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.

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,
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.
Avoid body contact with grounded surfaces,
such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if
your body is grounded.
Don't expose power tools to rain or wet conditions. 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.
Stay alert, watch what you are doing and use
common sense when operating a power tool.

Tool Use and Care
•
Use clamps or another practical way to secure
and support the workpiece to a stable platform. 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 accessories, 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.

Additional
Rules For Safe Operation
•
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.
•
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 eyeglasses 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.
•
Inspect for and remove all nails from lumber
before cutting. 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.
•
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.
•
Inspect tool cords periodically and, if damaged, 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.
•
Save these instructions. Refer to them frequently 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 reproductive harm. Some examples of these chemicals
are:
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 intended function. Check for alignment of moving 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.
• lead from lead-based
paints,
• crystalline silica from bricks and cement
and other masonry products, and
• arsenic and chromium from chemicallytreated 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.
Do not abuse cord. Never carry the tool by the
cord or yank it to disconnect it from the receptacle. Keep cord away from heat, on, and sharp
edges. Following this rule will reduce the risk of
electric shock or fire.
_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.

SAW BLADES
KICKBACK
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.
See Figure 6.
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
BLADESETTOO DEEP
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.
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.
_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.

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
•
When making a cut 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.
Figure 8.
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.

GENERAL
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
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.
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
,_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.
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
17
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.
DOUBLE
INSULATION
A wire gage size (A.W.G.) of at least 16 is recommended 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.
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.
_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.
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
Extension cords suitable for use with your saw are
available at your nearest Sears Retail Store.
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.
