MEETS CPSC SAFETY REQUIREMENTS
Sears Lawn Walk-Behind Mowers conform to the safety standards of the American National Standards Institute,
Underwriters Laboratories, Inc., and the U.S. Consumer Product Safety Commission. The blade turns when the
engine is running.
MOTOR/BLADE CONTROL LEVER--must be held
against the handle to start and run the motor and blade.
Release to stop the motor and blade.
CORD RESTRAINT--helps prevent disconnection of
extension cord from motor/blade control.
BEFORE USING YOUR LAWN MOWER, AGAIN REFER TO THE "SAFETY RULES" AS SHOWN ON PAGE
2 OF THIS MANUAL. ALWAYS BE CAREFUL.
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
before starting power tool operation or while performing any adjustments or repairs.
We recommend Wide Vision Safety Mask for over spectacles or standard glasses
available at Sears Retail or Catalog Stores.

HOWTO USEYOURMOWER
MOTOR/BLADE CONTROL
WARNING: THE MOTOR/BLADE CON-
TROL ON THIS MOWER 18 INSTALLED TO
MINIMIZE THE RISK OF BLADE CONTACT
INJURY AND IS REQUIRED BY FEDERAL
REGULATIONS, DO NOT UNDER ANY CIR-
CUMSTANCES ATTEMPT TO DEFEAT THE
FUNCTION OF THE MOTOR/BLADE
CONTROL.
The motor/blade control requires the operator to be
behind the handle to start and run the mower. When
the operator releases the control lever, the motor will
stop and an internal brake helps the blade to stop
quickly.
When the operator leaves the operating position to
remove the grass catcher, change the cutting height,
pick up sticks or other objects in the way, the motor
will stop automatically when the motor/blade control
lever is released.
CUTTING HEIGHT ADJUSTMENT
i_l) WARNING: TURN OFF MOTOR AND
DISCONNECT POWER CORD BEFORE AD-
JUSTING THE CUTTING HEIGHT.
The height adjustment knob is located on the left side
of the deck. Turn the knob clockwise to lower cutting
height; turn it counterclockwise to raise the cutting
height. See figure 5.
The cutting height range isapproximately 1" to 3-1/2".
The heights are measured from the ground to the blade
tip with the motor not running. These heights are ap-
proximate and may vary depending upon soil condi-
tions, height of grass and types of grass being mowed.
The average lawn should be cut approximately 1-1/2"
to 2" during the cool season and over 2" during hot
months. For healthier and better looking lawns, mow
often and after moderate growth.
Height
Adjustment
CORDCONNECTION
WARNING: USE ONLY UL APPROVED
OUTDOOR EXTENSION CORD (MINIMUM
16 GAUGE RECOMMENDED),
CORD RESTRAINT
Attach extension cord (not provided with unit) to the
cord restraint as follows. Form a small loop in the ex-
tension cord. Allow enough excess cord to make the
connection to the motor/blade control (approximately
20 inches). S_ip the loop through the slot on the bot-
tom of the cord restraint, and up over the tab, to pre-
vent disconnection from the motor/blade controlduring
operation. Keep the cord restraint as close to the
motor/blade control as possible. See figure 6.
CONNECTION TO THE MOTOR/BLADE CONTROL
WARNING: MAKE CERTAIN MOTOR/
BLADE CONTROL LEVER IS IN OFF
(RELEASED) POSITION.
To attach extension cord to the mower, swing open the
spring-loaded plug retainer located beneath the
motor/blade control. Connect the plug on the extension
cord fully onto the plug on the mower. The mower is
equipped with a polarized AC power plug (one blade
of the plug is wider than the other), which will fit into
the plug on the extension cord only one way. See figure
6, inset. If unable to make a full connection, try revers-
ing the plug on the extension cord. Should the plugs
still fail to fit, contact your service dealer for assistance.
Do not defeat the safety purpose of the polarized plug.
CONNECTION TO THE ELECTRIC POWER SOURCE
Plug the extension cord into any convenient 110-120
volt 60 cycle A.C. outlet or receptacle for your source
of power. This outlet may be located either out-of-doors
or indoors. If an inside receptacle is used, the exten-
sion cord can be taken out either through the doorway
or a window. To avoid blowing fuses, pick an outlet that
is not overloaded. Your mower will operate satisfactorily
on a circuit that is fused for 15 amperes. Do not use
oversize fuses without consulting your power company.

TOSTARTMOTORAND ENGAGEBLADE
Standing behind the unit, lift the motor/blade control
handle with the left forefinger, then pull handle up and
hold it against the upper handle with right hand. See
figure 7.
FIGURE 7.
TO STOPMOTORAND BLADE
1. Release the motor/blade control handle to stopthe
engine and blade. (A high pitched noise will result,
which is the result of deceleration of the electric
motor. Sparking at the top of motor, inside the
motor cover, is also normal during deceleration.)
WARNING: THE BLADE CONTINUES TO
ROTATE FOR A FEW SECONDS AFTER
THE MOTOR IS SHUT OFF. IF MOTOR
DOES NOT COME TO AN IMMEDIATE
STOP WHEN THE MOTOR/BLADE CON-
TROL HANDLE IS RELEASED, CONTACT
AN AUTHORIZED SERVICE LOCATION.
2. Disconnect the power source to prevent acciden-
tal starting while equipment is unattended.
MOWINGTIPS
&WARNING: DO NOT OPERATE THIS
MOWER WITH THE CHUTE DOOR OPEN,
UNLESS THE COMPLETE GRASS CAT-
CHER IS PROPERLY MOUNTED ON THE
MOWER.
Be sure that lawn is clear of stones, sticks, wires, or
other objects which could damage lawn mower or
engine. Such objects could be accidently thrown bythe
mower in any direction and cause serious personal in-
jury to the operator and others.
To prevent electric shock, do not operate the mower
in damp or wet locations.
The length ofthe extension cord you will need depends
on the size of the area to be mowed. See extension
cord information on page 2.
Never mow around the lawn in circles. Always travel
back and forth across the lawn, beginning at the point
nearest the electric outlet where cord is connected. See
figure 8. Cut grass moving away from the outlet so the
cord lies in the cut portion of the lawn, out of the way.
Do not allow extension cord to wrap around trees,
shrubs or other obstacles.

T = Obstacles
In
Outlet
Start Here
FIGURE 8.
When picking up the extension cord,
wind the cord in a series of equal loops
on each side of your hand to prevent
snarling. See illustration at right.
To cut heavy grass, reduce walking speed to allow
more effective cut and distributionof the clippings. For
best results, cut off one-third or less of the total length
of the grass. For ahealthier and better looking lawn,
cut more often and after moderate growth. The lawn
should be cut in the fall as long as there is growth.
WARNING: IF YOU STRIKE A FOREIGN
OBJECT, STOP THE MOTOR. DISCON-
NECT THE POWER SOURCE,
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.

Your mower will work better with a sharp blade.
_b WARNING: DISCONNECT POWER SUP-
PLY BEFORE PERFORMING ANY MAIN-
TENANCE OR ADJUSTMENTS.
TO REMOVE BLADE (See figure 9):
• Turn mower on its side.
• Use a block ofwood between blade and mower deck
to prevent blade from turning when nut is removed.
Protect your hands with gloves and/or wrap blade
with heavy cloth.
•Remove hex nut, and open blade insulator.
• Remove cotter pin, blade nut, flat washer, blade in-
sulator and carriage bolts. Blade

TO REPLACE BLADE (See figure 9):
Use only a Sears authorized replacement blade to get
the best cutting results. Do not use substitutes.
NOTE: All parts must be assembled in the exact order
as shown.
•Fit blade in adapter. Be sure trailing edge of blade
is up towards motor.
•Tighten blade nut securely (30-35 ft. Ibs. torque).
•Re-insert cotter pin and bend ends to secure.
NOTE: If after tightening nut, the slot in nut is not
aligned with hole in shaft, tighten nut just enough to
allow cotter pin insertion.
WARNING: A LOOSE BLADE CAN BE
DANGEROUS.
TO SHARPEN BLADE
NOTE: We do not recommend sharpening the blade--
but if you do, be sure blade is balanced.
•The blade can be sharpened with a file or on a grind-
ing wheel. Do not attempt to sharpen while on the
mower.
Care should be taken to keep the blade balanced.
An unbalanced blade will cause excessive vibration
when running and eventual damage to mower and
motor.
To check blade balance, drive a nail into a beam or
wall. Leave about one inch of straight nail exposed.
Place center hole of blade over the head ofthe nail.
If blade is balanced, itshould 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.
CLEANING
WARNING: DISCONNECT POWER SUP-
PLY BEFORE CLEANING YOUR MOWER.
•Remove any build-up of grass and leaves on or
around motor cover. DO NOT USE WATER.
Clean the underside of your mower after each use
by turning the mower on its side and scraping to
remove any build-up of grass, leaves, dirt or other
matter. DO NOT USE WATER.
•Occasionally use adry cloth to wipe mower,
•Wash grass bag periodically with water. Allow to dry
thoroughly in the shade. Do not use heat.
IMPORTANT: Under normal usage, the grass bag is
subject towear and should be checked periodically. Be
certain any replacement bag complies with the mower
manufacturer's specifications.
SERVICE AND ADJUSTMENTS
