• Avoid mowing when the grass is wet
from rain or dew-soaked
• Cut your lawn frequently, especially dur-
ing high growth periods.
NOTE: You should recharge your mower
after each use, regardless of the position
of the battery gauge needle. Frequent
charging will not harm your battery, and
will ensure that the battery is fully charged
and ready for its next u_e,
SAFETY SHIELD AND REAR DOOR
Your Cordless Mulching mower has a
gauge to provide you with information on
your battery state of charge. While oper-
ating the mower, the gauge constantly
senses and displays the battery condition
as follows:
• When the needle is pointing in the
green area (1), the battery is in a highly
charged condition.
• When the needle is pointing in the red
area (2), the battery charge is depleted.
* Before using your mower for the first
time, charge the battery overnight to
ensure that it is fully charged. When
you first start your mower, the battery
gaugeIhould pointInthe greenarea,
Indicating a fully charged battery.
• As you use your mower, you will notice
that the needle in the battery gauge
drops slowly as the battery discharges.
• While cutting grass with your cordless
mower, it is normal for the battery gauge
needle to fluctuate somewhat as the
cutting conditions change.
• When your battery gauge needle points
consistently in the red area, your battery
is now discharged, even though the
mower may still be capable of cutting
grass. Continuing to operate your
mulching mower with the battery in this
discharged condition may reduce the life
and performanceof yourbattery,
The following suggestions will help you
to obtain optimum run time from your
cordless mower:
• Slow down in areas where the grass is
especially long or thick, or raise the cut
height.
• When mulching, avoid cutting more than
1-1/2 inches off the grass.
This safety shield (1) is designed to mini-
mize the throwing of stones or other
objects by the mower blade backward
from under the mower deck. The shield,
along with the rear door (2), minimizes the
possibility of accidental foot conta¢t with
the blade. DO NOT operate mower with-
out the safety shield and rear door in
place.
WARNING:
• For your own safety DO NOT use this
mower without either the grasscatcher or
mulch insert in operating position.
. Do not operate the mower If the springin
the rear door loses itstension. Take your
lawnmower to the nearest Sears Service
center for repair.

MOWING TIPS
• Mow across the face of slopes, never
up-and-down. Exercise extreme caution
when changing direction on slopes. Do
not mow excessively steep slopes.
Always maintain good footing.
• Release switch to turn mower "OFF"
when crossing any graveled area (stones
can be thrown by the blade).
, Set mower at highest cutting height .........
when mowing in rough ground or in tall
weeds.
• From time to time turn off mower and
wait for the blade to come to a complete
stop. Then remove the safety key and
turn mower on its side. Using an object
such as a stick, wipe out any accumula-
tion of grass in the blade area. Be care-
ful of the sharp edges of the blade.
• If grasscatcher is used during the fast
growing season, the grass may tend to
clog up at the discharge opening. Turn
the switch "OFF" and remove the safety
key. Remove the catcher and shake the
grass down to the back end of the bag.
Also clean out any grass or debris which
may be packed around the discharge
opening, Replace the grass catcher,
Clean often in wet, spring grass.
• If mower should start to vibrate abnor-
mally, turn mower "OFF" and remove
safety key. Check immediately for cause.
Vibration is a warning of trouble. Do not
operate mower until a service check has
been made.
• ALWAYS turn the switch "OFF" and
remove safety key when leaving
mower unattended even for a short
period of time,
MULCHING
• Your mower is designed to re-cut the
grass clippings many times and reduce
them in size so that, as they fall into the
lawn, they will disperse into the grass
and not be noticed. Also, the mulched
grass will biodegrade quickly to provide
nutrients to the lawn.
° Your mower was shipped with the Mulch
Insert installed.
MULCHING MOWING TIPS
° For best performance, keep the mower
housing free of built-up grass and trash,
Clean after each use. See CLEANING In
the maintenance section of this manual.
• Avoid cutting the lawn when it is wet.
Wet grass tends to form clumps which
interfere with the mulching action. The
best time to mow your lawn is in the late
afternoon. At this time the grass is dried
and the newly cut area will not be
exposed to the direct sun.
• For best results, adjust the mower cut-
ting height so that the mower cuts off
only the'top one-thirdof the grass blades.
If the lawn is overgrown it wil! be neces-
sary to increase the cutting height to
reduce the pushing effect and reduce
overloading the motor. For extremely
heavy mulching make narrower cuts and
mow slowly.
• Certain types of grass and grass condi-
tions may require that an area be
mulched a second time to completely
hide the clippings. When doing a second
cut, mow across or perpendicular to the
first cut path. DO NOT mow perpendic-
ular to the first path if it would cause
mowing across a hill.
• Change your cutting pattern from week
to week. Mow north to south one week
and east to west the next week. This will
help prevent matting and graining of the
lawn.
TO REMOVE MULCH INSERT
• Shut the mower off, wait until the blade
stops and remove safety ,key.
• Raise the rear door and hold it up.
• Locate your hand in the handle pocket of
the mulch insert, lift and pull out the
mulch insert completely.
• The rear discharge door is spring
loaded. When you release it the door will
return to the closed position.
TO INSTALL MULCH INSERT
• Shut the mower off, wait until the blade
stops, and remove safety key.
• Raise the rear door and slide the mulch
insert into the discharge opening until it
is firmly in contact with the deck.
° Release the rear door.

TO REMOVE BLADE
• Release Operator Presence Control
Switch to turn mower off, wait for the
blade to stop, and remove safety key.
• Cut a two foot length of 2x4 wood and
use it to keep blade from turning while
removing blade nut.
• Wear gloves, position wood, and loosen
nut counterclockwise as shown. Remove
nut.
• Remove square steel washer, plastic
insulator washer and blade.
TO REPLACE BLADE
• Place blade on shaft so that the blade
edges are parallel with the flat sides of
the shaft. Make sure you place the blade
so that its cutting edges will face the
ground when the mower is running.
• Place plastic insulator washer on shaft
so that two of the washer's raised edges
fit over the edges of the blade.
,. Place square steel washer on shaft so
that flat sides of hole in washer are par-
allel with flat sides of shaft.
Place blade nut on shaft. Make sure all
parts stay aligned. Position wood to keep
shaft from turning. Securely tighten blade
nut clockwise to 20-30 ft. Ibs.
TO SHARPEN BLADE
" l-ltte
• Keep blade sharp for best mower perfor-
mance. A dull blade does not cut grass
evenly.
° Wear proper eye protection.
13
@
• Sharpening the blade twice during a
mowing season is usually sufficient
under normal circumstances. Sand caus-
es the blade to dull fast. If your lawn has
sandy soil, more frequent sharpenings
are required,
• Replace bent or damaged blade immedi-
ately.
To sharpen blade:
GENERAL MOWING TIPS
During the spring when the grass is lush,
your mower may cut less than in mid-sum-
mer when the grass is light and dry.
Here are some helpful hints to get the
most from your Craftsman cordless
power mower and to keep your lawn
looking beautiful
• Lawns should first be mowed in the
• Make sure blade remains balanced, spring when the grass is about 2 1/2 to 3
inches high. Mowing too early restricts
° Sharpen blade at the original cutting ttle grass root systems which renew
angle.
• Sharpen cutting edges on both ends of
blade, removing equal amounts of
material from both ends.
themselves every spring. New grass
should be clipped when it is about 2 1/2
inches high.
• Do not remove too much grass blade
surface at one time - never more than
1/3 of the leaf height during each cutting.
Cutting too close "shocks" sensitive
grass blades, resulting in a shallow root
system and making it more difficult for
your lawn to reach water in the soil.
; Lawncare experts say that excessively
close cutting Is responsible for much of
the difficulty experienced on many lawns.
The depth and strength of the roots of
grass are almost exactly proportional to
its growth. Grasses of mature lawns
often are seriously injured when mowed
• Secure blade in a vise as shown in fig-
ure below.
• Wear safety glasses and be careful not
to cut yourself.
• Carefully file the cutting edges of the
blade with a fine tooth file or sharpen-
Ing stone.
Check balance of blade. See instructions
for blade balancing.
After blade is sharpened and balanced
replace blade on mower and tighten
securely.
TO BALANCE BLADE
Check balance of blade by placing cen-
ter hole in blade over a nail or screwdriv-
er shank, clamped horizontally in a vise.
If either end of the blade rotates down-
ward, file that end. Blade is properly bal-
anced when neither end drops.
shorter than 1 1/2 inches, and a height
of 1 1/2 to 2 inches is preferred on large
lawns.
• Mow your lawn when it is dry to avoid
clumping of wet grass. If you have a
choice, late afternoon is the ideal time
for mowing, not only because the grass
is dry, but also because the sensitive
new cut area of the grass will not be
exposed to intense sunlight.
• Keep the mowing blade sharp for a nice
clean cut, This Improves the mower's
performanceand snhanoe,the look of
your lawn, A dull blade bruises and shat-
ters the tips of the grass. This impairs
the healthy growth of your lawn and
increases susceptibility to turf diseases.
If the grass tips are bruised it causes a
brownish color and gives your lawn an
unhealthy appearance, A dull blade may
also pull up young seedlings,
• Try to mow your lawn at the same (con-
sistent) cutting height. While there are
times when you should vary the cutting
height with the changing seasons, a con-
sistent cutting height produces a healthi-
14
er, lovelier lawn with generally fewer
weeds. Mow more frequently during peri-
ods of fast growth. Frequent cutting
ensures that the lower, less attractive
portion of the grass will not show.
• If'your lawn has grown too long, (a vaca-
tion, for example, may interrupt your cut-
ting schedule) mow at a cutting height
one or two positions higher than normal.
A second pass at "normal" cutting height
a few days later will put your lawn back
on schedule, Changing the cutting height
Is a simple matter with the One Touch
Wheel Height Adjustment, which simulta-
neously adjusts all four wheels at once.
• During the spring and fall, (or after an
interruption to the cutting schedule) the
grass will be longer and thicker. If the
motor continually slows down while cut-
ting, try setting the wheels for a higher
cutting height. Excessive motor loading
can result in uneven cutting, quicker dis-
charge of the battery, and can cause the
circuit breaker to trip, which stops the
motor.
• Three good ideas to enhance your
lawn's appearance: Vary the mowing
direction frequently; mow horizontally on
hillsides; (this is also a good safety prac-
tice) and do not forget to overlap the
mowing path on each pass.
•.Always mow grass so that clippings are
discharged onto cut lawn. This will keep
your lawn looking fresh by avoiding "Cut
Grass" build-up which will eventually
brown and appear ugly, This method
also preserves your battery charge,
ensuring you get the most from your
Craftsman Cordless Power Mower.
• During the spring and fall seasons when
the grass is longer and thicker, you can
use your mower without it being fully
recharged. (i.e. green charge indication
light is on). This will enable you to per-
form short cutting tasks, but we don't
recommend this be done frequently. The
battery.and mower perform much better
if charged fully.

GENERAL RECOMMENDATIONS
• Always observe safety rules when per-
forming any maintenance.
• The warranty on this lawn mower does
not cover items that have been subject-
ed to operator abuse or negligence. To
receive full value from the warranty,
operator must maintain mower as
instructed in this manual.
• Once a year check blade for wear.
• Follow the maintenance schedule in this
manual.
• Before each use:
• Check for loose fasteners.
LUBRICATION
No lubrication is required.
IMPORTANT: Do not oil or grease plastic
wheel bearings. Viscous lubricants will
attract dust and dirt and will shorten the
life of the self-lubricating bearings. If you
feel they must be lubricated, use only a
dry, powdered graphite tube lubricant
sparingly.
TIRES
, Keep tires free of gasoline, oil or insect
control chemicals which can harm rub-
ber.
PRODUCT SPECIFICATIONS
• Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
BLADE CARE
For best results, mower blade must be
kept sharp. Replace bent or damaged
blades.
CLEANING
• TURN MOWER OFF, let the blade
come to a stop and then remove safe-
ty keyl
° Use only mild soap and a damp cloth to
clean the mower. Clean out any clippings
which may have accumulated on the
underside of the deck.
PREVENTING CORROSION
• Fertilizers and other garden chemicals
contain agents which greatly accelerate
the corrosion of metals. If you mow in
areas where fertilizers or chemicals have
been used, the mower should be
cleaned immediately after use.
• CAUTION: DO NOT pour or spray water
on the mower.
• Do not store the tool on or adjacent to
fertilizers or chemicals. Such storage can
cause rapid corrosion.

BATTERY
The battery in your mower is a recharge-
able 24 volt sealed lead acid battery. To
get the maximum battery life, we rec-
ommend the following:
• Fully recharge battery prior to initial use.
• Recharge battery immediately after each
use.
• Recharge battery continuously when
mower is not in use.
• Always charge battery indoors in a dry,
protected place
• DO NOT charge in extreme hot or cold
temperatures. Charge mower battery in a
location where temperature is more than
41_F(5_C) but less than 104gF (40_C)
REAR DEFLECTOR
The rear deflector, attached between the
rear wheels of your mower, is provided to
minimize the possibility that objects will be
thrown out of the rear of the mower into
the operator mowing position. If the
deflector becomes damaged, it should be
replaced.
BATTERY REPLACEMENT
If properly maintained, the expected bat °
tery life is 4-7 years. If battery replace-
ment becomes necessary, take your
mower to a Sears Service Center for
replacement.
HANDLE ADJUSTMENT
To adjust handle refer to "Handle
Adjustment" in Operation section of this
manual.
TO ADJUST CUTTING HEIGHT
To adjust cutting height refer to "Adjust
Cutting Height" in Operation section of this
manual.
Immediately prepare your lawn mower for
storage at the end of the season or if the
unit will not be used for 30 days or more.
LAWN MOWER
When lawn mower is to be stored for a
period of time, clean it thoroughly, remove
all dirt, grease, leaves, etc. Store in a
clean, dry area.
• Clean entire lawn mower (See "CLEAN-
ING" In the Maintenance section of thts
manual).
• Be sure that all nuts, bolts, screws, and
pins are securely fastened. Inspect mov-
ing parts for damage, breakage and
wear. Replace If necessary.
BATTERY
, Recharge the battery to a full charge. Do
not store mower with a discharged bat-
tery. Battery failure will occur in a very
short time if mower is stored without hav-
ing a full charge. We recommend that
you charge battery continuously while in
storage and during off season.
HANDLE
You can fold your lawn mower handle for
storage.
* Ensure that the power cord has been
unplugged.
• Loosen both handle knobs.
• Carefully fold the handle forward over
the mower.
CAUTION; DO NOT pinch cable
between handle and meter shroud.
