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
· 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 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.

7
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 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, concern, prudence, 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.

· 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; keep 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.
1.4.4 Use extreme 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.
· Reduce speed and use extreme caution on slopes.
· Avoid sudden turns or rapid speed changes.

9
Use a hand trimmer only near drop-offs, ditches, steep banks, or water. This area can be dangerous, see Figure 1.
Progressively 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.
1.4.5 Stop the blades when transporting the mower to and from the area to be mowed.
1.4.6 Never operate the mower with defective guards, shields, or covers. Always have safety shields, guards, switches,
and other devices in place and in proper working condition.
1.4.7 DO NOT change the engine governor setting or overspend the engine. Operating an engine at excessive speed may
increase the hazard of personal injury.
1.4.8 Disengage PTO before starting engine.
1.4.9 Start the engine carefully with feet well away from the blades.
1.4.10 Keep hands, feet, and clothing away from rotating parts while the mower is being operated.
