· 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.
2
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,

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.

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

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.
4
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.
