GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. 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 ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify 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.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, 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.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon 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 inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. 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.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. 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.
4. 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 us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. 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.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. 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 main-
tained.
CALIFORNIA PROPOSITION 65 WARNING
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities may contain
chemicals, including lead, known to the State of Califor-
nia to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• 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 ex-
posure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

CIRCULAR SAW SAFETY WARNINGS
WARNING! Do not operate the power tool until you have read and understood the following instructions and
the warning labels.
CIRCULAR SAW SAFETY
1. TOOL PURPOSE. This circular saw is designed to cut
through softwood, tile, and aluminum only. Cutting other
materials could result in fire, injury, or damage to the
workpiece. Using the machine for any other purpose for
which it is not designed may result in serious injuries,
machine damage and voiding of the warranty.
2. Check the base plate for proper movement before
each use. Press the blade release button to make sure
the base plate can move freely and does not touch the
blade or any other parts. Do not operate the saw if the
base plate does not move or does not open and close
smoothly. Dropping the saw may cause the base plate to
not work properly.
3. PERSONAL SAFETY.
• Always wear ANSI Z87.1-approved glasses with side
shields, hearing protection and a dust mask.
• Do not wear loose clothing or jewelry, as they might get
drawn in by the tool. Tie back long hair.
• DO NOT wear gloves while operating this machine.
4. ELECTRIC CORDS. Keep cords away from heat, oil,
sharp edges, and moving parts of the tool. Have an elec-
trician replace or repair damaged or worn cords imme-
diately.
5. TOOL INSPECTION. Before operation, check the tool
for any damaged or missing parts. Do not use the tool
if any part is missing or damaged. Do not use the tool if
the power switch is faulty, the plug or cable is damaged,
or the tool produces sparks, smoke, or unpleasant odors
(you may smell brushes wearing down for a few minutes
as the tool breaks in during the first use, that is normal).
Make sure all adjustments are correct and all connec-
tions are tight.
6. SECURING THE WORKPIECE. Use clamps to secure
the workpiece whenever possible to prevent wobble,
damage to the workpiece, and personal injury. Never
hold a piece being cut in your hands or across your legs.
It is important to support the work properly to minimize
body exposure, blade binding, or loss of control.
7. STANDING POSITION. Keep your body positioned to
either side of the saw blade, but not in line with cutting
path. Kickback could cause the saw to jump backwards.
8. STARTING THE TOOL. Always start the saw before
the blade is in contact with the workpiece. Let the blade
reach full speed before using the tool. The reaction to the
torque as the motor accelerates to full speed may cause
the tool to kick back.
9. KEEP HANDS AWAY. Keep hands away from the cut-
ting area and the blade. Do not reach underneath the
workpiece. The blade guard cannot protect you from the
blade protruding from the underside of the workpiece.
Do not attempt to remove cut material when the blade
is moving.
10. DURING OPERATION. Do not apply excessive pres-
sure to the tool. Overstressing the tool may cause kick-
back and damage the tool and accessories. Use special
care when working corners, sharp edges etc.
6
These safety instructions can’t possibly warn of every scenario that may arise with this tool,
so always make sure to stay alert and use common sense during operation.
CIRCULAR SAW SAFETY WARNINGS
WARNING! Do not operate the power tool until you have read and understood the following instructions and
the warning labels.
CIRCULAR SAW SAFETY
11. TURNING OFF THE TOOL. The blade coasts after the
saw is turned off. Wait until the blade comes to a full
stop before reaching for loose materials or setting the
tool down.
12. REPLACING THE SAW BLADE. Check the blade for
chipped or broken teeth. Do not use dull or damaged
blades. Unshaped or improperly set blades produce nar-
row kerf, causing excessive friction, blade binding, and
kickback. Always use blades with correct size and arbor
holes. Blades that do not match the mounting hardware
of the saw will run eccentrically, causing a loss of con-
trol.
13. MAKING ADJUSTMENTS. Always turn off and un-
plug the saw before making adjustments or changing
attachments. Accidental start-ups may occur if the saw
is plugged in during an accessory change. Develop a pe-
riodic maintenance schedule for your tool. Always make
sure the power switch is in the OFF position and the ma-
chine is unplugged when doing any cleaning, assembly,
setup operations, or when not in use.
14. REPLACEMENTS. Should any component of your
saw be missing/damaged or fail in any way, shut off the
switch and remove the plug from power supply outlet.
Replace the missing, damaged, or failed parts using only
identical replacement parts before resuming operation.
REDUCING 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 work piece 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 towards the operator. Take the proper
precautions below to reduce the risk of kickback.
• Maintain a firm grip on the saw and position your body
and arm in a way that allows you to resist kickback forc-
es. Kickback forces can be controlled by the operator, if
proper precautions are taken.
• When a blade is binding (or when interrupting a cut for
any reason), release the trigger and hold the saw motion-
less 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.
• When restarting a saw in the workpiece, center the
blade in the kerf and check that the teeth are not en-
gaged into the material. If the saw blade is binding, it
may walk up or kickback from the work piece as the saw
is restarted. Investigate and take corrective actions to
eliminate the causes of blade binding.
• Support large workpieces to minimize the risk of blade
pinching and kickback. Large panels and boards tend to
sag under their own weight. Supports must be placed
under the panel or board on both sides, near the edge of
the panel or board.
• Do not use dull or damaged blades. Unshaped or im-
properly set blades produce narrow kerf, causing exces-
sive friction, blade binding, and kickback.
• Blade depth and bevel adjusting locking levers must
be tight and secure before making a cut. If the blade ad-
justment shifts while cutting, it will cause binding and
kickback.

IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. Polarized Plugs. To reduce the risk of electric shock, this equipment has 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 proper outlet. Do not modify the machine plug
or the extension cord in any way.
2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power
tool to reduce the risk of electric shock.
3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician
using original replacement parts.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
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. The table below shows
the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.
DOUBLE-INSULATED TOOL
The tool's electrical system is double-insulated where two systems of insulation are provided. This
eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need
to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are
isolated from the internal metal components with protecting insulation.
1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in
the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running
at a lower voltage will damage the motor.

ASSEMBLY & ADJUSTMENTS
SETTING THE DEPTH OF CUT
Before making a cut, it is important to set the correct cutting depth. The saw’s maximum cutting depth at 90° is
1-11/16 inch (43 mm) and at 45° it is 1-1/8" (28 mm). We recommend adjusting the cutting depth about 1/16 inch
(2 mm) deeper than the thickness of the material. To adjust the cutting depth, you can either refer to the depth scale,
or the edge of the workpiece.
CUTTING GUIDE INDICATOR
The cutting guide indicator (Fig. 5 - 1) can be found at the front of the
saw base. This guide helps to indicate where the cut will be occur-
ring. Before cutting, draw a guideline on the workpiece and follow the
guideline with the cutting guide to create more accurate cuts.

switch. Stand to the left side of the saw. (Do opposite if left-handed).
2. Set the front portion of the base plate onto the workpiece. Position the base plate with its right side resting on the
larger section of board that DOES NOT fall off when being cut. Align the cutting guide indicator (see page 12) with
the cutting guideline marked on the workpiece. Ensure that the blade is NOT in contact with the workpiece.
3. Pull the power switch back with your fingers to turn on the saw. Wait until the blade has reached full speed (ap-
proximately 3 seconds).
4. Make sure that the base plate is stable on the workpiece; this is very important especially during the start or fin-
ish of a cut. Push the blade release button with your thumb to lower the saw blade. Slowly push the blade into the
workpiece.
5. Gently push the saw forward along the cutting guideline while keeping the base plate flat against the workpiece
surface. Do not force the saw forward too quickly in order to try and hurry up the process. Let the tool work at its
own pace. Never pull the saw backwards while cutting.
WARNING! DO NOT start the saw while the blade is in contact with the workpiece, this may lead to kickback.
6. Let the saw blade run through the entire cut. Release the power switch and blade release button and allow the
blade to come to a full stop before lifting the saw off the work surface. Disconnect the saw from the power source.
WARNING! DO NOT raise the saw while it is running, this can expose you to the blade and lead to an injury.
Allow the blade to completely stop before lifting it from the work surface.
