GENERAL POWER TOOL
SAFETY RULES
Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions may result in
electric shock, re and/or serious injury.
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. Unmodied plugs and
matching outlets will reduce risk of
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.
WARNING

WARNING
!
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 inuence
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

SAFETY INSTRUCTIONS FOR
MITER SAWS
• Miter saws are intended to cut wood
or wood-like products, they cannot
be used with abrasive cut-off wheels
for cutting ferrous material such as
bars, rods, studs, etc. Abrasive dust
causes moving parts such as the lower
guard to jam. Sparks from abrasive
cutting will burn the lower guard, the
kerf insert and other plastic parts.
• Use clamps to support the workpiece
whenever possible. If supporting the
workpiece by hand, you must always
keep your hand at least 100 mm from
either side of the saw blade. Do not
use this saw to cut pieces that are
too small to be securely clamped or
held by hand. If your hand is placed
too close to the saw blade, there is
an increased risk of injury from blade
contact.
• The workpiece must be stationary
and clamped or held against both the
fence and the table. Do not feed
the workpiece into the blade or cut
"freehand" in any way. Unrestrained
or moving workpieces could be thrown
at high speeds, causing injury.
WARNING
!
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
dust-related 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 qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.
People with electronic devices, such
as pacemakers, should consult their
physician(s) before using this product.
Operation of electrical equipment in
close proximity to a heart pacemaker
could cause interference or failure of
the pacemaker.

• Push the saw through the workpiece.
Do not pull the saw through the
workpiece. To make a cut, raise the
saw head and pull it out over the
workpiece without cutting, start the
motor, press the saw head down and
push the saw through the workpiece.
Cutting on the pull stroke is likely to
cause the saw blade to climb on top of
the workpiece and violently throw the
blade assembly towards the operator.
• Never cross your hand over the
intended line of cutting either in front
or behind the saw blade. Supporting
the workpiece "cross handed" i.e.
holding the workpiece to the right of the
saw blade with your left hand or vice
versa is very dangerous.
• Do not reach behind the fence with
either hand closer than 100 mm
from either side of the saw blade, to
remove wood scraps, or for any other
reason while the blade is spinning.
The proximity of the spinning saw blade
to your hand may not be obvious and
you may be seriously injured.
• Inspect your workpiece before
cutting. If the workpiece is bowed
or warped, clamp it with the outside
bowed face toward the fence. Always
make certain that there is no gap
between the workpiece, fence and
table along the line of the cut. Bent
or warped workpieces can twist or shift
and may cause binding on the spinning
saw blade while cutting. There should
be no nails or foreign objects in the
workpiece.
• Do not use the saw until the table is
clear of all tools, wood scraps, etc.,
except for the workpiece. Small debris
or loose pieces of wood or other objects
that contact the revolving blade can be
thrown with high speed.
• Cut only one workpiece at a time.
Stacked multiple workpieces cannot be
adequately clamped or braced and may
bind on the blade or shift during cutting.
• Ensure the miter saw is mounted or
placed on a level, rm work surface
before use. A level and rm work
surface reduces the risk of the miter
saw becoming unstable.
• Plan your work. Every time you
change the bevel or miter angle
setting, make sure the adjustable
fence is set correctly to support the
workpiece and will not interfere with
the blade or the guarding system.
Without turning the tool "ON" and with
no workpiece on the table, move the saw
blade through a complete simulated cut
to assure there will be no interference or
danger of cutting the fence.
• Provide adequate support such as
table extensions, saw horses, etc. for
a workpiece that is wider or longer
than the table top. Workpieces longer
or wider than the miter saw table can
tip if not securely supported. If the
cut-off piece or workpiece tips, it can
lift the lower guard or be thrown by the
spinning blade.
• Do not use another person as a
substitute for a table extension or as
additional support. Unstable support
for the workpiece can cause the blade
to bind or the workpiece to shift during
the cutting operation pulling you and the
helper into the spinning blade.
• The cut-off piece must not be
jammed or pressed by any means
against the spinning saw blade. If
conned, i.e. using length stops, the
cut-off piece could get wedged against
the blade and thrown violently.
• Always use a clamp or a xture
designed to properly support round
material such as rods or tubing. Rods
have a tendency to roll while being cut,
causing the blade to "bite" and pull the
work with your hand into the blade.
• Let the blade reach full speed before
contacting the workpiece. This will
reduce the risk of the workpiece being
thrown.
• If the workpiece or blade becomes
jammed, turn the miter saw off. Wait
for all moving parts to stop and
disconnect the plug from the power
source and/or remove the battery
pack. Then work to free the jammed
material. Continued sawing with a
jammed workpiece could cause loss of
control or damage to the miter saw.
• After nishing the cut, release the
switch, hold the saw head down
and wait for the blade to stop before
removing the cut-off piece. Reaching
with your hand near the coasting blade
is dangerous.
• Hold the handle rmly when making
an incomplete cut or when releasing
the switch before the saw head is
completely in the down position. The
braking action of the saw may cause
the saw head to be suddenly pulled
downward, causing a risk of injury.

• Do not use this saw to cut tree limbs
or logs.
• Never use blades recommended for
operation at less than 5000 RPM.
• Do not use this saw to cut ber cement
board. This miter saw is not intended to
cut ber cement board.

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.
ELECTRICAL REQUIREMENTS -
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
qualied 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 qualied 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, 9 A circuit
with a 9 A time-delay fuse or circuit
breaker. Using the wrong size fuse can
damage the motor.
• 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 specied on the
nameplate.
• IMPROPER or dull saw blades are
used.

• 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 qualied 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.

blade while it is spinning.
• Remove adjusting wrench from the tool
before turning it on.
• To avoid injury from jams, slips, or
thrown pieces, use only recommended
accessories.
RECOMMENDED ACCESSORIES
• Follow the instructions that come with
the accessory. The use of improper
accessories may cause risk of injury
to persons.
• Choose the correct 7-1/4 in. diameter
blade (with a 5/8 inch round arbor hole,
and no more that 7 degree hook angle)
for the material and the type of cutting
you plan to do. Do not use thin kerf
blades.
• Make sure the blade is sharp,
undamaged and properly aligned. With
the saw unplugged, push the cutting
arm all the way down. Manually spin
the blade and check for clearance. Tilt
the power-head to a 45° bevel and
repeat the test.

20
• Wear non-slip footwear.
• Tie back long hair.
• Roll long sleeves above the elbow.
• Noise levels vary widely. To avoid
possible hearing damage, wear ear
plugs when using any miter saw.
• For dusty operations, wear a dust mask
along with safety goggles.
INSPECT YOUR WORKPIECE
Make sure there are no nails or foreign
objects in the part of the workpiece
being cut.
Plan your work to avoid small pieces that
may bind, or that are too small to clamp
and get a solid grasp on. Plan the way
you will grasp the workpiece from start
to nish. Avoid awkward operations and
hand positions. Keep your hands at least
6 inches away from the blade path.
A sudden slip could cause your ngers
or hand to move into the blade.
TO ENSURE THE BLADE PATH IS
CLEAR OF OBSTRUCTIONS, ALWAYS
MAKE A DRY RUN OF THE CUT
WITHOUT POWER BEFORE MAKING
ANY CUTS ON THE WORKPIECE.
DO NOT OVER-REACH
Keep good footing and balance. Keep
your face and body to one side, out of the
line of a possible kickback. NEVER stand
in the line of the blade.
Never cut freehand:
• Brace your workpiece rmly against the
fence and table stop so it will not rock
or twist during the cut.
• Make sure there is no debris between
the workpiece and the table or fence.
• Make sure there are no gaps between
the workpiece, fence and table that will
let the workpiece shift after it is cut.
• Keep the cut off piece free to move
sideways after it is cut off. Otherwise,
it could get wedged against the blade
and thrown violently.
• Only the workpiece should be on the
saws table.
• Secure work. Use clamps or a vise to
help hold the work when it is practical.
WARNING
!
KEEP YOUR WORK AREA CLEAN
Cluttered areas and benches invite
accidents.
To avoid burns or other
re damage, never use the miter saw
near ammable liquids, vapors, or
gases.
• Plan ahead to protect your eyes,
hands, face and ears.
• Know your miter saw. Read and
understand the Instruction Manual
and labels afxed to the tool. Learn
its application and limitations as well
as the specic potential hazards
peculiar to this tool. To avoid injury from
accidental contact with moving parts,
do not do layout, assembly, or setup
work on the miter saw while any parts
are moving.
• Avoid accidental starting, make sure
the trigger switch is disengaged before
plugging the miter saw into a power
outlet.
PLAN YOUR WORK
• Use the right tool. Do not force a tool
or attachment to do a job it was not
designed to do. Use a different tool for
any workpiece that can’t be held in a
solidly braced, xed position.
This machine is not
designed for cutting masonry, masonry
products, metals. Use this miter saw to
cut only wood, or wood-like products.
Other material may shatter, bind the
blade, or create other dangers. Remove
all nails that may be in the workpiece
to prevent sparking that could cause
a re. Remove dust bag when cutting
non-ferrous metals.
DRESS FOR SAFETY
Any power tool can throw foreign
objects into the eyes. This can result
in permanent eye damage. Everyday
eyeglasses have only impact resistant
lenses and are not safety glasses.
Glasses or goggles not in compliance with
ANSI Z87.1 could seriously injure you
when they break.
• Do not wear loose clothing, gloves,
neckties or jewelry (rings, watches).
They can get caught and draw you into
moving parts.
WARNING
!
CAUTION
!
21
USE EXTRA CAUTION WITH LARGE
OR ODD SHAPED WORKPIECES
• Use extra supports (tables, sawhorses,
blocks, etc.) for workpieces large
enough to tip.
• Never use another person as a
substitute for a table extension, or as an
additional support for a workpiece that
is longer or wider than the basic miter
saw table, or to help feed, support, or
pull the workpiece.
• Do not use this saw to cut small pieces.
If the workpiece being cut would cause
your hand or ngers to be within 6 in.
of the saw blade the workpiece is too
small. Keep hands and ngers out of
the “no hands zone” area marked on
the saws table.
• When cutting odd shaped workpieces,
plan your work so it will not bind in
the blade and cause possible injury.
Molding, for example, must lie at or be
held by a xture or jig that will not let it
move when cut.
• Properly support round material such
as dowel rods, or tubing, which have
a tendency to roll when cut, causing
the blade to “bite”. This is especially
important when making angle cuts.
• NEVER tie, tape or hold the guard open
when operating the saw.
A workpiece that is
clamped, balanced and secure before
a cut may become unbalanced after
a cut is completed. An unbalanced
load may tip the saw or anything the
saw is attached to, such as a table or
workbench. When making a cut that
may become unbalanced, properly
support the workpiece and ensure the
saw is rmly bolted to a stable surface.
Personal injury may occur.
The clamp foot must
remain clamped above the base of
the saw whenever the clamp is used.
Always clamp the workpiece to the
base of the saw – not to any other part
of the work area. Ensure the clamp foot
is not clamped on the edge of the base
of the saw.
Always use a work clamp
to maintain control and reduce the risk
of workpiece damage and personal
injury.
WHEN SAW IS RUNNING
Do not allow familiarity
from frequent use of your miter saw to
result in a careless mistake. A careless
fraction of a second is enough to
cause a severe injury. Before cutting,
if the saw makes an unfamiliar noise
or vibrates, stop immediately. Turn
the saw OFF. Unplug the saw. Do not
restart until nding and correcting
the problem.
BODY AND HAND POSITION
(FIGURE S, T, U, V, W)
Never place hands near the cutting
area. Proper positioning of your
body and hands when operating the
miter saw will make cutting easier and
safer. Keep children away. Keep all
visitors at a safe distance from the miter
saw. Make sure bystanders are clear of
the saw and workpiece. Do not force the
saw. It will do the job better and safer at
its designed rate.
ALWAYS MAKE DRY RUNS
(UNPOWERED) BEFORE FINISH CUTS
SO THAT YOU CAN CHECK THE PATH
OF THE BLADE. DO NOT CROSS
HANDS, AS SHOWN IN FIGURE S, T, U
& V.

CUTTING BOWED MATERIAL
(FIGURE BB)
To avoid injury from
materials being thrown, always unplug
the saw to avoid accidental starting
and remove small pieces of material
from the table cavity.
• The table insert may be removed for
this purpose, but always reattach table
insert prior to performing a cutting
operation.
• A bowed workpiece (1) must be
positioned against the fence and
secured with a clamping device (2) as
shown before cutting. Do not position
workpiece incorrectly or try to cut the
workpiece without the support of the
fence. This will cause the blade to bind
and could result in personal injury.
WORKPIECE SUPPORT (FIGURE CC)
Long pieces need extra support. The
support should be placed under the
workpiece. Keep your hand holding the
workpiece positioned 6-3/4 inches or more
away from the blade. The support must
let the workpiece lay at on the work table
during the cutting operation.
NOTE: When mounted on a at surface,
the saw table is 2-4/5 inches high.

WARNING
!
CUTTING BASE MOLDING
(FIGURE DD)
Base moldings and many other moldings
can be cut on a compound miter saw.
The setup of the saw depends on molding
characteristics and application, as shown.
Perform practice cuts on scrap material to
achieve best results:
• Always make sure moldings rest rmly
against fence and table. Use hold-down,
crown molding vise or C-clamps,
whenever possible, and place tape on
the area being clamped to avoid marks.
• Reduce splintering by taping the cut
area prior to making the cut. Mark the
cut line directly on the tape.
• Splintering typically happens due to an
incorrect blade application and thinness
of the material.
NOTE: Always perform a dry run cut so
you can determine if the operation being
attempted is possible before power is
applied to the saw.
CUTTING CROWN MOLDING
(FIGURE EE, FF)
Your compound miter saw is suited for
the difcult task of cutting crown molding.
To t properly, crown molding must be
compound-miterd with extreme accuracy.
The two surfaces on a piece of crown
molding that t at against the ceiling and
wall are at angles that, when added
together equal exactly 90°.

Replace for the other side. To reassemble
reverse the procedure. The ears on the
metal end of the assembly go in the same
hole the carbon part ts into. Tighten the
cap snugly, but do not overtighten. Repeat
for the carbon brush located on the other
side of motor.
NOTE: To reinstall the same brushes,
rst make sure the brushes go back in
exactly the way they came out. This will
avoid a break-in period that reduces motor
performance and increases wear.
LOWER BLADE GUARD
Do not use the saw without the lower
blade guard. The lower blade guard is
attached to the saw for your protection.
Should the lower guard become
damaged, do not use the saw until the
damaged guard has been replaced.
Develop a regular check to make sure
the lower guard is working properly.
Clean the lower guard of any dust or
buildup with a damp cloth.
• When cleaning the lower guard,
unplug the saw from the power
source receptacle to avoid
unexpected startup.
•
Do not use solvents on the guard.
They could make the plastic “cloudy”
and brittle.
SAWDUST
Periodically, sawdust will accumulate
under the work table and base. This
could cause difculty in the movement
of the worktable when setting up
a miter cut. Frequently blow out or
vacuum up the sawdust.
MAINTENANCE
•
To reduce the risk of injury, turn unit
off and disconnect it from power
source before installing and removing
accessories, before adjusting or
when making repairs. An accidental
start-up can cause injury.
•
DO NOT touch the sharp points on
the blade with ngers or hands while
performing any maintenance.
•
To avoid injury, never put lubricants
on the blade while it is spinning.
•
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.
•
To avoid re or toxic reaction, never
use gasoline, naphtha acetone,
lacquer thinner or similar highly
volatile solvents to clean the miter
saw.
•
To avoid injury from unexpected
starting or electrical shock, unplug
the power cord before working on
the saw.
•
For your safety, this saw is double
insulated. To avoid electrical shock,
re or injury, use only parts identical
to those identied in the parts list.
Reassemble exactly as the original
assembly to avoid electrical shock.
REPLACING CARBON BRUSHES
(FIGURE GG)
The carbon brushes furnished will last
approximately 50 hours of running time,
or 10,000 ON/OFF cycles. Replace both
carbon brushes when either has less than
1/4 in. length of carbon remaining, or if
the spring or wire is damaged or burned.
To inspect or replace brushes, rst unplug
the saw. Then remove the plastic cap (1)
on the side of the motor (2). Remove the
cap cautiously, because it is springloaded.
Then pull out the brush and replace.
