Safe Operating Practices
The following instructions are from ANSI standard
B71.1—1998.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
General Operation
• Read, understand, and follow all instructions in the
operator’s manual and on the machine before starting.
• Allow only responsible adults who are familiar with the
instructions to operate the machine.
• Clear the area of objects such as rocks, toys, wire, etc.,
which could be picked up and thrown by the blade.
• Be sure the area is clear of other people before mowing.
Stop the machine if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely necessary.
Always look down and behind before and while
backing.
• Be aware of the mower discharge direction and do not
point it at anyone. Do not operate the mower without
either the entire grass catcher or the guard in place.
• Slow down before turning.
• Never leave a running machine unattended. Always turn
off blades, set parking brake, stop engine, and remove
key before dismounting.
• Turn off blades when not mowing.
• Stop the engine before removing the grass catcher or
unclogging the chute.
• Mow only in daylight or good artificial light.
• Do not operate the machine while under the influence
of alcohol or drugs.
• Watch for traffic when operating near or crossing
roadways.
3
• Use extra care when loading or unloading the machine
into a trailer or truck.
• Keep children out of the mowing area and under the
watchful care of another responsible adult.
• Always wear safety goggles or safety glasses with side
shields when operating mower.
• Data indicates that operators, age 60 years and above,
are involved in a large percentage of riding
mower–related injuries. These operators should
evaluate their ability to operate the riding mower safely
enough to protect themselves and others from serious
injury.
Slope Operation
Slopes are a major factor related to loss-of-control and
tip-over accidents, which can result in severe injury or
death. All slopes require extra caution. If you cannot back
up the slope or if you feel uneasy on it, do not mow it.
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts or bumps. Uneven terrain could
overturn the machine. Tall grass can hide obstacles.
• Use slow speed. Choose a low gear so that you will not
have to stop or shift while on the slope.
• Follow Toro’s recommendations for wheel weight or
counterweights to improve stability.
• Use extra care with grass catchers or other attachments.
These can change the stability of the machine.
• Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction.
• Avoid starting or stopping on a slope. If tires lose
traction, disengage the blades and proceed slowly
straight down the slope.
• Do not turn on slopes unless necessary, and then, turn
slowly and gradually downhill, if possible.
• Do not mow near drop-offs, ditches, or embankments.
The machine could suddenly turn over if a wheel goes
over the edge of a cliff or ditch, or if an edge caves in.
• Do not mow on wet grass. Reduced traction could cause
sliding.
• Do not try to stabilize the machine by putting your foot
on the ground.
• Do not use a grass catcher on steep slopes.
Children
• Be alert and turn the machine off if children enter the
area.
• Before and while backing, look behind and down for
small children.
• Never carry children, even with the blades off. They
may fall off and be seriously injured or interfere with
safe machine operation.
• Never allow children to operate the machine.
• Use extra care when approaching blind corners, shrubs,
trees, the end of a fence or other objects that may
obscure vision.
Service
• Use extra care when handling gasoline and other fuels.
They are flammable and vapors are explosive.
A. Use only an approved container.
B. Never remove the gas cap or add fuel when the
engine is running. Allow the engine to cool before
refueling. Do not smoke.
C. Never refuel the machine indoors.
D. Never store the machine or fuel container inside
where there is an open flame, such as near a water
heater or furnace.
• Never run a machine inside a closed area.
• Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good condition.
• Never tamper with safety devices. Check their proper
operation regularly.
• Keep the machine free of grass, leaves, or other debris
build-up. Clean up oil or fuel spillage. Allow the
machine to cool before storing.
• Stop and inspect the equipment if you strike an object.
Repair, if necessary, before restarting.
• Grass catcher components are subject to wear, damage
and deterioration, which could expose moving parts or
allow objects to be thrown. Frequently check
components and replace with manufacturer’s
recommended parts, when necessary.
• Mower blades are sharp and can cut. Wrap the blade(s)
or wear gloves, and use extra caution when servicing
them.
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
machine and the mowing activity. Never assume that
children will remain where you last saw them.
• Use only genuine Toro replacement parts to ensure that
original standards are maintained.

Toro Riding Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI standards.
Warning
Engine exhaust contains carbon monoxide, which
is an odorless, deadly poison that can kill you.
Do not run engine indoors or in an enclosed area.
• Stop the engine, disconnect spark plug wire(s) and
remove key before performing any service, repairs,
maintenance or adjustments.
• Slow down before turning. Sharp turns on any terrain
may cause loss of control.
• Never leave a running machine unattended. Always turn
off blades, set parking brake, stop engine, and remove
the ignition key before dismounting.
• Keep hands, feet, hair, and loose clothing away from
attachment discharge area, underside of mower and any
moving parts while engine is running.
• Do not touch equipment or attachment parts which may
be hot from operation. Allow to cool before attempting
to maintain, adjust or service.
• Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes, and clothing. Protect your face,
eyes, and clothing when working with a battery.
• Battery gases can explode. Keep cigarettes, sparks and
flames away from battery.
• Use only genuine replacement parts to ensure that
original standards are maintained.
• Use only Toro approved attachments. Warranty may be
voided if used with unapproved attachments.
• Do not mow across slopes exceeding 5 degrees.
• Do not mow down slopes exceeding 15 degrees.
• Do not mow up slopes exceeding 10 degrees.
• If a steep slope must be ascended, back up the hill, and
drive forward down the hill, keeping the machine in
gear.
• Avoid turning on slopes. If you must turn, turn slowly
and gradually downhill, if possible.
• Do not use a grass catcher on steep slopes. Heavy grass
bags could cause loss of control or overturn the
machine.
• If loading the machine onto a trailer or truck, use a
single, full-width ramp only. The ramp angle should not
exceed 15 degrees.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for automotive
use (87 pump octane minimum). Leaded regular gasoline
may be used if unleaded regular is not available.
Important Never use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol
because the fuel system could be damaged. Do not mix oil
with gasoline.
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,
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
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.
• 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.
Warning
Gasoline is harmful or fatal if swallowed.
Long–term exposure to vapors can cause serious
injury and illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of
varnish deposits in the fuel system, use fuel stabilizer at all
times.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around the fuel tank cap and remove the cap. Add
unleaded regular 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 space in the tank allows gasoline to
expand. Do not fill the fuel tank completely full.
3. Install the fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Checking the Engine Oil Level
Before you start the engine and use the machine, check the
oil level in the engine crankcase; refer to Checking the Oil
Level, page 21.
