ELECTRICAL REQUIREMENT
POWER SUPPLY AND MOTOR SPECIFICATIONS
The AC motor used in this saw is a universal,
non reversible type. See “MOTOR” in the “PRODUCT
SPECIFICATIONS” section on page 2.
A WARNING
To avoid electrical hazards, fire hazards, or damage to
the tool, use proper circuit protection. Your saw is wired
at the factory for 120V operation. Connect to a 120V,
15 Amp circuit and use a 15 amp. time delay fuse or
circuit breaker. To avoid shock or fire, if power cord is
worn or cut, or damaged in any way, have it replaced
immediately.
EŒCTRICAL REQUIREMENTS AND SAP
ELECTRICAL REQUIREMENTS - conf d
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 ike
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 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 the
proper outlet. Do not change the plug in any way.
A WARNING
Double insulation does not take the place of normal
safety precautions when operating this tool.
To avoid electrocution:
1. Use only identical replacement parts when
servicing a too! with double insulation. Servicing
should be performed by a qualified technician.
2. 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 ventiiation.
1. CONNECT this saw to a 120V, 15 amp. circuit with a
15 amp. time delay fuse or circuit breaker. Using the
wrong size fuse can damage the motor.
2. If the motor won’t 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”
3. 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 finished
4. FUSES may “blow” or circuit breakers may trip
frequently if:
a. MOTOR is overloaded - overloading can occur if
you feed too rapidly or make too many start/stops
in a short time.
b. 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 specified on the nameplate.
c. IMPROPER or dull saw blades are used.
5. 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 cause 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 ts properly wired and
in good condition. Always replace a damaged extension
cord or have it repaired by a qualified 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 # 12 wire and should
be protected with a 15 Amp time delay fuse. 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.

ALIGNING THE LASER BEAM
A WARNING
For your own safety, never connect the plug to
power source outlet until all the adjustment steps
are complete and you have read and understood the
safety and operational instructions.
The laser beam must always be correctly aligned with
the blade to ensure straight, even cutting.
Your tool is equipped with the Laser Trac® cutting
guide using Class Ilia laser beams. The laser beam will
enable to preview the saw blade path on the stock to
be cut before starting the miter saw. This laser guide is
powered by the transformed alternating current supply
directly through the power lead. The saw must be
connected to the power source and the laser on/off
switch must be turned on for the laser line to show.
A WARNING
AVOID DIRECT EYE CONTACT
Laser radiated when laser guide is turned on. Avoid
direct eye contact. Always un-plug the miter saw
from power source before making any adjustments.
{1). Start with the set screw on the left side of the
laser assembly, then with the front set screw on the
right side of the laser assembly.
Fig. N-1
NOTE; All the adjustments for the operation of this
machine have been completed at the factory. Due to
normal wear and use, some occasional readjustments
may be necessary.
A. Check Laser Beam Alignment
1. Mark a 90° straight line across a board to serve as a
“pattern line” to test laser alignment. Lay the board
on the miter table.
2. Plug saw into outlet and turn on the laser beam and
line it up with the pattern line.
3. Lower saw blade to pattern line and if blade is
not flush with the pattern tine, adjust as follows in
procedures (B).
B. Adjusting the Angie of the Laser Trac® (Fig. N-2)
1. Turn the laser element (1) in the desired direction
to adjust the laser angle. NOTE: Do not adjust the
laser more than !4 turn in either direction as this may
damage the laser. There are two flat sides on the
laser element where you can position an adjustable
wrench for your adjustment.
C. Aligning The Laser Beam
1. Loosen only ’/2 turn at a time the three set screws (1).
2. Adjust laser by turning the left side set screw
clockwise to shift the laser line to the right. To shift
the laser tine to the left, turn the right side set screws

16
PLAN YOUR WORK
• Use the right tool. Don’t 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, fixed position.
CAUTION: This machine is not designed for cutting
masonry, masonry products, ferrous metals (steel,
iron, and iron-based metals.) Use this miter saw to
cut only wood, wood-like products, or non-ferrous
metals. 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 fire. 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.
• 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.
Pian the way you will grasp the workpiece from
start to finish. Avoid awkward operations and hand
positions. A sudden slip could cause your fingers or
hand to move into the blade.
• 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’s practical.
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
fingers to be within 6-3/4 inches of the saw blade
the workpiece is too small. Keep hands and
fingers 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
flat or be held by a fixture 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”.
A WARNING
To avoid injury, follow all applicable safety
instructions, when cutting non-ferrous metals:
• Use only saw blades specifically recommended
for non-ferrous metal cutting.
• Do not cut metal workpieces that must be hand
held. Clamp workpieces securely.
• Cut non-ferrous metals only if you are under the
supervision of an experienced person and the
dust bag has been removed from the saw.
WHEN SAW IS RUNNING
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 firmly against the fence
and table stop so it will not rock or twist during
the cut.
• Make sure there is no debris between the
workpfec=& and the table or fence.
A WARNING
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 finding and
correcting the problem.
17
BODY AND HAND POSITION {FIG. P)
• 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.
Place hand at least 6-3/4 in. away from the path
of the blade, out of the “No-Hands Zone.“ Hold
workpiece firmly against the fence to prevent
movement toward the blade. Before making a cut,
with the power switch in the OFF position bring the
saw blade down to the workpiece to see the cutting
path of the blade.
• Press in lock-off switch in trigger switch handfe.
• Squeeze trigger switch to start saw.
• Lower blade into workpiece.
• Keep children away. Keep ail visitors a safe distance
from the miter saw. Make sure bystanders are dear
of the miter saw and workpiece.
• Don’t force tool. It will do the job better and safer at
its designed rate. Feed the saw into the workpiece
slowly with a firm downward motion.
• Before freeing jammed material.
• Release Trigger Switch.
• Unplug the miter saw.
• Wait for ail moving parts to stop.
• After finishing a cut:
• Holding the cutting arm in the down position.
• Release the switch, and wait for ail moving parts
to stop before moving your hands and before
raising the cutting arm.
• If the blade doesn’t stop within 6 seconds, unplug
the saw and follow the instructions in
TROUBLESHOOTING GUIDE section for
adjusting the blade brake before using the saw
again.
• Release the trigger switch, and wait for all moving
parts to stop before moving your hands and raising
cutting arm.

to a 45° left bevel.
3. Tighten the bevel lock handle (1) to lock the cutting
head in position.
Fig. S
CUTTING BOWED MATERIAL (FIG. U)
A bowed workpiece must be positioned against the
fence and secured with a clamping device 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.

AUXILARY WOOD FENCE (FIG. W)
When making multiple or repetitive cuts that result in
cut-off pieces of one inch or less, it is possible for the
saw blade to catch the cut-off piece and throw it out of
the saw or into the blade guard and housing, possibly
causing damage or injury. To minimize this, an auxiliary
wood fence can be mounted to your saw. Holes are
provided in the saw fence to attach an auxiliary wood
fence. This fence is constructed of straight auxiliary
wood approximately 3/4 inch thick by 2-1/2 inches high
by 16-1/8 inches long.
Attach the wood fence securely and make a full depth
cut to make a blade slot. Check for interference between
the wood fence and the lower blade guard. Adjust if
necessary. NOTE: This auxiliary fence is used only with
the saw blade in the 0° bevel position (90° to the table).
The auxiliary wood fence must be removed when bevel
cutting.

CUTTING BASE MOLDING (FIG. Z)
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:
1. Always make sure moldings rest firmly against fence
and table. Use hold-down or C-damps, whenever
possible, and place tape on the area being clamped
to avoid marks.
2. Reduce splintering by taping the cut area prior to
making cut. Mark cut line directly on the tape.
3. Splintering typically happens due to wrong blade
application and thinness of the material.
21
CUTTING CROWN MOLDING (FIG. AA,BB)
NOTE; The chart below references a compound
cut for crown molding ONLY WHEN THE ANGLE
BETWEEN THE WALLS EQUALS EXACTLY 90°.
Your compound miter saw is suited for the difficult task
of cutting crown molding. To fit properly, crown molding
must be compound-mitered with extreme accuracy.
The two surfaces on a piece of crown molding that fit
flat against the ceiling and wall are at angles that, when
added together equal exactly 90°.
Most crown molding has a top rear angle (the section
that fits flat against the ceiling) of 52°and a bottom rear
angle (the section that fits flat against the wall) of 38°.
In order to accurately cut crown molding for a 90°
Inside or outside comer, lay the molding with its broad
back surface flat on the saw table.
When setting the bevel and miter angles for compound
miters, remember that the settings are interdependent;
changing one changes the other, as well. Also keep in
mind that the angles from crown molding are very easy
for these angles to shift slightly, all settings should be
tested on scrap molding.
