Protect Children
MX18014
• Death or serious injury can occur when young children
associate having fun with a lawn mowing machine simply
because someone has given them a ride on a machine.
• Children are attracted to lawn mowing machines and mowing
activities. They don't understand the dangers of rotating blades
or the fact that the operator is unaware of their presence.
• Children who have been given rides in the past may suddenly
appear in the mowing area for another ride and be run over or
backed over by the machine.
• Tragic accidents with children can occur if the operator is not
alert to the presence of children, especially when a child
approaches a machine from behind. Before and while backing
up, stop mower blades and look down and behind the machine
carefully, especially for children.
• Never carry children on a machine or attachment, even with
the blades off. Do not tow children in a cart or trailer. They can
fall off and be seriously injured or interfere with safe machine
operation.
• Never use the machine as a recreational vehicle or to entertain
children.
• Never allow children or an untrained person operate the
machine. Instruct all operators not to give children a ride on the
machine or in an attachment.
• Keep children indoors, out of the mowing area, and in the
watchful eye of a responsible adult, other than the operator,
when a mower is being operated.
• Stay alert to the presence of children. Never assume that
children wilt remain where you last saw them. Turn the
machine off if a child enters the work area.
Avoid Tipping
• Slopes are a major factor related to loss-of-control and tip-over
accidents, which can result in severe injury or death. Operation
on all slopes requires extra caution.
• Mow across slopes, not up and down.
• Watch for holes, ruts, bumps, rocks, or other hidden objects.
Uneven terrain could overturn the machine. Tall grass can hide
obstacles.
• Choose a low ground speed so you will not have to stop or
shift while on a slope.
• Do not mow or operate machine on wet grass. Tires may lose
traction. Tires may lose traction on slopes even though the
brakes are functioning properly.
• Avoid starting, stopping or turning on a slope. If the tires lose
traction, disengage the blades and proceed slowly, straight
down the slope.
GB-6
• Keep all movement on slopes slow and gradual. Do not make
sudden changes in speed or direction, which could cause the
machine to roll over.
• Use extra care while operating machine with grass catchers or
other attachments, they can affect stability of the machine. Do
not use on steep slopes.
• Do not mow near drop-offs, ditches, embankments, or bodies
of water. The machine could suddenly roll over if a wheel goes
over the edge or the edge caves in.
• Follow the manufacturer's recommendations for wheel weights
or counterweights for added stability when operating on slopes
or using front or rear mounted attachments. Remove weights
when not required.
• Drive machine very slowly and avoid quick stops when
attachment is removed.
• Transport machine with decks lowered to improve stability.
Keep Riders Off
• Only allow the operator on the machine. Keep riders off.
• Riders on the machine or attachment may be struck by foreign
objects or thrown off the machine causing serious injury.
• Riders obstruct the operator's view resulting in the machine
being operated in an unsafe manner.
Avoid High Pressure Fluids
• Hydraulic hoses and lines can fail due to physical damage,
kinks, age, and exposure. Check hoses and lines regularly.
Replace damaged hoses and lines.
• Hydraulic fluid connections can loosen due to physical
damage and vibration. Check connections regularly. Tighten
loose connections.
• Escaping fluid under pressure can penetrate the skin causing
serious injury. Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines. Tighten all connections
before applying pressure.
• Search for leaks with a piece of cardboard. Protect hands and
body from high pressure fluids.
• If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a few
hours or gangrene may result. Doctors unfamiliar with this type
of injury should reference a knowledgeable medical source.
Checking Wheel Hardware
• A serious accident could occur causing serious injury if wheel
hardware is not tight.
• Check wheel hardware tightness often during the first 100
hours of operation.
• Wheel hardware must be tightened to specified torque using
the proper procedure anytime it is loosened.
Wear Appropriate Clothing
• Always wear safety goggles, or safety glasses with side
shields, and a hard hat when operating the machine.
• Wear close fitting clothing and safety equipment appropriate
for the job.
• While mowing, always wear substantial footwear and long
trousers. Do not operate the equipment when barefoot or
wearing open sandals.
• Wear a suitable protective device such as earplugs. Loud
noise can cause impairment or loss of hearing.
Maintenance and Storage
• Never operate machine in a closed area where dangerous
carbon monoxide fumes can collect.
• Disengage drives, lower implement, lock parking brake, stop
engine and remove key or disconnect spark plug (for gas
engines). 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. Understand service procedure
before doing work.
• Use jack stands or lock service latches to support components
when required. Securely support any machine elements that
must be raised for service work.
• Before servicing machine or attachment, carefully release
pressure from any components with stored energy, such as
hydraulic components or springs.
• Release hydraulic pressure by lowering attachment or cutting
units to the ground or to a mechanical stop and move hydraulic
control levers back and forth.
• Disconnect battery or remove spark plug (for gas engines)
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 blades or wear
gloves, and use caution when servicing them. Only replace
blades. Never straighten or weld them.
• Keep hands, feet, clothing, jewelry and long hair 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.
• Check grass catcher components and the discharge guard
frequently and replace with manufacturer's recommended
parts, when necessary. Grass catcher components are subject
to wear, damage, and deterioration which could expose
moving parts or allow objects to be thrown.
• Keep all nuts and bolts tight, especially blade attachment bolts,
to be sure the equipment is in safe working condition.
• Check brake operation frequently. Adjust and service as
required.
• On multi-bladed machines, take care as rotating one blade can
cause other blades to rotate.
GB - 7
Prevent Fires
• Remove grass and debris from engine compartment and
muffler area, before and after operating machine, especially
after mowing or mulching in dry conditions.
• Empty the grass catcher completely before storing.
• Always shut off fuel when storing or transporting machine, if
the machine has a fuel shutoff.
• Do not store machine near an open flame or source of ignition,
such as a water heater or furnace.
• Check fuel lines, tank, cap, and fittings frequently for cracks or
leaks. Replace if necessary.
Tire Safety
Explosive separation of a tire and rim parts can cause serious injury
or death:
• Do not attempt to mount a tire without the proper equipment
and experience to perform the job.
• Always maintain the correct tire pressure. Do not inflate the
tires above the recommended pressure. Never weld or heat a
wheel and tire assembly. The heat can cause an increase in air
pressure resulting in a tire explosion. Welding can structurally
weaken or deform the wheel.
• When inflating tires, use a clip-on chuck and extension hose
long enough to allow you to stand to one side and NOT in front
of or over the tire assembly.
• Check tires for tow pressure, cuts, bubbles, damaged rims or
missing lug bolts and nuts.
Handling Fuel Safely
To avoid personal injury or property damage, use extreme care in
handling fuel. Fuel is extremely flammable and fuel vapors are
explosive:
• Extinguish all cigarettes, cigars, pipes, and other sources of
ignition.
• Use only an approved fuel container. Use only non-metal,
portable fuel containers approved by the Underwriter's
Laboratory (U.L.) or the American Society for Testing &
Materials (ASTM). If using a funnel, make sure it is plastic and
has no screen or filter.
• Never remove the fuel tank cap or add fuel with the engine
running. Allow engine to cool before refueling.
• Never add fuel to or drain fuel from the machine indoors. Move
machine outdoors and provide adequate ventilation.
• Clean up spilled fuel immediately. If fuel is spilled on clothing,
change clothing immediately. If fuel is spilled near machine, do
not attempt to start the engine but move the machine away
from the area of spillage. Avoid creating any source of ignition
until fuel vapors have dissipated.
• Never store the machine or fuel container where there is an
open flame, spark, or pilot light such as on a water heater or
other appliance.
• Prevent fire and explosion caused by static electric discharge.
Static electric discharge can ignite fuel vapors in an
ungrounded fuel container.
• Never fill containers inside a vehicle or on a truck or trailer bed
with a plastic liner. Always place containers on the ground
away from your vehicle before fueling.
• Remove fuel-powered equipment from the truck or trailer and
refuel it on the ground. If this is not possible, then refuel such
equipment with a portable container, rather than from a fuel
dispenser nozzle.
• Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until the fueling is complete. Do
not use a nozzle lock-open device.
• Never overfill fuel tank. Replace fuel tank cap and tighten
securely.
• Replace all fuel container caps securely after use.
• For gasoline engines, do not use gas with methanol. Methanol
is harmful to your health and to the environment.
Handling Waste Product and Chemicals
• Waste products, such as, used oil, fuel, coolant, brake fluid,
and batteries, can harm the environment and people:
• Do not use beverage containers for waste fluids - someone
may drink from them.
• See your local Recycling Center or authorized dealer to learn
how to recycle or get rid of waste products.
• A Material Safety Data Sheet (MSDS) provides specific details
on chemical products: physical and health hazards, safety
procedures, and emergency response techniques. The seller
of the chemical products used with your machine is
responsible for providing the MSDS for that product.
