Safe Operating Practices

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.

Read this manual carefully to learn how to operate and maintain your product correctly. Reading this manual will help you and others avoid personal injury and damage to the product. Although we design, produce and market safe, state-of-the-art products, you are responsible for using the product properly and safely. You are also responsible for training persons, who you allow to use the product, about safe operation.

The warning system in this manual identifies potential hazards and has special safety messages that help you and others avoid personal injury, 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 the recommended precautions are not followed.

Warning signals a hazard that may cause serious injury or death if the recommended precautions are not followed.

Caution signals a hazard that may cause minor or moderate injury if the recommended precautions are not followed.

Two other words are also used to highlight information. Important calls attention to special mechanical information, and Note emphasizes general information worthy of special attention.

Determine the left and right side of the machine from the normal operating position.

Training

• Read the instructions carefully. Be familiar with the

controls and the proper use of the equipment.

• Never allow children to use the lawnmower. Never

allow 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 operators 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 brake. The main reasons for loss of control are:

• insufficient wheel grip;

• being driven too fast;

• inadequate braking;

• the type of machine is unsuitable for its task;

Safety

This machine meets or exceeds the B71.1-1998 specifications of the American National Standards Institute, 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.

• 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.

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.

• Before attempting to start the engine, disengage all

blade attachment clutches and shift into neutral.

• Do not use on slopes of more than

• 5 when mowing on side hills;

• 10 when mowing uphill;

• 15 when mowing downhill.

• 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 going up or

downhill;

• engage clutch slowly, always keep machine in gear,

especially when travelling downhill;

• machine speeds should be kept low on slopes and

during tight turns;

• stay alert for humps and hollows and other hidden

hazards;

• never mow across the face of the slope, unless the

lawnmower is designed for this purpose.

• 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.

• Use counterweight(s) or wheel weights when

suggested in the instruction handbook.

• 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;

• 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.

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.

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.

• Use only Toro-approved attachments. Warranty may

be voided if used with unapproved attachments.

Warning

• Remove obstacles such as rocks, tree limbs, etc. from

the mowing area. Watch for holes, ruts or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.

• 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.

• Mow up and down slopes greater than 5°, not across.

• Mow downhill only on slopes above 10°, never mow

uphill. If a steep slope must be ascended, back up the hill, and drive forward down the hill, keeping the machine in gear.

• Do not operate machine on hillsides or slopes exceeding 15°.

• 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.

m–3318

Adding Fuel

Use unleaded, regular gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.

Important Do not 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.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the machine at all times to provide the following benefits:

• Keeps gasoline fresh during storage of 90 days or less.

For longer storage, drain the fuel tank.

• 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 fuel stabilizer/conditioner to

the gasoline, as directed by the manufacturer.

Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline.

Filling the Fuel Tank

1. Park the machine on a level surface, disengage the

PTO, set the parking brake, lower the attachment lift, stop the engine, and remove the ignition key.

Note: When filling the tank, make sure that the machine is on a level surface so that adequate air space is allowed.

2. Clean around the fuel tank cap and remove the cap.

3. Add fuel until the fuel level is 1/4 to 1/2 in. (6 mm to

13 mm) below the bottom of the filler neck. This space in the tank allows for expansion of the fuel.

Do not fill the fuel tank completely.

4. Install the fuel tank cap securely.

5. Wipe up any gasoline that may have spilled.

Check the Engine Oil Level

1. Park the machine on a level surface, disengage the

PTO, set the parking brake, lower the attachment lift, stop the engine, and remove the ignition key.

2. Open the hood.

3. Clean around the oil dipstick (Fig. 5) so dirt cannot

fall into the dipstick tube and damage the engine.

Figure 6

1. Metal e n d

5. Slide the oil dipstick fully into the dipstick tube

(Fig. 5).

6. Pull the dipstick out and look at the metal end (Fig. 6).

If the oil level is low (near the L mark), add oil; refer to Engine Oil, page 22.

Important Do not overfill the crankcase with oil

because this may result in engine damage.

Check for Debris

Important Operating the engine with a blocked grass

screen, dirty or plugged cooling fins, and/or cooling shrouds removed, will result in engine damage from overheating.

1. Park the machine on a level surface, disengage the

PTO, set the parking brake, lower the attachment lift, stop the engine, and remove the ignition key.

The Safety Interlock System

Understanding the Safety Interlock System

The safety interlock system is designed to prevent the engine from starting unless the following conditions are met:

• You are sitting on the seat

• The brake pedal is depressed

• The PTO is in the off position

The safety interlock system is designed to stop the engine when you do the following:

• You rise from the seat when the brake pedal is released

• You rise from the seat when the PTO is in the on

position.

Operating the Power Take Off (PTO)

The power take off (PTO) runs the various powered attachments such as mowers, snowthrowers, and tillers.

If the ignition key is in the run or lights position and the PTO is engaged, the PTO indicator light will be on. When this light is on, it is a reminder: the implement is being powered and the starter will not crank while the PTO is engaged. Always turn off the PTO before getting off the seat.

Engaging the PTO

1. Press the brake pedal to stop the machine.

2. Move the throttle lever to the fast position.

Important For best performance, always use full

throttle when the PTO is on.

Disengaging the PTO

m–3264

The safety interlock system is designed to stop the PTO when you shift into reverse with the power take off (PTO) engaged.

Operating in Reverse

The tractor has an interlock feature that prevents mowers, snowthrowers, and other PTO powered attachments from operating while the tractor is traveling in reverse. If you shift into reverse with the PTO engaged, the PTO will stop.

If you need to mow or use other PTO powered attachments while in reverse gear, you can temporarily deactivate this interlock. Do not mow while backing up

unless it is absolutely necessary.

Danger

A child or bystander could be backed over by a riding mower with blades engaged and cause serious personal injury or death.

• Do not mow in reverse unless absolutely

necessary.

• Always look backward and down before

backing up.

• Use the KeyChoice switch only if you are

certain no children or other bystanders will appear in the mowing area.

• Always remove both the ignition and

KeyChoice keys and put them in a safe place out of the reach of children or unauthorized users when leaving the unit unattended.

Push the PTO switch to the off position.

Before deactivating this interlock, ensure that there are no children present on or near the property where you are using the tractor, and that none are likely to appear while you are mowing or operating an attachment. Be extra observant after you have chosen to deactivate the interlock because the sound of the tractor’s engine might prevent you from being aware that a child or bystander has entered the area.

If you are certain that you can safely mow or operate an attachment in reverse, complete the following procedure:

1. Engage the PTO.

2. Insert the KeyChoice key into the KeyChoice switch

(Fig. 15).

Note: Do not insert the KeyChoice key unless it is absolutely necessary to mow or operate an attachment in reverse. Always remove both the ignition and the KeyChoice keys and put them in a safe place out of the reach of children when leaving the unit unattended.

Testing the Safety Interlock System

Test the safety interlock system each time before you use the machine. Do not operate the machine if the safety system is not functioning properly. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately.

Hour Meter

PTO Light

When the PTO light is on, it indicates the implement is being powered. The PTO clutch must be disengaged before the engine will start.

Battery Light

The battery light will be on when the key is in the run or lights positions if the battery voltage is below 12.1 volts or above 15.0 volts. If the light comes on at a higher RPM, it is important to have your battery and electrical system checked and the problem corrected.

The hour meter (Fig. 11) records the amount of time the engine has run. Use it to schedule regular maintenance.

Driving Forward or Backward

1. Stop the tractor.

Important Do not shift gears with the tractor in

motion. Internal transmission damage may result.

Important Do not force the shift lever. Applying

slight pressure to the traction control pedal while shifting will help the gears engage.

2. Shift into high (H) or low (L) forward speed with the

High-Low lever (Fig. 11).

Note: Use low for best mowing performance and smoothest operation with all attachments. Use high for transporting or where conditions permit higher speed.

Danger

Driving with excessive speed on slopes can cause you to rollover or lose control, resulting in serious injury or death to you or bystanders.

5. Turn the ignition key to the stop position to stop the

engine.

6. Set the parking brake before getting off; refer to

Setting the Parking Brake, page 13.

• Do not allow the tractor to roll freely in neutral

on slopes.

• Read, understand, and follow all instructions in

the Operator’s Manual and on the machine before starting.

3. Place the throttle control in the fast position for best

performance. (The throttle control regulates engine revolutions per minute.)

4. Place your foot on the traction control pedal and

slowly press on the top of the pedal to move forward, or on the bottom of the pedal to move backward (Fig.

17).

Note: The farther you move the pedal in either direction, the faster the machine will move in that direction.

Children or bystanders may be injured if they move or attempt to operate the tractor while it is unattended.

Always remove the ignition and KeyChoice keys and set the parking brake when leaving the machine unattended, even if just for a few minutes.

Using the Cruise Control

The cruise control is a switch (Fig. 18) on the right fender that maintains a set traction control position without foot pressure. The cruise control only operates when moving forward.

Centering the Steering Wheel (Power Steering Models)

The power steering may not always return the steering wheel to the centered position when you turn the wheels straight forward. If this happens, center the steering wheel using the following procedure:

1. Note the degree to which the steering wheel is out of

center.

2. Turn the steering wheel all the way in the opposite

direction until the front wheels no longer turn.

3. Continue turning the steering wheel by the degree to

which it is off center.

4. Turn the steering wheel in the other direction until the

front wheels aim straight ahead. The steering wheel should now be centered.

Positioning the Tilt Steering Wheel

The steering wheel has four tilt locations. Position the steering wheel where you have the best control of the machine and are most comfortable.

1. Lift the tilt lever to release the lock (Fig. 23).

2. Move the steering wheel to a comfortable position;

then release the lever to lock it in place.

The Smart Turn Steering Feature

The Smart Turn Steering feature automatically lowers the speed of the tractor in tight turns. The decrease in speed is directly proportional to the sharpness of the turn, up to a maximum speed reduction of 40 percent. This allows you to make turns at higher speeds without having to change the speed control position. After the turn, the original speed is automatically restored.

The Smart Turn Steering feature does not affect engine speed.

This system was set at the factory and should not need adjustment.

Danger

Driving with excessive speed while turning can cause you to rollover, resulting in serious injury or death to you or bystanders.

• Do not rely on the Smart Turn steering feature

to avoid accidents while turning.

• Read, understand, and follow all instructions in

the Operator’s Manual and on the machine before starting.

Pushing the Machine by Hand

Important Do not tow the machine because

transmission damage may occur. Always push the machine by hand.

1. Disengage the PTO and stop the engine.

2. Move the High-Low range lever to the neutral position

(N). This allows the rear wheels to turn freely.

3. Push the machine to the desired location.

4. Place the lever high or low after moving the machine,

and set the parking brake.
