indicates that alcohol blended

fuels (called gasohol or those using ethanol or methanol)

can attract moisture which leads to separation and for-

mation of acids during storage. Acidic gas can damage

the fuel system of an engine while in storage. To avoid

engine problems, the fuel system should be emptied

before storage for30 days or longer. Start the engine and

let it run until the fuel lines and carburetor are empty, Use

the carburetor' bowl drain to empty residual gasoline from

the float chamber (See Fig_ 19)_ Use fresh fuel next

season. (See Storage Instructions on page 18 for addi-

tional information°)

Never' use engine or carburetor cleaner products in the

fuel tank or permanent damage may occur°

OILOR AUTOMOBILE OILS, SUCH AS

SAE 30 OIL, OR MULTI-VISCOSITY

OILS, SUCH AS 10W-30 OR t0W-40

O Reinstall the cap on the gasoline container and

shake container vigorously so the oil mixes with the

gasoline ,.

O Add an additional 3 U_S quads of gasoline to the

gallon container and shake the container again

The two cycle engine used on this snow thrower requires

a mixture of gasoline and oil for lubrication of the bearings

and other moving parts. The correct fuel mixture ratio is

40:1 (3.2 oz,. oil per gallon of gas - see Fuel Mixture

Chart), Gasoline and oil must be premixed in a clean

gasoline container, Always use fresh, clean, unleaded

gasoline._

OUTDOORS AND USE A FUNNEL OR SPOUT TO

PREVENT SPILLING. MAKE SURE TO WIPE UP

ANY SPILLED FUEL BEFORE STARTING ENGINE.

STORE GASOLINE IN A CLEAN, APPROVED CON-

TAINER, AND KEEP CAP IN PLACE ON CON-

TAINER. KEEP GASOLINE IN A COOL, WELL

VENTILATED PLACE, NEVER IN THE HOUSE.

NEVER BUY MORE THAN A 30 DAY SUPPLY OF

GASOLINE TO ASSURE VOLATILITY. GASOLINE

IS INTENDED TO BE USED AS A FUEL FOR

INTERNAL COMBUSTION ENGINES; THERE-

FORE, DO NOT USE GASOLINE FOR ANY OTHER

PURPOSE. SINCE MANY CHILDREN LIKE THE

SMELL OF GASOLINE, KEEP IT OUT OF THEIR

REACH BECAUSE THE FUMES ARE

DANGEROUS TO INHALE, AS WELL AS BEING

EXPLOSIVE.

TION

SNOW THROWING TiPS

@ After three pulls, repeat the priming and pulling steps

again..

@ As engine warms up and begins to operate evenly,

move choke lever slowly to OFF position, tfthe engine

falters, return to 1/2 choke until it runs smoothly, then

move to OFF position.

NOTE: Allow the engine to warm up for' a few minutes

before using the snow thrower, as the engine will not

develop lull power untilit reaches operating temperature.

@This snow throwerwill propel itself forward when the

handle is raised enough to cause the auger blades to

contact the ground

@For most efficient snow throwing, turn the discharge

chute deflector to throw snow downwind, and slightly

overlap each swath. Use more overlap in deep snow

to prevent overloading

e The distance snow will be discharged can be ad-

justed by moving the discharge chute deflectoL Raise

the deflector for more distance or lower the deflector

for less distance.

0Irlwindy conditions, lower the chute deflector to direct

discharged snow close to the ground, where it is less

likely to blow into unwanted areas,

0Keep the area to be plowed free of stones, toys and

other foreign objects Such items might be covered by

the first snow fall and picked up by the auger while

plowing.

DRY AND AVERAGE SNOW

@ Snow up to eight inch depth can be removed rapidly

by walking at a moderate rate For snow or drifts of

a greater depth, you may find it desirable to slow your

pace to allow the discharge chute to dispose of the

snow as rapidly as the auger receives the snow..

@ Plan to have the snow discharged in the direction the

wind is blowing.

WARM START

@ Move the choke to the OFF position and pull the

starter handle until the engine starts_

@ Do not prime awarm engine. Ifthe enginefailsto start,

follow the Cold Engine Start instructions above.

WET PACKED SNOW

@ Move slowly into snow of this condition.. The greater

the depth, the slower you should go..When it appears

that the wet, packed snow is causing the auger to

slow down and the chute to clog, back off and begin

a series of short jabs into the snow.These short back

and forth, 4 to 6 inch jabbing motions will "belch" the

snow from the chute°

SNOW BANKS AND DRIFTS

@In snow of greater depth than the unit, use the

"jabbling" technique described above Turn the dis-

charge chute away from the snow bank. More time

will be required to remove snow of this type than level

snow,,

To prevent engine damage (if snow thrower is nol used

for more than 30 days) follow the steps below

SNOW THROWER STORAGE

@ Thoroughly clean the snow thrower

O Lubricate all the lubrication points (see the Customer

Responsibilities section, page 13)

Q Be sure that all nuts, bolts and screws are securely

fastened. Inspect all visible moving parts for dam-

age, breakage and wear Replace if necessary.

O Touch up all rusted or chipped paint surfaces; sand

lightly before painting

@ Cover the bare metal parts of the blower housing and

auger with rust preventative, such as sprayable

lubricant

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,

alcohol blended gasoline that uses ethanol or metha-

nol (sometimes called gasohol) attracts water, it acts

on the gasoline to form acids which damage the

engine.

@ To remove gasoline,runthe engine untilthe 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 19)

O 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 If the tank is almost empty,

mix stablilizer with fresh gasoline in a separate

container and add some to the tank. ALWAYS

FOLLOW INSTRUCTIONS ON STABILIZER CON-

TAINER. THEN RUN ENGINE AT LEAST 10 MIN-

UTES AFTER STABILIZER IS ADDED TO ALLOW

MIXTURE TO REACH CARBURETOR_ STORE

SNOWTHROWER IN A SAFE PLACE. SEE WARN-

ING ABOVE.

the spark plug hole with a rag to absorb oil spray

Next, rotate the engine by pulling the starter two or

three times Finally, reinstall spark plug and attach

spark plug wire.

OTHER

O If possible, store your snow thrower indoors and

cover it to give protection from dust and dirt

snow thrower to be sure the entire machine is off the

ground

@ Cover' the snow lhrower with a suitable protective

covet that does not retain moisture Do not use

plastic or vinyl

NOTE: A yearly checkup or tuneup at a Sears Service
