the tank to within 1/4"-1/2" from the
top to provide space for expansion
of fuel.
Always fill fuel tank outdoors and
use a funnel or spout to prevent
spilling.
Make sure to wipe up any spilled
fuel before stating the engine.
Store gasoline In a clean, approved
container and keep the cap in place
on the container.
TO STOP
ENGINE
To stop engine, move the throttle control lever to "STOP" position and remove key. Keep the key in a safe
place. The engine will not start without
the key.
TO START ENGINE

8. Push down on the starter button
until the engine starts. Do not crank
for more than 10 seconds at a time.
This electric starter is thermally protected. If overheated it will stop automatically and can be restarted
only when it has cooled to a safe
temperature (a wait of about 5 to 10
minutes is required).
9. When the engine starts, release the
starter button and move choke lever to "1/2 choke" position. When
engine runs smoothly, move choke
lever to "No Choke" Position.
10. Disconnect power cord from receptacle, first, and then from switch
box.
NOTE: Allow the engine to warm up for
several minutes before blowing snow in
temperatures below 0°F.
11, Run engine at full throttle "FAST'

not push the primer button, If the engine fails to start, follow the Cold Start
instructions.
COLD START
1, Be sure auger drive and traction
drive levers are in the disengaged

6. Pull the starter handle rapidly. Do
not allow the handle to snap back,
but allow it to rewind slowly while
keeping a firm hold on the starter
handle.
7. As the engine warms up, move
choke lever to "1/2 choke" position.
When engine runs smoothly, move
choke lever to "No Choke" Position.
NOTE: Allow the engine to warm up for

not push the primer button. Ifthe engine fails to start, follow the Cold Start
instructions.
TO START ENGINE
(recoil
starter)
Be sure that the engine has sufficient
oil. The snow thrower engine is
equipped with a recoil starter. Before
starting the engine, be certain that you
have read the following information.
F-0010SOJ
FROZEN STARTER
If the starter is frozen and will not turn
engine:
1. Pull as much rope out of the starter
as possible.

2.
Release the starter handle and let it
snap back against the starter.
If the engine still fails to start, repeat the
two previous steps until the engine
starts. Then continue with the directions for cold start.
Disconnect spark plug wire.
Do not place your hands in the
auger or discharge chute. Use s
pry bar.
SNOW THROWING
TIPS
1. For maximum snow thrower efficiency in removing snow, adjust ground
speed, NEVER the throttle. Go
slower in deep, freezing or wet
snow. Ifthe wheels slips, 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.
2. Most efficient snow throwing is accomplished when the snow is removed immediately after if falls.
3. For complete snow removal, slightly
overlap each path previously taken.
4. The snow should be discharged
down wind whenever possible.
5. For normal usage, set the skids so
that the scraper bar is 1/8" above
the skids. For extremely hardpacked snow surfaces, adjust the
skids upward so that the scraper
bar touches the ground.
6. On gravel or crushed 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. Rocks and gravel must not be
picked up and thrown by the machine.
To help prevent possible freeze-up of
recoil starter and engine controls, proceed as follows after each snow removal job.
1. With the engine running, pull the
starter rope hard with a continuous
full arm stroke three or four times.
Pulling of starter rope will produce a
loud clattering sound. This is not
harmful to the engine or starter.
2. With the engine not running, wipe all
snow and moisture from the carburetor cover in area of control levers.
Also move throttle control, choke
control, and starter handle several
times.

7.
After the snow throwing job has
been completed, allow the engine to
idle for a few minutes, which will
melt snow and accumulated ice off
the engine.
8. Clean the snow thrower thoroughly
after each use.
9. Remove ice and snow accumulation

thrower, and flush with water (if possible) to remove all salt or other
chemicals. Wipe snow thrower dry.

HOWTO REPLACE THE AUGER
SHEAR BOLT
The augers are secured to the auger shaft
with special shear bolts. These shear bolts
are designed to break and protect the machine if an object becomes lodged in the auger housing. Do not use e harder bolt as the
protection provided by the shear bolt will be
lost.

TO ADJUST OR REPLACE THE
SPARK PLUG
WARNING:
For safety and to
protect the machine, use only
original equipment shear bolts.
NOTE: This spark ignition system
meets all requirements of the Canadian
Interference-Causing
Equipment Regulations.
To replace a broken shear bolt, proceed
as follows. Extra shear bolts were provided in the assembly parts bag.
NOTE: This engine complies with all
current Australian and New Zealand
limitations regarding electromagnetic
interference.

If you have difficulty starting the snow
thrower, adjust or replace the spark
plug. Replace the spark plug is the
electrodes are pitted or burned or if the
porcelain is cracked. Follow the instructions below.
2. Disconnect the spark plug wire.
Make sure aH moving parts have
stopped.

If a torque wrench is available,
torque the plug to 18 to 23 foot

Be sure spark plug is clean and
free of foreign material. Check electrodes gap with a wire feeler gauge
and reset gap to 0.030" if necessary. See Figure 38.

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,
cigarette, etc.
NOTE: To prevent engine damage (if
snow thrower is not used for more than
30 days) follow the steps below.
SNOW
1.
To remove gasoline, run the engine
until the fuel tank is empty and the
engine stops.
2.
If you do not remove the gasoline,
use fuel stabilizer supplied with unit
or purchase Craftsman Fuel Stabilizer No. 3550. Add fuel stabilizer to
any gasoline left in the tank to minimize gum deposits and acids. If the
fuel tank is almost empty, mix stabilizer with fresh gasoline in a separate container and add some to the
fuel tank.
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. Inspect all visible moving parts for
damage, breakage and wear. Replace if necessary.
4. Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
5. Cover the bare metal parts of the
blower housing auger and the impeller 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.
4.
Change the engine oil.
5.
Lubricate the piston/cylinder area.
First, remove the spark plug and
squirt a few drops of clean engine
oil into the spark plug hole. Next,
cover the spark plug hole with a rag
to absorb oil spray. Then, pull two or
three times on the recoil starter rope
to rotate the engine. FinaLly, install
the spark plug and attach the spark
plug wire.
OTHER
t.
ENGINE
WARNING: Drain the gasoline outdoors, away from
fire or flame.
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 alcohol blended gasoline that uses ethanol or methanol (sometimes called
gasohol) attracts water. It acts on the
gasoline to form acids which damage
the engine.
Always follow the instruction on the
stabilizer container. After the stabilizer is added to the fuel tank, run
the engine at least ten minutes to
allow the mixture to reach the carburetor.

If possible, store your snow thrower
indoors and cover it to give protection from dust and dirt.
If the 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 moisture. Do not use plastic.
IMPORTANT: Never cover snow
thrower while engine and exhaust areas
are still warm.
