NOTE:
DOUBLEINSULATION
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 internal metal motor
components with protecting insulation. Double
insulated tools do not need to be grounded.

READ ALL INSTRUCTIONS
KNOW YOUR POWER TOOL. Read owner's
manual carefully. Learn its applications and
limitations as well as the specific potential
hazards related to this tool.
GUARD AGAINST ELECTRICAL SHOCK BY
PREVENTING BODY CONTACT WITH
GROUNDED SURFACES, For example; pipes,
radiators, ranges, refrigerator enclosures.
KEEP GUARDS IN PLACE AND IN WORKING
ORDER. Never wedge or tie lower blade guard
open. Check operation of lower blade guard
before each use. Do not use if lower blade guard
does not close briskly over saw blade.
WARNING: If saw is dropped, lower blade
A
guard or bumper may be bent, restricting full
return.
If lower blade guard or bumper become bent or
damaged, replace them before reuse.
KEEP WORK AREA CLEAN. Cluttered areas
and benches invite accidents.
AVOID DANGEROUS ENVIRONMENT, Don't
use power tools in damp or wet locations or
expose to rain. Keep work area well lit.
KEEP CHILDREN AND VISITORS AWAY. All
visitors should wear safety glasses and be kept
safe distance from work area. Do not let visitor_
contact tool or extension cord.
STORE IDLE TOOLS. When not in use, tools
should be stored in a dry and high or locked-up
place - out of the reach of children.
DON'T FORCE TOOL. It will do the job better
and safer at the rate for which it was designed.

RULES FOR SAFE OPERATION (Continued)
USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool.
Don't use tool for purpose not intended - for
example - A circular saw should never be used
for cutting tree limbs or logs.
WEAR PROPER APPAREL. Do not wear loose
clothing or jewelry that can get caught in tool's
moving parts and cause personal injury. Rubber
gloves and nonskid footwear are recommended
when working outdoors. Wear protective hair
covering to contain long hair and keep it from
being drawn into nearby air vents.
ALWAYS WEAR SAFETY GLASSES. Everyday
eyeglasses have only impact-resistant lenses;
they are not safety glasses.
PROTECT YQUR LUNGS. Wear a face or dust
mask if the cutting operation is dusty.
PROTECT YOUR HEARING. Wear hearing
protection during extended periods of operation.
DON'T ABUS_CORD. Never carry tool by cord
or yank it to disconnect from receptacle. Keep
cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold
work. It's safer than using your hand and itfrees
both hands to operate tool.
DON'T OVERREACH. Keep proper footing and
balance at all times. Do not use on a ladder or
unstable support. Secure tools when working at
elevated positions.
MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for best and safest performance.
Follow instructions for lubricating and changing
accessories.
DISCONNECT TOOLS. When not in use, before
servicing, or when changing attachments,
blades, bits, cutters, etc., all tools should be
disconnected from power supply.
REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from
tool before turning it on.
AVOID ACCIDENTAL STARTING. Don't carry
plugged-in tool with finger on switch. Be sure
switch is off when plugging in.
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. An undersized
cord will cause a drop in line voltage resulting in
loss of power and overheating. A wire gage size
(A.W.G.) of at least 14 is recommended for an
extension cord 50 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.
OUTDOOR USE EXTENSION CORDS. When
tool is used outdoors, use only extension cords
suitable for use outdoors. Outdoor approved
cords are marked with the suffix W-A, for ex-
ample - SJTW-A or SJOW-A.
• KEEP BLADES CLEAN AND SHARP. Sharp
blades minimize stalling and kickback.
KEEP HANDS AWAY FROM cu'n'ING AREA.
Keep hands away from blades. Do not reach
underneath work while blade is rotating. Do not
attempt to remove cut material when blade is
moving.
_, WARNING: Blades coast after turn off.
• NEVER USE IN AN EXPLOSIVE ATMO-
SPHERE. Normal sparking of the motor could
ignite fumes.
INSPECT TOOL CORDS PERIODICALLY and if
damaged, have repaired by authorized service
facility. Stay constantly aware of cord location
and keep it well away from the rotating blade.
• INSPECT EXTENSION CORDS PERIODI-
CALLY and replace if damaged.
KEEP HANDLES DRY, CLEAN, AND FREE
FROM OIL AND GREASE. Always use a clean
cloth when cleaning. Never use brake fluids,
gasoline, petroleum-based products, or any
strong solvents to clean your too!.
STAY ALERT AND EXERCISE CONTROL.
Watch what you are doing and use common
sense. Do not operate {ool when you are tired.
Do not rush.
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 pads,
binding of moving pads, 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 re-
placed by an authorized service center.
• DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches
replaced by an authorized service center.

RULES FOR SAFE OPERATION (Contlnued)
• USE RIP FENCE. Always use a fence or
straight edge guide when ripping.
SUPPORT LARGE PANELS. To minimize the
risk of blade pinching and kickback, always
support large panels as shown in figure 9, page
10. When cutting operation requires the resting
of the saw on the workpiece, the saw should be
rested on the larger portion and the smaller piece
cut off.
• LOWER BLADE GUARD.
,_ WARNING: If lower blade guard must be raised
to make a cut, always raise itwith the retracting
handle to avoid serious injury. See Figure 21,
Page 15.
• GUARD AGAINST KICKBACK. Kickback occurs
when the saw stalls rapidly and isdriven back
towards the operator. Release switch immedi-
ately if blade binds or saw stalls. Don't remove
saw from work during a cut while the blade is
moving, See Pages.9 and 10.
• BEFORE MAKING A CUT, BE SURE THE
DEPTH AND BEVEL ADJUSTMENTS ARE
TIGHT.
USE ONLY CORRECT BLADES. Do not use
blades with incorrect size holes. Never use blade
washers or bolts that are defective or incorrect.
The maximum blade capacity of your saw is
7-1/4 inches.
AVOID CUTTING NAILS. Inspect for and
remove all nails from lumber before cutting.
NEVER touch the blade or other moving parts
during use.
NEVER start a tool when its rotating component
is in contact with the workpiece.
NEVER lay a tool down before its moving parts
have come to a complete stop.
DO NOT operate this tool while under the
influence of drugs, alcohol, or any medication.
POLARIZED" PLUGS. To reduce the riskof
electric shock, this tool has a polarized plug (one
blade iswider than the other). This plug will fit in
a polarized outlet only one way. Ifthe plug does
not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to
install the proper outlet. Do not change the plug
in any way.

activities contains chemicals known to cause cancer, birth defects or other reproductive 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.
