DON’T FORCE THE TOOL. It will do the job better and
safer at the feed rate for which it was designed.
USE THE RIGHT TOOL. Do not force the tool or
attachment to do a job for which it was not designed.
USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. Use only a
cord 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. A wire
gauge size (A.W.G.) of at least 14 is recommended for an
extension cord 25 feet or less in length. If in doubt, use
the next heavier gauge. The smaller the gauge number,
the heavier the cord.
DRESS PROPERLY. Do not wear loose clothing,
neckties, or jewelry that can get caught and draw you
into moving parts. Rubber gloves and nonskid footwear
are recommended when working outdoors. Also wear
protective hair covering to contain long hair.
ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-
resistant lenses, they are NOT safety glasses.
SECURE WORK. Use clamps or a vise to hold work when
practical, it is safer than using your hand and frees both
hands to operate the tool.
DO NOT OVERREACH. Keep proper footing and balance
at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and
clean for better and safer performance. Follow instructions
for lubricating and changing accessories.
DISCONNECT TOOLS. When not in use, before servicing,
or when changing attachments, blades, bits, cutters, etc.,
all tools should be disconnected from power source.

the tool is tipped or if the cutting tool is unintentionally
contacted.
CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly
and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage of
parts, mounting and any other conditions that may affect
its operation. A guard or other part that is damaged must
be properly repaired or replaced by an authorized service
center to avoid risk of personal injury.
USE THE RIGHT DIRECTION OF FEED. Feed work into
a blade, cutter, or sanding spindle against the direction
of rotation of the blade, cutter, or sanding spindle only.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
THE POWER OFF. Don't leave tool until it comes to a
complete stop.
PROTECT YOUR LUNGS. Wear a face or dust mask if
the cutting operation is dusty.
PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
DO NOT ABUSE CORD. Never carry tool by the cord or
yank it to disconnect from receptacle. Keep cord from
heat, oil, and sharp edges.
USE OUTDOOR EXTENSION CORDS. When tool is

location and keep it well away from the rotating blade.
INSPECT EXTENSION CORDS PERIODICALLY and
replace if damaged.
POLARIZED PLUGS. To reduce the risk of electric shock,
this tool 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.
KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND
GREASE. Always use a clean cloth when cleaning. Never
use brake fluids, gasoline, petroleum-based products, or
any solvents to clean tool.
STAY ALERT AND EXERCISE CONTROL. Watch what
you are doing and use common sense. Do not operate
tool when you are tired. Do not rush.
DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
USE ONLY CORRECT BLADES. Do not use blades with
incorrect size holes. Never use blade washers or blade
bolts that are defective or incorrect. The maximum blade
capacity of your saw is 10 in.
BEFORE MAKING A CUT, BE SURE ALL
ADJUSTMENTS ARE SECURE.
BE SURE BLADE PATH IS FREE OF NAILS. Inspect for
and remove all nails from lumber before cutting.
NEVER TOUCH BLADE or other moving parts during
use.
NEVER START A TOOL WHEN ANY ROTATING
COMPONENT IS IN CONTACT WITH THE WORKPIECE.

ELECTRICAL
DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
from the internal metal motor components with protecting
insulation. Double insulated tools do not need to be
grounded.
WARNING:
The double insulated system is intended to protect
the user from shock resulting from a break in the
tool’s internal wiring. Observe all normal safety
precautions to avoid electrical shock.
NOTE: Servicing of a product with double insulation requires
extreme care and knowledge of the system and should
be performed only by a qualified service technician. For
service, we suggest you return the tool to your nearest
authorized service center for repair. Always use original
factory replacement parts when servicing.
ELECTRICAL CONNECTION
This tool has a precision-built electric motor. It should be
connected to a power supply that is 120 V, AC only (normal
household current), 60 Hz. Do not operate this tool on
direct current (DC). A substantial voltage drop will cause a
loss of power and the motor will overheat. If the tool does
not operate when plugged into an outlet, double check the
power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the product will draw. An
undersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
When working outdoors with a product, use an extension
cord that is designed for outside use. This type of cord is
designated with “WA” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on
lumber, tools, or other obstructions while you are
working with a power tool. Failure to do so can
result in serious personal injury.
WARNING:
Check extension cords before each use. If
damaged replace immediately. Never use tool with
a damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.

ASSEMBLY
Depending on the cutting operation and the size of the
workpiece, it may be necessary to use a C-clamp instead of the
work clamp to secure the workpiece prior to making the cut.
To install the work clamp:
Place the shaft of the work clamp in either hole on the
miter table base.
Rotate the knob on the work clamp to move it in or out
as needed.
TO INSTALL THE BLADE
See Figure 12.
WARNING:
A 10 in. blade is the maximum blade capacity of
the saw. Never use a blade that is too thick to allow
outer blade washer to engage with the flats on the
spindle. Larger blades will come in contact with the
blade guards, while thicker blades will prevent the
blade bolt from securing the blade on the spindle.
Either of these situations could result in a serious
accident and can cause serious personal injury.

CUTTING A SLOT IN THE ZERO CLEARANCE
THROAT PLATE
In order to use your compound miter saw, you must cut
a slot through the zero clearance throat plate to allow for
blade clearance. To cut the slot, set your saw at 0° bevel,
turn saw on and allow the blade to reach full speed, then
carefully make a straight cut as far as it will go through the
throat plate. Turn your saw off and allow the blade to come
to a complete stop before raising the saw arm.
Adjust both sliding miter fences to insure proper clearance
prior to making a bevel cut. Set the bevel angle (right) to 48°,
turn your saw on and allow the blade to reach full speed,
then carefully make another cut through the zero clearance
throat plate. Next, set the bevel angle (left) to 48°, turn your
saw on and allow the blade to reach full speed, then carefully
make another cut through the zero clearance throat plate.
The slot in the throat plate will then be wide enough to allow the blade to pass through it at any angle from 0° to 48°.
Reset the position of the sliding miter fences.
the laser guide line at the same time, and will assist you in
lining up the mark for more accurate cutting of the workpiece.
Align the laser line and the mark with the saw arm at the
uppermost position. Once both lines are in alignment, do
not move the workpiece.
Remove the padlock. Make several practice cuts on different
styles and thickness of material. Repeat the steps above as
necessary.
Removing Your Mark:
Position the laser line near the left edge of your mark on the
work surface in order to remove the mark.
To Cut Your Mark:
Position the laser line near or over your mark on the work
surface in order to cut the mark.

in one of the positive stop notches, located in the miter
table base.
Place the workpiece flat on the miter table with one edge
securely against the fence. If the board is warped, place
the convex side against the fence. If the concave edge
of a board is placed against the fence, the board could
collapse on the blade at the end of the cut, jamming the
blade. See Figures 39 - 40.
When cutting long pieces of lumber or molding, support
the opposite end of the stock with a roller stand or with
a work surface level with the saw table. See Figure 29.
Align cutting line on the workpiece with the edge of saw
blade or laser line.
Grasp the stock firmly with one hand and secure it against
the fence. Use the work clamp or a C-clamp to secure
the workpiece when possible.
Before turning on the saw, perform a dry run of the cut-
ting operation to make sure that no problems will occur
when the cut is made.
Grasp the saw handle firmly. Squeeze the switch trigger.

OPERATION
TO COMPOUND MITER CUT
See Figure 28.
A compound miter cut is a cut made using a miter angle and
a bevel angle at the same time. This type of cut is used to
make picture frames, cut molding, make boxes with sloping
sides, and for certain roof framing cuts.
To make this type of cut the control arm on the miter table
must be rotated to the correct angle and the saw arm must
be tilted to the correct bevel angle. Care should always
be taken when making compound miter setups due to the
interaction of the two angle settings.
Adjustments of miter and bevel settings are interdependent
with one another. Each time you adjust the miter setting you
change the effect of the bevel setting. Also, each time you
adjust the bevel setting you change the effect of the miter
setting.
It may take several settings to obtain the desired cut. The
first angle setting should be checked after setting the second
angle, since adjusting the second angle affects the first.
Once the two correct settings for a particular cut have been
obtained, always make a test cut in scrap material before
making a finish cut in good material.
NOTE: It may be necessary to adjust or remove the sliding
miter fence to insure proper clearance prior to making the cut.
Pull out the lock pin and lift saw arm to its full height.
Lift themiterlockleveranddepressthedetentrelease
button to release the miter table.
Rotate the control arm until the pointer aligns with the
desired angle on the miter scale.
Release the detent release button, then push the miter
lock lever down to secure the miter table.
Loosen the bevel lock knob and move the saw arm to
the desired left bevel angle.
NOTE: To obtain right bevel angles, pull the bevel stop
pin out and tilt the saw to the desired right bevel angle.
Left and right bevel angles can be set from 0° to 48°.
NOTE: Use the bevel stop turret to locate 33.9°, 45°, and
48° bevel angles. See Figure 27.
Once the saw arm has been set at the desired angle,
securely tighten the bevel lock knob.
Recheck miter angle setting. Make a test cut in scrap
material.
Place the workpiece flat on the miter table with one edge
securely against the fence. If the board is warped, place

the convex side against the fence. If the concave edge
of a board is placed against the fence, the board could
collapse on the blade at the end of the cut, jamming the
blade. See Figures 39 - 40.
When cutting long pieces of lumber or molding, support
the opposite end of the stock with a roller stand or with
a work surface level with the saw table. See Figure 29.
Align the cutting line on the workpiece with the edge of
saw blade or laser line.
Grasp the stock firmly with one hand and secure it against
the fence. Use the work clamp or a C-clamp to secure
the workpiece when possible.
Before turning on the saw, perform a dry run of the cut-
ting operation to make sure that no problems will occur
when the cut is made.
Grasp the saw handle firmly. Squeeze the switch trigger.
Allow several seconds for the blade to reach maximum
speed.
Slowly lower the blade into and through the workpiece.
Release the switch trigger and allow the saw blade to
stop rotating before raising the blade out of workpiece
and removing the workpiece from the miter table.

OPERATION
TO SUPPORT LONG WORKPIECES
See Figure 29.
Long workpieces need extra supports. Supports should be
placed along the workpiece so it does not sag. The support
should let the workpiece lay flat on the base of the saw and
miter table during the cutting operation. Use the work clamp
or C-clamp to secure the workpiece.

OPERATION
CUTTING CROWN MOLDING
Your compound miter saw does an excellent job of cutting
crown molding. In general, compound miter saws do a better job of cutting crown molding than any other tool made.
In order to fit properly, crown molding must be compound
mitered with extreme accuracy.
The two contact surfaces on a piece of crown molding that
fit flat against the ceiling and the wall of a room 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°.
LAYING MOLDING FLAT ON THE MITER
TABLE
See Figure 31.
To use this method for accurately cutting crown molding for
a 90° inside or outside corner, lay the molding with its broad
back surface flat on the miter table and against the fence.
When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one angle changes the other angle as well.
Keep in mind that the angles for crown moldings are very
precise and difficult to set. Since it is very easy for these
angles to shift, all settings should first be tested on scrap
molding. Also most walls do not have angles of exactly 90°,
therefore, you will need to fine tune your settings.
When cutting crown molding by this method the bevel angle
should be set at 33.9°. The bevel stop turret can be used to
set the bevel angle to 33.9°. The miter angle should be set
at 31.6° either right or left, depending on the desired cut for
the application. See the chart below for correct angle settings
and correct positioning of crown molding on miter table.
The settings in the chart below can be used for cutting All
Standard (U.S.) crown molding with 52° and 38° angles. The
crown molding is placed flat on the miter table using the
compound features of your miter saw.

NESTING CROWN MOLDING AGAINST THE
MITER FENCE
See Figures 32 - 38.
To nest pieces of crown molding less than 4-5/8 in. tall:
Set the bevel angle at 0° and the miter angle at 45° to
either the left or the right.
Lay the crown molding on the saw with its bottom edge
resting at a natural angle flush against the fence and its
top edge resting flush against the miter table, this is called
“nesting”.
Position the crown molding in place by using the work
clamp as a material stop.
Tighten the knob on the work clamp until it rests lightly
against the edge of the molding. Do not overtighten as
this may move the material causing misalignment.
Before turning on the saw, perform a dry run of the cut-
ting operation to make sure that no problems will occur
when the cut is made.
Grasp the saw handle firmly. Squeeze the switch trigger.
Allow several seconds for the blade to reach maximum
speed.
Slowly lower the blade into and through the crown mold-
ing.
Release the switch trigger and allow the saw blade to stop
rotating before raising the blade out of the crown molding
and removing the crown molding from the miter table.
To nest pieces of crown molding that are 4-5/8 in. and
taller:
NOTE: This method of cut is for crown molding between
4-5/8 in. and 5-1/4 in. tall. Do not attempt to cut molding
that is larger than 5-1/4 in. tall.
Loosen the fence screw and slide miter fences toward
the saw arm until they are flush with the miter table.
Remove the sliding miter fences by pulling them up and
away from the miter table.
Place the left sliding miter fence on the right side of the
tool and the right sliding miter fence on the left side with
both fences facing the rear of the tool.
Install the miter fences by aligning the small slot in the
fences with the fixed screws on the saw and pushing
down.
NOTE: The fixed screws prevent the sliding miter fences
from sliding too close to the saw arm and possibly interfering with the movement of the blade. Do not remove
fixed screws.

ADJUSTMENTS
WARNING:
Before performing any adjustment, make sure the
tool is unplugged from the power supply. Failure to
heed this warning could result in serious personal
injury.
The compound miter saw has been adjusted at the factory for making very accurate cuts. However, some of the
components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will
probably become necessary due to wear. After unpacking
the saw, check the following adjustments before you begin
using saw. Make any readjustments that are necessary and
periodically check the parts alignment to make sure that the
saw is cutting accurately.
PIVOT ADJUSTMENTS
NOTE: These adjustments were made at the factory and
normally do not require readjustment.
TRAVEL PIVOT ADJUSTMENT
The saw arm should rise completely to the up position
by itself.
If the saw arm does not raise by itself or if there is play
in the pivot joints, have saw repaired at your nearest
AUTHORIZED SERVICE CENTER.
TO ADJUST THE BEVEL PIVOT
The compound miter saw should bevel easily by loosen-
ing the bevel lock knob and tilting the saw.
NOTE: To obtain right bevel angles, pull the bevel stop
pin out and tilt the saw to the desired angle.
If movement is tight or if there is play in the pivot, have
saw repaired at your nearest AUTHORIZED SERVICE
CENTER.
If the blade is out of square, adjust by tightening or loos-
ening the bevel stop adjustment screw.
Retighten bevel lock knob and push bevel stop pin in.
Recheck blade-to-table alignment.
NOTE: The above procedure can be used to check blade
squareness of the saw blade to the miter table at both
left and right 45° angles.
Your saw has several scale indicators. After squaring adjustments have been made, it may be necessary to loosen
the indicators screws and reset them to zero. See Figures
19 and 20.
