using ethanol or methanol) can attract moisture which leads to separation and formation
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. 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. Use
fresh fuel next season (See Storage instructions on page 23 for additional information).
TO START
ENGINE
(Electric
Starter)
Be sure that the engine has sufficient oil.
The snow thrower engine is equipped with a
120 volt A.C. electric starter and recoil
starter. Before starting the engine, be certain that you have read the following information:
Z_ CAUTION:
This starter is equipped
with a three-wire power cord and plug
and is designed to operate on 120 volt AC
household current. It must be properly
grounded at all times to avoid the possibility
of electrical shock which may be injurious to
operator. Follow all instructions carefully as
set forth in the "To Start Engine" section,
Determine that your house wiring is a threewire grounded system. Ask a licensed eLectrician if you are not sure. If your house wire
system is not a three-wire system, do not
use this electric starter under any conditions. If your system is grounded and a
three-hole receptacle is not available at the
point your starter will normally be used, one
should be installed by a licensed electrician.
When connecting 120 volt AC power cord,
always connect the cord to the switch box
on the engine first, then plug the other end
into the three-hole grounded receptacle.
When disconnecting power cord, always
unplug the end in the three-hole grounded
receptacle first.

FROZEN RECOIL STARTER
SNOW THROWING TIPS
If the starter is frozen and will not turn
engine:
• Pull as much rope out of the starter as
possible.
• Release the starter handle and let it snap
back against the starter.
If the starter still fails to turn engine, repeat
the two previous steps until the starter engages. Then continue with the directions for
cold start.
To help prevent possible freeze-up of recoil
starter and engine controls, proceed as follows after each snow removal job.
• With the engine running, pull the starter
rope hard with a continuous full arm
stroke three or four times. Pulling of
starter rope win produce a loud clattering
sound, This is not harmful to the engine or
starter.
• 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.
• 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 slip,
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, Use more
overlap in deep snow to prevent overloading,
• The snow should be discharged down
wind whenever possible. In windy conditions, lower the chute deflector to direct
discharged snow close to the ground,
where it is less likely to blow into unwanted areas.
• 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 or crushed rock surfaces, set
the skids at 1-1/4" below the scraper bar
(See To Adjust Skids Height paragraph on
page 18). Stones and gravel must not be
picked up and thrown by the machine.
• 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.
• 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.
A_
CAUTION:
Never run engine indoors
or in enclosed, poorly ventilated areas.
Engine exhaust contains carbon monoxide,
an odorless and deadly gas. Keep hands,
feet, hair and loose clothing away from any
moving parts on engine and snow thrower.
WARNING:
Temperature of muffler and
nearby areas may exceed 150° F. Avoid
these areas.
DO NOT allow children or young teenagers
to operate or be near snow thrower while it
is operating.
Z_
CAUTION:
Do no attempt to remove
any item that may become lodged in
auger without taking the following precautions:
• Release auger drive and traction drive
levers.
• Move throttle lever to stop position.
• 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.

LUBRICATION
OIL RECOMMENDATION
• Hex Shaft and Gears - Hex shaft and
gears require no lubrication. All bearings
and bushings are lifetime lubricated and
require no maintenance.
NOTE: Any greasing or oiling of the above
components can cause contamination of
the friction wheel. If the disc drive plate or
friction wheel comes in contact with grease
or oil, damage to the friction wheel will result.
Only use high quality detergent oit rated
with AP_ service classification SG. Select
the oil's viscosity grade according to your
expected operating temperature:
NOTE: For extreme cold operating conditions of 0° and below, use a partial synthetic
0W30 motor oil for easier starting.
Should grease or oil come in contact with
the disc drive plate or friction wheel, be sure
to clean the plate and wheel thoroughly.
NOTE: For storage, the hex shaft and
gears should be wiped with 5W-30 motor oil
to prevent rusting. See second figure on
page 15.
• Auger Gear Box - The auger gear box is
lubricated at the factory and should not
require additional lubrication. If for some
reason the lubricant should leak out, or if
the auger gear box has been serviced,
add Lubriplate No. 630-AA or equivalent.
Maximum 3-1/4 ounces should be used.
Remove filler plug as seen in figure below
once a year. If grease is visible, do not
add. If grease is not visible, use a piece
of fine wire like a dipstick, to check if
there is grease in the gearbox. Add
grease if necessary. Reinstall gear box
filler.
Change the oil every twenty-five (25) hours
thereafter, and at the beginning of each
season.
• Position the snow thrower so that the oil
drain plug is at the lowest point on the
engine. Remove the oil drain plug and
the oil fill cap/dipstick. Drain the oil into a
suitable container. Oil will drain more
freely when warm.
• Replace the oil drain plug and tighten securely.
SPARK PLUG
Make sure that the spark plug is tightened securely into the engine and the
spark plug wire is attached to the spark
plug.
If a torque wrench is available, torque
plug to 18 to 23 foot pounds.
Clean the area around the spark plug
base before removal to prevent dirt from
entering the engine.
Clean the spark plug and reset the gap
periodically at .030 inch.

CAUTION:
Be certain to maintain
proper ground clearance for your particular area to be cleared. Objects such as
gravel, rocks or other debris, if struck by the
impeller, may be thrown with sufficient force
to cause personal injury, property damage
or damage to the snow thrower.
For normal hard surfaces, adjust the skids
as follows:
• Check tire pressure (14 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.
TO ADJUSTTHE
CLUTCH CONTROL
CABLES
Periodic adjustment of the cables may be
required due to normal stretch and wear on
the belts. To check for correct adjustment,
disconnect "Z" Fitting at clutch lever, move
clutch lever to the full forward position, just
contacting the plastic bumper. The control
cables are correctly adjusted when the center of the "Z" fitting is between the center
and top of the hole and there is no droop in
the cable (see figure below). If adjustment is
necessary:
• Loosen the skid mounting nuts (see figure above) 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:

it_ CAUTION:
Never store your snow
thrower indoors or in an enclosed, poody
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.
To prevent engine damage (if snow thrower
is not used for more than 30 days} follow
the steps below.
SNOW THROWER
Carburetor Bowl
STORAGE
• Thoroughly clean the snow thrower.
• Lubricate all lubrication points (see the
Maintenance section on pages 15- t 7).
• Be sure that all nuts, bolts and screws are
securely fastened, inspect all visible moving parts for damage, breakage and wear.
Replace if necessary.
• Touch up all rusted or chipped paint surfaces; sand lightly before painting.
• 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
Craftsman Service Center is a good way to
insure that your snow thrower will provide
maximum performance for the next season.
Always follow instructions on stabilizer container. Then run engine at least 10 minutes
after stabilizer is added to allow mixture to
reaCh carburetor. Store snow thrower in a
safe place. See Caution on this page.
You can keep your engine in good operating
condition during storage by:
• Changing oil (see page 17).
• Lubricating the 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
cover the spark plug hole with a rag to
absorb oil spray. Next, rotate the engine
by pulling the starter rope fully out two or
three times. Finally, reinstall spark plug
and attach spark plug wire.
ENGINE STORAGE
OTHER
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 methanol (sometimes called gasohol) 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
next figure).
• If possible, store your snow thrower indoors and cover it to give protection from
dust and dirt.
• _fthe machine must be stored outdoors,
block up the snow thrower to be sure the
entire machine is off the ground.
• Cever the snow thrower with a suitable
protective cover that does not retain
moisture. Do not use plastic or vinyl.
IMPORTANT:
Never cover snow thrower
while engine and exhaust areas are still
warm.
• If you do not want to remove gasoline, a
fuel stabilizer (such as Craftsman Fuel
Stabilizer No. 33500) may be added to
any gasoline |eh in the tank to minimize
gum deposits and acids. If the tank is almost empty, mix stabilizer with fresh gasoline in a separate container and add some
to the tank.
