HOWTOUSEYOURMOWER ............................................................................................................................................................
ENGaNESPEEDSELECTOR
The en_line speed is controlled by a lever (red knob)
iocatedon the right side of the engine_ "HIGH" posi-
tion is for' starting engine, normal cutting and better
grass bagging. "LOW" position is for light cutting,
trimming and fuel economy (See Fig. 5).
DRIVE CONTROL
o Self-propelling is controlled by holding the
operator presence control bar down to the ham
die and pushing the drive control lever forward
until it clicks; then release the lever (See Fig 6)_
o Forward motion will stop when the operator
presence control bar is released. To stop forward
motion without stopping the engine, release the
operator presence control bar' slightly until the
drive control disengages_ Hold operator presence
control bar down tohandle to continue mowing
without self-propelling_
o To keep drive control engaged when turning cor-
ners, push down on handle and lift front wheels
off .qround while turning mower_
NOTE: When your mower is new, the drive wheels
may rotate without the drive control engaged when
the wheels are lifted off the ground. This is normal
and should stop after the first few hours of operatiom
TO EMPTYGRASSCATCHER
o To remove grass catcher, release operator
presence control bar to stop engine_
o Lift up rear' door' and remove the grass catcher
by the handle (See Fig. 7).
NOTE: Do not drag the bag when emptying; it will
cause unnecessary wear.
TO ADJUSTCUTTINGHEIGHT
o Raise wheels for low cut and lower wheels for
high cut.
o Wheels are set in low cut for shipping. Adjust cut-
ting height to suit your requirements_ Medium
position is best for most lawns.
o To change cutting height, squeeze adjuster lever
toward wheel. Move wheel up or' down to suit
your requirements. Be sure all wheels are in the
same setting (See Fig. 8)_
BEFORESTARTINGENGINE
OIL:
oRemove engine oil cap with dipstick and fill to the
"FULL" line on the dipstick. Use about one (1)
pint or 1t2 liter of Sears 30W oil or equivalent.
SAE 10W 30 oil can also be used° DO NOT

use SAE 10W 40 oil. The total oil capacity of
your engine is 21 oz. or 0.62 liters° Fill only to
the full line on the dipstick. DO NOT overfill. 1'he
first fill on a new engine uses about one (1) pint
of oil. Check oil level and add oil as needed to
bring to the proper" level.
o Pour oil slowly - DO NOT overfill.
GAS:
oFill gasoline tank with fresh, clean unleaded
gasoline. DO NOT USE PREMIUM GASOLINE.
BE CAREFUL NOT TO OVER FILL TANK (SEE
FIG,4).
BEFORESTARTINGENGINE (CONT'D) ................................................................................................... _o...........................!
WARNING: Experience indicates that alcohol blend-
ed 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.
To avoid engine problems, the f_Jelsystem shouldbe
emptied before storage for 30 days or longer. Drain
the gas tank, start the engine and let it run until the
fuel/ines and carburetor are empty. Use fresh fuel
next season. See Storage Instructions for additional
information. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may
occur.
TO STARTENGINE
oTo start a cold engine, push primer five (5) times
before trying to start. Use a firm push_ This step
is not usually necessary when starting an engine
which has already run for a few minutes.
oPush engine speed selector lever forward to
"HIGH" positiom
o Hold operator presence control bar down to the
handle and pull starter handle quickly. Do not
allow starter rope to snap back.
oTo "STOP" engine, release operator presence
control bar°
NOTE: In cooler weather it may be necessary to
repeat priming steps, in warmer weather over prim-
ing may cause flooding and engine will not start_ If
you do flood engine wait a few minutes before at-
tempting to start and DO NOT repeat priming steps°
MOWINGTIPS
Under certain conditions, such as very tall grass,
it may be necessary to raise the height of cut to
reduce pushing effort and to keep from
overloading the engine and leaving clumps of
grass clippings.
LOWER WHEELS _ RAISE WHEELS
FOR HIGH CUT FOR LOW CUT
FIG. 8
°For extremely heavy cutting, reduce the width of
cut and raise the rear of the mower housing one
(1) wheel adjuster setting higher than the front for
better discharge of grass.
oWhen using a rear bagging mower in moist,
heavy grass, clumps of cut grass may not enter
the grass catcher. Reduce ground speed (pushing
speed) and/or run the mower over the area a se-
cond time.
oFor better grass bagging and most cutting con-
ditions, the engine speed should be set in the
"HIGH" (fast) position.
o If a trail of grass clippings is left on the right side
of a rear bagging mower, mow in a clockwise
direction with a small overlap to collect the clip-
pings on the next pass.
_, For side discharge mowers, cutting in a counter-
clockwise direction, starting at the outside of the
area to be cut, spreads grass clippings more even-
ly and puts less load on the engine_ To keep clip-
pings off of walkways, flower beds, etc., make
the first cuts in a clockwise direction.
Pores in cloth grass catchers can become filled
with dirt and dust with use and catchers will col-
lect less grass° To prevent this, regularly hose cat-
cher off with water and let dry before using.
GENERALRECO_|NDATiON
o Once a year you should replace the spark plug,
air filter', and check blade for wear° Anew spark
plug and air filter assures proper air-fuel mixture
andhelps your engine run better and last longer_
oYou should check all fasterners and be sure they
are tighL
Follow the Service Recommendation Schedule on
page 16.
BLADE/BLAD[FLANGEC&R[
Your mower will work better with a sharp blade.
CAUTION: DISCONNECTSPARK PLUG WIRE
FROM SPARKPLUGAND PLACEWIRE WHERE
IT CANNOT COME IN CONTACTWITH THE
SPARKPLUG.
TO REMOVE BLADE:
Turn mower on its side. Make sure air filter and
carburetor are up_
Use block of wood between blade and mower
housing to prevent blade from turning when nut
is removed. Protect your hands with gloves andtor
wrap blade with heavy cloth.
•Remove nut by turning counter<lockwise. Use a
15116" box or open-end wrench.
NOTE: Check tab in blade flange after removing, if
tab is damaged, replace iL It must be in good con-
dition for the blade to work properly. We recom-
mend that a new blade nut be used each time blade
is removed.
TO REPLACE BLADE:
oPut blade flange on engine crankshaft with tab
in slot (See Fig. 9).
oFit blade on crankshaft in the blade flange. Be
sure the word "TOP (stamped on blade) is toward
engine.
oPlace flat washer, two (2) formed washers and
nut on crankshaft (See Fig. 9).
Use block of wood to holdblade and tighten nut
clockwise. The recommended torque is 70-75 fL-
Ibs. Torque wrenches are avalable at most Sears
stores and through the catalog.
CAUTION: A LOOSEBLADECAN BEDANGEROUS_
,_ AND MAY MAKE THE ENGINE HARD TO START!
Use only aSears authorized replacement blade to
get the best cutting results_
FIG. 9
NOTE: We do not recommend sharpening btade - but
if you do, be sure the blade is balanced,
TO SHARPEN BLADE:
oThe blade can be sharpened with a file or on a
grinding wheel. Do not attempt to sharpen while
on the mower.
o Care should be taken to keep the blade balanc-
ed. An unbalanced blade will cause excessive
vibration when running and eventual damage to
mower or engine.
o To check blade balance, drive a nail into a beam
or wail Leave about one inch of the straight nail
exposed. Place center hole of blade over' the head
of the nail. If blade is balanced, it should remain
in a horizontal position. If either end of the blade
moves downward, blade is not balanced.
Sharpen the heavy end until the blade is
balanced_

MAINTENANCE
DRIVEWHEELS
NOTE: Check front drive wheels each time before you
mow to be sure they move freely.
The wheels not turning freely means trash, grass, cut_
tings, etc. are in the drive wheel area and must be
cleaned to free drive wheels_
If necessary to clean the drive wheels, check both
front wheels.
oRemove hub caps, hairpin cotters and washers_
oRemove wheels from wheel adjusters_
oRemove any trash or grass cuttings from inside
the dust cover, pinion andtor drive wheel gear
teeth.
•Put wheels back in place.
•If after cleaning, the drive wheels do not turn free-
ly, contact your nearest Sears Service Center.
