information.

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 awalt or obstruction which may cause
discharged material to ricochet back toward the operator.

5. To help avoid blade contact or athrown 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 welt balanced with sure footing.
c. Pull the mower back slowly, no more than halfway

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 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.

15. Never operate the mower inwet 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 a warning of trouble.

19. Shut the engine off and wait until the blade comes to a

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. Ifyou 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.

8,

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 injury or 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. When practical, 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

wilt 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. If gasoline is spilled, wipe it off 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 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. Checkthebladeandenginemountingboltsatfrequent

f

TowardsBetterMowerPerformance

1. Pour fresh, clean gasoline into the mower's gas 5.
tank until the tank is full. Do not use gasoline

that is more than 30 days old. 6.

2. Make sure to connect the mower's spark plug
wire before trying to start the engine.

3. Add engine oil to the oil fill on the mower engine. 7.
Check the dipstick and add more if necessary.

Remember that the oil level has to touch the fill
line. 8.

4. Locate the primer decal near the primer bulb on
the engine, and read its instruction. Using your 9.
thumb, press the primer bulb slowly as many

times as the decal advises.

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 determined
which height is best for your lawn. See the Adjustment

Section for details.

Hold control handle down and pull rope firmly to
start the engine.

Set cutting height adjustment lever to middle
setting and mow a single pass on your lawn;

then adjust to desired height for a closer cut.
To mulch insert the mulch plug/cover on the

mower.
Before storing the lawn mower for the winter,

use stabilizer-treated fuel and run the tank dry.

Thirty days before start of the new season,

check the air filter, spark plug and blade on the
lawn mower, and replace if needed.

GasandOil Fill-Up

Service the engine with gasoline and oil as instructed in

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

Check for proper clutch operation by performing the
following procedure before starting the engine:

• With the drive clutch released, push mower
forward. It should move freely. Pull mower

backward. It should move with only a small amount
of resistance.

• If the rear wheels tend to lock up, the clutch may

not be releasing completely. Do not start the engine
until corrections have been made.

• Check the drive cable for severe bends, kinks, or

binding. Also check for grass build-up around the
belt.

StartingEngine

• Attach spark plug wire to spark plug. Make certain

the metal cap on the end of the spark plug is

fastened securely over the metal tip on the spark

plug.

• 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 full 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 pull slightly harder at this point). Let the
rope rewind slowly. Pull rope with a rapid,
continuous, full arm stroke. Keeping a firm grip on
the starter handle, let the rope return to the starter
slowly.

NOTE: See your engine manual packed with your unit
for more detailed instructions.

StoppingEngine

• Release blade control handle to stop the engine

and the blade.

• Disconnect spark plug wire and ground it to a bolt

on the engine.

UsingYourLawn Mower

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 inany 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, or wet grass

may require a narrower cut.
For a healthier 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. Ifmowing has
been delayed and the grass has been allowed to grow
in excess of 4", mulching is not recommended. Mow
using the side discharge to reduce the grass height to 3
114"maximum before mulching.

SECTION6: MAKINGADJUSTMENTS

,_ WARNING: Always stop engine, discon-

nect spark plug, and ground against
engine before performing adjustments.

CuttingHeightAdjustment

Each wheel has a height adjustment lever which
provides cutting height adjustment. When the
adjustment lever is moved from one location to another
the height of cut will be changed. Simply depress the
lever towards wheel and move lever assembly to
desired position. See Figure 9.

All wheels must be placed in the same relative position.
For rough or uneven lawns, move the height
adjustment lever to a higher position. This will help stop
scalping of the grass.

Blade Control Handle and Drive Clutch Control:

Lubricate the pivot points on the blade control handle
and the drive clutch control at least once a season with

light oil. These handles must operate freely in both
directions. See Figure 11.

Wheels: Lubricate the wheels at least once a season
with light oil (or motor oil). If the wheels are removed for

any reason, lubricate the surface of the pivot arm axle
and inner surface of the wheel with light oil.

Chute Deflector or Mulching Baffle: Lubricate the
torsion spring and pivot point periodically with light oil to
prevent any rust or binding.

Engine: Follow the separate engine manual packed
with you unit for lubrication instructions

nect spark plug, and ground against
engine before cleaning, lubricating or
doing any kind of maintenance on your

machine.

• Service air cleaner every 25 hours under normal
conditions. Poor engine performance and flooding

usually indicate that the air cleaner should be

serviced. To service the air cleaner, refer to the
separate engine manual packed with your unit.

• The spark plug should be cleaned and the gap

reset once a season. Spark plug replacement is
recommended at the start of each mowing season.

Clean the engine regularly with a cloth or brush. Keep

the cooling system (blower housing area) clean to

permit proper air circulation which is essential to engine
performance and life. Be certain to remove all grass,

dirt, and combustible debris from muffler area.

Deck

The underside of the mower deck should be cleaned

after each use to prevent a buildup of grass clippings,
leaves, dirt, or other matter. If this debris is allowed to

accumulate, it will invite rust and corrosion, and may
prevent proper mulching, discharge, or bagging. The
deck may be cleaned by tilting the mower and scraping
clean with a suitable tool (make certain the spark plug

wire is disconnected).

IMPORTANT:We do not recommend the use of a
