SECTION1: IMPORTANTSAFEOPERATIONPRACTICES
WARNING: This symbol points out important safety instructions which, if not followed, could
endanger the personal safety and/or property of yourself and others. Read and follow all instructions in
this manual before attempting to operate this machine. Failure to comply with these instructions may
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.
DANGER: This machine was built to be operated according to the rules for safe operation in this
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 in the 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 rules of safe operation should be allowed to use
this machine.
4. Thoroughly inspect the area where the 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
children, bystanders, helpers and pets at least 75 feet
from the mower while it is in operation. Stop machine if
anyone enters the area.
6. Always wear safety glasses or safety goggles during
operation and while performing an adjustment or repair to
protect your eyes. 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. If you 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.
12. Do not operate the mower while under the influence of
alcohol or drugs.
13. Do not engage the self-propelled mechanism on units so
equipped while starting engine.
14. The blade control handle is asafetydevice. 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.
15. 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 your footing, release the
blade control handle immediately and the blade will stop
rotating within three seconds.
16. Mow only in daylight or in good artificial light. Walk, never
run.
17. Stop the blade when crossing gravel drives, walks or
roads.
18. If the equipment should start to vibrate abnormally, stop
the engine and check immediately for the cause.
Vibration is generally awarning of trouble.

injury.
23. If sitcations occur which are not covered in this manual,
use care and good judgment. Contact your dealer for
assistance. Telephone [phone] for the name of
your nearest dealer.
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. For your safety, use the slope gauge included as part
of this manual to measure slopes before operating this unit on
a sloped or hilly area. 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 extreme caution when changing direction on
slopes.
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 is not 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.
Keep children away from hot or running engines. They
can suffer burns from a hot muffler.
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.
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 avehicle or on a truck or
trailer bed with a plastic liner. Always place containers on
the ground away from your vehicle before filling.
5. When practical, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. If this 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.
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. ffgasoline is spilled, wipe itoff the 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 freeof 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.
General Service:
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. Checkthebladeandenginemountingboltsatfrequent

WARNING: Keep hands and feet away
from chute area on the cutting deck. The
operation of any lawn mower can result in
foreign objects being thrown into the
eyes, which can result in severe eye
damage. Always wear safety glasses or
eye shields.
NOTE: For shipping purposes your mower is set with
the wheels in a low cutting height position. For best
results raise the cutting position until it is determine
which height is best for your lawn. See the adjustment
section for details.
GasandOilFill-Up
Service the engine with gasoline and oit as instructedin
the separate engine manual packed with your mower.
Read instructions carefully.
WARNING: Never fill fuel tank indoors with
engine running or until the engine has
been allowed to cool for at least two
minutes after running.
BeforeStartingYourMower
Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark ptugwire is
fastened securely over the metal tip on the spark
plug.
Check for proper drive clutch operation using the
NEUTRAL ADJUSTMENT TEST.
NeutralAdjustmentTest
To perform the neutral adjustment test answer the
following questions.
With the drive clutch control released, push mower
forward and pult it backward. Does it move freely?
Squeeze the drive clutch control and pull the
mower backward. Do the rear wheels lock?
Is the drive clutch control cable free of kinks or
sharp bends?
If you answered "yes" to all three questions, your
mower passed the test and you can start your
mower.
If you answered "no" to any of the three questions,
you will have to adjust the drive clutch control as
instructed in the ADJUSTMENT SECTION.
StartingEngine
Prime engine as instructed in the separate engine
manual packed with your unit.
Your lawn mower is equipped with a constant
speed throttle, which is set at fult throttle for best
performance.
Stand behind the mower and squeeze the blade
control handle against the upper handle.
Grasp recoil starter handle and pull rope out slowly
until engine reaches the start of compression cycle
(rope will pult slightly harder at this point). Let the
rope rewind slowly. Pull rope with a rapid,
continuous, fult arm stroke. Keeping a firm grip on
the starter handle, let the rope return to the starter
slowly.
StoppingEngine
Release blade control handle to stop the engine
and the blade.
Disconnect spark plug wire and ground it to the
post on the engine.
UsingYourLawnMower
Be sure that the lawn is clear of stones, sticks, wire, or
other objects which could damage the lawn mower or

the engine. Such objects could be accidently thrown by
the mower in any direction and cause serious personal
injury to the operator and others.
For best results, do not cut wet grass because it tends
to stick to the underside of the mower, preventing
proper discharge of grass clippings, and could cause
you to slip and fall. New grass, thick grass, orwet grass
may require anarrower cut.
For ahealthier lawn, never cut off more than one-third
of the total length of the grass. Your lawn should be cut
in the fall as long as there is growth. This mower is
designed to be operated at full throttle to give you the
best cut and do the most effective job of mowing or
mulching.
WARNING: If you strike a foreign object,
stop the engine. Remove wire from the
spark plug, thoroughly inspect the mower
for any damage, and repair the damage
before restarting and operating the
mower. Extensive vibration of the mower
during operation is an indication of
damage. The unit should be promptly
inspected and repaired.
Mulching
For effective mulching, do not cut wet grass because it
tends to stick to the underside of the deck, preventing
proper mulching of grass clippings. New or thick grass
may require a narrower cut. The ground speed should
be adjusted to the condition of the lawn. If mowing has
been delayed and the grass has been allowed to grow
in excess of 4", mulching is not recommended. Mow
using the grass bag to reduce the grass height to 3 1/4"
maximum before mulching.
AttachingTheGrassBag
Remove three wing nuts holding the mulching
baffle or side discharge chute in place and remove
from unit. See Figure 7.
