HOW TO AVOID THE HAZARD

Do not run engine indoors or in an enclosed area.

Safe Operating Practices

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

This mower is designed for cutting and recycling grass or, when equipped with a grass bag, for catching cut grass. Any use for purposes other than these could prove dangerous to the operator or bystanders.

Note: This engine is NOT equipped with a spark arrester muffler. Use or operation of this mower in the State of California on any forest-covered, brush-covered or unimproved grass-covered land, without an approved spark arrester muffler, is a violation of the law. Other states may have similar laws.

General Operation

Read this manual carefully before operating the mower. Become familiar with the controls and proper use of the mower. Never allow children under 16 years of age to operate the mower. Never allow adults to operate mower without proper instructions.

The operator of the mower is responsible for keeping everyone, especially children and pets, away from area of operation. The operator is responsible for accidents or hazards occurring to other people or their property.

Thoroughly inspect the area where the mower will be used and remove sticks, stones, wire, and debris that could be picked up and thrown by the mower. Watch for foreign objects while mowing.

Wear long pants and substantial shoes. Do not operate the mower while wearing open-toed shoes, jewelry, loose clothing, or when barefoot.

Check the fuel level before starting the engine. Because fuel is highly flammable, handle it carefully.

Use an approved fuel container.

Fill the fuel tank outdoors, not indoors. Never add fuel to an engine that is running or hot.

Install a gas cap on the fuel container and gas tank, and wipe up any spilled gasoline before starting the engine.

Do not smoke while refueling.

Keep all guards, shields, safety devices, cover-deflector assembly, optional grass catcher, optional side discharge chute, and/or optional discharge tunnel plug in place. Repair or replace damaged parts, including decals. Check all safety devices before each use.

3

The engine, blade, and self±propel drive (self-propelled model) are designed to stop when the control bails are released. Ensure that the control and brake function properly before each use of the mower.

Disengage the self-propel mechanism or drive clutch (self-propelled models) before starting the engine.

Before using, always visually inspect the mower to ensure that the blades, blade fasteners, and cutter assembly are not worn or damaged. Replace worn or damaged blades and fasteners in sets to preserve balance.

While Operating

Do not run the engine indoors.

Start the engine carefully, according to instructions and with your feet well away from the blade.

Always maintain secure footing. Keep a firm grip on the handle and walk; never run. Never operate the mower in wet grass. Mow only in daylight or in good artificial light.

Mow across the face of slopes; never up and down. Use extreme caution when changing direction on slopes. Do not mow excessively steep slopes. Wear skid resistant shoes on slopes.

Always wear safety glasses or eye shields during operation to protect your eyes from foreign objects that may be thrown from the mower. Wearing of hearing protection, protective gloves, and a safety helmet is advisable.

Keep face, hands, and feet away from the mower housing and cutter blade when the engine is running. The blade can cause injury to hands and feet. Stay behind the handle until the engine stops.

Use extreme caution when reversing or pulling the mower toward you.

Since the blade rotates for a few seconds after the control bar is released, stay behind the handle until all moving parts stop.

After striking a foreign object or if mower vibrates abnormally, stop the engine and remove the wire from the spark plug. Check the mower for damage and make all repairs before using it again. If major repairs are ever needed or if assistance is desired, contact your local Authorized Toro Service Dealer.

Stop the engine and wait for all moving parts to stop before adjusting the height-of-cut.

Stop the blade when pushing the mower over dirt or gravel driveways.

Stop the engine before leaving the operator's position behind the handle. Disconnect the wire from the spark plug if the mower will be unattended.

Do not touch the engine while it is running or shortly after it is stopped because it will be hot enough to cause a burn.

Refuel only when the engine is cool.

If the mower must be lifted to be transported, turn off the engine and stay behind the handle until all moving parts stop. Disconnect the spark plug wire and allow the engine to cool.

Maintenance and Storage

Perform all maintenance procedures prescribed in this manual. If major repairs are ever needed or if assistance is desired, contact your Authorized Toro Service Dealer.

Before the mower is cleaned, inspected, serviced, or adjusted, stop the engine and disconnect the wire from the spark plug. Keep the wire away from the plug to prevent accidental starting.

To ensure that the mower is in safe operating condition, frequently check and keep all nuts, bolts, and screws tight. Ensure that the blade bolt is tightened to 50 ft±lb (68 N m

When servicing the blade, refer to the Maintaining the Blade section, page 13. for correct installation and servicing procedures.

To reduce fire hazard, keep the engine free of excessive grease, grass, leaves, and accumulations of dirt.

Allow the engine to cool before storing the mower in any enclosure. Do not store the mower with gasoline in the fuel tank near any open flame, or where gasoline fumes may be ignited by a spark.

Do not overspeed the engine by changing the governor settings.

At the time of manufacture, the mower conformed to the safety standards in effect for rotary mowers. For best performance and continued safety certification of the mower, use genuine Toro replacement parts and accessories.

Before Starting

Oil

Initially, the crankcase must be filled with 20 ounces (0.6 liters) of SAE 30 oil; 10W-30 oil may be substituted

if SAE 30 is not available. Use any high quality detergent oil having the American Petroleum Institute (API) ªservice classificationºÐSF, SG, SH or SJ.

Before each use, ensure that the oil level is between the FULL and ADD marks on the dipstick (Fig. 4). Add oil if the level is low.

1.Position the mower on a level surface and clean around the dipstick (Fig. 4).

2.Remove the dipstick by rotating the cap counterclockwise 1/4 turn.

3.Wipe the dipstick clean.

4.Insert the dipstick into the filler neck and rotate the cap clockwise 1/4 turn.

5.Remove the dipstick and check the level of the oil on the side of the dipstick with the FULL and ADD marks (Fig. 4).

Figure 4

1. Dipstick

6.If the level is low, add enough oil to raise the level to the FULL mark on the dipstick.

IMPORTANT: Do not fill above the FULL mark because the engine could be damaged when started. Pour the oil slowly.

Gasoline

DANGER

POTENTIAL HAZARD

In certain conditions gasoline is extremely flammable and highly explosive.

WHAT CAN HAPPEN

A fire or explosion from gasoline can burn you and others and cause property damage.

HOW TO AVOID THE HAZARD

Use a funnel and fill the fuel tank outdoors, in an open area, 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 1/4º to 1/2º (6 mm to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

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

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

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

Toro 20022, 20023, 20025, 20027, 20029 Operator's Manual

DANGER

POTENTIAL HAZARD

When fueling, under certain circumstances, a static charge can develop, igniting the gasoline.

WHAT CAN HAPPEN

A fire or explosion from gasoline can burn you and others and cause property damage.

HOW TO AVOID THE HAZARD

Always place gasoline containers on the ground 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 gas±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, rather than from a gasoline dispenser nozzle.

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

Do not use gasoline that has been stored from one season to the next. Use fresh, clean, unleaded regular grade gasoline. Unleaded gasoline burns cleaner, extends engine life, and promotes good starting. Leaded gasoline can be used if unleaded is not available.

Toro also recommends that Toro Stabilizer/Conditioner be used regularly during operation and storage. Toro Stabilizer/Conditioner cleans the engine during operation and prevents gum-like varnish deposits from forming during periods of storage.

3.Using unleaded gasoline, fill the fuel tank to within 1/4º to 1/2º (6 to 13 mm) from top of tank, not into filler neck.

IMPORTANT: Do not fill the tank more than 1/4º 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 fuel.

IMPORTANT: Do not mix oil with the gasoline. Never use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, or white gas because the fuel system could be damaged.

Do not use fuel additives other than those manufactured for fuel stabilization during storage, such as Toro Stabilizer/Conditioner. Toro Stabilizer/Conditioner is a petroleum distillate based product. Toro does not recommend stabilizers with an alcohol base such as ethanol, methanol, or isopropyl. Do not use additives to enhance the power or performance of the engine.

5. Connect the spark plug wire (Fig. 5).

Operation

Starting the Engine

1.Push the primer three times (five times if you have model 20061 or the temperature is 13_C/55_F or below), waiting 2 seconds between each push (Fig. 7).

IMPORTANT: Do not use the primer to restart a warm engine.

Note: If the engine fails to start after three (3) pulls, repeat steps 1±3.

Stopping the Engine

Release the blade control bail. Both the engine and blade will stop. See your dealer immediately if they do not.

Self±propel Drive

To operate the self-propel drive, simply walk forward with your hands on the upper handle. As you move forward, the upper handle will slide toward the mower, activating the self±propel drive. The faster you walk, the farther the handle will slide and the faster the mower will propel (Fig. 9).

Note: The mower propels at the maximum speed when the upper handle is pushed as far forward as possible.

To slow down or stop, simply slow your walking speed or stop (Fig. 9). If, when backing up after self±propelling, the mower does not roll backward freely, nudge the mower forward about an inch without engaging the self±propel drive, then pull the mower backward.

Adjusting the Cutting Height

Each wheel is adjusted individually with a wheel height adjustment lever. Cutting heights are 1, 1-1/2, 2, 2-1/2, 3 and 3-1/2 inches (25, 38, 51, 64, 74 and 86 mm).

DANGER

POTENTIAL HAZARD

Adjusting the height-of-cut levers could bring your hands into contact with the moving blade.

WHAT CAN HAPPEN

Contact with a rotating blade can cause serious injury.

HOW TO AVOID THE HAZARD

Stop the engine and wait for all movement to stop before adjusting the cutting height.

Do not put your fingers under the mower housing when adjusting the height-of-cut.

1.To change the cutting height, pull the adjusting lever toward the wheel and move it to the desired position (Fig. 10).

Operating Tips

General Tips

Review the safety instructions and read this manual carefully before operating the mower.

Clear the area of sticks, stones, wire, branches, and other debris which could be picked up or hit by the blade and become thrown objects.

Keep everyone, especially children and pets, away from the area of operation.

Avoid striking trees, walls, curbs, or other solid objects. Never deliberately mow over any object.

If an object is struck, or the mower starts to vibrate, immediately stop the engine, disconnect the spark plug wire, and examine the mower for damage.
