GENERAL SAFETy RULES
Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to
a rotating part of the power tool may result in personal
injury.
WARNING!
Read all instructions. Failure to follow all instructions
listed below may result in electric shock, fire and/or
serious injury. The term “power tool” in all of the warn-
ings listed below refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
Do not overreach. keep proper footing and balance
at all times. This enables better control of the power tool
in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry.
keep your hair, clothing and gloves away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of these devices can
reduce dust-related hazards.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
SAVE THESE INSTRUCTIONS
WORk AREA SAFETy
keep work area clean and well lit. Cluttered or dark
areas invite accidents.
Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
power tool in unexpected situations.
keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETy
POWER TOOL USE AND CARE
Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the job
better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
condition that may affect the power tool’s operation.
If damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
Do not abuse the cord. Never use the cord for carrying,
pulling or unplugging the power tool. keep cord away
from heat, oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces 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 a power tool while you are tired or under the
influence of drugs, alcohol or medication. A moment
of inattention while operating power tools may result in
serious personal injury.
Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety
shoes, hard hat, or hearing protection used for appropri-
ate conditions will reduce personal injuries.
keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
Use the power tool, accessories and tool bits etc., in
accordance with these instructions and in the manner
intended for the particular type of power tool, taking
into account the working conditions and the work to
be performed. Use of the power tool for operations dif-
ferent from those intended could result in a hazardous
situation.
Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools
with your finger on the switch or plugging in power tools
that have the switch on invites accidents.

GENERAL SAFETy RULES
When servicing a power tool, use only identical re-
SERVICE
placement parts. Follow instructions in the Mainte-
nance section of this manual. Use of unauthorized parts
or failure to follow Maintenance instructions may create
a risk of shock or injury.
Have your power tool serviced by a qualified repair
person using only identical replacement parts. This will
ensure that the safety of the power tool is maintained.
WARNING!
To reduce the risk of injury, user must read instruction
manual.
SPECIFIC SAFETy RULES
DANGER! keep hands away from cutting area and the
blade. keep your second hand on auxiliary handle or
motor housing. If both hands are holding the saw, they
cannot be cut by the blade.
Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform.
It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
Hold power 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 also make exposed metal parts of the
power tool “live” and shock the operator.
Kickback is the result of saw 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 arms to resist kickback forces. Position
your body to either side of the blade, but not in line
with the blade. Kickback could cause the saw to jump
backwards, but 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
completestop.Neverattempttoremovethesawfrom
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.
When ripping, always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces
the chance of blade binding.
Always use blades with correct size and shape
(diamond versus round) of 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
bolt. Thebladewashersandboltwerespeciallydesigned
for your saw for optimum performance and safety of
operation.
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 blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
Bladedepthandbeveladjustinglockingleversmustbe
tightandsecurebeforemakingcut.Ifbladeadjustment
shifts while cutting, it may cause binding and kickback.
Use extra caution when making a “Plunge Cut” into

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.

SPECIFIC SAFETy RULES
not touch the blade or any other part, in all angles and
depths of cut.
Inspect tool cords periodically and, if damaged, have
repaired at your nearest authorized service center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
Check the operation 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 “Plunge Cuts” and “Compound
Cuts.” Raise lower guard by retracting handle. As
soon as blade enters the material, the lower guard
must be released. For all other sawing, the lower guard
should operate automatically.
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.
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.
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.
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 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. An
undersized cord will cause a drop in line voltage resulting
in loss of power and overheating.
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.
Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
Ifthepowersupplycordisdamaged,itmustbereplaced
only by the manufacturer or by an authorized service
center to avoid risk.
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.
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.
Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.

ELECTRICAL
DOUBLE INSULATION
EXTENSION CORDS
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.
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the product will draw. An
undersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
WARNING:
When working outdoors with a product , use an extension
cord that is designed for outside use. This type of cord is
designated with “WA” or “W” on the cord’s jacket.
The double insulated system is intended to protect
the user from shock resulting from a break in the tool’s
internal insulation. Observe all normal safety precautions
to avoid electrical shock.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
NOTE:Servicingofaproductwithdoubleinsulationrequires
extreme care and knowledge of the system and should
be performed only by a qualified service technician. For
service, we suggest you return the product to your near-
est authorized service center for repair. Always use original
factory replacement parts when servicing.

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 the 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 the saw

BLADE GUARD SySTEM
See Figure 11.
BLaDe exPOSeD ON
uNDerSiDe Of wOrKPieCe
The lower blade guard attached to the circular saw is there
for your protection and safety. Do not alter it for any reason.
If it becomes damaged, do not operate the saw until you
have the guard repaired or replaced. Always leave guard in
operating position when using the saw.
Fig. 11
CAUTION:
Never use saw when guard is not operating correctly.
Check the guard for correct operation before each use.
The guard is operating correctly when it moves freely and
readily returns to the closed position. If you drop the saw,
check the lower blade guard and bumper for damage at
all depth settings before reuse.
DANGER:
When sawing through work, lower blade guard does not
cover blade on the underside of work. Since blade is
exposed on underside of work, keep hands and fingers
away from cutting area. Any part of your body coming in
contact with moving blade will result in serious injury.
WARNING:
Never tie the lower blade guard in a raised position. Leav-
ing the blade exposed could lead to serious injury.

OPERATION
If at any time the lower blade guard does not snap closed,
unplug the saw from the power supply. Exercise the lower
guard by moving it rapidly back and forth from the full open
position to the closed position several times. Normally this
will restore the guard to its normal operating condition. If
it does not correct a slow or sluggish closing lower guard,
do not use the saw. Take it to an authorized factory service
center for repair.

STARTING/STOPPING THE SAW
See Figure 12.
To start the saw: Depress the switch trigger.
Always let the blade reach full speed, then guide the saw
into the workpiece.
Fig. 1ꢀ
WARNING:
iNDex POiNT
The blade coming in contact with the workpiece before
it reaches full speed could cause the saw to “kickback”
towards you resulting in serious injury.
To stop the saw: Release the switch trigger.
After you release the switch trigger, allow the blade to come
to a complete stop. Do not remove the saw from the
workpiece while the blade is moving.
ADJUSTING BLADE DEPTH
See Figure 13.
Alwayskeepcorrectbladedepthsetting.Lessthanafulltooth
of the blade teeth should be visible below the workpiece.
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.
