,_ WARNING: Read and understand all instruc-
tions. Failure to follow all instructions listed
below may result in electric shock, fire and/or
serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
•Keep your work area clean and well lit. Clut-
tered benches and dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools
may create sparks which may ignite the dust or
fumes.
•Keep bystanders, children, and visitors away
while operating a power tool. Distractions can
cause you to lose control.
Electrical Safety
•Double insulated tools are equipped with a
polarized plug (one blade is wider than the
other). This plug will fit in a polarized outlet
only one way. If the plug does not fit fully in the
outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a
polarized outlet. Do not change the plug in any
way. Double insulation [] eliminates the need for
the three-wire grounded power cord and grounded
power supply system,
•Avoid body contact with grounded surfaces,
such as pipes, radiators, ranges, and refrigera-
tors. There is an increased risk of electric shock if
your body is grounded.
•Don't expose power tools to rain or wet condi-
tions. Water entering a power tool will increase
the risk of electric shock.
•Do not abuse the cord. Never use the cord to
carry the tools or pull the plug from an outlet. 2
Keep cord away from heat, oil, sharp edges, or
moving pads. Replace damaged cords Immedi-
ately. Damaged cords increase the risk of electric
shock.
When operating a power tool outside, use an
outdoor extension cord marked "W-A" or "W".
These cords are rated for outdoor use and reduce
the risk of electric shock.
Personal Safety
•Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use tool while tired or under the influ-
ence of drugs, alcohol, or medication. A mo-
ment of inattention while operating power tools
may result in serious personal injury.
•Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be caught
in moving parts.
•Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your
finger on the switch or plugging in tools that have
the switch on, invites accidents.
Remove adjusting keys or wrenches before
turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.
Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
enables better control of the tool in unexpected
situations.
•Use safety equipment. Always wear eye protec-
tion. Dust mask, nonskid safety shoes, hard hat,
or hearing protection must be used for appropriate
conditions.
Tool Use and Care
•Use clamps or another practical way to secure
and support the workpiece to a stable plat-
form. Holding the work by hand or against your
body is unstable and may lead to loss of control.
•Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.
•Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
•Disconnect the plug from power source before
making any adjustments, changing accesso-
ries, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool
accidentally.
•Store idle tools out of the reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
•Maintain tools with care. Keep cutting tools
sharp and clean. Propedy maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.
Check for misalignment or binding of moving
parts, breakage of parts, and any other condi-
tion that may affect the tool's operation, ff
damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained
tools.
Use only accessories that are recommended
by the manufacturer for your model. Accesso-
ries that may be suitable for one tool, may become
hazardous when used on another tool.
Service
•Tool service must be performed only by quali-
fied repair personnel. Service or maintenance
performed by unqualified personnel could result in
a risk of injury.
•When servicing a tool, use only identical
replacement parts. Follow instructions in the
Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance
Instructions may create a riskof electric shock or
injury.
Specific Safety Rules for Circular Saws
•DANGER! Keep hands away from cutting
area and blade. Keep your second hand on
the auxiliary handle or motor housing. If
both hands are holding the saw, they cannot
be cut by the blade.
•Keep your body positioned to either side
of the saw blade, but not in line with the
saw blade. Kickback could cause the saw to
jump backwards. (See "Causes and Operator
Prevention of Kickback.")
•Do not reach underneath the work. The
guard cannot protect you from the blade
below the work.
•Check lower guard for proper closing
before each use. Do not operate saw if
lower guard does not move freely and
close instantly. Never clamp or tie the
lower guard into the open position. If saw
is accidentally dropped, lower guard may be
bent. Raise the lower guard with the
retracting handle. Make sure it moves freely
and does not touch the blade or any other
part, in all angles and depths of cut.
•Check the operation and condition of the
lower guard spring. If the guard and the
spring are not operating properly, they
must be serviced before use. Lower guard
may operate sluggishly due to damaged
parts, gummy deposits, or a buildup of
debris.
•Lower guard should be retracted manually
only for special cuts, such as "Pocket
Cuts" and "Compound Cuts." Raise lower
guard by retracting handle. As soon as
blade enters the material, lower guard
must be released. For all other sawing, the
lower guard should operate automatically.

Specific Safety Rules for Circular Saws
(continued)
•Always observe that the lower guard is
covering the blade before placing saw
down on bench or floor. An unprotected,
coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be
aware of the time it takes for the blade to
stop after switch is released.
•NEVER hold piece being cut in your hands
or across your leg. It is important to support
the work properly to minimize body exposure,
blade binding, or loss of control.
•Hold tool by insulated gripping surface
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord, Contact with a "live" wire will
also make exposed metal parts of the tool
"live" and shock the operator.
•When ripping, always use a rip fence or
straight edge guide. This improves the
accuracy of the cut and reduces the chance
for blade binding.
•Always use blades with correct size and
shape (diamond vs. round) arbor holes.
Blades that do not match the mounting
hardware of the saw will run eccentrically,
causing loss of control.
•Never use damaged or incorrect blade
washers or bolts. The blade washers and
bolts were specially designed for your saw for
optimum performance and safety of
operation.
Causes and Operator Prevention of Kickback
• Kickback is a sudden reaction to a pinched,
bound, or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the
workpiece toward the operator.
• When the blade is pinched or bound tightly
by the kerf closing down, the blade stalls and
the motor reaction drives the unit rapidly back
toward the operator.
• If the blade becomes twisted or misaligned in
the cut, the teeth at the back edge of the
blade can dig into the top surface of the wood
causing the blade to climb out of the kerf and
jump back toward the operator.
• Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions
and can be avoided by taking proper
precautions, as given below:
•Maintain a firm grip with both hands on
the saw and position your body and arm
to allow you to resist KICKBACK forces.
KICKBACK forces can be controlled by the
operator, if proper precautions are taken.
•When blade is binding, or when
interrupting a cut for any reason, release
the trigger and hold the saw motionless in
the material until the blade comes to a
complete stop. Never attempt to remove
the saw from the work or pull the saw
backward while the blade is in motion, or
KICKBACK may occur. Investigate and take
corrective actions to eliminate the cause of
blade binding.
•When restarting a saw in the workpiece,
center the saw blade in the kerf and check
that saw teeth are not engaged into the
material. If saw blade is binding, it may walk
up or KICKBACK from the workpiece as the
saw is restarted.
•Support large panels to minimize the risk
of blade pinching and KICKBACK. Large
panels tend to sag under their own weight.
Supports must be placed under the panel on
both sides, near the line of cut and near the
edge of the panel.
•Do not use dull or damaged blade.
Unsharpened or improperly set blades
produce narrow kerf which causes excessive
friction, blade binding and KICKBACK.
•Blade depth and bevel adjusting locking
levers must be tight and secure before
making cut. If blade adjustment shifts while
cutting, it may cause binding and KICKBACK.
•Use extra caution when making a "Pocket
Cut" into existing walls or other blind
areas. The protruding blade may cut objects
that can cause KICKBACK.
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may con-
tact hidden wiring or its cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and
shock the operator.
Additional Rules For Safe Operation
• Know your power tool. Read operator's manual
carefully. Learn its applications and limitations,
as well as the specific potential hazards
related to this tool. Following this rule will reduce
the risk of electric shock, fire, or serious injury.
•Always wear safety glasses. Everyday eye-
glasses have only impact-resistant lenses;
they are NOT safety glasses. Following this rule
will reduce the risk of serious personal injury.
•Protect your lungs. Wear a face or dust mask if
the operation is dusty. Following this rule will
reduce the risk of serious personal injury.
•Protect your hearing. Wear hearing protection
during extended periods of operation. Following
this rule will reduce the risk of serious personal
injury.
•Inspect tool cords periodically and, if dam-
aged, have repaired at your nearest Factory
Service Center or other Authorized Service
Organization. Constantly stay aware of cord
location. Following this rule will reduce the risk of
electric shock or fire.
Check damaged parts. Before further use of
the tool, a guard or other part that is damaged
should be carefully checked to determine that
it will operate properly and perform its in-
tended function. Check for alignment of mov-
ing parts, binding of moving parts, breakage of
parts, mounting, and any other conditions that
may affect its operation. A guard or other part
that is damaged should be properly repaired or
replaced by an authorized service center.
Following this rule will reduce the risk of shock,
fire, or serious injury.
Do not abuse cord. Never carry the tool by the
cord or yank it to disconnect it from the recep-
tacle. Keep cord away from heat, on, and sharp
edges. Following this rule will reduce the risk of
electric shock or fire.
•Make sure your extension cord is in good
condition. When using an extension cord, be
sure to use one heavy enough to carry the
current your product will draw. A wire gage
size (A.W.G.) of at least 16 is recommended for
an extension cord 100 feet or less in length. A
cord exceeding 100 feet is not recommended.
If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.
An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
•Inspect for and remove all nails from lumber
before cutting. Following this rule will reduce the
risk of serious personal injury.
•Drugs, alcohol, medication. Do not operate tool
while under the influence of drugs, alcohol, or
any medication. Following this rule will reduce the
risk of electric shock, fire, or serious personal injury.
•Save these instructions. Refer to them fre-
quently and use them to instruct others who
may use this tool. If you loan someone this
tool, loan them these instructions also.
_ILWARNING: Some dust created by power
sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known
to cause cancer, birth defects or other reproduc-
tive harm. Some examples of these chemicals
are:
•lead from lead-based paints,
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed to
filter out microscopic particles.
_IL WARNING:
The operation of any circular saw can result in foreign objects being thrown into your eyes,
which can result in severe eye damage. Before beginning power tool operation, always wear
safety goggles or safety glasses with side shields and a full face shield when needed. We
recommend Wide Vision Safety Mask for use over eyeglasses or standard safety glasses
with side shields, available at Sears Retail Stores.

WARNING: Your saw should never be
connected to power supply when you are
assembling parts, making adjustments,
assembling or removing blades, cleaning, or
when not in use. Disconnecting your saw will
prevent accidental starting that could cause
serious personal injury.
,_i WARNING: A 7-1/4 in. blade is the maximum
blade capacity of your saw. Never use a blade that
is too thick to allow outer blade washer to engage
with the flat on the spindle. Larger blades will come
in contact with the blade guards, while thicker
blades will prevent blade screw from securing
blade on spindle. Either of these situations could
result in a serious accident.

SAW BLADES
The best of saw blades will not cut efficiently if they
are not kept clean, sharp, and properly set. Using a
dull blade will place a heavy load on your saw and
increase the danger of kickback. Keep extra blades
on hand, so that sharp blades are always available.
Gum and wood pitch hardened on blades will slow
your saw down. Use gum and pitch remover, hot
water, or kerosene to remove these accumulations.
Do not use gasoline.
BLADE GUARD SYSTEM
The lower blade guard attached to your circular
saw is there for your protection and safety. It
should never be altered for any reason. If it
becomes damaged or begins to return slow or
sluggish, do not operate your saw until the
damage has been repaired or replaced. Always
leave guard in operating position when using saw.
_i DANGER: When sawing through workpiece,
lower blade guard does not cover blade on the
underside of workpiece. Since blade is exposed
on underside of workpiece, keep hands and
fingers away from cutting area. Any part of your
body coming in contact with moving blade will
result in serious injury. See Figure 5.
LOWERBLADEGUARD
IS IN UP POSITION
KICKBACK
See Figure 6.
BLADESETTOO DEEP Fig. 6
The best guard against kickback is to avoid
dangerous practices.
Kickback occurs when the blade stalls rapidly and the
saw is driven back towards you. Blade stalling is
caused by any action which pinches the blade in the
wood.
_i DANGER: Release switch immediately if blade
binds or saw stalls. Kickback could cause you to
lose control of your saw. Loss of control can lead
to serious injury.
KICKBACK IS CAUSED BY:
•Incorrect blade depth setting. See Figure 6.
•Sawing into knots or nails in workpiece.
•Twisting blade while making a cut.
•Making a cut with a dull, gummed up, or improperly
set blade.
•Incorrectly supporting workpiece. See Figure 7.

correct operation before each use. If you drop
your saw, check the lower blade guard and
bumper for damage at all depth settings before
reuse. Note: The guard is operating correctly
when it moves freely and readily returns to the
closed position. If for any reason your lower
blade guard does not close freely, take it to the
nearest Sears Repair Center for service before
using.

TO LESSEN THE CHANCE OF KICKBACK:
• Always keep the correct blade depth setting - the
correct blade depth setting for all cuts should not
exceed 1/4 inch below the material to be cut. See
Figure 8.

• Inspect the workpiece for knots or nails before
beginning a cut. Never saw into a knot or nail.
• Make straight cuts. Always use a straight edge
guide when rip cutting. This helps prevent twisting
the blade in the cut.
• Always use clean, sharp and properly set blades.
Never make cuts with dull blades.
• To avoid pinching the blade, support the workpiece
properly before beginning a cut. The right and
wrong ways to support large pieces of work are
shown in Figures 7 and 9.
I
RIGHT Fig. 9
• When making acut use steady, even pressure.
Never force cuts.
• Do not cut warped or wet lumber.
• Always hold your saw firmly with both hands and
keep your body in a balanced position so as to
resist the forces of kickback should it occur.
When using your saw, always stay alert and
exercise control. Do not remove your saw from
workpiece while the blade is moving.
DEPTH OF CUT ADJUSTMENT
See Figure 10.
Always keep correct blade depth setting. The correct
blade depth setting for all cuts should not exceed 1/4
inch below the material to be cut. More blade depth
will increase the chance of kickback and cause the cut
to be rough. For more depth of cut accuracy, a scale
is located on the upper blade guard.
TO ADJUST BLADE DEPTH
• Unplug your saw.

STARTING A CUT
Know the right way to use your saw.
See Figure 11.
TO HELP MAINTAIN CONTROL:
• Always support your workpiece near the cut.
• Support your workpiece so the cut will be on your
right.
• Clamp your workpiece so it will not move during
the cut.
Place your workpiece with its good side down. Note:
The good side is the side on which appearance is
important.
Before beginning a cut, draw a guideline along the
desired line of cut. Then place front edge of base on
that part of your workpiece that is solidly supported.
See Figure 11.
Never place your saw on that part of the
workpiece that will fall off when the cut is made.
See Figure 13.
RIGHT Fig. 11
_L WARNING: To make sawing easier and safer,
always maintain proper control of your saw. Loss
of control of your saw could cause an accident
resulting in possible serious injury.
Never use your saw as shown in Figure 12.
WRONG Fig. 12
Never place your hand on the workpiece behind
your saw while making a cut.
WRONG Fig. 13
Keep the cord away from cutting area. Always place
the cord to prevent it from hanging up on the
workpiece while making a cut.
,_ DANGER: If the cord hangs up on the
workpiece during a cut, release the switch trigger
immediately. Unplug your saw and reposition the
cord to prevent it from hanging up again.
_L DANGER: Using your saw with a damaged cord
could result in serious injury or death. If the cord
has been damaged, have it replaced before
using your saw again.
12
Hold your saw firmly with both hands.
See Figure 14. _k CAUTION: When lifting your saw from the
workpiece, the blade is exposed on the
underside of your saw until the lower blade guard
closes. Make sure lower guard is closed before
setting your saw down on work surface.
TO CROSS CUT OR RIP CUT
When making a cross cut or rip cut, align your line of
cut with the outer blade guide notch on the saw base
as shown in Figure 15.
RIGHT Fig. 14
Squeeze the switch trigger to start your saw. Always
let the blade reach full speed, then guide your saw
into the workpiece.
,_ WARNING: The blade coming in contact with
the workpiece before it reaches full speed could
cause your saw to "kickback" towards you
resulting in serious injury.
When making acut use steady, even pressure.
Forcing causes rough cuts, could shorten the life of
your saw and could cause "kickback."
REMEMBER:
When sawing through work, the lower blade guard
does not cover the blade, exposing it on the

Since blade thicknesses vary, always make a trial cut
in scrap material along a guideline to determine how
much, if any, the guideline must be offset to produce
an accurate cut. Note: The distance from the line of
cut to the guideline is the amount you should offset
the guideline.

TO BEVEL CUT
The angle of cut of your saw may be adjusted to any
desired setting between zero and 51.5 °. Note: When
making cuts at 51.5 °blade should be set at full depth
of cut, with edge guide screw removed.
When making 45° bevel cuts, there is a notch in the
saw base to help you line up the blade with the line of
cut. See Figure 16.

GENERAL
Only the parts shown on parts list, page 21, are
intended to be repaired or replaced by the customer.
All parts represent an important part of the double
insulation system and should be serviced only at a
Sears Service Center.
Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from various
types of commercial solvents and may be damaged
by their use. Use clean cloths to remove dirt, carbon
dust, etc.
,_IWARNING: Do not at any time let brake fluids,
gasoline, petroleum-based products, penetrating
oils, etc. come in contact with plastic parts. They
contain chemicals that can damage, weaken or
destroy plastic.
It has been found that electric tools are subject to
accelerated wear and possible premature failure when
they are used on fiberglass boats, sports cars,
wallboard, spackling compounds, or plaster. The
chips and grindings from these materials are highly
abrasive to electric tool parts, such as bearings,
brushes, commutators, etc. Consequently, it is not
recommended that this tool be used for extended
work on any fiberglass material, wallboard, spackling
compounds, or plaster. During any use on these
materials, it is extremely important that the tool is
cleaned frequently by blowing with an air jet.
LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high-grade lubricant for the life of
the unit under normal operating conditions. Therefore,
no further lubrication is required.
_i WARNING: Always wear safety goggles or
safety glasses with side shields during power tool
operation or when blowing dust. If operation is
dusty, also wear a dust mask.also wear a dust
mask.
17
DOUBLE INSULATION
Double insulation is a concept in safety in electric
power tools, which eliminates the need for the usual
three-wire grounded power cord. All exposed metal
parts are isolated from the internal metal motor
components with protecting insulation. Double
insulated tools do not need to be grounded.
IMPORTANT
Servicing of a tool with double insulation requires
extreme care and knowledge of the system and
should be performed only by a qualified service
technician. For service, we suggest you return the tool
to your nearest Sears Service Center for repair.
Always use original factory replacement parts when
servicing.
EXTENSION CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating, use an extension cord that is heavy
enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 16 is recom-
mended for an extension cord 100 feet or less in
length. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
will be marked WA.
_k CAUTION: Keep extension cords away from the
cutting area and position the cord so that it will
not get caught on lumber, tools, etc., during
cutting operation.
_k WARNING: Check extension cords before each
use. If damaged replace immediately. Never use
tool with a damaged cord since touching the
damaged area could cause electrical shock
resulting in serious injury.
Extension cords suitable for use with your saw are
available at your nearest Sears Retail Store.
