SAVE ALL WARNINGS AND
INSTRUCTIONS FOR FUTURE
REFERENCE
The term “power tool” in the warnings
refers to your mains-operated (corded)
power tool or battery-operated (cordless)
power tool.
1) WORK AREA SAFETY
a) Keep work area clean and well
lit. Cluttered or dark areas invite
accidents.
b) Do not operate power tools in
explosive atmospheres, such
as in the presence of ammable
liquids, gases or dust. Power tools
create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose
control.
2) Electrical safety
a) 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. Unmodied plugs and
matching outlets will reduce risk of
WARNING
!
electric shock.
b) 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.
c) Do not expose power tools to rain
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
d) 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.
e) When operating a power tool
outdoors, use an extension cord
suitable for outdoor use. Use
of a cord suitable for outdoor use
reduces the risk of electric shock.
f) If operating a power tool in damp
location is unavoidable, use a
ground fault circuit interrupter
(GFCI) protected supply. Use of
a GFCI reduces the risk of electric
shock.
3) PERSONAL SAFETY
a) 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 inuence
of drugs, alcohol or medication.
A moment of inattention while
operating power tools may result in
serious personal injury.
b) Use personal protective
equipment. Always wear eye
protection. Protective equipment
such as dust mask, nonskid
safety shoes, hard hat, or hearing

protection used for appropriate
conditions will reduce personal
injuries.
c) 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
nger on the switch or energizing
power tools that have the switch on
invites accidents.
d) 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.
e) Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
f) 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.
g) 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
dustrelated hazards.
4) POWER TOOL USE AND CARE
a) 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.
b) 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.
c) 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.
d) 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.
e) 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 operation.
If damaged, have the power
tool repaired before use. Many
accidents are caused by poorly
maintained power tools.
f) Keep cutting tools sharp and
clean. Properly maintained cutting
tools with sharp cutting edges are
less likely to bind and are easier to
control.
g) Use the power tool, accessories
and tool bits, etc. in accordance
with these instructions, taking
into account the working
conditions and the work to be
performed. Use of the power tool
for operations different from those
intended could result in a hazardous
situation.
5) SERVICE
a) Have your power tool serviced by
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.
ADDITIONAL SAFETY RULES
FOR MITER SAWS

machine to slide, walk, or tip over,
causing serious injury.
• USE ONLY CROSSCUT SAW
BLADES recommended for miter saws.
For best results, do not use carbide
tipped blades with hook angles in
excess of 7 degrees. Do not use blades
with deep gullets. These can deect
and contact the guard, and can cause
damage to the machine and/or serious
injury.
• USE ONLY BLADES OF THE
CORRECT SIZE AND TYPE specied
for this tool to prevent damage to the
machine and/or serious injury.
• INSPECT BLADE FOR CRACKS or
other damage prior to operation. A
cracked or damaged blade can come
apart and pieces can be thrown at
high speeds, causing serious injury.
Replace cracked or damaged blades
immediately.
• CLEAN THE BLADE AND BLADE
CLAMPS prior to operation. Cleaning
the blade and blade clamps allows you
to check for any damage to the blade
or blade clamps. A cracked or damaged
blade or blade clamp can come apart
and pieces can be thrown at high
speeds, causing serious injury.
• DO NOT use lubricants or cleaners
(particularly spray or aerosol) in the
vicinity of the plastic guard. The plastic
material used in the guard is subject to
attack by certain chemicals.
• ALWAYS USE THE KERF PLATE
AND REPLACE THIS PLATE WHEN

Some dust created by
power sanding, sawing, grinding,
drilling, and other construction
activities contains chemicals known to
the State of California 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 lter out microscopic
particles.
• Avoid prolonged contact with
dust from power sanding, sawing,
grinding, drilling, and other
construction activities. Wear
protective clothing and wash
exposed areas with soap and water.
Allowing dust to get into your mouth,
eyes, or lay on the skin may promote
absorption of harmful chemicals.
Use of this tool can
generate and/or disperse dust, which
may cause serious and permanent
respiratory or other injury. Always
use NIOSH/OSHA approved respiratory
protection appropriate for the dust
exposure. Direct particles away from face
and body.
• Wear appropriate hearing protection
during use. Under some conditions and
duration of use, noise from this product
may contribute to hearing loss.
ALWAYS use safety
glasses. Everyday eye glasses are
NOT safety glasses. Also use face or
dust mask if cutting operation is dusty.
ALWAYS WEAR CERTIFIED SAFETY
EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CPA
Z94.3),
• ANSI S12.6 (S3.19) hearing
protection,
• NIOSH/OSHA respiratory protection.
• CLEAN THE MOTOR AIR SLOTS of
chips and sawdust. Clogged motor
air slots can cause the machine to
overheat, damaging the machine and
possibly causing a short which could
cause serious injury.
• KEEP ARMS, HANDS, AND FINGERS
AWAY FROM THE BLADE to prevent
severe cuts. Clamp all workpieces that
would cause your hand to be within 6"
(152 mm) of the saw blade.
• NEVER LOCK THE SWITCH IN THE
“ON” POSITION. Severe personal
injury may result.
• TURN OFF THE MACHINE and allow
the blade to come to a complete stop
before raising the arm and prior to
cleaning the blade area, removing
debris in the path of the blade, before
servicing or adjusting tool. A moving
blade can cause serious injury.
• PROPERLY SUPPORT LONG OR
WIDE WORKPIECES. Loss of control
of the workpiece can cause injury.
• NEVER CROSS ARMS IN FRONT OF
BLADE while using tool. Always make
a dry run (unpowered) before making
a nish cut so that you can check the
path of the blade or severe personal
injury may result.

ELECTRICAL
REQUIREMENTS AND
SAFETY
POWER SUPPLY AND MOTOR
SPECIFICATIONS
The AC motor used in this saw is a
universal, nonreversible type.
To avoid electrical
hazards, re hazards, or damage to the
tool, use proper circuit protection. Your
saw is wired at the factory for
120 V operation. Connect to a 120 V,
9 A circuit and use a 9 A time delay
fuse or circuit breaker. To avoid shock
or re, if power cord is worn or cut, or
damaged in any way, have it replaced
immediately.
DOUBLE INSULATED
The power tool is double insulated to
provide a double thickness of insulation
between you and tool’s electrical system.
All exposed metal parts are isolated from
the internal metal motor components with
protecting insulation.
Replacement parts – When servicing,
use only identical replacement parts.
Polarized plugs – This saw has a plug
that looks like the one shown below:
To reduce the risk of electrical shock,
this saw has a polarized plug (one blade
is wider than the other). This plug will t
in a polarized outlet only one way. If the
plug does not t fully in the outlet, reverse
the plug. If it still does not t, contact a
qualied electrician to install the proper
outlet. Do not change the plug in any way.
WARNING
!
WARNING
!Double insulation does
not take the place of normal safety
precautions when operating this tool.
To avoid electrocution:
• Use only identical replacement parts
when servicing a tool with double
insulation. Servicing should be
performed by a qualied technician.
• Do not use power tools in wet or damp
locations or expose them to rain or
snow.
MOTOR SAFETY PROTECTION
IMPORTANT
To avoid motor damage, the motor should
be blown out or vacuumed frequently to
keep sawdust from interfering with the
motor ventilation.
• Connect this saw to a 120 V circuit.
This circuit must not be less than a #18
wire with a 9 A time lag fuse.
• If the motor will not start, release the
trigger switch immediately. UNPLUG
THE SAW. Check the saw blade to
make sure it turns freely. If the blade
is free, try to start the saw again. If the
motor still does not start, refer to the
TROUBLESHOOTING GUIDE.
• If the tool suddenly stalls while cutting
wood, release the trigger switch,
unplug the tool and free the blade from
the wood. The saw may now be started
and the cut nished.
• FUSES may “blow” or circuit breakers
may trip frequently if:
• MOTOR is overloaded – overloading
can occur if you feed too rapidly or
make too many start/stops in a short
time.
• LINE VOLTAGE is more than 10%
above or below the nameplate
voltage rating. For heavy loads,
the voltage at motor terminals must
equal the voltage specied on the
nameplate.
• IMPROPER or dull saw blades are
used.
Polarized plugs

• Most motor troubles may be traced
to loose or incorrect connections,
overload, low voltage or inadequate
power supply wiring. Always check the
connections, the load and supply circuit
if the motor doesn’t run well. Check
minimum gauge for the length of cord
you are using on the chart below.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. 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. The
table below shows the correct size to use
depending on cord length and nameplate
ampere rating. If in doubt, use the next
heavier gauge. The smaller the gauge
number, the heavier the cord.
Be sure your extension cord is
properly wired and in good condition.
Always replace a damaged extension cord
or have it repaired by a qualied person
before using it. Protect your extension
cords from sharp objects, excessive heat
and damp or wet areas.
Use a separate electrical circuit for
your tools. This circuit must not be less
than a #18 wire with a 9 A time lag fuse.
NOTE: When using an extension cord on
a circuit with a #18 wire, the extension
cord must not exceed 25 feet in length.
Before connecting the tool 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.
