Improperly using or maintaining this machine could result in injury or death. To reduce this potential, comply with the following safety instructions.

This machine is capable of amputating hands and feet and of throwing objects. Failure to observe the following safety instructions could result in serious injury.

Training

Read, understand, and follow all instructions on the machine and in the manual(s) before operating this machine. Be thoroughly familiar with the controls and the proper use of the machine. Know how to stop the machine and disengage the controls quickly.

Never allow children to operate the machine. Never allow adults to operate the machine without proper instruction.

Keep the area of operation clear of all persons, particularly small children.

Exercise caution to avoid slipping or falling.

Preparation

Thoroughly inspect the area where the machine is to be used and remove all doormats, sleds, boards, wires, and other foreign objects.

Do not operate the machine without wearing adequate winter garments. Avoid loose fitting clothing that can get caught in moving parts. Wear footwear that will improve footing on slippery surfaces.

Handle fuel with care; it is highly flammable.

Use an approved fuel container.

Never add fuel to a running engine or hot engine.

Fill fuel tank outdoors with extreme care. Never fill fuel tank indoors.

Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle, before filling.

When practical, remove gas-powered machinery from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such machinery on a trailer with a portable container, rather than from a gasoline dispenser nozzle.

Keep the nozzle in contact with the rim of the fuel tank or container opening at all times, until refueling is complete. Do not use a nozzle lock-open device.

Replace gasoline cap securely and wipe up spilled fuel.

If fuel is spilled on clothing, change clothing immediately.

Do not attempt to clear snow from a gravel or crushed rock surface. This machine is intended for use only on paved surfaces.

Never attempt to make any adjustments while the engine is running (except when specifically recommended by manufacturer).

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.

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.

After striking a foreign object, stop the engine, remove the ignition key, thoroughly inspect the machine for any damage, and repair the damage before restarting and operating the machine.

If the machine 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 rotor blade housing

or discharge chute, and when making any repairs, adjustments or inspections.

When cleaning, repairing, or inspecting the machine, stop the engine and make certain that the rotor blades and all moving parts have stopped.

Do not run the engine indoors, except when starting the engine and for transporting the machine in or out of the building. Open the outside doors; exhaust fumes are dangerous.

Exercise extreme caution when operating on slopes.

Never operate the machine without proper guards and other safety protective devices in place and working.

Never direct the discharge toward people or areas where property damage can occur. Keep children and others away.

Do not overload the machine capacity by attempting to clear snow at too fast a rate.

Look behind and use care when backing up with the machine.

Disengage power to the rotor blades when machine is transported or not in use.

Never operate the machine without good visibility or light. Always be sure of your footing, and keep a firm hold on the handles. Walk; never run.

Never touch a hot engine or muffler (Figure 3).

Clearing a Clogged Discharge

Chute

Hand contact with the rotating rotor blades inside the discharge chute is the most common cause of injury associated with snowthrowers. Never use your hand to clean out the discharge chute.

To clear the chute:

Ensure that the engine is in the Off position.

Wait 10 seconds to be sure the rotor blades have stopped rotating.

Always use a clean-out tool, not your hands.

Maintenance and Storage

Check all fasteners at frequent intervals for proper tightness to be sure the machine 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 heaters, space heaters, or clothes dryers. Allow the engine to cool before storing in any enclosure.

Always refer to the Operator’s Manual for important details if the machine 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 rotor blades.

Toro Snowthrower Safety

The following list contains safety information specific to Toro products or other safety information that you must know.

Rotating rotor blades can injure fingers or hands.

Stay behind the handles and away from the discharge opening while operating the machine. 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 machine, and before unclogging the discharge chute, stop the engine, remove the key, and wait for all moving parts to stop.

Before leaving the operating position, stop the engine, remove the ignition key, and wait for all moving parts to stop.

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.

Do not use the machine 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.

Perform only those maintenance instructions described in this manual. Before performing any maintenance, service, or adjustment, stop the engine and remove the key. If major repairs are ever needed, contact an Authorized Service Dealer.

Do not change the governor settings on the engine.

When storing the machine for more than 30 days, drain the fuel from the fuel tank to prevent a potential hazard. Store fuel in an approved fuel container. Remove the key from the ignition switch before storing the machine.

Purchase only genuine Toro replacement parts and accessories.

Filling the Engine with Oil

No Parts Required

Procedure

Your machine does not come with oil in the engine, but it does come with a bottle of oil.

Important: Before starting the engine, fill the engine with oil.

Note: The bottle of oil may contain an ounce or two more than the engine requires. Do not overfill or under fill the engine.

Max fill:0.6 L (20 oz), type: automotive detergent oil with an API service classification of SJ, SL, or higher.

Use Figure 7 below to select the best oil viscosity for the outdoor temperature range expected:

3.Unscrew the oil-fill cap and remove it.

4.With the machine in the operating position, carefully pour oil into the crankcase. Wait 3 minutes for the oil to settle and add enough to bring it to the point of overflow. There should be very little, if any, oil left in the bottle.

Note: You may tip the machine forward (handle up) to make adding oil easier. Remember to return the machine to the operating position before checking the oil level.

Important: Do not tip the machine all the way forward onto its nose, or fuel may leak out of the machine.

DANGER

Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others.

• To prevent a static charge from igniting the gasoline, place the container and/or machine on the ground before filling, not in a vehicle or on an object.

• Fill the tank outdoors when the engine is cold. Wipe up spills.

• Do not handle gasoline when smoking or around an open flame or sparks.

• Store gasoline in an approved fuel container, out of the reach of children.

• Do not tip the machine backward with fuel in the fuel tank; otherwise, fuel may leak out of the machine.

7

Filling the Fuel Tank

For best results, use only clean, fresh, unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

Oxygenated fuel with up to 10% ethanol or 15% MTBE by volume is acceptable.

Do not use ethanol blends of gasoline (such as E15 or E85) with more than 10% ethanol by volume.

Performance problems and/or engine damage may result which may not be covered under warranty.

Do not use gasoline containing methanol.

Do not store fuel either in the fuel tank or fuel containers over the winter unless a fuel stabilizer is used.

Do not add oil to gasoline.

Figure 10

1.6 mm (1/4 inch)

Note: For best results, purchase only the quantity of gasoline that you expect to use in 30 days. Otherwise, you may add fuel stabilizer to newly purchased gasoline to keep it fresh for up to 6 months.

Checking the Engine Oil Level

Service Interval: Before each use or daily—Check the engine oil level and add oil if necessary.

1.Move the machine to a level surface.

2.Clean around the oil-fill cap (Figure 11).
