Using a Spark Arrestor
The engine in this machine is not equipped with a spark arrestor muffler.
The California Public Resources Code, section 4442.5 provides as
follows:
No person shall sell, offer for sale, lease, or rent to any person any internal
combustion engine subject to Section 4442 or 4443, and not subject to
Section 13005 of the Health and Safety Code, unless the person provides
a written notice to the purchaser or bailee, at the time of sale or at the time
of entering into the lease or rental contract, stating that it is a violation of
Section 4442 or 4443 to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land unless the engine is equipped with
a spark arrestor, as defined in Section 4442, maintained in effective
working order or the engine is constructed, equipped, and maintained for
the prevention of fire pursuant to Section 4443. Cal. Pub. Res. Code
4442.5.
Other states or jurisdictions may have similar laws. A spark arrestor for
your machine may be available from your authorized dealer. An installed
spark arrestor must be maintained in good working order by the operator.
Checking Mowing Area
• Clear mowing area of objects that might be
thrown. Keep people and pets out of mowing
area.
• Low-hanging branches and similar obstacles
can injure the operator or interfere with
mowing operation. Before mowing, identify potential obstacles such as
low-hanging branches, and trim or remove those obstacles.
• Study mowing area. Set up a safe mowing pattern. Do not mow where
traction or stability is doubtful.
Rotating Blades are Dangerous -
Protect Children 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 lawnmowing machines and mowing activity. Stay aler t 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.
Operating Safely on Slopes
• Slopes are a major factor related to slip and fall accidents which can
result in severe injury. Operation on all slopes requires extra caution. If you
feel uneasy on a slope, do not mow it.
• Mow across the face of slopes, never up and down. Use extreme caution
when changing direction on slopes.
• Watch for holes, ruts, bumps, rocks or other hidden objects. Uneven
terrain could cause a slip and fall accident. Tall grass can hide obstacles.
• Do not mow on wet grass or excessively steep slopes. Poor footing could
cause a slip and fall accident.
• Do not mow near drop offs, ditches, or embankments. The operator
could lose footing or balance.
• Use extra care with grasscatchers. These can change the stability of the
machine. Do not use grasscatcher on steep slopes.
Wear Appropriate Clothing
• Always wear eye protection when operating
the machine.
• Wear close fitting clothing and safety

SAFETY
equipment appropriate for the job.
• While operating this machine, 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.
Practice Safe Maintenance
• Only qualified, trained adults should service
this machine. Understand service procedure
before doing work.
• Never operate machine in a closed area
where dangerous carbon monoxide fumes can collect.
• Keep all nuts and bolts tight, especially blade attachment bolts, to be
sure the equipment is in safe working condition.
• Never tamper with safety devices. Check their proper operation regularly.
• Keep machine free of grass, leaves or other debris build-up. Clean up oil
or fuel spillage and remove any fuel-soaked debris. Allow the machine to
cool before stor ing.
• If you strike a foreign object, stop and inspect the machine. Repair, if
necessary, before restarting.
• Never make adjustments or repairs with the engine running. Wait for all
movement to stop before adjusting, cleaning or repairing. Disconnect the
spark plug wire, and ground against the engine to prevent accidental
starting.
• 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.
• Mower blades are sharp. Wrap the blade or wear gloves, and use extra
care when servicing them. Only replace blades. Never straighten or weld
them.
• Do not change the governor setting or overspeed the engine.
• Maintain or replace safety and instruction labels, as necessary.
• Keep hands, feet, clothing, jewelry, and long hair away from any moving
parts, to prevent them from getting caught.
• Never attempt to make wheel height adjustments while the engine is
running.
• Keep all parts in good condition and properly installed. Fix damage
immediately. Replace worn or broken parts.
• Do not strike the flywheel with a hammer or hard object because the
flywheel may later shatter during operation.
Prevent Fires
• Machine fires and structure fires can occur if a machine is stored before
allowing it to cool, if debris is not removed from critical areas of the
machine, or if machine is stored near combustible materials.
• Remove grass and debris completely from engine compartment and
muffler area, and from on top of the mower deck, before and after
operating machine, especially after mowing or mulching in dry conditions.
• Empty any grasscatcher bags or containers 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 necessar y.
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 lockopen 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 author ized 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.
