openings while operating the snowthrower.
• Keep your hands, feet, and any other part
of your body or clothing away from
concealed, moving, or rotating parts.
• Use a stick, not your hand, to remove
obstructions from the discharge chute or
auger housing.
• Before adjusting, cleaning, repairing, and
inspecting the snowthrower and before
unclogging the discharge chute, stop the
engine and wait for all moving parts to
stop. Remove the key.
2
Preparation
•
Thoroughly inspect the area where the
equipment is to be used and remove all
doormats, sleds, boards, wires, and other foreign
objects.
•
Do not operate the equipment without wearing
adequate winter outer garments. Wear footwear
that will improve footing on slippery surfaces.
•
Adjust the auger housing height to clear gravel
or crushed rock surface.
•
Never attempt to make any adjustments while
the engine is running, except when specifically
recommended by Toro.
Safety
•
Never operate the snowthrower without proper
guards, plates, or other safety protective devices
in place.
•
Never operate the snow thrower near glass
enclosures, automobiles, window wells,
drop-offs, and the like without proper adjustment
of the snow discharge angle. Keep children and
pets away.
Operation
•
Do not overload the machine capacity by
attempting to clear snow at too fast a rate.
•
Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at all
times.
•
Never operate the machine at high transport
speeds on slippery surfaces. Look behind and
use care when moving in reverse.
•
Exercise extreme caution when operating on or
crossing gravel drives, walks, or roads. Stay alert
for hidden hazards or traffic. Do not carry
passengers.
•
Never direct discharge at bystanders or allow
anyone in front of the unit.
•
Disengage power to the auger/impeller when the
snowthrower is transported or not in use.
•
Never operate the snowthrower without good
visibility or light.
•
Let engine and machine adjust to outdoor
temperatures before starting to clear snow.
•
The operation of any powered machine can
result in foreign objects being thrown into the

•
•
After striking a foreign object, stop the engine,
remove the wire(s) from the spark plug(s),
thoroughly inspect the snowthrower for any
damage, and repair the damage before restarting
and 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 the auger/impeller and all moving parts
have stopped. Disconnect the spark plug wire(s)
and keep the wire away from the plug to prevent
someone from accidentally starting the engine.
Do not clear snow across the face of slopes.
Exercise extreme caution when changing
direction on slopes. Do not attempt to clear steep
slopes.

Always refer to the operator’s manual for
important details if the snowthrower is to be
stored for an extended period.
•
Maintain or replace safety and instruction labels,
as necessary.
•
Run the machine a few minutes after throwing
snow to prevent freeze-up of the auger/impeller.

POTENTIAL HAZARD
• Rotating auger can cut off fingers, hands or
other body parts and throw objects.
WHAT CAN HAPPEN
• Contact with rotating auger and thrown
debris can cause severe injury or death.
HOW TO AVOID THE HAZARD
• Stay away from the discharge and auger
openings while operating the snowthrower.
• Keep your hands, feet, and any other part
of your body or clothing away from
concealed, moving or rotating parts.
• Use a stick, not your hand, to remove
obstructions from discharge chute or auger
housing.
• Before adjusting, cleaning, repairing and
inspecting the snowthrower and before
unclogging the discharge chute, shut off the
engine and wait for all moving parts to
stop. Move the power take off (PTO) to
“OFF” and rotate the ignition key to
“OFF.” Remove the key.

Operation
Tips for Throwing Snow
Remove snow as soon as possible after it falls. This
produces best snow removal results.
Adjust skids to match the type of surface being
cleaned; refer to Adjusting Skids.
The snowthrower is designed to clean snow down to
the contact surface, but there are times when the front
of the snowthrower may tend to ride up. If this
happens, reduce forward speed.
Discharge snow downwind whenever possible, and
overlap each pass to ensure complete snow removal.
If wheels slip, shift into a lower gear to reduce
forward speed.
Run snowthrower for a few minutes after clearing
snow so moving parts do not freeze. Engage power
take off (PTO) to clear any remaining snow from
inside housing.
Do not overload snowthrower by clearing snow at too
fast a rate. If engine slows down, reduce forward
speed.
Always use full throttle (maximum engine speed)
when throwing snow.
In wet or slushy conditions, clogging of the discharge
chute will be reduced by maintaining maximum
engine speed and by not overloading the engine.
In some snow and cold weather conditions, some
controls and moving parts may freeze. Therefore,
when any control becomes hard to operate, stop the
machine and wait for all moving parts to stop; then
check all parts for freeze up. DO NOT USE
EXCESSIVE FORCE AND TRY TO OPERATE
THE CONTROLS WHEN FROZEN. Free all
controls and moving parts before operating.

Maintenance
Adjusting Skids
Replacing Scraper Blade
The distance between the scraper blade and the
ground is controlled by skids on each side of the
housing. The height can be adjusted so the scraper
blade will not catch on uneven surfaces
The scraper blade contacts the ground preventing
damage to the snowthrower housing. Periodically
inspect the scraper blade for wear. When scraper
becomes worn, before working surface contacts the
housing, replace the scraper blade.
1.
Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2.
Move snowthrower to a level surface.
3.
Loosen nuts securing skids to the housing until
the skids slide up and down easily (Fig. 35).
4.
Raise or lower skids equally on both sides, to
obtain level scraping action, and tighten nuts
(Fig. 35).
Note:
1.
Disengage the power take off (PTO), set the
parking brake, and turn the ignition key to
“OFF” to stop the engine. Remove the key.
2.
