Safety

Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with the safety instructions in the traction unit operator’s manual and always pay attention to the safety alert WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death.

symbol, which means CAUTION,

• 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.

• Let engine and machine adjust to outdoor temperatures

before starting to clear snow.

Danger

When the snowthrower is in operation, the impeller and auger can be rotating and cut off or injure hands and feet.

• 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.

• Use a stick, not your hands, to remove an

obstruction from the discharge chute.

• Stay behind the handles and away from the

discharge opening while operating the snowthrower.

• Keep face, hands, feet, and any other part of

your body or clothing away from concealed, moving, or rotating parts.

Warning

The auger/impeller may pick up and throw stones, toys, and other foreign objects, causing serious personal injury to the operator or to bystanders.

• Keep the area to be cleared free of all objects

that could be picked up and thrown by the auger/impeller.

• Keep all children and pets away from area of

operation.

General Snowthrower Safety

The following instructions have been adapted from the ANSI/OPEI and ISO standards.

Preparation

• Thoroughly inspect the area where the equipment is to

be used and remove all doormats, sleds, boards, wires, and other foreign objects.

• The operation of any powered machine can result in

foreign objects being thrown into the eyes. Always wear safety glasses or eye shields during operation or while performing an adjustment or repair.

Operation

• Do not put hands or feet near or under rotating parts.

Keep clear of the discharge opening 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

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.

• 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.

• Do not overload the machine capacity by attempting to

clear snow at too fast a rate.

Page 4

• Never operate the machine at high transport speeds on

slippery surfaces. Look behind and use care when moving in reverse.

• 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.

Maintenance and Storage

• Check fasteners at frequent intervals for proper

tightness to be sure the equipment is in safe working condition.

• 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.

• Perform only those maintenance instructions described

in this manual. Before performing any maintenance, service, or adjustment, stop the engine, remove the key and pull the wire(s) from the spark plug(s), keeping it away from the plug(s) to prevent someone form accidentally starting the engine. If major repairs are ever needed, contact your Authorized Toro Service Dealer.

• To ensure the best performance and safety, purchase

only genuine Toro replacement parts and accessories to keep the Toro all Toro. Do not use “Will Fit”

replacement parts and accessories as they could cause a safety hazard.

Adjusting the Discharge Chute

Danger

When the snowthrower is in operation, the impeller and auger can be rotating and cut off or injure hands and feet.

• Before adjusting, cleaning, repairing and

inspecting the snowthrower, and before unclogging the discharge chute, disengage the

PTO, stop the engine, remove the key, and wait for all moving parts to stop.

• Use a stick, not your hands, to remove an

obstruction from the discharge chute.

• Stay away from the discharge and auger

openings while operating the snowthrower.

• Keep face, hands, feet, and any other part of

your body or clothing away from concealed, moving, or rotating parts.

You can rotate the discharge chute 180 degrees side to side by turning the crank handle (fig. 29).

Page 16

You can adjust the height and distance snow is thrown by moving the chute deflector, on top of the discharge chute, up and down (fig. 29).

Tips for Throwing Snow

Remove snow as soon as possible after it falls. This produces the best snow removal results.

Adjust the 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 the wheels slip, shift into a lower gear to reduce forward speed.

Run the snowthrower for a few minutes after clearing snow so moving parts do not freeze. Engage the PTO to clear any remaining snow from inside the housing.

Do not overload the snowthrower by clearing snow at too fast a rate. If the engine slows down, reduce forward speed.

Always use full throttle (maximum engine speed) when throwing snow.

In wet or slushy conditions, reduce clogging of the discharge chute 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 trying to operate frozen controls.

Free all controls and moving parts before operating.

level scraping action, then tighten the nuts (fig. 32).

Note: On smooth, paved surfaces, the scraper blade can be close to the surface On uneven, gravel or crushed rock surfaces, adjust the skids to raise the scraper, to prevent catching or picking up rocks.

Important The scraper should be higher above the

pavement if the pavement surfaces on which the snowthrower will be used are cracked, rough or uneven.

Reversing the Scraper Blade

The scraper blade contacts the ground preventing damage to the snowthrower housing. Periodically inspect the scraper blade for wear. When the scraper becomes worn, before the working surface contacts the housing, reverse the scraper blade.
