General Lawn Mower Safety

The following instructions have been adapted from the ANSI/OPEI standard B71.1—1998 and ISO standard 5395:1990(E). Information or terminology specific to Toro lawn mowers is enclosed in parenthesis.

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

Training

• Read this operator’s manual carefully. Be thoroughly

familiar with the controls and the proper use of the lawn mower before starting it.

• Never allow children to operate the lawn mower. Local

regulations may restrict the age of the operator.

• Never mow while people (especially children) or pets

are nearby. Stop the lawn mower if anyone enters the area.

• Tragic accidents can occur if the operator is not alert to

the presence of children. Children are often attracted to the lawn mower and the mowing activity. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and under the

watchful care of a responsible adult.

• Be alert and turn the lawn mower off if children enter

the area.

• Use extra care when approaching blind corners, shrubs,

trees, or other objects that may obscure vision.

• Keep in mind that the operator or user is responsible for

accidents or hazards occurring to other people or their property.

• See the manufacturer’s instructions for proper operation

and installation of accessories. Use only the accessories that are approved by the manufacturer.

Preparation

• Thoroughly inspect the area where you will use the

lawn mower, and remove all stones, sticks, wires, bones, and other foreign objects.

• While mowing, always wear substantial footwear and

long trousers.

• Do not operate the lawn mower when barefoot or

wearing open sandals.

• Always wear safety goggles or safety glasses with side

shields when operating the lawn mower.

• Warning: Gasoline is highly flammable. Take the

following precautions: – Store fuel in containers specifically designed for this

purpose.

– Refuel outdoors only and do not smoke while

refuelling.

– Add fuel before starting the engine. Never remove

the cap of the fuel tank or add gasoline while the engine is running or when the engine is hot.

– If gasoline is spilled, do not attempt to start the

engine. Move the lawn mower away from the area of spillage to avoid creating any source of ignition

until the gasoline vapors have dissipated. – Replace all fuel tank and container caps securely. – If you must drain the fuel from the fuel tank, do it

outdoors.

• Replace faulty mufflers.

• Stop the engine and disconnect the spark-plug wire:

• Before using, always visually inspect the blades, blade

bolts, and cutter assembly for wear or damage. Replace worn or damaged blades and bolts in sets to preserve balance.

• On multibladed lawn mowers, use care as rotating one

blade can cause the other blades to rotate.

Operation

• Do not operate the engine in a confined space where

dangerous carbon monoxide fumes can collect.

• Mow only in daylight or in good artificial light.

• Always be sure of your footing on slopes.

• Walk; never run.

• Keep a firm hold on the handle.

• For wheeled rotary lawn mowers, mow across the face

of slopes, never up and down.

• Exercise extreme caution when changing the direction

on slopes.

• Do not mow excessively steep slopes.

• Use extreme caution when reversing or pulling the lawn

mower toward you.

• Before and while moving backward, look behind and

down for small children.

• Stop the blade(s) if you must tilt the lawn mower for

transportation when crossing surfaces other than grass and when transporting the lawn mower to and from the area to be mowed.

• Never operate the lawn mower with damaged or

missing guards or shields, or without safety devices (such as deflectors and grass catchers) in place.

• Do not change the speed settings on the engine.

• Disengage all blade and drive clutches before starting

the engine.

• Start the engine carefully according to instructions and

with feet well away from the blade(s).

• Do not tilt the lawn mower when starting the engine,

unless you must tilt the lawn mower to start it. In this case, do not tilt it more than absolutely necessary and lift only the part which is away from the operator.

• Do not start the engine when standing in front of the

discharge chute.

• Do not put your hands or feet near or under rotating

parts. Keep clear of the discharge opening at all times.

• Never pick up or carry a lawn mower while the engine

is running.

– before clearing blockages or unclogging the chute; – before checking, cleaning, or working on the lawn

mower;

– after striking a foreign object. Inspect the lawn

mower for damage and make repairs before starting and operating the lawn mower; and

– if the lawn mower starts to vibrate abnormally

(check it immediately).

• Stop the engine:

– whenever you leave the lawn mower; and – before refuelling.

• Reduce the throttle setting during engine run-out and, if

the engine has a shutoff valve, turn the fuel off after mowing.

• Stop the blade(s) when crossing gravel drives, walks, or

roads.

• Shut the engine off and wait until the blade comes to a

complete stop before removing the grass catcher.

• Do not operate the lawn mower while under the

influence of alcohol or drugs.

• If the lawn mower should start to vibrate abnormally,

stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

Slopes are a major factor related to slip and fall accidents which can result in a severe injury. If you feel uneasy on a slope, do not mow it.

• Watch for holes, ruts, or bumps. Tall grass can hide

obstacles.

• Do not mow near drop-offs, ditches, or embankments.

You could lose your footing or balance.

• Do not mow on wet grass. Reduced footing could cause

slipping.

Maintenance and Storage

• Keep all nuts, bolts (especially blade attachment bolts),

and screws tight to ensure that the lawn mower is in safe working condition.

• Never store the lawn mower with gasoline in the tank

inside a building where fumes may reach an open flame or spark.

• Allow the engine to cool before storing the lawn mower

in any enclosure.

• To reduce the fire hazard, keep the engine, muffler,

battery compartment, and gasoline storage area free of grass, leaves, or excessive grease.

Page 5

• Check the grass catcher frequently for wear or

deterioration.

• Replace worn or damaged parts.

• Use extra care when handling gasoline; gasoline vapors

are explosive.

• Never tamper with safety devices. Check their proper

operation regularly.

• Keep the lawn mower free of grass, leaves, or other

debris buildup. Clean up any oil or fuel that spills.

• Stop and inspect the lawn mower if you strike an object.

Repair the lawn mower, if necessary, before starting the engine.

• Never attempt to make wheel height adjustments while

the engine is running.

• Grass catcher components are subject to wear, damage,

and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check the components and replace them with the manufacturer’s recommended parts when necessary.

• Lawn mower blades are sharp and can cut. Wrap the

blade(s) or wear gloves, and use extra caution when servicing them.

• Do not change the speed settings on the engine.

• If you must drain the fuel from the fuel tank, do it

outdoors.

• To ensure the best performance and safety, purchase

only genuine Toro replacement parts and accessories.

• Maintain or replace safety and instruction decals when

necessary.

Before Starting

Filling the Crankcase with Oil

The crankcase can hold 20 ounces (0.59 liters) of oil. Use only high-quality, SAE 30 weight detergent oil that has the American Petroleum Institute (API) service classification SF, SG, SH, or SJ.

Before each use, ensure that the oil level is between the Add and the Full marks on the dipstick (Fig. 7).

7. If the oil level reading 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.

8. 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. Unleaded gasoline burns cleaner, extends engine life, and promotes good starting. 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.

To add oil:

1. Move the lawn mower to a level surface.

2. Clean around the dipstick (Fig. 7).

3. Remove the dipstick by rotating the cap

counterclockwise and pulling it out.

4. Wipe the dipstick clean with a clean cloth.

5. Fully insert the dipstick into the filler neck, then remove

it.

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

6. Read the oil level on the dipstick (Fig. 7).

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 in. (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.

Page 9

Danger

Operation

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 round.

• 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.

Note: Determine the left and right sides of the machine from the normal operating position.

Each time before you mow, ensure that the self-propel drive (self-propel model only) and the blade control bail operate properly. When you release the blade control bail, the engine and the self-propel drive should stop. If they do not, contact an Authorized Service Dealer.

Controls

The starter handle and the blade control bail are on the upper handle as shown in Figure 8.

3. Starter handle

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. 7).

2. Remove the cap from the tank.

3. Fill the fuel tank with unleaded gasoline to within 1/4 to 1/2 in. (6 to 13 mm) from the top of the tank. Do not fill into the filler neck.

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

gasoline.

Reviewing the Maintenance Schedule

Review the Recommended Maintenance Schedule on page 14. You may need to perform one or more additional procedures before or soon after you begin operating the lawn mower.

Starting the Engine

1. Connect the wire to the spark plug (Fig. 7).

2. Push in the primer 3 times, waiting one second between

each push (Fig. 9).

13441

Figure 9

1. Primer

Note: If the temperature is 55F (13C) or below, push in the primer 5 times, waiting one second between each push.

Note: Do not use the primer to start a warm engine after a brief shutdown. However, cool weather may require you to prime the engine again.

Page 10

3. Hold the blade control bail against the upper handle

(Fig. 10).

Adjusting the Cutting Height

The SmartWheel has 2 cutting scales: Sparse/Normal and Lush—to ensure the best cutting height setting in any mowing condition (Fig. 12). Use the Sparse/Normal scale during the warm summer season for the majority of your mowing. The Lush scale is for thick, moist, and succulent grass that grows most often in the spring.

Figure 10

1. Blade control bail

2. Upper handle

4. Pull the starter handle lightly until you feel resistance,

then pull it sharply (Fig. 10). Allow the rope return to the handle slowly.

Note: Allow the engine to warm up for at least one minute; longer in cooler temperatures.

Note: If the engine fails to start after 3 attempts, repeat steps 2 through 4.

3. Starter handle

m-4207

Stopping the Engine

Release the blade control bail. Both the engine and the blade should stop. If they do not stop properly, contact your Authorized Service Dealer.

Using the Self-propel Drive

To operate the self-propel drive, simply walk forward with your hands on the upper handle and your elbows at your sides, and the lawn mower will automatically keep pace with you. The faster you walk, the farther the handle will slide and the faster the lawn mower will propel (Fig. 11).

Figure 12

1. Sparse/normal grass cutting scale

Toro recommends the following:

• Cut the grass at the D, E, or F settings or keep the grass between 2 to 3 inches (5.1 to 7.6 cm) high.

• Do not cut below the D setting unless the grass is sparse or it is late fall when grass growth begins to slow down. When you cut long grass, use a higher cutting height setting and walk slower; then cut the grass again at a normal setting. Mowing the grass when it is too long can plug the lawn mower and cause the engine to stall.

Note: The SmartWheel calculates the proper setting to ensure that you cut no more than a third of the grass blade.

2. Lush grass cutting scale

m-4206

Figure 11

To slow down the drive, simply slow your walking speed; to stop the drive, stop walking (Fig. 11).

Note: If, when backing up after self-propelling, the lawn mower does not roll backward freely, nudge the lawn mower forward about an inch without engaging the self-propel drive, then pull the lawn mower backward.

Danger

Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury.

• Stop the engine and wait for all movement to

stop before adjusting the cutting height.

• Do not put fingers under the housing when

adjusting the cutting height.

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

2. Move the lawn mower into the grass; stop moving the

lawn mower when the SmartWheel design on one of the rear wheels is upright (Fig. 12).

Page 11

3. Use the SmartWheel design to compare the tips of the

grass blades to the letters on the wheel. The letter on the SmartWheel that matches the tips of the grass blades is the proper cutting height.

4. Squeeze the cutting height lever toward the wheel and

move it to the corresponding letter on the lawn mower housing (Fig. 13).

Note: For easier adjustment, lift up the housing so that the wheel is off the ground. Do not put your fingers under

the housing when you lift up the lawn mower.

5. Ensure that the pin on the cutting height lever engages

the slot in the housing.

Using the Grass Bag

Occasionally, you may want to use the grass bag for bagging lush grass or collecting leaves.

Installing the Grass Bag

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

2. Ensure that the discharge door handle is fully forward

and that the pin is contacting the catch (Fig. 14).

Operating Tips

Warning

A worn grass bag could allow small stones and other similar debris to be thrown in the operator’s or bystander’s direction and result in serious personal injury or death to the operator or bystanders.

Check the grass bag frequently. If it is damaged, install a new Toro replacement bag.

Cut the grass until the bag is full.

Important Do not overfill the bag.

Removing the Grass Bag

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

2. Raise the discharge door handle and move it forward

until the locking pin contacts the catch (Fig. 14).

3. Grasp the handle at the front and the rear of the bag and

lift the bag off the lawn mower.

4. Gradually tip the bag forward to empty the clippings.

• Review the safety instructions and read this manual

carefully before operating the lawn mower.

• Clear the area of sticks, stones, wire, branches, and

other debris that the blade could hit and throw.

• 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 the lawn mower strikes an object or starts to vibrate,

immediately stop the engine, disconnect the wire from the spark plug, and examine the lawn mower for damage.

• Maintain a sharp blade throughout the cutting season.

Periodically file down nicks on the blade.

• Replace the blade when necessary with an original Toro

replacement blade.

• Mow only dry grass or leaves. Wet grass and leaves

tend to clump on the yard and can cause the lawn mower to plug or the engine to stall.

Warning

5. To install the bag, refer to steps 3 through 5 of Installing

the Grass Bag earlier in this section.

Danger

If the discharge door does not close completely, the lawn mower could throw objects, causing serious personal injury or death.

If you cannot close the discharge door because the grass clippings clog the discharge area, stop the engine, wait for all moving parts to stop, and gently move the discharge door handle back and forth until you can close the discharge door completely. If you still cannot close the discharge door, remove the obstruction with a stick, not your hand.

Wet grass or leaves can cause serious injury if you slip and contact the blade.

Mow only in dry conditions.

• Clean the underside of the lawn mower deck after each

mowing. See Cleaning the Underside of the Lawn Mower Housing on page 15.

• Keep the engine in good running condition.

• Set the engine speed to the fastest position for the best

cutting results.

Warning

Operating a lawn mower with its engine running at a speed greater than the factory setting can cause the lawn mower to throw a part of the blade or engine into the operator’s or bystander’s area and result in serious personal injury or death.

• Do not change the engine speed setting.

• If you suspect the engine speed is faster than

normal, contact an Authorized Service Dealer.

• Clean the air filter frequently. Recycling stirs up more

clippings and dust which clogs the air filter and reduces engine performance.

Page 13

Cutting Grass

• Grass grows at different rates at different times of the

year. In the summer heat, it is best to cut grass at the C, D, or E cutting height settings. Cut only about a third of the grass blade at a time. Do not cut below the 2-inch (51 mm) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.

• When cutting grass over 6 inches (15 cm) tall, first

mow at the highest cutting height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long and the leaves clump on top of the lawn, the lawn mower may plug and cause the engine to stall.

• Alternate the mowing direction. This helps disperse the

clippings over the lawn for even fertilization.

If the finished lawn appearance is unsatisfactory, try one or more of the following:

• Sharpen the blade.

• Walk at a slower pace while mowing.

• Raise the cutting height on your lawn mower.

• Cut the grass more frequently.

• Overlap cutting swaths instead of cutting a full swath

with each pass.

• Set the cutting height on the front wheels one notch

lower than the rear wheels. For example, set the front wheels at the C setting and the rear wheels at the D setting.

Cutting Leaves

• After cutting the lawn, ensure that half of the lawn

shows through the cut leaf cover. You may need to make more than one pass over the leaves.

• For light leaf coverage, set all the wheels at the same

cutting height setting.

• If there are more than 5 inches (12.7 cm) of leaves on

the lawn, set the front cutting height one or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the lawn mower deck.

• Slow down your mowing speed if the lawn mower does

not cut the leaves finely enough.

• If you mow over oak leaves, you can add lime to the

grass in the spring to reduce the acidity of the oak leaves.

Maintaining the Blade

A straight, sharp blade provides the best cutting performance. Regularly inspect and sharpen the blade.

Warning

The blade is sharp; contacting the blade can result in serious personal injury.

Inspecting the Blade

Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (Fig. 26A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the lawn mower. If you notice a slot or wear (Figs. 26B and 26C), replace the blade; refer to Removing the Blade on page 20.

Wear gloves or wrap the sharp edges of the blade with a rag.

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

2. Disconnect the wire from the spark plug (Fig. 7).

Warning

Avoid fuel spills by running the engine dry or removing gasoline with a hand pump; never siphon.
