• Read this operator's manual carefully in its entirety
before attempting to assemble or operate this
machine. Be completely familiar with the controls
and the proper use of this machine before
operating it. Keep this manual in a safe place for
future and regular reference and for ordering
replacement parts.
• Never allow children under 14 years old to operate
a snow thrower. Children 14 years old and over
should only operate snow thrower under close
parental supervision. Only persons well acquainted
with these rules of safe operation should be
allowed to use your snow thrower.
• No one should operate this unit while intoxicated or
while taking medication that impairs the senses or
reactions.
• Keep the area of operation clear of all persons,
especially small children and pets.
• Exercise caution to avoid slipping or falling,
especially when operating in reverse.
2. PREPARATION
• Thoroughly inspect the area where the equipment
is to be used and remove all door mats, sleds,
boards, wires and other foreign objects.
• Disengage all clutches and shift into neutral before
starting engine.
• Do not operate equipment without wearing
adequate winter outer garments. Do not wear
jewelry, long scarfs or other loose clothing which
could become entangled in moving parts. Wear
footwear which will improve footing on slippery
surfaces.
• Before working with gasoline, extinguish all
cigarettes and other sources of ignition. Check the
fuel before starting the engine. Gasoline is an
extremely flammable fuel. Do not fill the gasoline
tank indoors, while the engine is running, or until
engine has been allowed to cool at least two
minutes. Replace gasoline cap securely and wipe
off any spilled gasoline before starting the engine
as it may cause a fire or explosion.
• Use a grounded three wire plug-in for all units with
electric drive motors or electric starting motors.
• Adjust collector housing height to clear gravel or
crushed rock surface.
• Never attempt to make any adjustments while
engine is running (except where specifically
recommended by manufacturer).
• Let engine and machine adjust to outdoor
temperature before starting to clear snow.
• Always wear safety glasses or eye shields during
operation or while performing an adjustment or
repair, to protect eyes from foreign objects that may
be thrown from the machine in any direction.
3. OPERATION
• Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening and auger
at all times.
• Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay alert
for hidden hazards or traffic. Do not carry
passengers.
• After striking a foreign object, stop the engine,
remove wire from spark plug, and thoroughly
inspect the snow thrower for any damage. Repair
the damage before restarting and operating the
snow thrower.
4
• If the snow thrower should start to vibrate
abnormally, stop the engine and check immediately
for the cause. Vibration is generally a warning of
trouble.
• Stop engine whenever you leave the operating
position, before unclogging the collector/impeller
housing or discharge guide, and making any
repairs, adjustments, or inspections. Never place
your hand in the discharge or collector openings.
Use a stick or wooden broom handle to unclog the
discharge opening.
• Take all possible precautions when leaving the unit
unattended. Disengage the collector/impeller, stop
the engine, and remove the key.
• When cleaning, repairing, or inspecting, make
certain collector/impeller and all moving parts have
stopped. Disconnect spark plug wire and keep
away from plug to prevent accidental starting.
• Do not run engine indoors, except when starting
engine and transporting snow thrower in or out of
building. Open doors. Exhaust fumes are
dangerous.
• Do not clear snow across the face of slopes.
Exercise extreme caution when changing direction
on slopes. Do not attempt to clear steep slopes.
• Never operate snow thrower without guards, plates,
or other safety protection devices in place.
• Never operate snow thrower near glass enclosure,
automobiles, window wells, drop off, etc., without
proper adjustments of snow thrower discharge
angle. Keep children and pets away.
• Do not overload machine capacity by attempting to
clear snow at too fast a rate.
• Never operate the machine at high transport
speeds on slippery surfaces. Look behind and use
care when backing.
• Never direct discharge at bystanders or allow
anyone in front of unit.
• Disengage power to collector/impeller when
transporting or not in use.
• Use only attachments and accessories approved
by the manufacturer of snow thrower (such as
wheel weights, counter weights, cabs, etc.).
• 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.
• Muffler and engine become hot and can cause a
burn. Do not touch.
4. MAINTENANCE AND STORAGE
• Check shear bolts, engine mounting bolts, etc., at
frequent intervals for proper tightness to be sure
equipment is in safe working condition.
• Never store the machine with fuel in the fuel tank
inside a building where ignition sources are
present, such as hot water and space heaters,
clothes dryers, and the like. Allow engine to cool
before storing in any enclosure.
• Always refer to operator's manual instructions for
important details if snow thrower is to be stored for
an extended period.
• Run machine a few minutes after throwing snow to
prevent freeze up of collector/impeller.
• Check clutch controls periodically to verify they
engage and disengage properly and readjust if
necessary. Refer to operator's manual for
adjustment instructions.
WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to
persons who read, understand and follow the warnings and instructions in this manual and

2. Then engage the traction control clutch grip. The
wheels should stop turning.
3. Now release the traction control clutch grip, and
push the unit again. Move the shift lever back to
the fast reverse position, then all the way forward
again. There should be no resistance in the shift
lever, and the wheels should keep turning.
4. If you have resistance when moving the shift lever
or the wheels stop when they should not, loosen
the jam nut on the traction control cable and
unthread the cable one turn. If the wheels do not
stop when you engage the traction control clutch
grip, loosen the jam nut on the traction control
cable and thread the cable in one turn. Recheck

120 volt AC household current. It must
be properly grounded at all times to
avoid the possibility of electric shock
which may be injurious to the operator.
Follow all instructions carefully. If the
house wiring system is not a three-wire
grounded system, do not use this
electric starter under any conditions.
Follow all instructions carefully. Determine that your
house wiring is a three wire grounded system. Ask a
licensed electrician if you are not certain. If your
house wiring system is not a three-wire grounded
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 the power cord, always connect
cord to starter on engine first, then plug the other
end into a three-hole grounded receptacle.

starter will not harm engine or starter. Disconnect
the power cord from receptacle first, and then from
switch box.
Recoil Starter:
With engine running, pull starter rope with a rapid,
continuous full arm stroke three or four times. Pulling
the starter rope will produce a loud clattering sound,
which is not harmful to the engine or starter.
3. To stop engine, remove the ignition key. Do not
turn key. Disconnect the spark plug wire from
the spark plug to prevent accidental starting
while equipment is unattended.
NOTE: Do not lose ignition key. Keep it in a safe
place. Engine will not start without the ignition key.
4. Wipe all snow and moisture from the carburetor
cover in the area of the control levers. Also,
move control levers back and forth several
times. Leave throttle control lever in the STOP or
OFF position. Leave choke control in the FULL
choke position.
TO ENGAGE DRIVE/AUGER
1. With the engine running near top speed, move
shift lever into one of the FORWARD or
REVERSE positions. Select a speed appropriate
for the snow conditions that exist. Use the
slower speeds until you are familiar with the
operation of the snow thrower.
2. Squeeze the left hand auger control clutch to
engage auger.
3. While the left hand auger control clutch is
engaged, engage the right hand traction control
clutch.
NOTE: NEVER move shift lever without first
releasing the drive clutch.
TIRE CHAINS (OPTIONAL)
Use tire chains when extra traction is necessary.
OPERATING TIPS
NOTE: Allow the engine to warm up for a few
minutes as the engine will not develop full power
until it reaches operating temperature.
WARNING: Temperature of muffler and
surrounding areas may exceed 150oF.
Avoid these areas.
• For most efficient snow removal, remove
snow immediately after it falls.
• Discharge snow downwind whenever
possible. Slightly overlap each previous
swath.
14
• Set the skid shoes 1/4" below the scraper bar
for normal usage. The skid shoes may be
adjusted upward for hard-packed snow. Adjust
downward when using on gravel or crushed
rock.
• Be certain to follow the precautions listed
under ‘‘To Stop Engine’’ in previous column to
prevent possible freeze-up.
• Clean the snow thrower thoroughly after each
use.
SECTION 8: ADJUSTMENTS
WARNING: Never attempt to clean
chute or make any adjustments while
engine is running.
ADJUSTING CHUTE
You can control the distance that snow is thrown by
adjusting the angle of the chute assembly. The
sharper the angle, the shorter the distance snow is
thrown.
1. To adjust the chute, loosen the hand knob. See
Figure 24.
2. Pivot the top of the chute assembly to the
position desired.
Figure 24
ADJUSTING SKID SHOE
The space between the shave plate and the ground
can be adjusted by adjusting the skid shoe. Slide the
skid shoe upwards and lower the housing to remove
snow close to the ground. Slide skid shoe
downwards and raise the housing to remove snow
from uneven ground like gravel. For more details,
refer to Adjusting the Skid Shoes in section 5.
ADJUSTING TRACTION CONTROL
CLUTCH
Refer to the Final Adjustments section on page 10
for instructions to adjust the traction control clutch. If
you are not sure whether you have been able to
adjust the traction control clutch properly, check as
follows.
1. Drain the gasoline from the snow thrower or put
a plastic film under the gas cap if the snow
thrower has already been operated. Tip the
snow thrower forward onto the auger housing.
2. Remove the frame cover underneath the snow
thrower by removing the six self-tapping screws.
3. With the traction control clutch released, check if
there is clearance between the friction wheel
and the drive plate in all positions of the shift
lever. For correct adjustment there has to be
enough clearance.
4. With the traction control clutch engaged, check if
the friction wheel is contacting the drive plate.
See Figure 25.
5. If adjustment is necessary, loosen the jam nut
on the traction control cable, and thread cable in
or out as necessary.
6. Tighten the jam nut to secure the cable when
correct adjustment is reached. Reassemble the
frame cover with six self-tapping screws.

CARBURETOR ADJUSTMENT
WARNING: 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.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual packed with
your unit for carburetor adjustment information.
DRIVE WHEELS
The wheels may be adjusted for two different
methods of operation. The adjustment is made by
placing the klick pins in one of two different holes on
the right side of the unit. See Figure 26.
1. One Wheel Driving—Place klick pin in the
outside axle hole on the right side. This position
gives power drive to the left wheel only, making

MANUFACTURER’S LIMITED WARRANTY FOR:
The limited warranty set forth below is given by MTD
PRODUCTS INC (“MTD”) with respect to new merchan-
dise purchased and used in the United States, its posses-
sions and territories.
MTD warrants this product against defects in material and
workmanship for a period of two (2) years commencing on
the date of original purchase and will, at its option, repair or
replace, free of charge, any part found to be defective in
material or workmanship. This limited warranty shall only
apply if this product has been operated and maintained in
accordance with the Operator’s Manual furnished with the
product, and has not been subject to misuse, abuse, com-
mercial use, neglect, accident, improper maintenance,
alteration, vandalism, theft, fire, water or damage because
of other peril or natural disaster. Damage resulting from the
installation or use of any accessory or attachment not
approved by MTD Products Inc. for use with the product(s)
covered by this manual will void your warranty as to any
resulting damages.
Normal wear parts or components thereof are subject to
separate terms as follows: All normal wear part or compo-
nent failures will be covered on the product for a period of
90 days regardless of cause. After 90 days, but within the
two year period, normal wear part failures will be covered
ONLY IF caused by defects in material or workmanship of
OTHER component parts. Normal wear parts and compo-
nents include, but are not limited to, belts, blades, blade
adapters, grass bags, rider deck wheels, seats, snow
thrower skid shoes, shave plates and tires. Batteries are
covered by a 90-day limited replacement warranty.
HOW TO OBTAIN SERVICE: Warranty service is avail-
able, WITH PROOF OF PURCHASE THROUGH YOUR
LOCAL AUTHORIZED SERVICE DEALER. To locate the
dealer in your area, please check for a listing in the Yellow
Pages or contact the Customer Service Department of
MTD PRODUCTS INC by calling 1-800-800-7310 or writ-
ing to P.O. Box 368022, Cleveland, Ohio 44136-9722. No
product returned directly to the factory will be accepted
unless prior written permission has been extended by the
Customer Service Department of MTD PRODUCTS INC.
This limited warranty does not provide coverage in the
following cases:
a. The engine or component parts thereof. These items
carry a separate manufacturer’s warranty. Please
refer to the applicable manufacturer’s warranty on
these items.
b. Routine maintenance items such as lubricants, filters,
blade sharpening and tune-ups, or adjustments such
as brake adjustments, clutch adjustments or deck
adjustments; and normal deterioration of the exterior
finish due to use or exposure.
c. Log splitter pumps, valves and cylinders have a sepa-
rate one year warranty.
d. MTD does not extend any warranty for products sold
or exported outside of the United States of America,
its possessions and territories, except those sold
through MTD’s authorized channels of export distribu-
tion.
No implied warranty, including any implied warranty of
merchantability or fitness for a particular purpose,
applies after the applicable period of express written
warranty above as to the parts as identified. No other
express warranty or guaranty, whether written or oral,
except as mentioned above, given by any person or
entity, including a dealer or retailer, with respect to any
product shall bind MTD. During the period of the War-
ranty, the exclusive remedy is repair or replacement of
the product as set forth above. (Some states do not
allow limitations on how long an implied warranty lasts, so
the above limitation may not apply to you.)
The provisions as set forth in this Warranty provide the
sole and exclusive remedy arising from the sales. MTD
shall not be liable for incidental or consequential loss
or damages including, without limitation, expenses
incurred for substitute or replacement lawn care ser-
vices, for transportation or for related expenses, or for
rental expenses to temporarily replace a warranted
product. (Some states do not allow the exclusion or limita-
tion of incidental or consequential damages, so the above
exclusion or limitation may not apply to you.)
In no event shall recovery of any kind be greater than the
amount of the purchase price of the product sold. Alteration
of the safety features of the product shall void this War-
ranty. You assume the risk and liability for loss, damage, or
injury to you and your property and/or to others and their
property arising out of the use or misuse or inability to use
the product.
This limited warranty shall not extend to anyone other than
the original purchaser, original lessee or the person for
whom it was purchased as a gift.
How State Law Relates to this Warranty: This limited
warranty gives you specific legal rights, and you may also
have other rights which vary from state to state.
