POTENTIAL HAZARD

· Engine exhaust contains carbon monoxide, which

is an odorless deadly poison.

WHAT CAN HAPPEN

· Carbon monoxide can kill you.

HOW TO AVOID THE HAZARD

· Do not run engine indoors or in a small confined

area where dangerous carbon monoxide fumes can

collect.

POTENTIAL HAZARD

· This machine produces sound levels in excess of

85 dBA at the operator’s ear when in operation.

WHAT CAN HAPPEN

· Exposure to sound levels of 85dBA or above for

extended periods of time can cause hearing loss.

HOW TO AVOID THE HAZARD

· Wear hearing protection when operating this

machine.

POTENTIAL HAZARD

· In certain conditions gasoline is extremely

flammable and highly explosive.

WHAT CAN HAPPEN

· A fire or explosion from gasoline can burn you,

others, and cause property damage.

HOW TO AVOID THE HAZARD

· Do not smoke while refueling and stay away from

an open flame or where gasoline fumes may be

ignited by a spark.

· Refuel only outdoors.

· Store gasoline in an approved container and keep

it out of the reach of children.

· Add fuel before starting the engine. Never remove

the cap of the fuel tank or add fuel when engine is

running or when the engine is hot.

· Never fill the fuel tank so that gasoline level rises

above a level that is 3/8"(10mm) below the

bottom of the filler neck to allow for gasoline

expansion and to prevent fuel spillage.

· If fuel is spilled, DO NOT attempt to start the

engine. Move away from the area of the spill and

avoid creating any source of ignition of the fuel

until vapors have dissipated.

· Do not operate without entire exhaust system in

place and in proper working condition.

POTENTIAL HAZARD

· In certain conditions gasoline is extremely

flammable and highly explosive.

WHAT CAN HAPPEN

· A static charge can ignite gasoline vapors. A fire

or explosion from gasoline can burn you, others,

and cause property damage.

HOW TO AVOID THE HAZARD

· Purchase and store gasoline only in an approved

container.

· Always place gasoline containers on the ground

away from your vehicle while 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.

POTENTIAL HAZARD

· Gasoline vapor can collect inside enclosed trailers

and may be ignited by electrical sparks or hot

engine/exhaust components.

WHAT CAN HAPPEN

· Explosion and fire may occur, resulting in

property damage, personal injury, and/or death.

HOW TO AVOID THE HAZARD

· Provide adequate ventilation of any enclosed

trailer to prevent build up of gasoline vapors,

especially at floor level.

· Refuel only outdoors, never inside an enclosed

trailer.

· Be sure all fuel tanks and gasoline storage

containers have proper caps installed to prevent

spillage and minimize vapor escaping into the

trailer.

· Do not place any equipment that is leaking

gasoline into an enclosed trailer.

1.4 OPERATION

Although hazard control and accident prevention

partially are dependent upon the design and

configuration of the equipment, these factors are also

dependent upon the awareness and proper training of

the personnel involved in the operation, transport,

maintenance, and the storage of the equipment. It is

essential that all Operator Safety Mechanisms be

connected and in operating condition prior to use for

mowing.

POTENTAL HAZARD

· Operating engine parts, especially the muffler,

become extremely hot.

WHAT CAN HAPPEN

· Severe burns can occur on contact.

· Debris, such as leaves, grass, brush, etc. can catch

fire.

HOW TO AVOID THE HAZARD

· Allow engine parts, especially the muffler, to cool

before touching.

· Remove accumulated debris from muffler and engine

area.

· Install and maintain in working order a spark arrester

before using equipment on forest-covered,

grass-covered, or brush-covered unimproved land.

POTENTIAL HAZARD

· Hands, feet, hair, clothing, or accessories can become

entangled in rotating parts.

WHAT CAN HAPPEN

· Contact with rotating parts can cause traumatic

amputation or severe lacerations.

HOW TO AVOID THE HAZARD

· Do not operate the machine without guards, shields,

and safety devices in place and working properly.

· Keep hands, feet, hair, jewelry, or clothing away

from rotating parts.

1.4.1 Give complete, undivided attention to the

job at hand.

1.4.2 Mow only in daylight or good artificial

light, keeping away from holes and hidden hazards.

NEVER carry passengers. Do not operate the mower

when children or others are in the area!

1.4.3 When feasible, avoid operating the

equipment in wet grass especially on slopes.

1.4.4 Use caution when mowing and/or turning

on slopes as loss of traction and/or tip-over could

occur. The operator is responsible for safe operation

on slopes.

POTENTIAL HAZARD

· Mowing on wet grass or steep slopes can cause

sliding and loss of control.

WHAT CAN HAPPEN

· Wheels dropping over edges, ditches, steep banks,

or water can cause rollovers, which may result in

serious injury, death, or drowning.

HOW TO AVOID THE HAZARD

· Do not mow on slopes when grass is wet.

· Do not mow near drop-offs or near water.

· Do not mow on slopes greater than 15 degrees.

·Do not mow on slopes greater than 10 degrees when

grass catcher is installed.

· Reduce speed and use extreme caution on slopes.

· Avoid sudden turns or rapid speed changes.

 Use a walk behind mower /or a hand trimmer

near drop-offs, ditches, steep banks, or water.

This area can be dangerous, see Figure1.

 Greater care is needed as the slope increases.  Always avoid sudden starting or stopping on a

slope. If tires lose traction, disengage the blades

and proceed slowly off the slope.

 Avoid sudden starts when mowing uphill. 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.

 Watch for ditches, holes, rocks, dips, and rises

that change the operating angle, as rough terrain

could overturn the machine.

 Use extreme care with grass catchers or

attachments. These can change the stability of the

machine and cause loss of control.
