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.

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.

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.

3

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.)

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.

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.

Before Starting

Filling the Engine Crankcase with Oil

The engine comes from the factory with only a few ounces of oil in the crankcase. Before starting the engine, add oil.

The crankcase in models 38079 and 38559 holds 26 ounces

(0.77 liters) of oil, and the crankcase in model 38087 holds

28 ounces (0.83 liters) of oil. However, because there is some oil in the crankcase, do not add the full amount at one time. Use only a high-quality, SAE 5W–30 or SAE 10 weight detergent oil that has the American Petroleum

Institute (API) service classification SF, SG, SH, or SJ. For extremely cold conditions (below 0

°

F or –18

°

C), use

0W–30 weight detergent oil that has the American

Petroleum Institute (API) service classification SF, SG, SH, or SJ.

To add oil:

1. Move the snowthrower to a level surface to ensure an accurate oil level reading.

2. Clean around the dipstick (Fig. 12).

2 m-4063

1.

Dipstick

Figure 12

2.

Fuel tank cap

3. Remove the dipstick by rotating the cap counterclockwise and pulling it out (Fig. 12).

4. Slowly pour about 3/4 of the crankcase capacity of oil into the crankcase.

5. Wipe the dipstick clean with a clean cloth.

6. Install the dipstick into the filler neck, then remove it.

Note: To ensure an accurate oil level reading, you must fully install the dipstick.

7. Read the oil level on the dipstick.

8. If the oil level is below the Add mark on the dipstick,

slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick.

Important Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level on the dipstick reads Full.

9. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight.

Filling the Fuel Tank with

Gasoline

For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in 30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life. You may use leaded gasoline if unleaded gasoline is not available.

Important Do not add oil to the gasoline.

Important Do not use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas. Using these fuels can damage the engine’s fuel system.

Important Do not use gasoline that is more than 30 days old.

Danger

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.

Fill the fuel tank outdoors, in an open area, and when the engine is cold. Wipe up any gasoline that spills.

Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to

1/2 inch (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows the gasoline to expand.

Never smoke when handling gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes.

Store gasoline in an approved fuel container and keep it out of the reach of children.

Never buy more than a 30-day supply of gasoline.

12

Danger

When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property.

Always place gasoline containers on the ground and away from your vehicle before filling.

Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

When practical, remove gasoline-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

If this is not possible, then refuel such equipment on a truck or trailer from a portable container, not from a gasoline dispenser nozzle.

If you must use a gasoline dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Use a fuel stabilizer/conditioner regularly during operation and storage. A stabilizer/conditioner cleans the engine during operation and prevents gum-like varnish deposits from forming in the engine during periods of storage.

Important Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

1. Clean around the fuel tank cap (Fig. 12).

2. Remove the fuel tank cap.

3. Fill the fuel tank with unleaded to within 1/4 to 1/2 inch

(6 to 13 millimeters) from the top of the tank. Do not fill into the filler neck.

Important Do not fill the fuel tank more than 1/4 inch

(6 millimeters) from the top of the tank because the gasoline must have room to expand.

4. Install the fuel tank cap and wipe up any spilled gasoline.

Checking the Tire Pressure

Check the pressure of the tires because they are overinflated at the factory for shipping. Reduce the pressure equally in both tires to between 12 and 15 psi

(82 and 103 kPa).

Remove the fasteners from their holes before installing the carburetor heater box.

Starting the Engine

Important Ensure that there are no obstructions in the auger/impeller and the discharge chute before you operate the snowthrower. Use a stick, not your hand, to remove an obstruction from the auger/impeller or the discharge chute.

1. Connect the wire to the spark plug.

2. Move the speed shift control to the N (Neutral) position and the throttle to the Fast position.

3. Release the auger/impeller drive control lever and the traction control lever (Fig. 13).

4. Open the fuel shutoff valve below the fuel tank

(Fig. 15).

5. Rotate the choke (Fig. 14) to the On position.

6. Insert the ignition key (Fig. 14).

Important Do not use the primer or the choke if the engine has been running and is hot. Excessive priming may flood the engine and prevent it from starting.

7. Cover the hole in the center of the primer (Fig. 14) with your thumb and slowly push in the primer 3 times, pausing a moment between pushes.

8. Grasp the recoil starter handle (Fig. 17) and pull it out slowly until positive engagement results; then pull the handle vigorously to start the engine.

9. Keep a firm grip on the starter handle and return the rope slowly.

Note: If engine does not start or if the air temperature is

–10 F (–23 C) or colder, the engine may need additional priming. After pushing in the primer, try to start the engine before priming again.

10. After the engine starts, immediately rotate the choke

(Fig. 14) to the 3/4 position. As the engine warms up, rotate the choke to the 1/2 position. When the engine warms up sufficiently, rotate the choke to the Off position.

Important Ensure that the auger and impeller do not rotate while the auger/impeller drive control lever is in the

Disengaged position. Stand in the operating position and look around to the side of the auger housing (Fig. 20). A large screw head on the side of the auger housing rotates when the auger and impeller rotate (Fig. 20). If the auger and impeller rotate while the engine runs and the auger/impeller drive control lever is disengaged, stop

the snowthrower immediately. Refer to Adjusting the

Auger/Impeller Drive Belt on page 21. If the problem persists, take the snowthrower to an Authorized Service

Dealer for service.

Snowthrowing Tips

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. Disconnect the wire from the spark plug and keep it away from the plug to prevent someone from accidentally starting the engine.

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.

Adjust the skids to match the type of surface being cleaned. Refer to Adjusting the Skids and the Scraper on page 20.

In snowy and cold conditions, some controls and moving parts may freeze. Do not use excessive force

when trying to operate frozen controls. If you have difficulty operating any control or part, start the engine and let it run for a few minutes.

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

Always use the Fast throttle position when throwing snow.

Overlap each swath to ensure complete snow removal.

Discharge the snow downwind whenever possible.

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

In wet or slushy conditions, maintain maximum engine speed, and do not overload the engine to prevent clogging the discharge chute.

If the front of the snowthrower tends to ride up, reduce the forward speed by shifting the snowthrower into a lower gear. If the front still tends to ride up, lift up on both handgrips to hold down the front of snowthrower.

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

After clearing the snow, let the engine run for a few minutes to prevent moving parts from freezing. Engage the auger/impeller to clear any remaining snow from inside the housing. Shut off the engine, wait for all moving parts to stop, and remove all ice and snow from the snowthrower.

With the engine shut off, pull the recoil starter handle several times to prevent the recoil starter from freezing up.

When you are not using the snowthrower, close the fuel shutoff valve and remove the key.

Caution

If you leave the wire on the spark plug, someone could accidently start the engine and seriously injure you or other bystanders.

Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.

Checking the Engine Oil Level

Every time you use the snowthrower, first ensure that the oil level is between the Add and the Full marks on the dipstick.

1. Stop the engine and wait for all moving parts to stop.

2. Move the snowthrower to a level surface to ensure an accurate oil level reading.

3. Clean around the dipstick (Fig. 12).

4. Remove the dipstick by rotating the cap counterclockwise and pulling it out (Fig. 12).

5. Wipe the dipstick clean with a clean cloth.

6. Install the dipstick into the filler neck, then remove it.

Note: To ensure an accurate oil level reading, you must fully install the dipstick.

7. Read the oil level on the dipstick.

8. If the oil level is below the Add mark on the dipstick,

slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick.

Note: Use only a high-quality, SAE 5W–30 or SAE 10 weight detergent oil that has the American Petroleum

Institute (API) service classification SF, SG, SH, or SJ.

For extremely cold conditions (below 0

°

F or –18

°

C), use 0W–30 weight detergent oil that has the American

Petroleum Institute (API) service classification SF, SG,

SH, or SJ.

Important Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level on the dipstick reads Full.

9. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight.

Checking the Auger Gearbox

EP transmission oil to the gearbox until the point of overflow. Do not use synthetic gear oil.

19

8. Install the pipe plug in the gearbox.

9. Connect the wire to the spark plug.

Adjusting the Skids and the

Scraper

Adjust the skids and the scraper initially and then as needed to ensure that the auger does not contact the paved or gravel surface. Also, adjust them as needed to compensate for wear.

1. Stop the engine and wait for all moving parts to stop.

2. Move the snowthrower to a level surface and shift the wheels to the front position.

3. Disconnect the wire from the spark plug and ensure that the wire does not contact the plug (Fig. 25).

4. Check the tire pressure in the tires. Refer to Checking the Tire Pressure on page 13.

5. Loosen the 4 flange bolts that secure both skids to the auger side plates (Fig. 10) until the skids slide up and down easily.

6. Support the auger blades so that they are at least

1/8 inch (3 millimeters) off the ground (Fig. 27).

For Concrete and Asphalt Surfaces:

If the snowthrower does not clear the snow close enough to the pavement, adjust the skids to lower the scraper; if the pavement surfaces are cracked, rough, or uneven, adjust the skids to raise the scraper.

For Gravel Surfaces:

Support the auger blades a few inches (centimeters) above the ground, and adjust the skids to prevent the snowthrower from picking up rocks.

8. To adjust the scraper, loosen the carriage bolts that secure the scraper to the auger housing (Fig. 27), level the scraper, and tighten the carriage bolts.

9. Move the skids down as far as possible.

10. Tighten the 2 front flange bolts that secure both skids to the auger side plates.

11. Connect the wire to the spark plug.

Storage

Warning

Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If the product is stored in an area with an open flame, the gasoline fumes may ignite and cause an explosion.

Do not store the snowthrower in a house (living area), basement, or any other area where ignition sources may be present, such as hot water and space heaters, clothes dryers, furnaces, and other like appliances.

Preparing the Fuel System

1. Add stabilizer/conditioner to the fuel in the fuel tank as directed.

2. Run the engine for 10 minutes to distribute conditioned fuel through the fuel system.

3. Stop the engine, allow it to cool, and drain the fuel tank or run the engine until it stops. Refer to Emptying the

Fuel Tank on page 24.

4. Start the engine and run it until it stops.

5. Choke or prime the engine, start it a third time, and run the engine until it will not start.

6. Dispose of unused fuel properly. Recycle it according to local codes, or use it in your automobile.

Note: Do not store stabilized gasoline for more than 90 days.

Preparing the Engine

1. While the engine is still warm, change the engine oil.

Refer to Changing the Engine Oil on page 23.

2. Remove the spark plug.

3. Use an oil can to squirt 2 teaspoons of oil into the spark plug hole.
