Safety

This machine meets or exceeds the

safety specifications of the American

National Standards Institute

B71.1-2003 in effect at the time of

production. However, improper use or

maintenance by the operator or owner

can result in injury. To reduce the

potential for injury, comply with these

safety instructions and always pay

attention to the safety alert symbol,

which means CAUTION, WARNING, or

DANGER-"personal safety instruction."

Failure to comply with the instruction

may result in personal injury or death.

Safe Operating Practices

The following instructions are from ANSI

standard B71.1-2003.

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.

•Do not place hands or feet near rotating

parts or under the machine. Keep clear of

the discharge opening at all times.

•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 up.

•Be aware of the mower discharge

direction and do not point it at anyone.

Avoid discharging material against a wall

or obstruction. Material may ricochet back

toward the operator. Stop the blades

when crossing gravel surfaces.

•Do not operate the mower without either

the entire grass collection system or the

discharge deflector in place.

•Be alert, slow down and use caution when

making turns. Look behind and to the side

before changing directions.

•Never leave a running machine

unattended. Always turn off blades,

engage parking brake, stop engine, and

remove key before dismounting.

•Turn off blades when not mowing. Stop

the engine, wait for all parts to come to a

complete stop, engage parking brake, and

remove key before cleaning the machine,

removing the grass or unclogging the

deflector.

•Operate the machine 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.

•Use extra care when loading or unloading

the machine into a trailer or truck.

•Always wear eye protection when

operating the 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.

•Always follow the recommendations for

wheel weights or counterweights.

Slope Operation

Slopes are a major factor related to loss of

control and tip-over accidents, which can

result in severe injury or death. Operation on

all slopes requires extra caution. If you

cannot back up the slope or if you feel uneasy

on it, do not mow it.

•Do not mow slopes greater than

15 degrees.

•Watch for ditches, holes, rocks, dips, and

rises that change the operating angle, as

rough terrain could overturn the machine.

•Choose a low ground speed so you will

not have to stop while operating on a

slope.

•Do not mow slopes when grass is wet.

Slippery conditions reduce traction and

could cause sliding and loss of control.

•Reduce speed and use extreme caution

on slopes.

•Do not make sudden turns or rapid speed

changes.

•Remove or mark obstacles such as rocks,

tree limbs, etc. from the mowing area. Tall

grass can hide obstacles.

•Avoid sudden starts when mowing uphill

because the mower may tip backwards.

•Be aware that loss of traction may occur

going downhill. Weight transfer to the front

wheels may cause drive wheels to slip

and cause loss of braking and steering.

•Always avoid sudden starting or stopping

on a slope. If tires lose traction, disengage

the blades and proceed slowly off the

slope.

•Use extreme care with grass collection

systems or other attachments. These can

change the stability of the machine and

cause loss of control.

•Do not try to stabilize the machine by

putting your foot on the ground.

•Do not mow near drop-offs, ditches, steep

banks or water. Wheels dropping over

edges can cause rollovers, which may

result in serious injury, death or drowning.

•Use a walk behind mower and/or a hand

trimmer near drop-offs, ditches, steep

banks or water.

Children

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.

•Keep children out of the mowing area and

under the watchful care of another

responsible adult, not the operator.

•Be alert and turn the machine off if

children enter the area.

•Before and while backing or changing

direction, look behind, down, and side-to-

side 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.

•Children who have been given rides in the

past may suddenly appear in the mowing

area for another ride and be run over or

backed over by the mower.

•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.

Towing

•This machine does not make any

provisions for towing.

Service

Safe Handling of Gasoline:

To avoid personal injury or property damage,

use extra care when handling gasoline and

other fuels. They are flammable and the

vapors are explosive.

•Extinguish all cigarettes, cigars, pipes and

other sources of ignition.

•Use only an approved container.

•Never remove the gas cap or add fuel

when the engine is running. Allow the

engine to cool before refueling.

•Never refuel the machine indoors.

•Never store the machine or fuel container

inside where there is an open flame, such

as near a water heater or furnace.

•Never fill containers inside a vehicle or on

a truck or trailer with a plastic liner.

Always place containers on the ground

away from your vehicle before filling.

•Remove gas-powered equipment from the

truck or trailer and refuel it on the ground.

If this is not possible, then refuel such

equipment with a portable container,

rather than from a gasoline dispenser

nozzle.

•Keep the nozzle in contact with the rim of

the fuel tank or container opening at all

times until the fueling is complete. Do not

use a nozzle lock-open device.

•If fuel is spilled on clothing, change

clothing immediately.

•Never overfill the fuel tank. Replace gas

cap and tighten securely.

General Service:

•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 and fuel soaked debris. Allow the

machine to cool before storing.

•Stop and inspect the equipment if you

strike an object. Repair, if necessary,

before restarting.

•Never make any adjustments or repairs

with the engine running.

•Grass collection system 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 manufacturers’

recommended parts, when necessary.

•Mower blades are sharp and can cut.

Wrap the blades or wear gloves, and use

extra caution when servicing them.

•Check for proper brake operation

frequently. Adjust and service as

required.

•Maintain or replace safety and instruction

decals as necessary.

•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.

•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, wait for all moving

parts to stop, engage parking brake,

disconnect spark plug wire(s) and

remove key before performing any

service, repairs, maintenance or

adjustments.

•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 Toro approved attachments.

Warranty may be voided if used with

unapproved attachments.

•If loading the machine onto a trailer or

truck, use a single, full-width ramp only.

The ramp angle should not exceed

15 degrees.

Note: The left and right sides of the machine

are determined while sitting in the seat in the

normal operating position.
