Safety
Improperly using or maintaining this lawn mower can
result in injury. To reduce the potential for injury,
comply with these safety instructions.
Toro designed and tested this lawn mower for to offer
reasonably safe service; however, failure to comply with the
following instructions may result in personal injury.
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.
Warning
Engine exhaust contains carbon monoxide, an
odorless, deadly poison that can kill you.
Do not run the engine indoors or in an enclosed
area.
To ensure maximum safety, best performance, and to
gain knowledge of the product, it is essential that you
and any other operator of the lawn mower read and
understand the contents of this manual before the
engine is ever started. Pay particular attention to the
safety alert symbol which means caution, warning,
or danger — “personal safety instruction.” Read and
understand the instruction because it has to do with
safety. Failure to comply with the instruction may result
in personal injury.
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.
• 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.
3
– Refuel outdoors only and do not smoke while
refuelling.
• Disengage all blade and drive clutches before starting
the engine.
– 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.
• 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.
• 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.
4
• 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.
• 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.
• 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 22 ounces (0.65 liters) of oil. Use
only high-quality, SAE 30 or SAE 10W30 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. 6).
To add oil:
1. Move the lawn mower to a level surface.
2. Clean around the dipstick (Fig. 6).
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. 6).
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,
including oxygenated or reformulated 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.
