GENERAL SAFETY RULES
WARNING:
Read and understand all instructions. 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. Cluttered
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 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 threewire grounded power cord and grounded power supply
system.
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. Keep cord away
from heat, oil, sharp edges, or moving parts. Replace
damaged cords immediately. 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 influence of drugs, alcohol,
or medication. A moment 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 protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
TOOL USE AND CARE
Use clamps or other 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 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.
Store idle tools out of 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. Properly 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 condition that may
affect the tools operation. If 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. Accessories that may be
suitable for one tool, may become hazardous when used
on another tool.
Keep the tool and its handle 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 tool.
Following this rule will reduce the risk of loss of control
and deterioration of the enclosure plastic.

GENERAL SAFETY RULES
SERVICE
Tool service must be performed only by qualified
repair personnel. Service or maintenance performed by
unqualified personnel could result in a risk of injury.
SPECIFIC SAFETY RULES
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” later.)
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.
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 surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will 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.
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
risk of electric shock or injury.
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 the 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.

Page 5
SPECIFIC SAFETY RULES
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.
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.
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 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 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 12 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.
Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
If the power supply cord is damaged, it must be replaced
only by the manufacturer or by an authorized service
center to avoid risk.
LASER GUIDE WARNINGS:
Avoid direct eye exposure when using the laser guide.
The laser shall be used and maintained in accordance
with the manufacturer’s instructions.
Never aim the beam at a person or object other than the
workpiece.
Always ensure the laser beam is aimed at a sturdy
workpiece without reflective surfaces. Shiny reflective
sheet metal or similar shiny materials are not suitable for
laser use.
All repairs should be made by an authorized service
representative or the laser manufacturer.
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.

KICKBACK - BLADE SET TOO DEEP
INCORRECT
SUPPORT
Fig. 5
APPLICATIONS
You may use this product for the purposes listed below:
Cutting all types of wood products (lumber, plywood,
paneling)
Cross Cutting/Rip Cutting
Bevel Cutting
Pocket Cutting
KICKBACK
See Figures 5 - 8.
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:
Release switch immediately if blade binds or saw stalls.
Kickback could cause you to lose control of the saw. Loss
of control can lead to serious injury.
To guard against kickback, avoid dangerous practices such
as the following.
Setting blade depth incorrectly.
Sawing into knots or nails in workpiece.
Twisting the blade while making a cut.
Making a cut with a dull, gummed up, or improperly set
blade.
Supporting the workpiece incorrectly.
Forcing a cut.
Cutting warped or wet lumber.
Operating the tool incorrectly or misusing the tool.

Page 13
OPERATION
To lessen the chance of kickback, follow these safety
practices.
Keep the blade at the correct depth setting. The depth
setting should not exceed 1/4 in. below the material being
cut.
Inspect the workpiece for knots or nails before cutting.
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.
Use clean, sharp, and properly set blades. Never make
cuts with dull blades.
Support the workpiece properly before beginning a cut.
Use steady, even pressure when making a cut. Never
force a cut.
Do not cut warped or wet lumber.
Hold the saw firmly with both hands and keep your body
in a balanced position so as to resist the forces if kickback
should occur.
WARNING:
When using the saw, always stay alert and exercise
control. Do not remove the saw from the workpiece while
the blade is moving.
LOWER BLADE GUARD
IS IN UP POSITION
WHEN MAKING A CUT
Fig. 9
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.
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 down. Remove saw blade from the saw and use gum
and pitch remover, hot water, or kerosene to remove these
accumulations. DO NOT USE GASOLINE.
BLADE GUARD SYSTEM
See Figure 9.
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.
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.

OPERATION
ADJUSTING BLADE DEPTH
See Figure 10.
Always keep correct blade depth setting. The correct blade
depth setting for all cuts should not exceed 1/4 in. below
the material being 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
Unplug the saw.
.
WARNING:
Failure to unplug the tool could result in accidental
starting causing serious injury.
Loosen depth adjustment knob.
Determine the desired depth of cut.
Locate depth of cut scale on back of upper blade
guard.
Hold base flat against the workpiece and raise or lower
saw until the indicator mark on bracket aligns with notch

OPERATING THE SAW
See Figures 12 - 14.
It is important to understand the correct method for operating
the saw. Refer to the figures in this section to learn the correct
and incorrect ways for handling the saw.
WARNING:
To make sawing easier and safer, always maintain proper
control of the saw. Loss of control could cause an
accident resulting in possible serious injury.
DANGER:
When lifting the saw from the workpiece, the blade is
exposed on the underside of the saw until the lower blade
guard closes. Make sure the lower blade guard is closed
before setting the saw down.
To make the best possible cut, follow these helpful hints.
Hold the saw firmly with both hands.
Avoid placing your hand on the workpiece while making
a cut.
Support the workpiece so that the cut is always on your
right.
Support the workpiece near the cut.
Clamp the workpiece securely so that the workpiece will
not move during the cut.
Avoid placing the saw on the part of the workpiece that
will fall off when the cut is made.
Place the workpiece with the “good” side down.
Draw a guideline along the desired line of cut before
beginning your cut.
Keep the cord away from the cutting area. Always place
the cord to prevent it from hanging up on the workpiece
while making a cut.
Fig. 12
Fig. 13
DANGER:
If the cord hangs up on the workpiece during a cut,
release the switch trigger immediately. Unplug the saw
and reposition the cord to prevent it from hanging up
again.
DANGER:
Using a saw with a damaged cord could result in serious
injury or death. If the cord has been damaged, have it
replaced before using the saw again.

OPERATION
CROSS CUTTING/RIP CUTTING
See Figure 15.
When making a cross cut or rip cut, align the line of cut
with the outer blade guide notch on the base as shown in
the figure.
Since blade thicknesses vary, always make a trial cut in scrap
material along a guideline to determine how much, if any, you
must offset the guideline to produce an accurate cut.
NOTE: The distance from the line of cut to the guideline is
the amount you should offset the guide.
TO RIP CUT
See Figures 16 - 17.
Use a guide when making long or wide rip cuts with the
saw.
To rip cut using optional edge guide:
Slide edge guide into the slot.
Align the guideline with the blade guide notch on the
base.
Adjust the guide so that the “0” on the guide is aligned
with the edge of the workpiece.
Secure the guide with the lock knob provided with the
saw.
Secure the workpiece.
Position the face of the edge guide firmly against the edge
of workpiece.
NOTE: The guiding edge of the workpiece must be
straight for your cut to be straight. Use caution to prevent
the blade from binding in the cut.
Saw along workpiece keeping guide firmly against edge
to achieve a straight rip cut.
To rip cut using a straight edge:
Secure the workpiece.
Clamp a straight edge to the workpiece using
C-clamps.
NOTE: Position C-clamps so they will not interfere with
the saw housing during the cut.
Saw along the straight edge to achieve a straight rip
cut.
NOTE: Do not bind the blade in the cut.

GENERAL MAINTENANCE
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, dust, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleumbased products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
Electric tools used on fiberglass material, wallboard, spackling
compounds, or plaster are subject to accelerated wear and
possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended
using this tool for extended work on these types of materials.
However, if you do work with any of these materials, it is
extremely important to clean the tool using compressed
air.
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.
CAUTION:
Use of controls or adjustments or performance other than
those specified herein may result in hazardous radiation
exposure.
