SAFETY
1. 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.
2. Double insulation [] eliminates the need for the three-wire grounded power
cord and grounded power supply system. Applicable only to Class II
(double insulated) tools.
3. Before plugging in the tool, RE SURE that the outlet voltage supplied is
within the voltage marked on the tool's data plate. DO NOT use "AC only"
rated tools with a DC power supply.
4. ALWAYS 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.
5. If operating
the power tool in damp locations
is unavoidable,
ALWAYS
use a Ground Fault Circuit

SAFETY
1. ALWAYS 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 influence
of drugs, alcohol,
or medication.
A moment of inattention
while operating power tools may result in serious personal injury.
2. ALWAYS dress properly.
DO NOT wear loose clothing
or jewelry. Pull
back long hair. Keep your hair, clothing,
and gloves away from moving
parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
3. ALWAYS 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 in the "On" position invites accidents.
4. ALWAYS 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.
5. DO NOT overreach.
ALWAYS
keep proper footing
and balance at all
times. Proper footing and balance enables better control of the tool in
unexpected
situations.
6. ALWAYS use safety equipment.
Always wear eye protection.
Dust mask,
non-skid safety shoes, hardhat, or hearing protection must be used for
appropriate
conditions.

TOOL USE AND CARE SAFETY
1. ALWAYS use clamps
or other practical ways 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.
2. DO NOT force tool. Use the correct tool and blade for your application.
The correct tool and blade will do the job better and safer at the rate for which
it is designed.
3. 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.
4. ALWAYS disconnect
the plug from the power source before making any
adjustments,
changing
accessories,or
storing
the tool. Such preventive
safety measures reduce the risk of starting the tool accidentally.
5. ALWAYS store idle tools out of reach of children and other untrained
persons. Tools are dangerous
in the hands of untrained users.
6. ALWAYS maintain
tools with care. Keep cutting
tools sharp and clean.
Properly maintained
tools with sharp cutting edges are less likely to bind
and are easier to control.
7. ALWAYS check for misalignment
of parts, and any other condition

SAFETY
RULES
FOR CIRCULAR
SAWS
Z_ 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.
1. ALWAYS 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 Kickback...What
Causes It and Ways to Prevent It on pages 7-8).
2. DO NOT reach underneath
the work. The guard cannot protect you from
the blade beneath the work.
3. ALWAYS check lower guard for proper closing
BEFORE each use.
DO NOT operate
the saw if the lower guard does not move freely and
close instantly.
Never clamp or tie the lower guard in the open position.
If the saw is accidentally
dropped, the lower guard may be bent. Raise the
lower guard with the retracting handle. Make sure that it moves freely and
does not touch the blade or any other part in all angles and depths of cut.
4. ALWAYS 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. The lower guard may operate sluggishly, due to
damaged
parts, gummy deposits, or a buildup of debris.
5.The lower guard should
be retracted
manually
ONLY for making special
cuts, such as pocket or compound
cuts. ALWAYS raise the lower guard
by retracting
the handle. As soon as the blade enters the material, the
lower guard MUST be released.
For all other sawing, the lower guard
should operate automatically.
6. ALWAYS make sure that the lower guard is covering
the blade BEFORE
placing
the saw down on a work bench or floor. An unprotected
moving
blade will cause the saw to walk backwards,
cutting whatever is in its path.
Make note of the time it takes for the blade to stop spinning after the
switch is released.
7. NEVER hold the piece being cut in your hands or across your legs.
It is important to support the work properly in order to minimize body
exposure,
blade binding, or loss of control.
8. ALWAYS hold tool by insulated
gripping
surfaces
when performing
an operation
where the cutting
tool may contact
hidden wiring or its
own cord. Contact with a 'live" wire will make the exposed metal parts of
the tool "live" and shock the operator.
9.When
ripping,
ALWAYS use a rip fence or straight
edge guide. This
improves the accuracy of the cut and reduces the chance of the blade binding.
10. ALWAYS use blades that have the correct
size and shape (diamond
vs. round) arbor holes. Blades that do not match the mounting hardware
of the saw will run erratically
and will cause loss of control.

I
I
SAFETY RULES FOR CIRCULAR SAWS cont.
11. ALWAYS BE SURE that all adjusting screws and the blade holder are
fastened tightly BEFORE making a cut. Loose adjusting screws and holders
can cause the tool or blade to slip and loss of control may result.
12. When removing the blade from the tool, ALWAYS avoid contact with skin
and ALWAYS wear protective gloves when grasping the blade or accessory.
Accessories
may be hot after prolonged use.
KICKBACK...WHAT
The Causes
CAUSES
IT AND WAYS TO PREVENT
IT
of Kickback
1. Kickback is a sudden reaction to a pinched, bound or misaligned saw blade,
which causes the uncontrolled
sawto lift up and out of the workpiece and
towards the operator.
2. When the blade is pinched or bound tightly by the kerr closing down, the
blade stalls and the motor reaction drives the unit rapidly back towards
the operator.
3. 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. This causes the
blade to climb out of the kerf and jump back towards the operator.
4. Kickback is a result of toot misuse and/or incorrect operating procedures or
conditions. It can be avoided by taking the proper precautions, as listed betow.
Ways to Prevent Kickback
1. ALWAYS maintain a firm grip with both hands on the saw and position
your body and arms to allow you to resist KICKBACK
forces.
KICKBACK
forces can be controlled by the operator, if the proper
precautions
are taken.
2. If the blade is binding, or when you are interrupting
a cut for any
reason, ALWAYS 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. ALWAYS check and be
ready to take corrective action to eliminate the cause of blade binding.
3. When restarting
the saw in
in the kerf and check to be
into the material. If the saw
from the workpiece when the
the workpiece,
ALWAYS center the blade
sure that the saw teeth are not engaged
blade is binding, it may walk up or KICKBACK
saw is restarted.
4. ALWAYS 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.
7
Ways to Prevent Kickback cont.
5. DO NOT use a dull or damaged blade. Unsharpened or improperly set
blades produce narrow kerr which causes excessive friction, blade
binding and KICKBACK.
6. ALWAYS be sure that the blade depth and adjusting locking levers are
tight and secure BEFORE making a cut. If blade adjustment shifts while
cutting, it may cause binding and KICKBACK.
7. ALWAYS 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.
8. ALWAYS have saw blade at full speed before contacting workpiece.
ALWAYS hold tool by insulated gripping surfaces when performing an
operation
where the cutting tool may contact hidden wiring or its own
cord. Contact with a 'live" wire will make the exposed metal parts of the tool
"live" and shock the operator.

SAW BLADES
All saw blades need to be kept clean, sharp and properly set in
order to cut efficiently. Using a dull blade places a heavy load on the saw
and increases the danger of kickback. Keep extra blades on hand, so sharp
blades are always available. Gum and wood pitch hardened on the blade
slows the saw down. Use gum and pitch remover, hot water or kerosene to
remove them. 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 slowly or sluggishly, DO NOT
operate your saw until the damage has been repaired or replaced. ALWAYS
leave the guard in its correct operating position when using the saw.
Z_ DANGER:
When sawing through a workpiece,
the lower blade guard
does not cover the blade on the underside of the workpiece. Since the blade
is exposed on the underside of the workpiece, ALWAYS keep your hands and
fingers away from the cutting area. Any part of your body coming in contact
with the moving blade will result in serious injury (see Fig. 3).
CAUTION: NEVER
use the saw when the guard is not operating
properly. The guard should be checked for correct operation before each use.
If you drop your saw, check the lower blade guard and bumper for damage at
all depth setting before using. NOTE: The guard is operating properly when it
moves freely and then readily returns to the closed position. If, for any reason.
your lower blade guard does not close freely, take it to your nearest Sears
Repair Center for service before using it.

KICKBACK
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.
IMPORTANT: The best guard against kickback is to avoid
dangerous practices,
DANGER:
ALWAYS release trigger switch immediate!y
if the blade
binds or the saw stalls. Kickback could cause you to lose control of the saw.
Loss of control can lead to serious injury.

Right
7. DO NOT cut wet or warped lumber.
8. ALWAYS hold the saw firmly with both
hands and keep your body in a balanced
position. This will help you resist the forces of kickback, should it occur.
IMPORTANT:
When using your saw, ALWAYS stay alert and exercise control.
DO NOT remove your saw from the workpiece,
while the blade is moving.
DEPTH-OF-CUT
ADJUSTMENT
ALWAYS use the correct blade depth setting. The correct blade depth setting
for all cuts should not be more than 1/4-inch below the material being cut.
Allowing more depth will increase the chance of kickback and cause the cut to
be rough. Your saw is equipped with a depth-of-cut
scale on the upper blade
guard that will provide increased depth-of-cut
accuracy (See Fig. 8).

2. ALWAYS support the workpiece so
the cut will be on your right.
3. ALWAYS clamp the workpiece
so it will not move during the cut.
Place the workpiece with the good
side down.
NOTE: The good side is the side
where appearance
is important.
.
Before starting a cut, draw a guiee ine
along the desired line of cut. Then place
the front edge of the saw base on that
part of the workpiece, that is solidly
supported (See Fig. 9).
4.NEVER place the saw on the part of
the workpiece that will fall off when
the cut is made (see Fig. 10).

MAKING
CROSS
CUTS OR RIP CUTS
1. When making cross or rip cuts, align
your line of cut with the outer blade
guide notch on the base of the saw
(See Fig. 12).
2. Since blade thicknesses
vary, ALWAYS
make a trial cut in scrap material along
the guideline to determine how much,
if any the guideline must be offset to
get an accurate cut.
MAKING
BEVEL
CUTS
1. Your saw can be adjusted to cut at any
angle between 0° and 45 °. 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 Fig. 13).
2. Align your line of cut with the inner
blade guide notch on the base of the
saw when making 45 ° bevel cuts.
3. Since blade thicknesse can vary and
different angles require different settings,
ALWAYS make a trial cut in scrap
materials along a guideline to determine
how much you should offset the guideline
on the board to be cut.
4. When making a bevel cut ALWAYS hold
your saw firmly with both hands
(See Fig. 14).
5. Rest the front edge of the base on the
workpiece.
Then squeeze the trigger
switch to start the saw. ALWAYS let the

MAKING RIP CUTS
ALWAYS use a guide when making long or wide rip cuts with your saw. You can
use either a straight edge or use the Optional Rip/Edge Guide with a 5-inch scale
(sold separately at your local Sears store or Craftsman outlet).
Using a Straight Edge
You can make an efficient rip guide
by clamping a straight edge to your
workpiece. (See Fig.17)
1. Secure
the workpiece.
2. Use C-clamps to firmly attach straight
edge to the workpiece.
3. Carefully guide the saw along the
straight edge for a straight rip cut.
4. DO NOT bind the blade in the cut.

GENERAL
WARNING: To avoid accidents, ALWAYS disconnect the tool from
the power source BEFORE cleaning or performing any maintenance.
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.
/!X WARNING: DO NOT at any time let brake fluids, gasoline,
petroleum-based
products, penetrating oils, etc. to come in contact
with plastic parts. They contain chemicals that can damage, weaken
or destroy plastic.
It is a known fact that e_ectric tools are subject to accelerated wear and
possible premature failure when they are used to work on fiber glass
boats and sports cars, wallboard, spackling compounds or plaster. The
chips and grindings from these materials are highly abrasive to electrical
tool parts, such as bearings, brushes, commutators,
etc. Consequently,
it is not recommended
that this tool be used for extended work on any
fiber glass material, wallboard, spackling compound, 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 too] are lubricated with a sufficient amount of
high-grade lubricant for the life of the tool under normal operating conditions.
Therefore, no further lubrication is required.
I
or side shields when using this tool or blowing dust. If operation is dusty,
ALWAYS wear safety goggles or safety glasses with
also WARNING:
wear a dust mask.
DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which
eliminates the need for the standard 3-wire grounded power cord. All
exposed metal parts are isolated from the internal motor components with
protecting insulation. Double insulated tools do not need to be grounded.
IMPORTANT
The 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 recommend
that you return the tool to your nearest
Sears Service Center for repair. ALWAYS use identical replacement
parts when servicing.
23
EXTENSION
CORDS
The use of any extension cord will cause some loss of power.To keep the loss
at a minimum and to prevent overheating, use an extension cord that is heavy
enough to carry the current that the tool will draw.
A wire gauge (AWG) of at least 16 is recommended
for an extension cord
• 100 feet or less in length. When working outdoors ALWAYS use an extension
cord that is suitable for outdoor use.The cord's jacket will be marked WA.
CAUTION:
Keep extension cords away from the cutting area,
and position the cord so it will not get caught on lumber, tools, etc.
during the cutting operation.
WARNING: Check extension cords before each use. If damaged,
replace it immediately. NEVER use a tool with a damaged cord because
touching the damaged area could cause electrical shock, resulting in
serious injury.
