READ ALL INSTRUCTIONS THOROUGHLY
GENERAL SAFETY RULES FOR ALL POWER TOOLS
WARNING!Read and understand all instructions. Failure to follow all in-
structions listed below may result in electric shock, fire and/or serious per-
sonal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep the work area clean and well lit. Cluttered benches and dark areas
invite accidents.
Do not operate power tools in an explosive environment, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite 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 three wire 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.
120V ~ 60Hz

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. The following table shows the correct size to
use, depending on cord length and nameplate amperage rating of the tool.
When in doubt, use the next heavier gauge. Always use UL and CSA listed
extension cords.

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, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
Before connecting the tool to a power source (receptacle, outlet, etc.), be
sure voltage supplied is the same as that specified on the nameplate of
the tool. A power source with voltage greater than that specified for the
tool can result in serious injury to the user – as well as damage to the tool.
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 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.
Do not alter or misuse tool. These tools are precision built. Any alteration or
modification not specified is misuse and may result in a dangerous condition.
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.
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.
SPECIFIC SAFETY RULES FOR CIRCULAR SAWS
DANGER! Keep hands away from cutting area and blade. Keep your sec-
ond hand on 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.
Do not reach underneath the work. The guard can not 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 and 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 backward, 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 also 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 cut and reduces the chance for blade binding.
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 bolt were specially designed for your 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 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.
Do not use dull or damaged blade. Unsharpened or improperly set blades
produce narrow kerf causing 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.

Do not use the circular saw near fumes or combustible liquids.
Never slow the blade down with your hands, or by applying pressure to
the side of the blade.
Never apply force! Move the circular saw forward gently and steadily.

Remember that one careless moment is enough to cause severe injury.
Before attempting to use any tool, be sure to become familiar with all of the
operating features and safety instructions.
WARNING! Do not allow familiarity with tools to cause carelessness. Re-
member that a fraction of a second of carelessness is sufficient to inflict seri-
ous injury.
WARNING! Always wear safety goggles or safety glasses with side shields
when operating power tools. Failure to do so could result in objects being
thrown into the operator’s eyes, resulting in possible serious injury.
APPLICATIONS
This saw can be used for the purpose listed below:
Cutting all types of wood and wood products
NOTE: The use of abrasive cut-off wheels is not recommended with this saw.
KICKBACK (Figs. 2-5)
Kickback occurs when the blade
stalls rapidly and the saw is driven
back toward the operator. Blade
stalling is caused by any action
that pinches the blade in the wood.
DANGER! Release the switch immediately if the blade binds or the saw
stalls. Kickback could cause loss of control of the saw. Loss of control can
lead to serious personal 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.
To reduce the chance of
kickback, follow these safety
practices:
Keep the blade at the correct
depth setting. The depth setting
should not extend more than
1/4” below the material that is
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 the blade from twisting.
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 maintain a balanced position in
order 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.
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
the saw blade from the saw, and use gum and pitch remover, hot water, or
kerosene to remove these accumulations. DO NOT USE GASOLINE.
CHANGING THE SAW BLADE (FIG. 6)
WARNING! To prevent personal injury, always disconnect the plug from the
power source before installing or removing the saw blade!
TO REMOVE THE SAW BLADE (Fig. 6)

the spindle.
BLADE GUARD SYSTEM (Fig.
8)
The lower blade guard on the
circular saw is there for the
operator’s protection and safety.
Do not alter it for any reason. If it
becomes damaged or begins to
run slowly or sluggishly, DO NOT operate the saw until the damaged part has
been repaired or replaced. ALWAYS leave the guard in its correct operating
position when using the saw.
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 hands and fingers
away from the cutting area. Serious injury will result if any part of the body
comes into contact with the moving blade.
CAUTION! To avoid possible serious injury, never use the saw when the
guard is not operating correctly. Check the guard for correct operation before
each use. The guard is operating correctly when it moves freely and instantly
returns to the closed position. If the saw is dropped, check the lower blade
guard and bumper for damage at all depth settings before using it.
If the lower blade guard does not snap closed at any time, 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. This
will usually restore the guard to its normal operating condition. If this does
not correct a slow or sluggishly closing lower guard, do not use the saw.
Take it to an authorized service technician for repair.
STARTING/ STOPPING THE SAW (Fig. 9)
To start the saw: Depress the switch trigger.
Always allow the blade reach full speed, and then guide the saw into the
workpiece.
WARNING! If the blade comes
into contact with the workpiece
before it reaches full speed, this
may cause the saw to “kick back”
toward the operator, resulting in
serious injury.
To stop the saw: Release the
switch trigger. After releasing 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.
ADJUSTMENTS
DEPTH-OF-CUT ADJUSTMENT (Fig. 10)
WARNING! ALWAYS maintain
the correct blade-depth setting.
The correct blade-depth setting
for all cuts should not exceed the
thickness of the material being cut
by more than 1/4” (6.5 mm). Great-
er blade depth will increase the
chance of kickback, and cause
the cut to be rough.
1. Unplug the saw.
2. Pull the depth-adjustment
lever upward to release it.
3. Determine the desired depth
of cut.
4. Hold the base flat against the
workpiece, and raise or lower
the saw until the indicator
mark on the saw aligns with
the desired depth on the scale.
5. Push down on depth-adjustment
lever to lock it into position.
AJUSTING THE CUTTING

to the scale on the 0°-50° bevel gauge).
3. Tighten the locking knob in order to secure the base plate.
OPERATION
(Fig.12 -14)
Refer to the figures in this section to learn the correct and incorrect ways of
handling the saw.
WARNING! To make sawing easier and safer, always maintain proper con-
trol 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 that the lower
blade guard is closed before set-
ting the saw down.
To make the best possible cut,
follow these helpful hints.
1. Hold the saw firmly with both
hands.
2. Avoid placing your hand on
the workpiece while making a
cut.
3. Support the workpiece so
that the cut is always to the
operator’s side.
4. Support the workpiece near
the cut.
5. Clamp the workpiece securely
so that the workpiece will not
move during the cut.
6. Always place the saw on the
portion of the workpiece that is
supported, and not on the “cut off” piece.
7. Place the workpiece with the “good” side down.
8. Draw a guideline along the desired cutting line before beginning the cut.
9. Keep the cord away from the
cutting area. Always place the
cord so that it is not hanging
on the workpiece while
making a cut.
DANGER! If the cord hangs on
the workpiece during a cut, re-
lease the switch trigger immedi-
ately. Unplug the saw and reposi-
tion the cord in order to prevent it
from hanging 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.
CROSS-CUTTING/RIP CUTTING (Fig. 15-17)
When making a cross-cut or rip cut, align the guideline with the full-length
kerf indicator on the base, as shown in Fig. 15. The distance from the saw
blade to the saw base is approximately 5” (12.7 cm) on the left side of the saw
and 1-3/8” (3.5 cm) on the right side.
Blade thicknesses vary, so you should always make a trial cut in scrap
material along a guideline to determine how much the guideline must be
offset from the guide in order to produce an accurate cut.
NOTE: The distance from the cutting line to the guideline is the amount by
which the guide should be offset.
RIP CUTTING
Use a guide when making long or
wide rip cuts.
Rip cutting using the edge guide:
1. Slide the edge guide into the
slot.
2. Align the guideline with the
full-length kerf indicator on
the base.
3. Adjust the guide so that the “0”
on the guide is aligned with the edge of the workpiece.
4. Secure the guide using the locking knob.
5. Secure the workpiece.

6. Position the face of the edge
guide firmly against the edge
of workpiece.
NOTE: The guiding edge of the
workpiece must be straight
in
order
for the cut to be straight.
Use caution to prevent the blade
from binding in the cut.
7. Saw along the workpiece,
keeping the guide firmly
against edge
in order
to
achieve a straight rip cut.
Rip cutting using a straight
edge:
1. Secure the workpiece.
2. Clamp a straight edge to the
workpiece using C-clamps.
NOTE: Position the C-clamps so
that they will not interfere with
the saw housing during the cut.
3. Saw along the straight edge
in
order
to achieve a straight rip
cut.
NOTE: Do not bind the blade in the cut.
BEVEL CUTTING
To make the best possible cut:
1. Align the cutting line with the inner blade-guide notch on the base when
making 45° bevel cuts.
2. Make a trial cut in scrap material along a guideline
in order
to determine
the amount to offset the guideline on the cutting material.
3. Adjust the angle of cut to any desired setting between 0° and 50°.
WARNING! Attempting a bevel cut without having the bevel adjustment
lever securely locked in place can result in serious injury.
to bevel cut (Fig. 18)
1. Hold the saw firmly with both hands, as shown
2. Rest the front edge of the base onto the workpiece.
3. Start the saw, and allow the
blade to reach full speed.
4. Guide the saw into the
workpiece, and make the cut.
5. Release the trigger, and
allow the blade to come to a
complete stop.
6. Lift the saw from the
workpiece.
POCKET CUTTING
WARNING! Always adjust the
bevel setting to
before making a pocket cut. Attempting a pocket cut at
any other setting can result in loss of control of the saw and possible serious
injury.
1.
Adjust the bevel setting to 0°.
2. Set the blade to the correct blade-depth setting.
3. Swing the lower blade guard up using the lower blade guard handle.
4. Hold the lower blade guard by the handle.
5. Rest the front of the base flat against the workpiece, with the rear of the
handle raised so that the blade does not touch the workpiece.
6. Start the saw, and allow the blade to reach full speed.
7. Guide the saw into the workpiece, and make the cut.
WARNING! Always cut in a forward direction when pocket cutting. Cutting
in the reverse direction could cause the saw to climb up on the workpiece and
kick back toward the operator.
WARNING! As blade starts cutting the material, release the lower guard
immediately. When the foot rests flat on the surface being cut, proceed cutting
in forward direction to end of cut.
8.
Release the trigger, and allow the blade to come to a complete stop.
9. Lift the saw from the workpiece.
10. Clear the corners out with a hand saw or sabre saw.
WARNING! Never tie the lower blade guard in a raised position. Leaving
the blade exposed could lead to serious injury.
