RULES FOR SAFE OPERATION
DANGER
Avoid death or serious injury from rotating auger.
Keep hands, feet and clothing away.
Unclogging discharge chute is a hazardous activity.
• Never attempt to clear auger of debris or clogged snow while equipment is
engaged or engine is running. Clogged or blocked augers store energy
and can rotate unexpectedly, EVEN WITH ENGINE OFF.
• Stop engine and disconnect spark plug wire when performing maintenance
on equipment.
• Never leave the equipment unattended while engine is running. Always
disengage the auger and traction controls, stop engine, and remove keys.
• Keep children, pets, and others out of the area during operation. Children
are often attracted to the equipment. Be mindful of all persons present.
• Keep all loose clothing far away from front of snow thrower and auger.
Scarfs, mittens, dangling drawstrings, loose clothes and pants can quickly
become caught in the rotating device and dismemberment will occur. Tie
up long hair and remove jewerly.
• The snow thrower is intended to remove snow only. Do not use for other
purposes other than what is intended.
• Do not clear snow across the face of slopes. Exercise extreme caution when
changing direction on slopes. Do not attempt to clear steep slopes.
• Do not use the snow thrower on surfaces above ground level such as roofs
of residences, garages, porches or other such structures or buildings.
DANGER
Discharge chute contains rotating impeller to throw snow.
Never clear or unclog discharge chute with your hands, or
while engine is running.
Fingers can quickly become caught and traumatic
amputation or severe laceration can result.
• Unclogging the discharge chute is a hazardous activity. Clogged or
blocked augers store energy and can rotate unexpectedly.
• Never place hands in or near discharge chute.
• With engine OFF, wait for all moving parts to cease movement, then with a
stick, clear the chute. Even with engine off, parts may rotate and
dismemberment can occur.
• Clogged snow can hide other obstructions in the chute and cause damage
to the equipment, impeller or auger. Take precautions when restating the
equipment after snow removal.
DANGER
Objects can be picked up by auger and thrown from chute.
Never throw snow toward people or cars, and never allow
anyone in front of the snow thrower.
• Be aware of your enviroment while operating equipment. Running over
items such as, gravel, doormats, newspapers, toys, and rocks hidden
under snow, can all be thrown from chute or jam in the auger.
• Always be aware of the direction the snow is being thrown. Nearby
pedestrians, pets or property may be harmed by objects being thrown.
• Familiarize yourself with the area you plan to work. Mark off boundarties of
walkways and driveways to prevent property damage, or throwing objects.
• Take caution when snow throwing in unfamiliar areas. Stay alert for hidden
hazards and traffic.
• After striking a foreign object, turn engine OFF, wait for moving parts to
cease movement, and check immediately for damage. If damaged, repair
before starting and operating snow thrower.
• With engine OFF, wait for moving parts to stop and always use a stick to
clear discharge chute.
• If unit vibrates abnormally, turn engine OFF. Vibration is generally a
warning of trouble. See an authorized dealer if necessary for repairs.
WARNING

5. If necessary, add oil until the oil reaches the FULL mark
on the oil fill/cap dipstick (see Figure 15). Do not add too
much oil.
6. Tighten the fill cap/dipstick securely each time you check
the oil level.
NOTE: For extreme cold operating conditions of 0F
(−18 C) and below, use a synthetic 5W30 motor oil for
easier starting.
NOTE: S.A.E. 5W30 motor oil may be used to make
starting easier in areas where the temperature is 20 F.
(−7 C) to 0F (−18 C). Synthetic 5W30 is acceptable for
all temperatures. DO NOT mix oil with gasoline.

1. Fill the fuel tank with fresh, clean, unleaded regular, unleaded premium, or reformulated automotive gasoline
with a minimum of 85 octane along with a fuel stabilizer
(follow instructions on fuel stabilizer package). DO NOT
use leaded gasoline. We recommend that fuel stabilizer
be added to the fuel each time that gasoline is added to
the fuel tank.
NOTE: Winter grade gasoline has higher volatility to
improve starting. Be certain container is clean and
free from rust or other foreign particles. Never use
gasoline that may be stale from long periods of
storage in the container.
CAUTION: DO NOT use gasoline containing any
amount of alcohol as it can cause serious damage to
the engine or significantly reduce the performance.
WARNING: Gasoline is flammable. Always use
caution when handling or storing gasoline.
Turn engine off and let engine cool at least two
minutes before removing the gas cap. Do not add gasoline to the fuel tank while snow blower is running, hot,
or when snow blower is in an enclosed area. Keep away
from open flame, electrical sparks and DO NOT SMOKE
while filling the fuel tank. Never fill the fuel tank completely; but fill the fuel tank to within 1-1/2 inch (3.8 mm)
from the top to provide space for the expansion of the
fuel. Always fill fuel tank outdoors and use a funnel or
spout to prevent spilling. Make sure to wipe up any
spilled fuel before starting the engine.
Store gasoline in a clean, approved container, and keep
the cap in place on the container. Keep gasoline in a
cool well ventilated place; never in the house. Never
buy more than a 30 day supply of gasoline to assure
volatility. Gasoline Is intended to be used as a fuel for
internal combustion engines; therefore, do not use
gasoline for any other purpose. Since many children
like the smell of gasoline, keep it out of their reach because the fumes are dangerous to inhale, as well as being explosive.

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. Repeat until the engine starts.
Warm engines will cause condensation in cold weather. To
help prevent possible freeze-up of recoil starter and engine
controls, proceed as follows after each snow removal job.
1. With engine off, allow engine to cool for several minutes.
2. Pull starter rope very slowly until resistance is felt, then
stop. Allow the starter rope to recoil. Repeat three times.
3. With the engine not running, wipe all snow and moisture
from the carburetor cover in area of control levers. Also
move choke knob and starter handle several times.
WARNING: 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.
S Engine parts, especially the muffler, become ex-
tremely hot. Severe thermal burns can occur on contact. Allow the engine to cool before touching.
S Never allow children to operate the snow thrower.
Never allow adults to operate the snow blower without proper instruction.
S Keep the area of operation clear of all persons, partic-
ularly small children and pets.
S Never leave the snow blower unattended while the
engine is running. Anyone operating the engine or
equipment must carefully read and understand the

OPERATING TIPS
OPERATION
1. Most efficient snowblowing is accomplished when snow
is removed immediately after it falls.
2. For complete snow removal, slightly overlap each swath
previously taken.
3. Snow should be discharged downwind whenever possible.
4. For normal usage, set the skids one−eighth inch (3 mm)
below the scraper bar. For extremely hard−packed snow
surfaces, the skids may be adjusted upward to insure
cleaning efficiency.
5. On gravel or crushed rock surfaces, the skids should be
set at 1−1/4 inch (32 mm) below the scraper bar (see To
Adjust Skid Height, in the Adjustment/Repair section in
this manual). Rocks and gravel must not be picked up
and thrown by the machine.
6. After the snowblowing job has been completed, allow the
engine to idle for a few minutes, to melt snow and ice accumulated on the engine.
7. Clean the snow thrower thoroughly after each use.
8. 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.
9. Before starting snow blower, always inspect augers and
impeller for ice accumulation and/or debris, which could
result in snow blower damage.
10. Check oil level before every start. Make sure the oil is at
the FULL mark on the oil fill cap/dipstick.

ENGINE
POWER RATINGS
The power ratings for an individual engine model are initially
developed by starting with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque
Rating Procedure) (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: differences in altitude, temperature, barometric
pressure, humidity, fuel, engine lubrication, maximum
governed engine speed, individual engine to engine
variability, design of the particular piece of power equipment,
the manner in which the engine is operated, engine run-in to
reduce friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other factors.
The power ratings may also be adjusted based on
comparisons to other similar engines utilized in similar
applications, and will therefore not necessarily match the
values derived using the foregoing codes.

Check Crankcase Oil Level before starting engine and after
each 8 hours of continuous use (see Figure 23). Add the
recommended motor oil as required.
NOTE: Overfilling the engine can affect performance.
Tighten the oil fill cap securely to prevent leakage.
Change Oil every 50 hours of operation or at least once a
year, even if the snow blower is not used for fifty hours. Use
a clean, high quality detergent oil. Fill the crank case to FULL
line on dipstick (see Figure 23). Be sure original container is
marked: A.P.I. service “SF” or higher. Do not use SAE10W40
oil (as it may not provide proper lubrication). See Chart for oil
recommendations.
To Drain Oil − Position snow blower so that the oil drain plug
is lowest point on engine. When the engine is warm, remove
oil drain plug and oil fill cap and drain oil into a suitable
container (Figure 24).
Replace oil drain plug and tighten securely. Refill crank case
with the recommended motor oil.
NOTE: Oil level must be at FULL mark.

AUGER HOUSING HEIGHT ADJUSTMENT
TO ADJUST SCRAPER BAR
After considerable use, the metal scraper bar will have a
definite wear pattern. The scraper bar in conjunction with the
skids should always be adjusted to allow one−eighth of an
inch (3 mm) between the scraper bar and the sidewalk or
area to be cleaned.
To adjust the scraper bar, proceed as follows:
1. Position the snowthrower on a level surface.
2. Loosen the carriage bolts and nuts securing the scraper
bar to the auger housing.
3. Adjust the scraper bar to the proper position. Tighten the
carriage bolts and nuts, insuring that the scraper bar is
parallel with the working surface.
4. For extended operation, the scraper bar may be reversed. If the scraper bar must be replaced because of
wear, remove the carriage bolts and nuts and install a
new scraper bar.
TO ADJUST SKID HEIGHT
This snowthrower is equipped with two height adjust skids,
secured to the outside of the auger housing. These elevate
the front of the snowthrower.
When removing snow from a hard surface area such as a
paved driveway or walk, adjust the skids up to bring the front
of the snowthrower down.
When removing snow from rock or uneven construction,
raise the front of the snowthrower by moving the skids down.
This will help to prevent rocks and other debris from being
picked up and thrown by the augers.
To adjust skids, proceed as follows:
1. Place a block (equal to height from ground desired) under scraper bar near but not under skid.
2. Loosen skid mounting nuts (Figure 29) and push the skid
down until it touches the ground. Retighten mounting
nuts.
3. Set skid on other side at same height.
NOTE: Make sure that snowthrower is set at same height
on both sides.
WARNING: 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 snowthrower.

AUGER SHEAR BOLT REPLACEMENT
The augers are secured to the auger shaft with special bolts
that are designed to break if an object becomes lodged in the
auger housing. Use of a harder bolt will reduce the protection
provided by the shear bolt. To replace a broken shear bolt,
proceed as follows:
WARNING: To insure safety and performance
levels, only original replacement shear bolts
should be used.
1. Move throttle to STOP, disengage all controls, disconnect the spark plug lead wire, and insure all moving parts
have stopped.
Shear Pin
Spacer
2. Align the hole in the auger with the hole in the auger shaft.
Install new shear bolt, spacer and locknut found in the
toolbox located on the belt cover (See Figure 50).
NOTE: The spacer fits into the larger hole in the auger
tube.
TO ADJUST OR REPLACE THE SPARK PLUG
Check the spark plug every twenty−five (25) hours. Re-
place the spark plug if the electrodes are pitted or burned
or if the porcelain is cracked.
1. Clean spark plug and reset gap periodically.
2. Clean area around spark plug base before removal, to
prevent dirt from entering engine.
3. Replace spark plug if electrodes are pitted or burned or
if porcelain is cracked.
Locknut

7. Tighten plug firmly into engine. If torque wrench is available, torque plug to 18−23 ft−lbs.
.030” (0.76 mm) Gap
4. Clean spark plug by carefully scraping electrodes (do not
sandblast or use wire brush).
5. 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” (0.76 mm) if necessary. If a new spark plug
is needed, refer to Engine Repair Parts section of this
manual for proper replacement spark plug.
6. Before installing spark plug, coat threads lightly with
graphite grease to insure easy removal.

STORAGE
OFF SEASON STORAGE
WARNING: Never store the engine, with fuel in
the tank, indoors or in a poor ventilated enclo-
sure where fuel fumes could reach an open
flame, spark or pilot light as on a furnace, water heater,
clothes dryer, etc.
Handle gasoline carefully. It is highly flammable and
careless use could result In serious fire damage to your
person and /or property.
Drain fuel into approved containers outdoors, away
from open flame.
If the snowthrower is to be stored for thirty (30) days or more
at the end of the snow season, the following steps are
recommended to prepare your snowthrower for storage.
NOTE: Gasoline must be removed or treated to prevent
gum deposits from forming in the tank, filter, hose, and
carburetor during storage.
1. To remove gasoline, run engine until tank is empty and
engine stops.
If you do not want to remove the gasoline, add fuel stabilizer
to any gasoline left 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.
ALWAYS FOLLOW INSTRUCTIONS ON STABILIZER
CONTAINER. THEN RUN ENGINE AT LEAST 10 MINUTES
AFTER STABILIZER IS ADDED TO ALLOW MIXTURE TO
REACH CARBURETOR. STORE SNOWTHROWER IN
SAFE PLACE.
2. You can help keep your engine (4−cycles only) in good
operating condition by changing oil before storage.
3. Lubricating the piston/cylinder area. This can be done by
first removing the spark plug and squirting 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 two or three times. Finally, reinstall
spark plug and attach spark plug wire.
4. Thoroughly clean the snowthrower.
5. Lubricate all lubrication points (see “Lubrication“ in the
Maintenance section).
6. Insure that all nuts, bolts, and screws are securely fastened. Inspect all visible moving parts for damage,
breakage, and wear. Replace if necessary.
7. Touch up all rusted or chipped paint surfaces; sand lightly
before painting.
8. Cover the bare metal parts of the snowthrower housing
auger, and the impeller with rust preventative.
9. If possible, store your snowthrower indoors and cover it
to give protection from dust and dirt.
10. On models with folding handles, loosen the knobs that
secure the upper handle. Rotate the upper handle back.
11. If the machine must be stored outdoors, block up the snowthrower and insure the entire machine is off the
ground. Cover the snowthrower with a heavy tarpaulin.
REMOVING THE SNOWTHROWER FROM
STORAGE
When removing the snowthrower from storage, follow the
steps below.
1. Put the upper handle in the operating position, tighten the
knobs that secure the upper handle.
2. Fill the fuel tank with a fresh fuel.
3. Check the spark plug. Make sure the gap is correct. If the
spark plug is worn or damaged, replace before using.
4. Make sure all fasteners are tight.
5. Make sure all guards, shields, and covers are in place.
