SAFETY INSTRUCTIONS

The following safety instructions are based

on B71.1, B71.4 specifications of the

American National Standards Institute and

ISO 5395 in effect at the time of production.

Safe Practices for Ride-On Mowers

If used improperly, this machine is capable of

amputating hands and feet and throwing

objects. Failure to observe the following

safety instructions could result in serious

injury or death. Use only for purposes

intended as set forth in the Operator's

Manual. Other use is improper and may

cause serious injury or death.

General Information

Read, understand, and follow instructions

and warnings in this manual and on the

machine, engine and attachments.

Only allow operators, who are responsible,

trained, familiar with the instructions, and

physically capable to operate the machine.

DO NOT carry passengers and keep people

or pets away from the mowing area.

DO NOT operate the machine while

physically or mentally impaired, feeling tired,

ill or under the influence of alcohol or drugs.

Follow the manufacturer’s recommendation

for wheel weights or counterweights.

DO NOT touch parts which are hot. Allow

parts to cool.

Preparation Before Operating

Inspect unit before each use for missing or

damaged decals and shields, correctly

operating safety interlock system, ROPS

and deterioration of grass catchers. Replace

or repair as needed.

Clear the operating area of all objects which

could be thrown by or interfere with

operation of the machine.

Keep the area of operation clear of all

bystanders, particularly small children. Stop

the machine and attachment(s) if anyone

enters the area

DO NOT operate the machine without the

entire grass catcher, discharge chute, or

other safety devices in place and functioning

properly. Check frequently for signs of

damage, wear or deterioration and replace

as needed.

NEVER tamper with safety devices. Check

their proper operation regularly. NEVER do

anything to interfere with the intended

function of a safety device or to reduce the

protection provided by the safety device.

Check parking brake operation frequently.

Adjust and service as required.

Wear appropriate personal protective

equipment such as safety glasses, hearing

protection, and substantial footwear. DO

NOT mow barefoot or while wearing

sandals.

Operating

Improper use of power equipment can cause

serious permanent injury or death to the

operator or a bystander. Understand:

• How to operate all controls

• The functions of all controls

• How to STOP in an emergency

• Braking and steering characteristics

• Turning radius and clearances

If the operator or the mechanic cannot read

the manual, it is the owner’s responsibility to

explain it to them.Manuals are available in

other languages at www.gravely.com.

Only run the engine in well ventilated areas.

Exhaust gases contain carbon monoxide, an

odorless deadly poison.

Only operate the machine in daylight or

good artificial light.

Avoid holes, ruts, bumps, rocks and other

hazards. Uneven terrain could overturn the

machine, or cause operator to lose their

balance, footing and/or control of the mower.

DO NOT put hands or feet near rotating

parts or under the machine. Keep clear of

the discharge opening at all times.

Avoid slippery surfaces. ALWAYS be sure of

your footing.

Stop engine before removing grass catcher

or unclogging chute.

DO NOT direct discharge material toward

anyone. Avoid discharging material against

a wall or obstruction. Material may ricochet

back toward the operator. Stop the blade(s)

when crossing gravel surfaces. DO NOT

mow into roads or across sidewalks.

EN - 8

DO NOT leave a running machine

unattended. ALWAYS park on level ground,

disengage the attachment, set parking

brake, stop engine and remove key (if

applicable) before leaving the operator's

position.

DO NOT mow in reverse unless absolutely

necessary. ALWAYS look down and behind

before and while backing.

Lightning can cause severe injury or death.

If lightning is seen or thunder is heard in the

area, DO NOT operate the machine; seek

shelter.

If you strike a foreign object, stop and

inspect the machine. Repair, if necessary,

before restarting.

ALWAYS check overhead and side

clearances carefully before operation. Keep

in mind that your mower deck may be wider

than your track width.

Children Specific

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 operating area and

under the watchful care of a responsible

adult other than the operator.

Do not carry children, even with the blade(s)

shut off. Children could fall off and be

seriously injured or interfere with safe

machine operation. Children who have been

given rides in the past could suddenly

appear in the mowing area for another ride

and be run over or backed over.

DO NOT allow children under the age of 18

to operate any outdoor power equipment.

Slope Specific

Slopes are a major factor related to

accidents. Operation on slopes requires

extra caution. If you feel uneasy on a slope

DO NOT mow it. Use the parking brake for

emergency stops.

DO Not operate on slopes of more than 15°.

Do not mow within 1.2 M (4 feet) of a drop

off. Do not mow within 1.2 M (4 feet) of a

pond or other waterway.

The primary hazard of slope operation is

loss of control and/or roll over.

Mow up and down slopes, NEVER across.

Exercise caution when changing direction

on slopes. Use caution while operating near

dropoffs.

Avoid mowing wet grass. Wet surfaces can

cause a loss of traction and control.

DO NOT operate machine under any

condition where traction, steering, or stability

is in question. Tires could slide even if the

wheels are stopped.

Always keep the machine in gear when

going down slopes. Do not coast downhill.

Avoid starting and stopping on slopes. Avoid

making sudden changes in speed or

direction. Make turns slowly and gradually.

Use extra care while operating machine with

a grass catcher or other attachment(s). They

can affect the stability of the machine.

Fire and Fuel Specific

Extinguish all cigarettes, cigars, pipes and

other sources of ignition.

Use only an approved fuel container.

DO NOT remove fuel cap or add fuel with

the engine running or while hot.

DO NOT refuel indoors or in enclosed

spaces.

DO NOT store the machine or fuel container,

or refuel, where there is an open flame,

spark, or pilot light such as on a water

heater or other appliance.

If fuel is spilled, DO NOT attempt to start the

engine and avoid creating any source of

ignition until fuel vapors have dissipated.

To help prevent fires: keep machine free of

grass, leaves, or other debris build up; clean

up oil or fuel spillage and remove any fuel

soaked debris; allow engine to cool before

storing.

Use extra care in handling gasoline and

other fuels. They are flammable and vapors

are explosive.

Hauling

Use a single full-width ramp for loading and

unloading a machine for transport. Secure

with appropriate straps.

Towing

Follow the manufacturer’s recommendation

for weight limits for towed equipment and

towing on slopes.
