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.
1. 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.
2. 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.
2
• 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

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

within the United States of America, its possessions
and territories, MTD PRODUCTS INC will, at its
option, repair or replace, for the original purchaser,
free of charge, any part or parts found to be
defective in material or workmanship. This warranty
covers units which have been operated and
maintained in accordance with the operating
instructions furnished with the unit, and which have
not been subject to misuse, abuse, commercial use,
neglect, accident, improper maintenance or
alteration.
Normal wear parts or components thereof are
subject to separate terms as noted below in the “No
Fault Ninety Day Consumer Warranty” clause.
All normal wear part failures will be covered on this
product for a period of 90 days regardless of cause.
After 90 days, but within the two year period, normal
wear parts failures will be covered ONLY IF caused
by defects in material or workmanship of OTHER
component parts. Normal wear parts are defined as
batteries*, belts, blades, blade adapters, grass
bags, rider deck wheels, seats, snow thrower skid
shoes, shave plates and tires.
How to obtain service: Warranty service is
available, with proof of purchase, through your local
authorized service dealer. To locate the dealer in
your area, please check the yellow pages or contact
the Customer Service Department of MTD
PRODUCTS INC, P. O. Box 368022, Cleveland,
Ohio 44136-9722. Phone 1 (800) 800-7310. The
return of a complete unit will not be accepted by the
factory unless prior written permission has been
extended by the Customer Service Department of
MTD PRODUCTS INC.
Transportation charges: Transportation charges
for the movement of any power equipment unit or
attachment are the responsibility of the purchaser.
Units exported out of the United States: MTD
PRODUCTS INC 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 PRODUCTS INC’s
authorized channels of export distribution.
Other Warranties:
1. The engine or component parts thereof carry
separate warranties from their manufacturers.
Please refer to the applicable manufacturer’s
warranty on these items.
2. *Batteries are covered by a 90-day replacement
warranty.
3. Log splitter pumps, valves and cylinders or

4. All other warranties, express or implied,
including any implied warranty of
merchantability or fitness for a particular
purpose, are hereby expressly disclaimed in
their entirety.
5. The provisions as set forth in this warranty
provide the sole and exclusive remedy of MTD

or damage.
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. Certain disclaimers are not allowed in
some states and therefore they may not apply to
you under all circumstances.
NOTE: This warranty does not cover routine
maintenance items such as lubricants, filters, blade
sharpening and tune-ups, or adjustments such as
brake adjustments, clutch adjustments or deck
adjustments. Nor does this warranty cover normal
deterioration of the exterior finish due to use or
exposure.
