Your lawn mower was built to be operated according to the rules for safe operation in this
DANPER- power equipment, carelessness or error on the part of the operator
' can result in serious injury. If you violate any of these rules, you may cause serious injury to
yourself or others.
This unit is equipped with an internal combustion engine and should not be used on or near any unimproved
forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a
spark arrester meeting applicable local or state laws (if any), if a spark arrester is used, it should be
maintained in effective working order by the operator.
In the State of California the above is required by law (Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the

GENERAL OPERATION
Read this owner’s guide 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.
Your rotary mower 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.
Never allow children under 14 years old to operate
a power mower. Children 14 years old and over
should only operate mower under close parental
supervision. Only responsible individuals who are
familiar with these rules of sate operation should
be allowed to use your mower.
Keep the area of operation clear of all persons,
particularly small children and pets. Stop engine
when they are in the vicinity of your mower to help
prevent blade contact or thrown object injury.
Although the area of operation should be
completely cleared of foreign objects, an object
may have been overlooked and could be
accidentally thrown by the mower in any direction
and cause serious personal injury to the operator
or any others allowed in the area.
I
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 picked up and thrown by the mower in any
direction and cause serious personal injury to the
operator or any others allowed in the area. Plan
your mowing pattern to avoid discharge of material
toward roads, sidewalks, bystanders and the like.
To help avoid a thrown object's injury, keep
children, bystanders and helpers at least 75 feet
from the mower while it is in operation.
Always wear safety glasses or safety goggles
during operation or while performing an adjustment
or repair, to protect eyes from foreign objects that
may be thrown from the machine in any direction.
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. Do not wear loose fitting clothes or
jewelry. They can be caught in moving parts. Never
operate a unit in bare feet, sandals, slippery or light
weight (e.g. canvas) shoes.
Do not put hands or feet near or under rotating
parts. Keep clear of discharge opening at all times
as the rotating blade can cause injury.
Many injuries occur as a result of the mower being
pulled over the foot during a fall. Do not hang on to
the mower if you are falling; release the handle
immediately.
Never pull the mower toward you while you are
walking. If you must back the mower away from a

Using Your Lawn Mower
Your mower is designed to operate as a mulching or a
side discharge unit.
• For converting from a mulcher to a side
discharge unit, refer to instructions on page 8.
Do not operate mower without the mulching
deflector or the grass catcher properly
installed and tightly secured.
• Be sure that lawn is clear of stones, sticks,
wire, or other objects which could damage lawn
mower or 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 or wet grass may require a
narrower cut. Blade speed should be adjusted
to the condition of the lawn.
• The best mowing pattern is one that allows the
clippings to discharge towards the uncut part of
the lawn. This permits recutting of the clippings
to further pulverize them. When cutting high
weeds, discharge towards cut portion, then
recut at right angles to first direction.
• For a healthy lawn, always cut off one-thiid or
less of the total length of the grass. Lawn should
be cut in the fall as long as there is growth.
• Thlsmoweris designed to be ope rated at full
throttle to give you the best cut and do the

blade, protect hands by using heavy
A
gloves or a rag to grasp the cutting
blade.
Disconnect spark plug wire from spark plug.
Turn mower on its side making sure that the air
filter and the carburetor are up to check the
blade. If the blade needs to be serviced, refer
to the instructions on blade care in the “Service
& Adjustments" section of this manual.
Wheels
• Lubricate the wheels at least once a season
with light oil or engine oil. Also, if the wheels are
removed for any reason, lubricate frie surface
of the axle bolt and the inner surface of the
wheel with light oil.
Blade Control Handle
• Lubricate the pivot points on the blade control
handle and the brake cable at least once a
season with light oil. The blade control handle
must operate freely in both directions. For
complete lubrication chart, see Figure 15.
Chute Deflector
• Lubricate the torsion spring and the pivot point
on each end of the chute deflector using a light
oil. This will prevent rusting and ensure that the
deflector, which is a safety device, can always
work properly.

crankshaft and the inner surface of the blade
adapter with light oil. _
• Install the blade adapter on the crankshaft with
the “star” away from the engine. See Figure 16.
To Sharpen Blade:
The blade can be sharp>ened with a file or on a grinding
wheel. Do not attempt to sharpen while on the mower.
• Follow the original angle of grind as a guide.
Make sure that each cutting edge receives an
equal amount of grinding to prevent an
unbalanced blade.
NOTE: An unbalanced blade will cause excessive
vibration when rotating at high speeds, may cause
damage to the mower and couid break, causing
personal injury.
• Test the blade by balancing it on a round shaft
screwdriver or a blade balancer. See Figure 17.
• If the blade is not balanced, remove metal from
the heavy side until it balances evenly.

Engine Adjustments
A WARNING: Do not make unnecessary
adjustments on the engine. Factory settings
•• are satisfactory for most conditions.
If any adjustments are made to the engine
while the engine is running, keep clear of all
moving parts. Be careful of heated
surfaces and muffler. Keep your hands
away from these parts. -
Carburetor
The carburetor has been pre-set at the factory and
should not require adjustment.
• If the engine on your mower does not operate
properly due to suspected carburetor problems,
take your lawn mower to your nearest SEARS
service center.
• Engine performance may be affected in altitudes
above 4000 feet. To improve engine
. performance, install a high altitude adjustment
kit, available at the SEARS service center.
NOTE; A dirty air cleaner will cause an engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor.

• If you believe the engine is running too fast or
the factory setting can be dangerous. Do not
attempt to increase engine speed or it may
result in personal injury. Changing of engine
governed speed will void engine warranty.
too slow, take your lawn mower to the nearest
SEARS service center.
Adjusting Handle Height
Your mower is shipped with the handle in the higher
height position. To lower the handle height, proceed
as follows.
• Remove the starter rope from the rope guide.
• Remove the upper handle by removing the hand
knobs and carriage bolts. Lay the upper handle
out of the way, being careful not to bend or kink
the cable.
• Remove the hairpin clip from the weld pin on the
handle bracket on each side of the lower handle.
See Figure 18 inset. Press out on the legs of the
lower handle. Remove lower handle from the
mower.
• Turn the lower handle around so the notch on
the bottom of the lower handle is facing forward
as shown in Figure 18. Reassemble, placing the
bottom hole on the handle over the weld pin in
the handle mounting bracket.
• Reassemble the upper handle to the lower
handle.
• Place the hairpin clips in the inner holes in the
weld pins and attach the starter rope as
instructed in the Assembly section. See Figure
18 inset.
Adjusting Cutting Height
IMPORTANT; All wheels must be placed In f/ie same
relative position.
• Raise the mower wheels for low cut and lower the
wheels for high cut. For rough or uneven lawns,
move the height adjustment lever to a higher
position. This will help stop scalping of the
grass.
There is an adjusting plate and thumb lever at each
wheel position to adjust the cutting height. Each
adjusting plate heis nine height positions. Height of cut
will change if you move the thumb lever from one hole
to another.
• Simply depress the lever towards wheel and
move the wheel and lever assembly to the
desired position. See Figure 19. All wheels
must be placed in the same relative position for
unifomn cutting height.
• For rough or uneven lawns, move the height
adjustment handles to positions which will give
a higher cutting height. Both front and rear
handles must be placed in the same relative
position.

IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as
carburetor, fuel filter, fuel hose, or tank during
storage. Also, experience indicates that alcohol
blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to
separation and formation of acids during storage.
Acidic gas can damage the fuel system of an engine
while in storage.
Note: Do not drain carburetor if using fuel stabilizer.
WARNING: Never use engine or
