6. Whencleaning,repairingorinspectingthesnowthrower,
stop the engine and make certain the collector/impel-
ler and all moving parts have stopped. Disconnect
the spark plug wire and keep the wire away from the
plug to prevent someone from accidentally starting the
engine.
7. 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 dangerous.
Clearing a Clogged Discharge Chute
Handcontactwiththerotatingimpellerinsidethedischarge
chute is the most common cause of injury associated with
snow throwers. Never use your hand to clean out the dis-
charge chute. To clear the chute:
1. SHUT THE ENGINE OFF!
2. Wait 10 seconds to be sure the impeller blades have
stopped rotating.
3. Always use a clean-out tool, not your hands.
8. Exercise extreme caution when operating on slopes.
Maintenance and Storage
1. Check shear bolts and other bolts at frequent intervals
for proper tightness to be sure the equipment is in safe
working condition.
2. Never store the machine with fuel in the fuel tank
inside a building where ignition sources are present
such as hot water heaters, space heaters, or clothes
dryers. Allow the engine to cool before storing in any
enclosure.
3. Always refer to operator’s manual for important details
if the snow thrower is to be stored for an extended
period.
9. Neveroperatethesnowthrowerwithoutproperguards,
and other safety protective devices in place and work-
ing.
10. Never direct the discharge toward people or areas
where property damage can occur. Keep children and
others away.
11. Do not overload the machine capacity by attempting
to clear snow at too fast a rate.
12. Never operate the machine at high transport speeds
on slippery surfaces. Look behind and use care when
operating in reverse.
13. Disengage power to the collector/impeller when snow
thrower is transported or not in use.
14. Use only attachments and accessories approved by
the manufacturer of the snow thrower (such as wheel
weights, counterweights, or cabs).
4. Maintain or replace safety and instruction labels, as
necessary.
5. Run the machine a few minutes after throwing snow
to prevent freeze-up of the collector/impeller.
15. Never operate the snow thrower without good visibility
or light. Always be sure of your footing, and keep a firm
hold on the handles. Walk; never run.
16. Never touch a hot engine or muffler.

OPERATION
TO ADJUST SKID PLATES (See Fig. 16)
WARNING: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
NOTE: The wrench provided in your parts bag may be
used to adjust the skid plates.
Skid plates are located on each side of the auger housing
and adjust the clearance between the scraper bar and the
ground surface. Adjust skid plates evenly to proper height
for current surface conditions. For removal of snow in
normal conditions, such as a paved driveway or sidewalk,
place skid plates in the highest position (lowest scraper
clearance) to give a 1/8" clearance between the scraper
bar and the ground. Use a middle position if the surface
to be cleared is uneven.
CAUTION: Alcohol blended fuels (called gaso-
hol 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 of
30 days or longer. Empty the gas tank, start
the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel next
season. SeeStorageInstructionsforadditional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.
NOTE: It is not recommended to operate the snow thrower
overgravelorrockysurfaces.Objectssuchasgravel,rocks
or other debris, can easily be picked up and thrown by the
impeller, which can cause serious personal injury, property
damage or damage to the snow thrower.
•
If snow thrower must be operated over gravel surface,
use extra caution and be sure skid plates are adjusted
to lowest (highest scraper clearance) position.

BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL (See Fig. 17)
The engine on your snow thrower has been shipped, from
the factory, already filled with oil.
1. Check engine oil with snow thrower on level ground.
2. Remove oil fill cap/dipstick and wipe clean, reinsert
the dipstick and screw tight, wait for a few seconds,
remove and read oil level. If necessary, add oil until
“FULL” mark on dipstick is reached. Do not overfill.
•
To change engine oil, see “TO CHANGE ENGINE OIL”
in the Maintenance section of this manual.
ADD GASOLINE (See Fig. 17)
•
Fill fuel tank to bottom of tank filler neck. Do not over-
fill. Use fresh, clean, regular unleaded gasoline with
a minimum of 87 octane. Do not mix oil with gasoline.
Purchase fuel in quantities that can be used within 30
days to assure fuel freshness.

OPERATION
TO START ENGINE
Be sure fuel shut-off valve is in the “OPEN” position.
5. Pull recoil starter handle quickly. Do not allow starter
rope to snap back.
•
6. Whentheenginestarts,releasetherecoilstarterhandle
and slowly move the choke control to the “OFF” posi-
tion.
Your snow thrower engine is equipped with both a 120 Volt
A.C. electric starter and a recoil starter. The electric starter
is equipped with a three-wire power cord and plug and is
designed to operate on 120 Volt A.C. household current.
Allow the engine to warm up for a few minutes. Engine will
not develop full power until it has reached normal operat-
ing temperature.
•
Be sure your house is a 120 Volt A.C. three-wire
grounded system. If you are uncertain, consult a
licensed electrician.
WARM START - RECOIL STARTER
Follow the steps above, keeping the choke in the “OFF”
position. DO NOT push the primer.
WARNING: Do not use the electric
starter if your house is not a 120 Volt
A.C.three-wiregroundedsystem. Seri-
ous personal injury or damage to your
snow thrower could result.
BEFORE STOPPING
Run the engine for a few minutes to help dry off any mois-
ture on the engine.
IF RECOIL STARTER HAS FROZEN
COLD START - ELECTRIC STARTER
If the recoil starter has frozen and will not turn the engine,
proceed as follows:
1. Grasp the recoil starter handle and slowly pull as much
rope out of the starter as possible.
2. Release the recoil starter handle and let it snap back
against the starter.
1. Insert safety ignition key (packed separately in parts
bag)intoignitionslotuntilitclicks. DONOTturnthekey.
Keep the extra safety ignition key in a safe place.
2. Place ON / OFF switch in “ON” position.

this time the snow is usually dry and has not been ex-
posed to the direct sun and warming temperatures.
8. Disconnect the power cord from the receptacle first,
then from the engine.
•
Slightly overlap each successive path to ensure all
snow will be removed.
Allow the engine to warm up for a few minutes. Engine will
not develop full power until it has reached normal operat-
ing temperature.
•
•
Throw snow downwind whenever possible.
Adjust the skid plates to proper height for current snow
conditions. See “TO ADJUST SKID PLATES” in this
section of this manual.
WARM START - ELECTRIC STARTER
Follow the steps above, keeping the choke control in the
“OFF” position.

CARBURETOR
Your carburetor is not adjustable. Engine performance
should not be affected at altitudes up to 7,000 feet (2,134
meters). If your engine does not operate properly due to
suspected carburetor problems, take your snow thrower
to a qualified service center.
ENGINE SPEED
Never tamper with the engine governor, which is factory set
for proper engine speed. Overspeeding the engine above
the factory high speed setting can be dangerous and will
void the warranty. If you think the engine-governed high
speed needs adjusting, contact a qualified service center,
which has proper equipment and experience to make any
necessary adjustments.

the end of the season or if the unit will not be used for 30
days or more.
Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
Use fresh fuel next season.
WARNING: Never store the snow

NOTE: Fuel stabilizer is an acceptable alternative in mini-
mizing the formation of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer container.
Run engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburetor. Do not empty
the gas tank and carburetor if using fuel stabilizer.
SNOW THROWER
When snow thrower is to be stored for a period of time,
clean it thoroughly, remove all dirt, grease, leaves, etc.
Store in a clean, dry area.
1. Clean entire snow thrower (See “CLEANING” in the
Maintenance section of this manual).
ENGINE OIL
Drain oil (with engine warm) and replace with clean engine
oil. (See “ENGINE” in the Maintenance section of this
manual).
CYLINDER
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through spark plug hole
into cylinder.
3. Pullrecoilstarterhandleslowlyafewtimestodistribute

OTHER
•
•
•
Remove safety ignition key; store it in a safe place.
Do not store gasoline from one season to another.
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
ENGINE
See engine manual.
•
•
If possible, store your snow thrower indoors and cover
it to protect it from dust and dirt.
Cover your snow thrower with a suitable protective
cover that does not retain moisture. Do not use plastic.
Plastic cannot breathe, which allows condensation to
form and will cause your snow thrower to rust.
FUEL SYSTEM
IMPORTANT: It is important to prevent gum deposits from
forming in essential fuel system parts such as carburetor,
fuel hose, or tank during storage. Also, alcohol blended
fuels (called gasohol or 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.
IMPORTANT: Never cover snow thrower while engine/
exhaust area is still warm.
