Caution: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and forma-
tion 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 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. See
Storage section of this manual for additional infor-
mation.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
Never fill fuel tank indoors, when engine
is running or while engine is still hot.
Never fill fuel tank completely. Fill
tank to within 1/4 to 1/2 inch from the
top to provide space for expansion of
fuel. Wipe up any spilled fuel before
starting engine. Store gasoline in a
clean, approved container.

The Maintenance Check List is supplied to assist the
operator in proper maintenance of the snow thi ower.
This is only a check list; instructions for adjustments
will be found in the Adjustments/Repairs section _fthis
manual.
Some adjustments will need to be made perio{_ically
to properly maintain your snow thrower.
All adjustments in Adjustments/Repairs section _fthis
manual should be checked at least once a seaso 1.The
following should be performed more than once each
season.
All Bolts and Nuts--Should be checked often to make
certain they are tight, preferably after each us{_.
Engine and Snow Thrower--Lubricate as inst_ucted
in the following section.
LUBRICATION
Engine Lubrication--Check Oil Level before starting
engine and every 5 hours of operation. Oil level must
be maintained between the "Full" and "Add" tnarks
on dipstick. Refer to "To Service Engine" instru ;tions
on page 11.
Change Oil after first 2 hours of operation and every
25 hours thereafter. Change at least once a yea 'if the
snow thrower is not used for 25 hours.
To drain oil, position snow thrower so the oil drai 1plug
is the lowest point on the engine. Remove oil drai _ plug
and oil fill cap. See figure 23. Drain oil into a sL,itable
container. Oil will drain more freely when wart 1.
Replace oil drain plug and tighten securely. Refill
crankcase with SAE 10W30 motor oil. SAE 5W30 motor
oil may be substituted when temperature is consi ;tently
20°F. or lower.

WARNING
....... it
Never store engine with fuel in tank
indoors or in poorly ventilated
enclosures, where fumes may reach an
open flame, spark or pilot light such
as on a furnace, water heater, clothes
dryer, etc.
It is important to prevent gum deposits from f{)rming
in essential fuel system parts such as the carburetor,
fuel hose or fuel tank during storage. Also, experience
indicates that alcohol blended fuels (called gas )hol or
using ethanol or methanol) can attract moisture which
leads to separation and formation of acids during
storage. Acidic gas can damage the fuel syster i of an
engine while in storage.
14
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow
these instructions.
1. Run engine until fuel tank is empty and engine
stops due to lack of fuel.
2. Disconnect fuel line at carburetor or fuel tank. Be
careful not to damage fuel line, fittings or fuel tank.
Drain any remaining fuel from the system.
t WARN,NGt
Drain fuel into approved container
outdoors, away from open flame.
I_ NOTE
If gasohol has been used, complete the
preceding instructions. Then put a small
amount of unleaded (or regular) grade
gasoline into fuel tank and repeat steps
1 and 2.
3. Change oil if it has not been changed recently.
Refer to Maintenance section.
spark plug hole with a clean rag. Pull the starter
rope slowly to allow the piston to coat the internal
engine parts. Reinstall the spark plug. Do not con-
nect spark plug wire.
5. Thoroughly clean the snow thrower. If unit isto be
stored in an unventilated or metal storage shed,
coat any metal parts with a light oil or silicone to
prevent rust.
4. Remove the spark plug and squirt one ounce of
clean engine oil into spark plug hole. Cover the 6. Store in a clean, dry area.

before performing any
adjustments or repairs.
SKID SHOE ADJUSTMENT
The snow thrower isequipped with two adjustable skid
shoes, located on each side of the auger housing. The
skid shoes determine the distance between the scraper
bar and the ground, which varies according to the type
of surface to be cleared.
Normal, Hard Surfaces
When removing snow from a normal, hard surface such
as a paved driveway or walk, the skid shoes should be
adjusted to be approximately 1/4" lower than the
scraper bar.
To adjust, proceed as follows.
1. Make certain both tires are inflated equally (15 to
20 psi), and that neither tire is resting on a link of
the tire chains.
2. Place the threaded ends of the spare shear bolts
(provided in hardware pack) under the scraper bar,
one at each end. See figure 25.
3. Loosen the four hex nuts on the skid shoes. Push
each skid shoe up or down until it touches the
ground. Retighten the hex nuts securely.
Make certain the snow thrower is set at the same height
on both sides, and the entire bottom surface of skid
shoe is against the ground to avoid uneven wear.
Uneven or Rocky Surfaces
When removing snow from uneven, rockyor gravel sur-
faces, raise the scraper bar by moving the skid shoes
down to avoid throwing gravel. Adjust as instructed
above, using thicker objects under the scraper bar to
act as spacers.
IIBI_NOTE
Both the skid shoes and the shave
plate are subject to wear and should
be replaced when necessary.

TRACTION DRIVE CLUTCH LEVER ADJUSTMENT
Periodic adjustment of the traction drive cable may be
required due to normal wear on the friction wheel If
adjustment is necessary, unhook the spring on the end
of the traction drive cable. Refer to figure 13. Adjust
as instructed in steps 2 and 3 of "Attaching the Trac-
tion Drive Cable" in Assembly Instructions, page 8.
AUGER DRIVE CLUTCH LEVER ADJUSTMENT
The auger drive cable should be adjusted at least once
a season. To adjust the auger cable, remove the fer-
rule from the auger bracket by removing the cotter pin

hub. Then, using a 112" wrench, tighten securely.
8. Replace the bottom frame cover.
AUGER SHEAR BOLT REPLACEMENT
The augers are secured to the auger shaft with two
special shear bolts and hex lock nuts. If you hit a foreign
object or ice jam, snow thrower is designed so the bolts
will break (to protect the snow thrower). Refer to figure
25.
If the augers will not turn, check to see if the hex bolts
have sheared. Two spare bolts and hex lock nuts have
been provided with the snow thrower. Use only original
equipment shear bolts and nuts, part numbers
710-0890 (shear bolt) and 712-0429 (hex lock nut).
SPARK PLUG
Clean spark plug and reset gap periodically.Clean area
around spark plug base before removing to prevent dirt
from entering engine. Replace spark plug if electrodes
are pitted or burned, or if porcelain is cracked. Spark
plug replacement isrecommended at beginning of each
season. Refer to Engine Repair Parts section of this
manual for proper replacement plug. If reusing spark
plug, clean by carefully scraping electrodes (do not
sand blast or use wire brush). Be certain entire spark
plug is clean. Cleck electrodes gap with a wire feeler
gauge, and reset gap to 0.030 if necessary. See figure
37.
Install spark plug in engine, and tighten securely. If tor-
que wrench is available, torque plug to between 18 and
23 foot pounds.

FIGURE 37.
CARBURETOR ADJUSTMENT
If any adjustments are made to the
engine while the engine is running
(e.g., carburetor), keep clear of all
moving parts. Be careful of heated
surfaces and muffler.
The carburetor has been pre-set at the factory and
should not require adjustment. However, if the car-
buretor needs adjustment, proceed as follows. See
figure 38.
1. Close high speed adjusting screw by hand. Do not
overtighten. Then open it 1-1/4 to 1-1/2 turns.
2. Close idle adjusting screw by hand. Do not over-
tighten. Then open it 1-1/4 to 1-1/2 turns.
3. Start the engine, and allow it to warm up.
4. Set the throttle control to FAST. Adjust high speed
adjusting screw in or out until the engine runs
smoothly at full throttle. If the engine has a tenden-
cy to stall under load, open high speed adjusting
screw slightly to obtain a richer fuel mixture.
5. Set the throttle control to SLOW. Adjust idle ad-
justing screw in or out until the engine runs
smoothly at idle.
Allow the engine to run undisturbed for a few seconds
between each new setting so that the engine can react
to each setting.
WARNING_'_
Never tamper with the engine governor,
which is set at the factory for proper
engine speed. Overspeeding the engine
above factory high speed setting is
dangerous. If you think the engine
governed high speed needs adjusting,
contact your nearest SEARS Service
Center, who has the proper equipment
and experience to make any necessary
adjustments.
