Safety

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.

This product is capable of amputating hands and feet and

throwing objects. Always follow all safety instructions to

avoid serious injury or death.

This product is designed for cutting and recycling grass or,

when equipped with a grass bagger, for catching cut grass.

Any use for purposes other than these could prove

dangerous to user and bystanders.

Safe Operating Practices

The following instructions are from ANSI standard

B71.4—2004.

Training

•Read the Operator’s Manual and other training material.

If the operator(s) or mechanic(s) can not read English it

is the owner’s responsibility to explain this material to

them.

•Become familiar with the safe operation of the

equipment, operator controls, and safety signs.

•All operators and mechanics should be trained. The

owner is responsible for training the users.

•Never let children or untrained people operate or

service the equipment. Local regulations may restrict

the age of the operator.

•The owner/user can prevent and is responsible for

accidents or injuries occurring to himself or herself,

other people or property.

Preparation

•Evaluate the terrain to determine what accessories and

attachments are needed to properly and safely perform

the job. Only use accessories and attachments approved

by the manufacturer.

•Wear appropriate clothing including hard hat, safety

glasses and hearing protection. Long hair, loose

clothing or jewelry may get tangled in moving parts.

•Inspect the area where the equipment is to be used and

remove all objects such as rocks, toys and wire which

can be thrown by the machine.

•Use extra care when handling gasoline and other fuels.

They are flammable and vapors are explosive.

•Use only an approved container

•Never remove gas cap or add fuel with engine

running. Allow engine to cool before refueling.

Do not smoke.

•Never refuel or drain the machine indoors.

•Check that operator’s presence controls, safety switches

and shields are attached and functioning properly. Do

not operate unless they are functioning properly.

Operation

•Never run an engine in an enclosed area.

•Only operate in good light, keeping away from holes

and hidden hazards.

•Be sure all drives are in neutral and parking brake is

engaged before starting engine. Start the engine only

from the operator’s position.

•Never raise deck with the blades running.

•Never operate without the PTO shield, or other guards

securely in place. Be sure all interlocks are functioning

properly.

•Never operate with the discharge deflector raised,

removed or altered, unless using a grass catcher.

•Do not change the engine governor setting or overspeed

the engine.

•Stop on level ground, lower implements, disengage

drives, engage parking brake, shut off engine before

leaving the operator’s position for any reason including

emptying the catchers or unclogging the chute.

•Stop equipment and inspect blades after striking objects

or if an abnormal vibration occurs. Make necessary

repairs before resuming operations.

•Keep hands and feet away from the cutting units.

•Never carry passengers and keep pets and bystanders

away.

•Be alert, slow down and use caution when making

turns. Look behind and to the side before changing

directions.

•Slow down and use caution when crossing roads and

sidewalks. Stop blades if not mowing.

•Be aware of the mower discharge direction and do not

point it at anyone.

•Do not operate the mower under the influence of

alcohol or drugs.

•Use extreme care when loading or unloading the

machine into a trailer or truck.

•Use care when approaching blind corners, shrubs, trees,

or other objects that may obscure vision.

Slope Operation

•Do not mow slopes greater than 15 degrees.

•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.

•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.

Using the Rollover Protection System

(ROPS)

•Keep the roll bar in the raised and locked position and

use the seat belt when operating the machine.

•Be certain that the seat belt can be released quickly in

the event of an emergency.

•Be aware there is no rollover protection when the roll

bar is down.

•Check the area to be mowed and never fold the ROPS

in areas where there are slopes, drop offs or water.

•Lower the roll bar only when absolutely necessary. Do

not wear the seat belt with the roll bar folded down.

•Check carefully for overhead clearances (i.e. branches,

doorways, electrical wires) before driving under any

objects and do not contact them.

Maintenance and storage

•Disengage drives, lower implement, set parking brake,

stop engine and remove key or disconnect spark plug

wire. Wait for all movement to stop before adjusting,

cleaning or repairing.

•Clean grass and debris from cutting units, drives,

mufflers, and engine to help prevent fires. Clean up oil

or fuel spillage.

•Let engine cool before storing and do not store near

flame.

•Shut off fuel while storing or transporting. Do not store

fuel near flames or drain indoors.

•Park machine on level ground. Never allow untrained

personnel to service machine.

•Use jack stands to support components when required.

•Carefully release pressure from components with stored

energy.

•Disconnect battery or remove spark plug wire before

making any repairs. Disconnect the negative terminal

first and the positive last. Reconnect positive first and

negative last.

•Use care when checking blades. Wrap the blade(s) or

wear gloves, and use caution when servicing them.

Only replace blades. Never straighten or weld them.

•Keep hands and feet away from moving parts. If

possible, do not make adjustments with the engine

running.

•Charge batteries in an open well ventilated area, away

from spark and flames. Unplug charger before

connecting or disconnecting from battery. Wear

protective clothing and use insulated tools.

•Keep all parts in good working condition and all

hardware tightened. Replace all worn or damaged

decals.

•Use only Toro-approved attachments. Warranty may be

voided if used with unapproved attachments.

Slope Chart

Fold along appropriate line

Align this edge with a vertical surface

(Tree, Building, Fence post, pole, etc.)

Example: Compare

slope with folded

edge.

Safety and Instruction Decals

Safety decals and instructions are easily visible to the operator and are located near any area

of potential danger. Replace any decal that is damaged or lost.
