HOW TO REMOVE OBJECTS
FROM AUGER
_ ARNING: Do not attempt
auger with your hands. Use a pry
bar to remove snow or debris.
to remove snow or debris
that may become lodged in
• Release auger drive lever.
• Move the stop switch to the stop
position to stop the engine.
• Disconnect spark plug wire.
• Do not place your hands in the au-
ger or discharge chute. Use a pry
bar to remove snow or debris.
SNOW THROWING TIPS
1. When the handle is raised, the au-
ger blades will engage the ground
and the snow thrower will move for-
ward. When the auger drive lever is
released, the auger blades will stop.
If the blades do not stop, see "How
To Adjust The Auger Drive Cable" in
the Service And Adjustment section.
2. Most efficient snow throwing is ac-
complished when the snow is re-
moved immediately after if falls.
3. For complete snow removal, slightly
overlap each previous path.
4. Whenever possible, discharge the
snow down wind.
5. The distance the snow will be dis-
charged can be adjusted by moving
the discharge chute deflector. Raise
the deflector for more distance or
lower the deflector for less distance.
6. In windy conditions, lower the chute
deflector to direct the discharged
snow close to the ground where it is
less likely to blow into unwanted
areas.
7. For safety and to prevent damage
to the snow thrower, keep the area
to be cleared free of stones, toys
and other foreign objects.
8. When clearing snow from crushed
rock or gravel driveways, do not al-
low the auger blades to contact the
driveway. Move the handle down to
slightly raise the auger blades.
9. The forward speed of the snow
thrower is dependent on the depth
and weight of the snow. Experience
will establish the most effective
method of using the snow thrower
under different conditions.
F 0410670
10. After each snow throwing job, allow
the engine to run for a few minutes.
The snow and accumulated ice will
melt off the engine.
11. Clean the snow thrower after each
use.
12. Remove ice, snow and debris from
the entire snow thrower. Flush with
water to remove all salt or other
chemicals. Wipe snow thrower dry.
DRY AND AVERAGE SNOW
1. Snow up to eight inches deep can
be removed rapidly and easily by
walking at a moderate rate. For
snow or drifts of a greater depth,
slow your pace to allow the dis-
charge chute to dispose of the snow
as rapidly as the auger receives the
snow.
2. Plan to have the snow discharged in
the direction the wind is blowing.
WET PACKED SNOW
Move slowly into wet, packed snow. If
the wet, packed snow causes the auger
to slow down or the discharge chute be-
gins to clog, back off and begin a series
of short back and forth jabs into the
snow. These short back and forth jabs,
four to six inches, wil! "belch" the snow
from the chute.
SNOW BANKS AND DRIFTS
In snow of greater depth than the unit,
use the same "jabbing" technique de-
scribed above. Turn the discharge
chute away from the snow bank. More
time wil! be required to remove snow of
this type than level snow.

POWER RATINGS
The power ratings for an individual
engine model are initially developed by
starting with SAE (Society of Automo-
tive Engineers) code J1940 (Small
Engine Power & Torque Rating Proce-
dure) (Revision 2002-05). Given both
the wide array of products on which our
engines are placed, and the variety of
environmental issues applicable to
operating the equipment, it may be that
the engine you have purchased will not
develop the rated horsepower when
used in a piece of power equipment
(actual "on-site" power). This difference
is due to a variety of factors including,
but not limited to, the following: differ-

,_ WARNING: Never store your
snow thrower with gasoline
in the fuel tank indoors or in
an enclosed, poorly ventilated area.
If gasoline remains in the tank,
fumes may reach an open flame,
spark or pilot light from a furnace,
water heater, clothes dryer, ciga-
rette, etc.
To prevent damage (if snow thrower is
not used for more than 30 days) follow
the steps below.
SNOW THROWER
1. Thoroughly clean the snow thrower.
2. Lubricate all lubrication points. See
the Maintenance section.
3. Be sure that all nuts, bolts and
screws are securely fastened. In-
spect all visible moving parts for
damage, breakage and wear. Re-
place if necessary.
4. Touch up all rusted or chipped paint
surfaces; sand lightly before paint-
ing.
5. Cover the bare metal parts of the
blower housing auger and the im-
peller with rust preventative, such
as a spray lubricant.
NOTE: A yearly checkup or tune-up by
a Sears service center is a good way of
ensuring that your snow thrower will
provide maximum performance for the
next season.
ENGINE
Gasoline must be removed or treated to
prevent gum deposits from forming in
the fuel tank, filter, hose, and carburetor
during storage. Also, during storage al-
cohol blended gasoline that uses etha-
nol or methanol (sometimes called
gasohol) attracts water. It acts on the
gasoline to form acids which damage
the engine.
1. Run the engine until the fuel tank is
empty and the engine stops.
F 041067C
If you do not remove the gasoline,
use fuel stabilizer supplied with unit
or purchase Craftsman Fuel Stabi-
lizer No. 3550. Add fuel stabilizer to
any gasoline left in the tank to mini-
mize gum deposits and acids. If the
fuel tank is almost empty, mix stabi-
lizer with fresh gasoline in a sepa-
rate container and add some to the
fuel tank.
Always follow the instructions on the
stabilizer container. After the stabi-
lizer is added to the fuel tank, run
the engine at least ten minutes to
allow the mixture to reach the car-
buretor.
4.
While the engine oil is warm,
change the engine oil.
5.
Remove the spark plug and pour
about 15 ml (1/2 oz) of engine oil
into the cylinder. Replace the spark
plug and crank slowly to distribute
the oi!.
,_ WARNING: Do not crank en-
gine with spark plug re-
moved.
6. Store in a clean and dry area, but
NOT near a stove, furnace or water
heater which uses a pilot light or
any device that can create a spark.
OTHER
1. If possible, store your snow thrower
indoors and cover it to give protec-
tion from dust and dirt.
2. If the snow thrower must be stored
outdoors, put the snow thrower on
blocks to raise it off of the ground.
3. Cover the snow thrower with a suit-
able protective cover that does not
retain moisture. Do not use plastic.
IMPORTANT: Never cover snow
thrower while engine and exhaust areas
are stil! warm.
