IMPORTANT: The mower is
equipped with a blade-brake-clutch
control system which is designed
to stop the mower blades within
three (3) seconds after release of
the Operator Presence Control.
This system will stop the blades
but not the engine. Therefore, you
can disengage the blade drive at
anytime without having to stop and
restart the engine. This feature is
particularly useful when you need
to cross gravel drives or rough ter
rain and you do not want the spin
ning blades to strike stones or hid
den obstacles.

BEFORE STARTING ENGINE
OPERATION
Add Motor Oil
• Only use high quality detergent
oil rated with API service classifica
tion SR SG or SH. Select the oil's
SAE viscosity grade according to
your expected operating tempera
ture. Above 320R use SAE 30;
below 320R use 5W30.
NOTE; Although multi-viscosity oils
(5W30, .10W30 etc.) improve start
ing in cold weather, these oils will
result in increased oil consumption
when used above 320R Check
engine oil more frequently to avoid
possible engine damage from run
ning low on oil.
• Be sure that engine is level. Re
move dipstick (A, Figure 3-10).
• Fill with recommended oil to be
tween “Full” and “Add” marks on
dipstick (approximately 32 oz.).
Pour slowly and do not overfill.
While pouring, stop frequently, re
insert dipstick until it is seated
completely, remove and check oil
level. (Wipe dipstick each time be
fore re-inserting.) Replace dipstick
securely.
• Check oil before each use. Add if
needed.
• Change oil after the first 2 operat
ing hours and every 25 operating
hours thereafter (more often in ex
tremely dusty or dirty conditions).
Fill Fuel Tank
• stop engine and allow it to cool
for three minutes before removing
fuel fill cap (B, Figure 3-10). Do
not check fuel level or add fuel
while indoors.
• Clean area around fuel fill cap
and remove fill cap. Fill gas tank
with clean, fresh unleaded gaso
line. Do not mix oil with gasoline.
• Using a funnel or spout, fill tank
to 1/2 inches below bottom of fuel
tank filler neck to prevent spills and
to allow for fuel expansion.
WARNING: Experience indicates
that alcohol blended fuels (gasohol
or using ethanol or methanol) can
attract m'oisture which leads to
separation and formation of acids
during storage. Acidic gas can
damage the fuel system of an en
gine while in storage. To avoid
problems, the fuel system should
be emptied before storage for 30
days or longer. Drain the gas tank,
start the engine and let it run until
the fuel lines and carburetor are
empty. Use fresh fuel next season.
See STORAGE instructions for ad
ditional information. Never use en
gine or carburetor cleaner products
in the fuel tank or permanent dam
age may occur.
DANGER
Gasoline is highly flammable and its vapors are explosive. Read and fol
low these precautions to help avoid severe personal injury or property
damage.
• Do not remove gas cap or add gasoline if engfne is running or still hot
from operation. Allow engine to cool at least three minutes before
refueling.
• Keep open flame, matches, sparks, or smoking materials away from fuel
tank and fuel container.
• Do not fill fuel tank indoors. After filling, wipe up any spills and move
machine away from gasoline fumes before starting engine. Securely re
place the caps on the fuel tank and fuel container.
• Do not fill fuel tank completely. Fill tank to 1/2” below bottom of filler
neck to provide space for fuel expansion.
• Store gasoline in an approved fuel container and in a well-ventilated area.
Store it safely out of the reach of children.
• Do not store gasoline where vapors may reach an open spark or flame, or
where ignition sources (such as hot water heaters, space heaters, furnaces,
clothes dryers, stoves, electric motors, etc.) are present.

The cutting height can be adjust
ed from 1 to 4 inches by rotating
the Cutting Height Control lever (A,
Figure 3-11).
Choose cutting heights accord
ing to grass conditions and terrain.
In heavy or tail grass, it is usually
better to make the first cut at a
higher setting and then make a
second cut at the desired setting.
When mowing in rough terrain, a
higher setting is recommended as
it will minimize the chances of the
blade striking the ground or hidden
obstructions.

OPERATION
MOWING TIPS AND HINTS
WARNING
To avoid injury or property damage:
• Before mowing, thoroughly inspect area where mower is to be used
and remove all stones, slicks, wires, bones, nails and other foreign
objects.
• Disengage mower blades before crossing gravel drives, roads, or side
walks to prevent blades from throwing stones or other hazardous
objects.
Mow When
Lawn Is Dry
For best results, avoid cutting
grass when it is wet. Wet grass
tends to form clumps which inter
fere with the cutting action. The
best time to mow is in the late af
ternoon or early evening when the
grass is usually dry.
Cut Top 1/3 of
Grass Blades
Cutting more than 1/3 of grass
length may cause the grass to be
come excessively dry. In tall
grass, it may be necessary to mow
at a higher setting and then mow
again at the desired height.
NOTE: The cutting height is criti
cal to achieving a well-groomed
lawn. You should experiment with
various settings to find that “just
right” cutting height.
Vary Cutting Pattern
Vary the cutting pattern from
week to week to help prevent mat
ting of the grass. One week, mow
from north to south, the next week
mow from east to west.: Overlap
several inches when mowing to
obtain an even appearance.
_
1
Mowing on Slopes
Do not mow excessively steep
slopes (see WARNING statement
below). Slow down and exercise
extreme caution when changing di
rection on slopes. Before mowing
on slopes, check the engine oil lev
el and make sure that the level is at
the FULL mark. Maintaining a
FULL oil level is particularly im
portant when operating on slopes
as oil can be drained away from vi
tal engine parts.
WARNING
To avoid injury or property
damage:
• Maximum safe operating
angle is 15°.
• Exceeding maximum safe
operating angle may cause
tipping or loss of footing.
• Do not mow wet slopes.
• Mow across slopes, not up
and down.
• Exercise extreme caution
when changing direction on
slopes.
21
Mulching Leaves
• The mower can also be used to
mow leaves in the fall. The leaf
particles filter down into the lawn
and provide added fertilizer.
• The leaves must be dry in order
to be mulched.
• Use a slower ground speed if the
leaves are not mulched into fine
particles.
• If you mulch oak leaves (which
add acid to the soil), add lime to
the lawn in the spring to reduce the
acidity of the soil.
Keep Mower Blades Sharp
For best mower performance,
keep the blades sharp. A dull blade
will tear, bruise and split the ends
of grass.
Clean Mower Frequently
Clean the underside of the mower
deck frequently to remove grass
build-up.
Precision Trimming
For precision trimming, use the
slowest gear and inch the mower
along by “feathering” the Wheel
Drive Control lever. Or, disengage
the wheel drive by releasing the
Wheel Drive Control so that you
can manually maneuver the mower
(if needed, put the Gear Select
Lever in neutral so that the wheels
turn freely).
Mowing Ditches
If you have to mow ditches, stop
the engine and adjust the cutting
height to its highest setting. Mow
in the direction of the ditch. Mow
both sides of the ditch first, and
then mow the bottom. When
mowing ditches, watch out for
cans, bottles, or other debris.
Page 22
OPERATION
BUDE BRAKE CONTROL
TEST
When the Operator Presence
Control is released during opera
tion of the mower, the engine does
not stop, but the blades should
stop within three (3) seconds. The
following test provides a visual test
of whether the Blade Brake Control
System is functioning. Perform
this test before each use of the
mower.
WARNING
To avoid personal injury or
property damage, make sure
that the mower is on grass,
and that the test area is clear
of foreign objects and by
standers before you begin the
Blade Brake Control Test.
It the Operator Presence Con
trol or the Blade Drive Control
are not adjusted correctly, the
blades may continue to rotate
after release of the Operator
Presence Control. If the
blades do not stop within
three (3) seconds of release
of the Operator Presence Con
trol, move the Engine Throttle
Control to the STOP position,
disconnect the spark plug
wire, and move the wire away
from the spark plug. Do not
operate the mower until the
Blade Brake Control System
f .TJ
has been repaired.
Failure to do this could result
in personal injury or property
damage.
1. Park mower on a portion of
lawn which has not been recently
mowed. ■
2. Set the cutting height so the
mower cuts 1/3 of the grass height.
3. Start the engine.
4. Press the Operator Presence
Control down against the handle
bar grip and push the Blade Drive
Control fully fonward until it stays in
the engaged position.
5. Put the Gear Select Lever in
the No. 1 setting.
6. " Engage the wheels with the
Wheel Drive Control and drive the
mower for several feet. Then re
lease the Operator Presence Con
trol.
A. Look at the lawn just mowed.
The lawn should be cut up to
the point where the Operator
Presence Control was released.
B. Press the Operator Presence
Control against the handlebar
grip but DO NOT re-engage the
Blade Drive Control. Drive the
mower fonward for several more
feet. Release the Operator
Presence Control and look at
the lawn. The grass should
NOT have been cut. This indi
cates that the Operator Pres-
■ ence Control has disengaged
the blade drive and stopped the
blades.
7. If the mower cuts the grass in
Step 6-B, the Operator Presence
Control is NOT disengaging the
blade drive. Immediately stop
the engine, disconnect the
sparkplug wire, and move the
wire away from the spark plug.
8. Do not use the mower until the
Blade Brake Control System has
been inspected, adjusted or re
paired by a Sears Service Center.

NOTE; Do not clean spark plug in
machines which use abrasive grit.
Clean spark plug by scraping or
wire brushing, or washing with a
commercial solvent. '
CARBURETOR
The carburetor is adjusted at the
factory. It should not need to be
reset. If black exhaust is noted,
check the air cleaner first. An
over-rich mixture is usually caused
by a poorly serviced or clogged air
cleaner element, not an improperly

WHEEL DRIVE BELT
ADJUSTMENT
The wheel drive belt requires an
adjustment if loss of drive beit ten
sion (slippage) occurs. This is
most noticeable when more trac
tion is required (such as going up
slopes).
To Test Wheel Traction
1. Park machine on a paved (con
crete, etc.) surface with front edge
up against a sturdy wall, fence,
etc.
2. Put Gear Select Lever in No. 1
setting.
IMPORTANT: Do not park against
a painted or sided wall. Testing
the wheel drive system requires
machine to be forcibly pushed
against wall. Damage to paint or
siding could result.
SERVICE AND ADJUSTMENTS
3. With engine running, and ma
chine placed firmly up against
wail, hold down Operator Pres
ence Control and fully engage
wheel drive by squeezing Wheel
Drive Control until it contacts
handlebar.
4. Wheels should slip on paved
surface. If they do not, an adjust
ment is required.
To Adjust Wheel Drive Beit
1. Stop engine, wait for all parts
to stop moving, and disconnect
spark plug wire.
2. Remove cotter pin (A, Figure
5-12A) from upper end of Wheel
Drive Control rod. Slide rod out of
lever assembly.
3. Loosen jam nut (D, Figure
5-12).
Figure 5-12: Wheel drive belt adjustment
4. Thread rod (E. Figure 5-12) one
or two turns clockwise for more
tension or counterclockwise for
less tension.
5. Insert rod back into hole in
Wheel Drive Control lever and In
stall cotter pin. Bend ends of cot
ter pin to secure.
6. Retest wheel traction. Repeat
adjustment procedure, if neces
sary. Most comfortable operation
will be obtained when the adjust
ment allows the lever to just make
contact with the handgrip as suffi
cient wheel traction is achieved.
When adjustment is complete,
tighten jam nut (D) firmly against
block (B).
