and Prevent
Accidents
Protect Children:
• Tragic accidents can occur if the
operator is not alert to the presence of
children. Children are often attracted
to lawn-mowing machines and
mowing activity. Stay alert to the
presence of children. Never assume
that children will remain where you last
saw them.
• 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.
• Be alert and turn mower off if a child
enters the work area. They don’t
understand the dangers of rotating
blades or the fact that the operator is
unaware of their presence.
• Never allow a child or an untrained
person to operate the machine.
• Use extra care when approaching
blind corners, shrubs, trees, or other
objects that may block your view of a
child.
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,
when operating the machine.
• Wear close fitting clothing and safety
equipment appropriate for the job.

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.
•Disengage drives,
GB - 9
• 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 grasscatcher components and
the discharge guard frequently and
replace with manufacturer’s
recommended parts, when necessary.
Grasscatcher components are subject
to wear, damage, and deterioration
which could expose moving parts or
allow objects to be thrown.
• Keep all nuts and bolts t ight, 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.
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.
Prevent Fires
• Machine fires and structure fires can
occur if a machine is stored before
allowing it to cool, or if debris is not
removed from around the engine and
muffler, or if stored near combustible
materials.
• Remove grass and debris from engine
compartment and muffler area, before
and after operating machine,
especially after mowing or mulching in
dry conditions.
GB - 10
• Empty the grasscatcher 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
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 low pressure, cuts,
bubbles, damaged rims or missing lug
bolts and nuts.

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.
• Fuel is highly flammable and its
vapors are explosive. Handle with
care. Use only an approved gasoline
container with an appropriately sized
