SECTION1: IMPORTANTSAFEOPERATIONPRACTICES

WARNING: This symbol points out important safety instructions which, ifnot followed, could endanger

the personal safety and/or property of yourself and others. Read and follow all instructionsin this manual

before attempting to operate this machine. Failure to comply withthese instructionsmay result in personal
injury. When you see this symbol--HEED ITS WARNING.

WARNING: Engine exhaust, some of its constituents, and certain vehicle components contain or emit

chemicals known to State of California to cause cancer and birth defects or other reproductive harm.

WARNING: This machine was built to be operated according to the rules for safe operation inthis

manual. As with any type of power equipment, carelessness or error on the part of the operator can result in
serious injury. This machine is capable of amputating hands and feet and throwing objects. Failure to
observe the following safety instructions could result in serious injury or death.

GeneralOperation

1. Read this operator's manual carefully in its entirety
before attempting to assemble this machine. Read,

understand, and follow all instructions on the
machine and inthe manual(s) before operation. Be

completely familiar with the controls and the proper
use of this machine before operating it. Keep this
manual in a safe place for future and regular
reference and for ordering replacement parts.

2. This machine is a precision piece of power
equipment, not a plaything. Therefore, exercise

extreme caution at all times. Your unit has been
designed to perform one job: to mow grass. Do not

use it for any other purpose.

3. Never allow children under 14 years old to operate

this machine. Children 14 years old and over

should read and understand the operation
instructions and safety rules in this manual and
should be trained and supervised by a parent. Only
responsible individuals who are familiar with these
safe operation rules should use this machine.

4. Thoroughly inspect the area where equipment is to
be used. Remove all stones, sticks, wire, bones,

toys and other foreign objects which could be
tripped over or picked up and thrown by the blade.

Thrown objects can cause serious personal injury.
Plan your mowing pattern to avoid discharge of
material toward roads, sidewalks, bystanders and

the like. Also, avoid discharging material against a
wall or obstruction which may cause discharged

material to ricochet back toward the operator.

5. To help avoid blade contact or a thrown object
injury, stay in the operator zone behind the handles
and keep bystanders, helpers, children and pets at

least 75 feet from the machine while it is in
operation. Stop machine if anyone enters the area.

6. Always wear safety glasses to protect your eyes
during equipment operation and while performing
an adjustment or repair. Thrown objects which
ricochet can cause serious injury to the eyes.

7. Wear sturdy, rough-soled work shoes and close-
fitting slacks and shirts. Shirts and pants that cover
the arms and legs and steel-toed shoes are
recommended. Never operate this machine in bare
feet, sandals, slippery or light weight (e.g. canvas)

shoes.

8. Do not put hands or feet near rotating parts or
under the cutting deck. Contact with the blade can
amputate hands and feet.

9. A missing or damaged discharge cover can cause
blade contact or thrown object injuries.

10. Many injuries occur as a result of the mower being
pulled over the foot during a fall caused by slipping
or tripping. Do not hold on to the mower if you are
falling; release the handle immediately.

11. Never pull the mower back toward you while you
are walking. Ifyou must back the mower away from

a wall or obstruction first look down and behind to
avoid tripping and then follow these steps:

a. Step back from the mower to fully extend

your arms.

b. Be sure you are well balanced with sure

footing.

c. Pull the mower back slowly, no more than

half way toward you.

d. Repeat these steps as needed.

5. Do not operate the mower while under the influence
of alcohol or drugs.

6. Do not engage the self-propelled mechanism on
units so equipped while starting engine.

7. The blade control handle is a safety device. Never
attempt to bypass its operation. Doing so makes
the safety device inoperative and may result in
personal injury through contact with the rotating
blade. The blade control handle must operate
easily in both directions and automatically return to
the disengaged position when released.

8. Never operate the mower in wet grass. Always be
sure of your footing. A slip and fall can cause
serious personal injury. If you feel you are losing

yourfooting,releasethebladecontrolhandle

SlopeOperation

Slopes are a major factor related to slip and fall
accidents which can result in severe injury. Operation
on slopes requires extra caution. If you feel uneasy on a
slope, do not mow it. Before operating this unit on a
slope or hilly area, use the slope gauge on page 6 to
measure slopes. If the slope is greater than 15
degrees, do not mow it.

Do:

1.

Mow across the face of slopes; never up and down.
Exercise caution when changing direction.

2. Watch for holes, ruts, rocks, hidden objects, or

bumps which can cause you to slip or trip. Tall
grass can hide obstacles.

3. Always be sure of your footing. A slip and fall can

cause serious personal injury. If you feel you are
losing your balance, release the blade control
handle immediately, and the blade will stop rotating

within 3 seconds.

DoNot:

1. Do not mow near drop-offs, ditches or

embankments, you could lose your footing or
balance.

2. Do not mow slopes greater than 15 degrees as
shown on the slope gauge.

3. Do not mow on wet grass. Unstable footing could
cause slipping.

Children

Tragic accidents can occur if the operator isnot alert to
the presence of children. Children are often attracted to
the mower and the mowing activity. They do not

understand the dangers. Never assume that children

will remain where you last saw them.

1. Keep children out of the mowing area and under
the watchful care of a responsible adult other than
the operator.

2. Be alert and turn mower off if a child enters the
area.

3. Before and while moving backwards, look behind
and down for small children.

4. Use extreme care when approaching blind corners,
doorways, shrubs, trees, or other objects that may
obscure your vision of a child who may run into the

mower.

5. Keep children away from hot or running engines.
They can suffer burns from a hot muffler.

6. Never allow children under 14 years old to operate
a power mower. Children 14 years old and over
should read and understand the operation
instructions and safety rules in this manual and
should be trained and supervised by a parent.

Service

Safe HandlingofGasoline:

1. To avoid personal injuryor property damage use
extreme care in handling gasoline. Gasoline is
extremely flammable and the vapors are explosive.
Serious personal injury can occur when gasoline is
spilled on yourself or your clothes which can ignite.

2. Wash your skin and change clothes immediately.

3. Use only an approved gasoline container.

4. 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 filling.

5. If possible, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. Ifthis
is not possible, then refuel such equipment on a
trailer with a portable container, rather than from a
gasoline dispenser nozzle.

6. Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.

7. Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

8. Never fuel machine indoors because flammable
vapors will accumulate in the area.

4

9. Never remove gas cap or add fuel while the engine
is hot or running. Allow engine to cool at least two
minutes before refueling.

10. Never over fill fuel tank. Fill tank to no more than ½
inch below bottom of filler neck to provide space for

fuel expansion.

11. Replace gasoline cap and tighten securely.

12. If gasoline is spilled, wipe it offthe engine and
equipment. Move unit to another area. Wait 5
minutes before starting the engine.

13. Never store the machine or fuel container inside

where there is an open flame, spark or pilot light as

on a water heater, space heater, furnace, clothes
dryer or other gas appliances.

14. To reduce fire hazard, keep mower free of grass,
leaves, or other debris build-up. Clean up oil or fuel
spillage and remove any fuel soaked debris.

15. Allow a mower to cool at least 5 minutes before
storing.

GeneralService:

1. Never run an engine indoors or in a poorly
ventilated area. Engine exhaust contains carbon
monoxide, an odorless and deadly gas.

2. Before cleaning, repairing, or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire and
ground against the engine to prevent unintended
starting.

3. Check the blade and engine mounting bolts at

frequent intervals for proper tightness. Also,

visually inspect blade for damage (e.g., bent,
cracked, worn) Replace blade with the original
equipment manufacture's (O.E.M.) blade only,
listed in this manual. "Use of parts which do not
meet the original equipment specifications may

lead to improper performance and compromise
safety!"

4. Mower blades are sharp and can cut. Wrap the
blade or wear gloves, and use extra caution when
servicing them.

5. Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.

6. Never tamper with safety devices. Check their
proper operation regularly.

7. After striking aforeign object, stop the engine,
disconnect the spark plug wire and ground against
the engine. Thoroughly inspect the mower for any
damage. Repair the damage before starting and
operating the mower.

8. Never attempt to make a wheel or cutting height
adjustment while the engine is running.

9. Grass catcher components, discharge cover, and
trail shield are subject to wear and damage which
could expose moving parts or allow objects to be
thrown. For safety protection, frequently check
components and replace immediately with original
equipment manufacturer's (O.E.M.) parts only,
listed in this manual. "Use of parts which do not
meet the original equipment specifications may
lead to improper performance and compromise
safety!"

10. Do not change the engine governor setting or
overspeed the engine. The governor controls the
maximum safe operating speed of the engine.

11. Maintain or replace safety and instruction labels, as
necessary.

12. Observe proper disposal laws and regulations.

Improper disposal of fluids and materials can harm

the environment.
