personal injury or damage to your mower.
• Store mower inside. When not in use,
mower should be stored indoors in a
garage, basement, etc. Storage area
should be a dry, locked-up place - out of
reach of children.
• Maintain mower with care. Keep blade
sharp and clean for best and safest
performance. Follow instructions for
lubricating and changing accessories.
DOUBLE INSULATION
Your Mower is DOUBLE INSULATED to
give you added safety. This means that it
is constructed throughout with TWO
separate "layers" of electrical insulation, or
one DOUBLE thickness of insulation
between you and the tool's electrica! system.
Tools built with this insulation system are
not intended to be grounded. As a result,
your mower is equipped with a two-prong
plug which permits you to use extension
cords without concern for maintaining a
ground connection.
NOTE: DOUBLE INSULATION does not
take the place of normal safety precautions
when operating this mower. The insulation
system is for added protection against
injury resulting from a possible electrical
insulation failure within the tool.
41J_.CAUTION: Repair or replace damaged
cords immediately. Use only identical
Craftsman replacement parts.
5
POLARIZED PLUG
To reduce the risk of electric shock, this
mower has a polarized plug (one blade is
wider than the other). This mower must be
used with a suitable polarized 2 wire or 3
wire extension cord. Polarized connections
will fit together only one way. Make sure
that the receptacle end of the extension
cord has large and small blade slot
widths. If the plug does not fit fully into the
extension cord receptacle, reverse the
plug. If it still does not fit, obtain a suitable
extension cord. If the extension cord does
not fit fully into the outlet, contact a
qualified electrician to install the proper
outlet. Do not change the tool plug or
extension cord in any way.
EXTENSION CORDS
Double-insulated tools have 2 wire cords,
and can be used with 2 wire or 3 wire
extension cords. Only round jacketed
extension cords should be used, and we
recommend that they be listed by
Underwriters Laboratories (U.L)
A
_I.WARNING: To prevent electric shock
use only with an extension cord suitable
for outdoor use, such as SW-A, SJOW-A,
SOW-A, STW-A, STOW-A, SJW-A,
SJTW-A or SJTOW-A.
An extension cord must have adequate
wire size (AWG or American Wire Gauge)
for safety, and to prevent loss of power
and overheating. The smaller the gauge
number of the wire, the greater the
capacity of the cable; that is, 16 gauge
has more capacity than 18 gauge. When
using more than one extension to make
up the total length, be sure each individual
extension contains at least the minimum
wire size.
To determine the minimum wire size
required, refer to the chart below: (Refer
to your mower's nameplate to find the
Ampere Rating)
NOTE: Using any other length or rating or
cord will diminish the performance and
possibly the life of the electric motor.

,_.WARNING:
• For your own safety DO NOT use this
mower without either the grasscatcher or
mulch insert in operating position.
• Do not operate the lawnmower if the rear
door is not under spring tension. Take
your mower to the nearest Sears Service
Center for repair.
MULCH INSERT & REAR DOOR
The mulch insert is designed to minimize
the throwing of stones or other objects by
the mower blade backward from under the
mower deck. The mulch insert, along with
the rear door, minimizes the possibility of
accidental foot contact with the blade. DO
NOT operate mower without the mulch
insert and rear door in place.
10
MOWING PROCEDURE
• Inspect area where mower is to be used
and remove all stones, sticks, wire,
bones, and other debris which might be
thrown by the rotating blades.
• Place most of the extension cord close
to the electrical outlet, out of the path of
the mower.
CAUTION: Do not plug extension
cord into receptacle outlet while standing
in water or when hands are wet.
• Begin mowing in the area closest to the
outlet. Always mow forward in a back
and forth pattern across the lawn. Keep
the cord on the cut portion of the lawn.
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" and
wait for blade to stop before 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 unplug the power cord and
turn mower on its side. Using an object
such as a stick, wipe out any
accumulation of grass in the blade area.
Be careful of the sharp edges of the blade.
• If a grasscatcher is used during the fast
growing season, the grass may tend to
clog up at the discharge opening. Turn
the mower "OFF", wait for the blade to
stop and disconnect the power cord
plug. 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
abnormally, turn mower "OFF" and
unplug power cord. Check immediately
for cause. Vibration is a warning of
trouble. Do not operate mower until a
service check has been made.
• ALWAYS turn the mower "OFF" and
unplug the mower when leaving it
unattended even for a short period of
time.
MULCHING
• Your new 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 wil! 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 debris.
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
early 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 cutting height
so that the mower cuts off only the top
one third of the grass blades. If the lawn
is overgrown it will be necessary 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
conditions 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
perpendicular to the first path if it
would require you to mow 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 unplug the mower.
• Raise the rear door and hotd it up.
