Safety
This 2-stage snowthrower meets or exceeds the B71.3
specifications of the American National Standards
Institute in effect at the time of production.
To ensure maximum safety and best performance, and
to gain knowledge of the product, it is essential that you
and any other operator of the snowthrower read and
understand the contents of this manual before the
engine is ever started.
This is the safety alert symbol. It is used to alert you
to potential personal injury hazards. Obey all safety
messages that follow this symbol to avoid possible
injury or death.
Improperly using or maintaining this snowthrower
could result in injury or death. To reduce this potential,
comply with the following safety instructions.
• Never allow children to operate the snowthrower. Never
allow adults to operate the snowthrower without proper
instruction.
• Keep the area of operation clear of all persons
(particularly small children) and pets.
• Exercise caution to avoid slipping or falling, especially
when operating the snowthrower in reverse.
Preparation
• Thoroughly inspect the area where you will use the
snowthrower. Remove all doormats, sleds, boards,
wires, and other foreign objects.
• Before starting the engine, disengage all clutches. For
Power Shift models, shift the snowthrower into
neutral as well.
• Do not operate the snowthrower without wearing
adequate winter garments. Wear footwear that will
improve your footing on slippery surfaces.
• Handle fuel with care; it is highly flammable.
– Use an approved fuel container.
– Never add fuel to a running or hot engine.
– Fill the fuel tank outdoors with extreme care. Never
fill the fuel tank indoors.
– Replace the fuel tank cap securely and wipe up any
spilled fuel.
• Use only the power cord supplied with the snowthrower
and a receptacle appropriate for use with the power cord
for electric-starting motors.
• Adjust the auger housing height to clear gravel or
crushed rock surface.
• Never attempt to make any adjustments while the
engine is running, except where specifically
recommended by Toro.
• Let the engine and the snowthrower adjust to the
outdoor temperature before starting to clear snow.
Safe Operating Practices
The following instructions have been adapted from the
ANSI/OPEI B71.3–1995 standard and the ISO 8437:1989
standard. Information or terminology specific to Toro
snowthrowers is enclosed in parenthesis.
• Operating any powered machine can result in foreign
objects being thrown into the eyes. Always wear safety
glasses or eye shields while operating, adjusting, or
repairing the snowthrower.

Operation
• Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
• Never operate the snowthrower without good visibility
or light. Always be sure of your footing, and keep a
firm hold on the handle. Walk; never run.
• Exercise extreme caution when operating on or crossing
gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic.
• After striking a foreign object, stop the engine, remove
the wire from the spark plug, thoroughly inspect the
snowthrower for any damage, and repair the damage
before operating the snowthrower.
• If the unit should start to vibrate abnormally, stop the
engine and check immediately for the cause. Vibration
is generally a warning of trouble.
• Stop the engine whenever you leave the operating
position, before unclogging the auger/impeller housing
or discharge chute, and when making any repairs,
adjustments, or inspections.
• When cleaning, repairing, or inspecting, make certain
that the auger/impeller and all moving parts have
stopped. Disconnect the spark-plug wire, and keep the
wire away from the spark plug to prevent someone from
accidentally starting the engine.
• Do not run the engine indoors, except when starting it
and for moving the snowthrower in or out of the
building. Open the outside 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 the snowthrower without proper guards
or other safety devices in place.
• Never operate the snowthrower near glass enclosures,
automobiles, window wells, and drop-offs without
properly adjusting the snow discharge angle. Keep
children and pets away.
• Do not overload the 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
moving in reverse.
• Never direct the discharge at bystanders or allow
anyone in front of the unit.
• Disengage the power to the auger/impeller when the
snowthrower is being transported or when not in use.
• Use only attachments and accessories approved by
Toro, such as wheel weights, counterweights, and cabs.
(Contact your Authorized Service Dealer for
accessories available for your snowthrower.)
Maintenance and Storage
• Check all fasteners at frequent intervals for proper
tightness to be sure that the 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 and clothes dryers. Allow
the engine to cool before storing in any enclosure.
• Always refer to this operator’s manual for important
details if the snowthrower is to be stored for an
extended period.
• Maintain or replace safety and instruction labels when
necessary.
• Run the engine run for a few minutes after clearing the
snow to prevent the auger/impeller from freezing.
Toro Snowthrower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know.
• Rotating auger/impeller can cut off or injure fingers or
hands. Stay behind the handles and away from the
discharge opening while operating the snowthrower.
Keep your face, hands, feet, and any other part of your
body or clothing away from moving or rotating parts.
• Before adjusting, cleaning, repairing, and inspecting the
snowthrower, and before unclogging the discharge
chute, stop the engine, remove the key, and wait for all
moving parts to stop. Also, disconnect the wire from the
spark plug and keep it away from the spark plug to
prevent someone from accidentally starting the engine.
• Use a stick, not your hands, to remove obstructions
from the discharge chute.
• Before leaving the operating position, stop the engine,
remove the key, and wait for all moving parts to stop.
• Do not wear loose-fitting clothing that could get caught
in moving parts.
• If a shield, safety device, or decal is damaged, illegible,
or lost, repair or replace it before beginning operation.
Also, tighten any loose fasteners.
• Do not smoke while handling gasoline.
• When operating the snowthrower on slopes, use the
lower gear. For Power Shift snowthrowers, use the
rear wheel position.

• Do not use the snowthrower on a roof.
• Do not touch the engine while it is running or soon after
it has stopped because the engine may be hot enough to
cause a burn. Do not add oil or check the oil level in the
crankcase while the engine is running.
• Perform only those maintenance instructions described
in this manual. Before performing any maintenance,
service, or adjustment, stop the engine, remove the key
and disconnect the wire from the spark plug. Keeping
the wire away from the spark plug to prevent someone
from accidentally starting the engine. If major repairs
are ever needed, contact your Authorized Service
Dealer.
• Do not change the governor settings on the engine.
• When storing the snowthrower for more than 30 days,
drain the fuel from the fuel tank to prevent a potential
hazard. Store fuel in an approved fuel container.
