Safety
Safe Operation Practices for
Ride-on (riding) Rotary
Lawnmower Machines
This machine meets or exceeds European Standards 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
Write the product model and serial numbers in the space
below:
Model No.
Serial No.
This manual identifies potential hazards and has special
safety messages that help you and others avoid personal
injury and even death. Danger, Warning, and Caution are
signal words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.
Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
The following instructions are from the CEN standard EN
836:1997.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Training
• Read the instructions carefully. Be familiar with the
controls and the proper use of the equipment.
• Never allow children or people unfamiliar with these
instructions to use the lawnmower. Local regulations
can restrict the age of the operator.
• Never mow while people, especially children, or pets
are nearby.
• Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people or their
property.
• Do not carry passengers.
• All drivers should seek and obtain professional and
practical instruction. Such instruction should
emphasize:
– the need for care and concentration when working
with ride-on machines;
– control of a ride-on machine sliding on a slope will
not be regained by the application of the control
levers. The main reasons for loss of control are:
• insufficient wheel grip, especially on wet grass;
• being driven too fast;
• inadequate braking;
• the type of machine is unsuitable for its task;
3
• lack of awareness of the effect of ground
conditions, especially slopes;
• incorrect hitching and load distribution.
Preparation
• While mowing, always wear substantial footwear and
long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
• Thoroughly inspect the area where the equipment is to
be used and remove all objects which may be thrown by
the machine.
• Warning—Fuel is highly flammable.
– 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 fuel while the engine
is running or when the engine is hot.
– If fuel is spilled, do not attempt to start the engine
but move the machine away from the area of
spillage and avoid creating any source of ignition
until fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
• Replace faulty silencers.
• Before using, always visually inspect to see that the
blades, blade bolts and cutter assembly are not worn or
damaged. Replace worn or damaged blades and bolts in
sets to preserve balance.
• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
– use slow speeds on slopes and during tight turns;
– stay alert for humps and hollows and other hidden
hazards;
• Use care when pulling loads or using heavy equipment.
– Use only approved drawbar hitch points.
– Limit loads to those you can safely control.
– Do not turn sharply. Use care when reversing.
• Watch out for traffic when crossing or near roadways.
• Stop the blades rotating before crossing surfaces other
than grass.
• When using any attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while in operation.
• Never operate the machine with damaged guards or
without safety protective devices in place.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at excessive
speed can increase the hazard of personal injury.
• Before leaving the operator’s position:
– disengage the power take-off and lower the
attachments;
– change into neutral and set the parking brake;
– stop the engine and remove the key.
• Disengage drive to attachments, stop the engine, and
disconnect the spark plug wire(s) or remove the ignition
key
– before clearing blockages or unclogging chute;
– before checking, cleaning or working on the
lawnmower;
Operation
• Be alert, slow down and use caution when making
turns. Look behind and to the side before changing
directions.
• 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.
• Before attempting to start the engine, disengage all
blade attachment clutches and shift into neutral.
• Do not use on slopes greater than 12–1/2 degrees.
• Remember there is no such thing as a safe slope. Travel
on grass slopes requires particular care. To guard
against overturning:
– do not stop or start suddenly when on a slope;
– after striking a foreign object. Inspect the
lawnmower for damage and make repairs before
restarting and operating the equipment;
– if the machine starts to vibrate abnormally (check
immediately).
• Disengage drive to attachments when transporting or
not in use.
• Stop the engine and disengage drive to attachment
– before refuelling;
– before removing the grass catcher;
– before making height adjustment unless adjustment
can be made from the operator’s position.
• Reduce the throttle setting during engine run-out and, if
the engine is provided with a shut-off valve, turn the
fuel off at the conclusion of mowing.
4
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Never store the equipment with fuel in the tank inside a
building where fumes can reach an open flame or spark.
• Allow the engine to cool before storing in any
enclosure.
• To reduce the fire hazard, keep the engine, silencer,
battery compartment and fuel storage area free of grass,
leaves, or excessive grease.
• Check the grass catcher frequently for wear or
deterioration.
• Replace worn or damaged parts for safety.
• If the fuel tank has to be drained, this should be done
outdoors.
• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
• When machine is to be parked, stored or left
unattended, lower the cutting means unless a positive
mechanical lock is used.
• 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.
• Do not mow slopes when grass is wet. Slippery
conditions reduce traction and could cause sliding and
loss of control.
• Do not make sudden turns or rapid speed changes.
• Use a walk behind mower and/or a hand trimmer near
drop–offs, ditches, steep banks or water.
• Reduce speed and use extreme caution on slopes.
• Remove or mark obstacles such as rocks, tree limbs,
etc. from the mowing area. Tall grass can hide
obstacles.
• Watch for ditches, holes, rocks, dips, and rises that
change the operating angle, as rough terrain could
overturn the machine.
• 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.
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 CEN standard.
• 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.
• 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 Toro replacement parts to ensure that
original standards are maintained.
• Use only Toro-approved attachments. Warranty may be
voided if used with unapproved attachments.
• Always avoid sudden starting or stopping on a slope. If
tires lose traction, disengage the blades and proceed
slowly off the slope.
• Follow the manufacturer’s recommendations for wheel
weights or counterweights to improve stability.
• Use extreme care with grass catchers or other
attachments. These can change the stability of the
machine and cause loss of control.
Slope Operation
• Do not mow slopes greater than 12-1/2 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.
• Never fill the fuel tank inside an enclosed trailer.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 inch (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 inch (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.
11
Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Think Safety First
Controls
Become familiar with all of the controls (Fig. 3 and 4)
before you start the engine and operate the machine.

3
Please carefully read all of the safety instructions and
decals in the safety section. Knowing this information
could help you, your family, pets or bystanders avoid
injury.
Danger
Mowing on wet grass or steep slopes can cause
sliding and loss of control.
Wheels dropping over edges can cause rollovers,
which may result in serious injury, death or
drowning.
To avoid loss of control and possibility of rollover:
• Do not mow near drop–offs or near water.
• Do not mow slopes greater than 12.5 degrees.
• Reduce speed and use extreme caution on slopes.
• Avoid sudden turns or rapid speed changes.
