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 allow adults unfamiliar with these instructions to operate the lawn mower.
• 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.
• 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.
3
• 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.
• Stop the engine and disconnect the spark-plug wire:
– 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.
• Check the grass catcher frequently for wear or deterioration.
• Replace worn or damaged parts.
• Use extra care when handling gasoline; gasoline vapors are explosive.
4
• 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.

Before Starting
Filling the Crankcase with Oil
The crankcase can hold 22 ounces (0.65 liters) of oil. Use only high-quality SAE 30 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).
1
Note: To ensure an accurate oil level reading, you must fully install the dipstick.
6.
Read the oil level 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 oil fill tube 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 can 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. Using unleaded gasoline results in fewer combustion deposits and longer spark plug 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.

2.
Clean around the dipstick (Fig. 7).
3.
Remove the dipstick from the oil fill tube 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.

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.
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 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.
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.

4.
Install the fuel tank cap and wipe up any spilled gasoline.
Reviewing the Maintenance
Schedule
Review the Recommended Maintenance Schedule on page 12. You may need to perform one or more additional procedures before or soon after you begin operating the lawn mower.
Operation
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 and the control bar operate properly. When you release the control bar, the engine and the self-propel drive should stop. If they do not, contact an Authorized Service Dealer.

Figure 11
1. The ground speed increases as you move the control bar toward the handle.
You can vary the ground speed by increasing or decreasing distance between control bar and handle (Fig. 11) as follows:
• Lower control bar to slow the mower. If you lower control bar too far, the mower stops self-propelling.
• Squeeze the control bar closer to the handle to increase the ground speed.
• Move the ground speed control to the (Neutral) position when using the mower for trimming.
Note: The drive wheels come with freewheeling clutches that enable you to pull the lawn mower rearward more easily when you disengage the wheel drive. To disengage the clutches, push the lawn mower forward at least 1 inch
(2.5 cm) after stopping the wheel drive operation.
Adjusting the Cutting Height
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.
Disconnect the wire from the spark plug (Fig. 10).

Figure 14
Mowing with the Grass Bag
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.
10
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 and hold it up.
3.
Grasp the handle on the grass bag and lift it off of the lawn mower.
4.
Close the discharge door.
Note: When removing the grass bag, the bag ramp removes any clippings that may plug the discharge opening. If the discharge opening is still plugged, disconnect the wire from the spark plug and remove the clippings with a stick.
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.
Operating Tips
• 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
Wet grass or leaves can cause you to slip and contact the blade, resulting in serious injury.
Mow only in dry conditions.
• Clean under the housing after each mowing. See
Cleaning under the Housing on page 13.
• 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.
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
2 inch (51 mm), 2-1/2 inch (64 mm), or 3 inch (76 mm) 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.
11
• 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 2 inches (51 mm) and the rear wheels at
2-1/2 inches (64 mm).
• 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 housing.
• 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.
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.
