Important Safety Instructions
always be followed to reduce risk of fire, electric shock, and personal injury,
A WARNING: When using electric tools, basic safety precautions should
including the following:
READ ALL INSTRUCTIONS
Double Insulation
Double insulated tools are constructed throughout with two separate layers of electrical
insulation or one double thickness of insulation between you and the tool's electrical sys-
tem. Tools built with this insulation system are not intended to be grounded. As a result,
your tool is equipped with a two prong plug which permits you to use extension cords with-
out concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety precautions when oper-
ating this tool. The insulation system is for added protection against injury resulting from a
possible electrical insulation failure within the tool.
i_CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS.
Repair or replace damaged cords.
Polarized Plugs
Polarized plugs (one blade is wider than the other) are used on equipment to reduce the
risk of electric shock. When provided, this plug will fit in the 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.
Safety Instructions For All Tools
• KEEP GUARD IN PLACE and in working order.
• REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that
keys and adjusting wrenches are removed from spindle before turning tool on.
• KEEP WORKAREA CLEAN. Cluttered areas and benches invite accidents.
• DON'T USE IN DANGEROUS ENVIRONMENT. Don't use power tools in damp or wet
locations, or expose them to rain or snow. Keep work area well lighted.
• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.
• MAKE WORKSHOP KID PROOF with padlocks, master switches, or by removing
starter keys.
• DON'TFORCE TOOL. It will do the job better and be safer at the rate for which it was
designed.
• USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not
designed.
• WEAR PROPER APPAREL. No loose clothing, gloves, neckties, rings, bracelets, or
other jewelry to get caught in moving parts. Non-slip footwear is recommended. Wear
protective hair covering to contain long hair. Air vents may cover moving parts and
should also be avoided.
• ALWAYS WEAR SAFETYGLASSES. Also use face or dust mask if cutting operation
is dusty. Everyday eyeglasses have only impact resistant lenses, they are NOT safety
glasses.
• SECURE WORK. Use clamps or vise when you cannot secure the workpiece on the
table and against the fence by hand or when your hand will be dangerously close to the
blade (within 6").
• DON'T OVERREACH. Keep proper footing and balance at all times.
• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest per-
formance. Follow instructions for lubricating and changing accessories.
• DISCONNECT TOOLS before servicing; when changing accessories such as blades,
bits, cutters, etc.
• REDUCE THE RISK OF UNINTENTIONAL STARTING. Make sure switch is in OFF
position before plugging in.
• USE RECOMMENDEDACCESSORIES. Consult the instruction manual for recom-
mended accessories. The use of improper accessories may cause risk of injury to per-
sons.
• NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cut-
ting 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 per-
form 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 opera-
tion. A guard or other part that is damaged should be properly repaired or replaced. Do
not use tool if switch does not turn it on and off.
• NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't leave
tool until it comes to a complete stop.
• DO NOT OPERATE ELECTRIC TOOLS NEAR FLAMMABLE LIQUIDS OR IN
GASEOUS OR EXPLOSIVE ATMOSPHERES. Motors in these tools may spark and
ignite fumes.
• EXTENSION CORDS. 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 following table shows the correct size to use depending on cord
length and nameplate ampere rating, ff in doubt, use the next heavier gage. The small-
er the gage number, the heavier the cord.

Additional Safety Rules For Miter Saws
A CAUTION: FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL
INJURYAND SERIOUS DAMAGE TO THE SAW.
• DO - Protect electric supply line with at least a 15 ampere time-delay fuse or a circuit
breaker.
• DO - Make certain the blade rotates in the correct direction and that the teeth at the bot-
tom of the blade are pointing to the rear of the miter saw.
• DO - Be sure all clamp handles are tight before starting any operation.
• DO - Be sure all blade and clamp washers are clean and recessed sides of collars are
against blade. Tighten arbor screw securely.
• DO - Keep saw blade sharp.
• DO - Keep motor air slots free of chips and dirt.
• DO - Use blade guards at all times.
• DO - Keep hands outofpath ofsawblade.
• DO - Shut offpower, disconnect cord from power source and wait for saw blade to stop
before servicing or adjusting tooL
• DO - Support long work with an outboard tool rest.
• DON'T -Attempt to operate on anything but designated voltage.
• DON'T - Operate unless all clamp handles are tight.
• DON'T - Use blades larger or smaller than those which are recommended.
• DON'T - Wedge anything against fan to hold motor shaft.
• DON'T- Force cutting action. (Stalling orpartial stalling of motor can cause major dam-
age. Allow motor to reach full speed before cutting.)
• DON'T - Cut ferrous metals (Those with any iron or steel content) or any masonry.
• DON'T- Use abrasive wheels. The excessive heat and abrasive particles generated by
them will damage the saw.
• DON'T - Allow anyone to stand behind saw.
• DON'T - Apply lubricants to the blade when it's running.
• DON'T - Place either hand in the blade area when the saw is connected to the power
source.
• DON'T - Use blades rated less than 4800 R.P.M.
• DO NOT - Cut small pieces without clamping. Keep hands 6" or more from blade.
• DON'T - Operate saw without guards in place.
• DON'T- Perform any operation freehand.
• DON'T - Reach around or behind saw blade.
• DON'T - Place hands closer than 6 inches from the saw blade.
• DO NOT - Reach underneath the saw unless it is turned off and unplugged. The saw
blade is exposed on the underside of the saw.
• DO NOT - Move either hand from saw or workpiece or raise arm until blade has
stopped.
• DO NOT- Use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the
plastic guard. The polycarbonate material used in the guard is subject to attack by cer-
tain chemicals.
• Never use without kerf plate, and replace when kerf plate is damaged because small
chip accumulation under saw may interfere with saw blade or may cause instability of
workpiece when cutting.
_ CAUTION: Do not connect unit to electrical power source until complete instructions are
read and understood.
_CAUTION: Wear appropriate personal hearing protection during use. Under some
conditions and duration of use, noise from this product may contribute to hearing loss.
_ WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known 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 (CCA).
Your risk from these exposures varies, depending on how often you do this type of work.
Toreduce 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 filter
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.
A WARNING: Use of this tool can generate and/or disburse dust, which may cause seri-
ous and permanent respiratory or other injury Always use NIOSH/OSHA approved respi-
ratory protection appropriate for the dust exposure. Direct particles away from face and
body.

Electrical Connection
Be sure your power supply agrees with the nameplate marking. 120 volts, AC means that
your saw will operate on alternating current. The switch is suseptible to failure if direct cur-
rent is used. Avoltage decrease of 10 percent or more will cause a loss of power and over-
heating. All DEWALT tools are factory tested. Ifthis tool does not operate, check the power
supply.

Familiarization
Your miter saw is fully FIG. 1
assembled in the carton.
Open the box and lift the
saw out by the con-
venient carrying handle,
as shown in Figure 1.
Place the saw on a
smooth, flat surface such
as a workbench or strong table. FIG.2
Examine the two figures on page 6
to become familiar with the saw
and its various parts. The section
on adjustments will refer to these
terms and you must know what
and where the parts are.
Press down lightly on the operating
handle and pull out the lock down
pin. Gently release the downward
pressure and hold the arm allowing
it to rise to its full height. Use the
lock down pin when carrying the
saw from one place to another.
Always use the carrying handle to transport the saw or the
hand indentations shown in Figure. 2.
Bench Mounting
Holes are provided in all 4 feet to facilitate bench mount-
ing, as shown in Figure 4. (Two different sized holes are
provided to accommodate different sizes of screws. Use
either hole, it is not necessary to use both.) Always mount
your saw firmly to a stable surface to prevent movement.
To enhance the tool's portability, it can be mounted to a
piece of 1/2" or thicker plywood which can then be
clamped to your work support or moved to other job sites
and reclamped.
NOTE: If you elect to mount your saw to a piece of ply-
wood, make sure that the mounting screws don't protrude
from the bottom of the wood. The plywood must sit flush on
the work support. When clamping the saw to any work sur-
face, clamp only on the clamping bosses where the mount-
ing screw holes are located. Clamping at any other point
will surely interfere with the proper operation of the saw.
_, CAUTION: To prevent binding and inaccuracy, be sure
the mounting surface is not warped or otherwise uneven.
If the saw rocks on the surface place a thin piece of mate-
rial under one saw foot until the saw sits firmly on the
mounting surface.

screw to hold bracket in place.
WARNING:
• The guard bracket must be returned to its original position
and the screw tightened before activating the saw.
• Failure to do so may allow the guard to contact the spinning
saw blade resulting in damage to the saw and severe
personal injury.
Transporting the Saw
TURN OFF AND UNPLUG THE MITER SAW BEFORE ATTEMPTING TO MOVE IT OR
MAKE ANY ADJUSTMENTS WHAT SO EVER!
In order to conveniently carry the miter saw from place to place, a carrying handle has
been included on the top of the saw arm and hand indentations in the base, as shown in
Figure 4.

(FIG. 8)
Your saw has two 45 degree bevel adjustments, one for
the right, and one for the left. The procedure is the same
for each.
To align the 45 degree stops, lock the arm in the down
position. Place a speed square against the blade and table
taking care to not have the square not touch a blade tooth.
Loosen the bevel lock lever and ensure the bevel latch has
firmly snapped into place at 45 degrees. If the saw blade
is not 45 degrees to the table, loosen the nut which holds
the 45 bevel latch plate to the table. Rotate the adjustment
screw counterclockwise one or two turns so that the blade
is less than 45 degrees to the table. Turn the adjustment
screw clockwise until the blade is 45 degrees to the table.
Tighten the lock nut.

FENCE ADJUSTMENT (FIG. 9)
Turn Off and Unplug the Miter Saw.
In order that the saw can bevel to a full 48 degrees left or
right, one of the fences can be adjusted to provide clear-
ance. To adjust the fences, loosen a plastic knob and slide
the fence outward. Make a dry run with the saw turned off
and check for clearance. Adjust the fence to be as close to
the blade as practical to provide maximum workpiece sup-
port, without interfering with arm up and down movement.
Tighten knob securely. When the bevel operations are
complete, don't forget to relocate the fence.
NOTE: The guide groove of the fences can become
clogged with sawdust. If you notice that it is becoming
clogged, use a stick or some low pressure air to clear the
guide groove.
AUTOMATIC ELECTRIC BRAKE
Your saw is equipped with an automatic electric blade
brake which stops the saw blade within 5 seconds of trig-
ger release. This is not adjustable.
On occasion, there may be a delay after trigger release to
brake engagement. On rare occasions, the brake may not
engage at all and the blade will coast to a stop.
If a delay or "skipping" occurs, turn the saw on and off 4 or
5 times. If the condition persists, have the tool serviced by
an authorized DEWALT service center.
Always be sure the blade has stopped before removing it
from the kerf. The brake is not a substitute for guards orfor
ensuring your own safety by giving the saw your complete
attention.
GUARD ACTUATION AND VISIBILITY
The blade guard on your saw has been designed to auto-
matically raise when the arm is brought down and to lower
over the blade when the arm is raised.
The guard can be raised by hand when installing or remov-
ing saw blades or for inspection of the saw. NEVER RAISE
THE BLADE GUARD MANUALLY UNLESS THE SAW IS
TURNED OFF.
NOTE: Certain special cuts of large material will require
that you manually raise the guard. See page 12.
The front section of the guard is Iouvered for visibility
while cutting. Although the louvers dramatically reduce
flying debris, they are openings in the guard and safety
glasses should be worn at all times when viewing
through the louvers.
KERF PLATE ADJUSTMENT
To adjust the kerf plates, loosen the screws holding the
kerf plates in place. Adjust so that the kerf plates are as
close as possible without interfering with the blade's move-
ment.
RAIL GUIDE ADJUSTMENT
Periodically check the rails for any play or clearance. The
right rail can be adjusted with the set screw shown in
Figure 4. To reduce clearance, use a 4mm hex wrench and
rotate the set screw clockwise gradually while sliding the

saw head back and forth. Reduce play while maintaining
minimum slide force.
MITER LOCK ADJUSTMENT
The miter lock rod should be adjusted if the table of the
saw can be moved when the miter lock is locked down.
To adjust the miter lock handle, put the miter lock handle
in the up, unlocked position. Using a 13mm open end
wrench, loosen the lock nut on the miter lock rod (Fig.
10). Using a slotted screwdriver, tighten the miter lock
rod by turning it clockwise as shown in Figure 10. Turn
the lock rod until it is snug, then turn counterclockwise
one turn. To ensure the miter lock handle is functioning
properly, re-lock the miter lock to a non-detented meas-
urement on the miter scale - for example, 34 degrees -
and ensure the table will not rotate. Tighten lock nut.
Brushes
DISCONNECT PLUG FROM POWER SUPPLY.
Inspect carbon brushes regularly by unplugging tool,
removing the motor end cap (Fig. 4), lift the brush spring
and withdraw the brush assembly. Keep brushes clean
and sliding freely in their guides. Always replace a used
brush in the same orientation in the holder as it was prior
to its removal. Carbon brushes have varying symbols
stamped into their sides, and if the brush is worn down to
approximately 1/2 inch, the spring will no longer exert pres-
sure and they must be replaced. Use only identical
DEWALT brushes. Use of the correct grade of brush is
essential for proper operation of electric brake. New brush
assemblies are available at DEWALT service centers. The
tool should be allowed to "run in" (run at no load) for 10
minutes before use to seat new brushes. The electric
brake may be erratic in operation until the brushes are
properly seated (worn in). Always replace the brush
inspection cap after inspection or servicing the brushes.
While "running in" DO NOT TIE, TAPE, OR OTHERWISE
LOCK THE TRIGGER SWITCH ON. HOLD BY HAND
ONLY.
on these controls, see the respective sections earlier in the
manual.
MITER CONTROL (FIG. 7)
The miter adjustment/lock handle and detent trigger allows
you to miter your saw to 60 left and 50 right. To miter the
saw, lift the miter adjustment/lock handle, push the miter
latch button and set the set the miter angle desired on the
miter scale. Push down on the lock handle to lock the saw
table in place.
TRIGGER SWITCH
The trigger switch (Fig. 4) turns your saw on and off.A hole
is provided in the trigger for insertion of a padlock to secure
the saw.
MITER LATCH OVERRIDE (FIG. 7)
The miter latch override allows your saw to override the
common stop angles. To override the common stop
angles, push the miter latch button and flip the miter latch
override lever to the vertical position.
BEVEL CONTROL (FIG. 8)
The bevel latch levers and bevel lock handle allow you to
bevel the saw to 48 degrees left and right. Your saw has
two bevel latch levers, one on either side of the rear sup-
port housing. Only one needs to be used to move the bevel
to either direction. The bevel lock handle is on top of the
rear support housing. To bevel the saw, loosen the bevel
lock handle. Lift one of the levers to approximately 45
degrees and set the bevel angle desired on the bevel
scale. Two bevel scales are provided for convenience.
Lock the bevel lock handle to lock the bevel in place. The
bevel latch levers can be lifted vertically to override the
common stop angles.
The bevel lock handle is designed to have a limited rota-
tion amount. The handle can be reoriented to compensate
for normal wear. The bevel lock handle should be reorient-
ed if the bevel of the saw can be moved when the bevel
lock handle is tightened. To adjust the bevel lock handle,
remove the screw in the center of the handle. Carefully pry
off the handle using a flat bladed screwdriver. Reorient and
install the handle such that it will hold the bevel when tight-
ened. Install and tighten screw.
RAIL LOCK KNOB (FIG. 4)
The rail lock knob allows you to lock the saw head firmly to
keep it from sliding on the rails. This is necessary when
making certain cuts or when transporting the saw.
GROOVING STOP (FIG. 4)
The grooving stop allows for groove cutting. Flipping the
lever toward the front of the saw and adjusting the thumb-
screw changes the depth of the groove cut. Flipping the
lever toward the rear of the saw bypasses the grooving
stop.
HEAD DOWNLOCK PIN (FIG. 4)
To lock the saw head in the down position, push the head
down, push the pin in and release the saw head. This will
hold the saw head safely down for moving the saw from
place to place. To release, press the saw head down and
pull the pin out.
Operation
Plug the saw into any household 60 Hz power source.
Refer to the nameplate for voltage. Be sure the cord will
not interfere with your work.
SWITCH
To turn the saw on, depress the trigger switch. To turn the
tool off, release the switch. Allow the blade to spin up to full
operating rpm before making the cut. Release the trigger
switch and allow the brake to stop the blade before raising
the saw head. There is no provision for locking the switch
on, but a hole is provided in the trigger for insertion of a
padlock to lock the saw off.
CUTTING WITH YOUR SAW
If the slide feature is not used, ensure the saw head is
pushed back as far as possible and the rail lock knob is
tightened. This will prevent the saw from sliding along its
rails as the workpiece is engaged.
NOTE: Although this saw will cut wood and many non-
ferrous materials, we will limit our discussion to the cut-
ting of wood only. The same guidelines apply to the
other materials. DO NOT CUT FERROUS (IRON AND
STEEL) MATERIALS OR MASONRY WITH THIS SAW.
Do not use any abrasive blades.
CROSSCUTS
Cutting of multiple pieces is not recommended but can be
done safely by ensuring that each piece is held firmly
against the table and fence. When the saw comes up to
speed (about 1 second) lower the arm smoothly and slow-
ly to cut through the wood. Let the blade come to a full stop
before raising arm.

CAUTION: Always use a work clamp to maintain control
and reduce the risk of workpiece damage and personal
injuoz
NOTE: The rail lock knob shown in Figure 4 must be loose
to allow the saw to slide along its rails.
Miter crosscuts are made with the miter arm at some angle
other than zero. This angle is often 45 degrees for making
corners, but can be set anywhere from zero to 50 degrees
left or right. Make the cut as described above.
When cutting wider workpieces wider than a 2 x 6 that are
shorter in length, always place the longer side against the
fence (Fig. 12).
BEVEL CUTS
A bevel cut is a crosscut made with the saw blade at an
angle to the wood. In order to set the bevel, loosen the
bevel lock handle, lift the bevel latch lever, Figure 4, and
move the sawto the left or right as desired. (It is necessary
to move the fence to allow clearance). Once the desired
bevel angle has been set, tighten the bevel clamp handle
firmly.
Bevel angles can be set from 48 degrees right to
48 degrees left and can be cut with the miter arm set
between 50 degrees right or 60 degrees left. At some
extreme angles, the right or left side fence might have to
be removed. To remove the left or right fence, unscrew
the Fence Adjustment Knob several turns and slide the
fence out.
QUALITY OF CUT
The smoothness ofany cut depends on a number of variables.
Things like material being cut, blade type, blade sharpness
and rate of cut all contribute to the quality ofthe cut.
FIG. 11
FIG. 12
When smoothest cuts are desired for molding and other
precision work, a sharp (60 tooth carbide) blade and a
slower, even cutting rate will produce the desired results.
Ensure that material does not creep while cutting, clamp it
securely in place. Always let the blade come to a full stop
before raising arm.
If small fibers of wood still split out at the rear of the work-
piece, stick a piece of masking tape on the wood where the
cut will be made. Saw through the tape and carefully
remove tape when finished.
For varied cutting applications, refer to the list of recom-
mended saw blades for your saw and select the one that
best fits your needs (page 4).

PROPER CUT
FIG. 13B
IMPROPER CUT
BODY AND HAND POSITION (FIG. 13A)
Proper positioning of your body and hands when operating
the miter saw will make cutting easier, more accurate and
safer. Never place hands near cutting area. Place hands
no closer than 6" from the blade. Hold the workpiece tight-
ly to the table and the fence when cutting. Keep hands in
position until the trigger has been released and the blade
has completely stopped. 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 13B.
Keep both feet firmly on the floor and maintain proper bal-
ance. As you move the miter arm left and right, follow it and
standslightlytothesideofthesawblade.Sightthrough
theguardlouverswhenfollowingapencilline.
CLAMPINGTHEWORKPIECE
Turn Off and Unplug Saw.
If you cannot secure the workpiece on the table and
against the fence by hand, (irregular shape, etc.) or your
hand would be less than 6" from the blade, a clamp or
other fixture must be used.
For best results use the DW7082 clamp made for use with
your saw. Another type of clamp may be supplied with your
DW718. To purchase the DW7082 contact your local retail-
er or DEWALT service center.
Other aids such as spring clamps, bar clamps or C-clamps
may be appropriate for certain sizes and shapes of mate-
rial. Use care in selecting and placing these clamps. Take
time to make a dry run before making the cut. The left or
right fence will slide from side to side to aid in clamping.
TO INSTALL CLAMP
1. Insert it into the hole behind the fence. The clamp
should be facing toward the back of the miter saw. The
groove on the clamp rod should be fully inserted into
the base. Ensure this groove is fully inserted into the
base of the miter saw.
If the groove is visible, the clamp will not be secure.
2. Rotate the clamp 180 degrees toward the front of the
miter saw.
3. Loosen the knob to adjust the clamp up or down, then
use the fine adjust knob to firmly clamp the workpiece.
NOTE: Place the clamp on the opposite side of the base
when beveling. ALWAYS MAKE DRY RUNS (UNPOW-
ERED) BEFORE FINISH CUTS TO CHECK THE PATH
OF THE BLADE. ENSURE THE CLAMP DOES NOT
INTERFERE WITH THE ACTION OF THE SAW OR
GUARDS.
A WARNING: 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 work-
bench. When making a cut that may become unbalanced,
properly support the workpiece and ensure the saw is
firmly bolted to a stable surface.
A WARNING: 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.
SUPPORT FOR LONG PIECES
Turn Off and Unplug Saw.
ALWAYS SUPPORT LONG PIECES.
Never use another person as a substitute for a table
extension; as 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.
FIG. 14 FIG. 15

,.
FIG. 16
For best results, use the DW7080 extension work support
to extend the table width of your saw. Available from your
dealer at extra cost. Support long workpieces using any
convenient means such as sawhorses or similar devices to
keep the ends from dropping.
CUTTING PICTURE FRAMES, SHADOW BOXES AND
OTHER FOUR-SIDED PROJECTS
To best understand how to make the items listed here, we
suggest that you try a few simple projects using scrap
wood until you develop a "FEEL" for your saw.
Your saw is the perfect tool for mitering corners like the one
shown in Figure 14. Sketch A in Figure 15 shows a joint
made by using the bevel adjustment to bevel the edges of
the two boards at 45 degrees each to produce a 90 degree
corner. For this joint the miter arm was locked in the zero
position and the bevel adjustment was locked at 45
degrees. The wood was positioned with the broad flat side
against the table and the narrow edge against the fence.
The cut could also be made by mitering right and left with
the broad surface against the fence.
CUTTING TRIM MOLDING AND OTHER FRAMES
Sketch B in Figure 14 shows a joint made by setting the
miter arm at 45 degrees to miter the two boards to form a
90 degree corner. To make this type of joint, set the bevel
adjustment to zero and the miter arm to 45 degrees. Once
again, position the wood with the broad flat side on the
table and the narrow edge against the fence.
The two sketches in Figure 11 are for four side objects
only.
As the number of sides changes, so do the miter and bevel
angles. The chart below gives the proper angles for a vari-
ety of shapes.
(The chart assumes that all sides are of equal length.) For
a shape that is not shown in the chart, use the following
formula. 180 degrees divided by the number of sides
equals the miter (if the material is cut vertically) or bevel
angle (if the material is cut laying flat).

CUTTING COMPOUND MITERS
A compound miter is a cut made using a miter angle and a
bevel angle at the same time. This is the type of cut used
to make frames or boxes with slanting sides like the one
shown in Figure 16.
NOTE: If the cutting angle varies from cut to cut, check that
the bevel clamp knob and the miter lock knob are secure-
ly tightened. These knobs must be tightened after making
any changes in bevel or miter.
The chart shown on page 14 will assist you inselecting the
proper bevel and miter settings for common compound
miter cuts. To use the chart, select the desired angle "A"
(Figure 16) of your project and locate that angle on the
appropriate arc in the chart. From that point follow the
chart straight down to find the correct bevel angle and
straight across to find the correct miter angle.
Set your saw to the prescribed angles and make a few trial
cuts. Practice fitting the cut pieces together until you devel-
op a feel for this procedure and feel comfortable with it.
Example: To make a 4 sided box with 26 degree exterior
angles (Angle A, Figure 15), use the upper right arc. Find
26° on the arc scale. Follow the horizontal intersecting line
to either side to get miter angle setting on saw (42°).
Likewise, follow the vertical intersecting line to the top or
bottom to get the bevel angle setting on the saw (18°).
Always try cuts on a few scrap pieces of wood to verify
settings on saw.
CUTTING BASE MOLDING
ALWAYS MAKE A DRY RUN WITHOUT POWER
BEFORE MAKING ANY CUTS.
Straight 90 degree cuts:
Position the wood against the fence and hold it in place
as shown in Figure 11.Turn on the saw, allow the blade
to reach full speed and lower the arm smoothly through
the cut.

CUTTING CROWN MOLDING
Your miter saw is better suited to the task of cutting
crown molding than any tool made. In order to fit properly,
crown molding must be compound mitered with extreme
accuracy.
The two flat surfaces on a given piece of crown molding
are at angles that, when added together, equal exactly 90
degrees. Most, but not all, crown molding has a top rear
angle (the section that fits flat against the ceiling) of 52
degrees and a bottom rear angle (the part that fits flat
against the wall) of 38 degrees.
Your miter saw has special pre-set miter latch points at
31.62 degrees left and right for cutting crown molding at the
proper angle and bevel stop pawls at 33.85° left and right.
There is also a mark on the Bevel scale at 33.85 degrees.
The chart below gives the proper settings for cutting crown
molding. (The numbers for the miter and bevel
settings are very precise and are not easy to accurately set
on your saw.) Since most rooms do not have angles of pre-
cisely 90 degrees, you will have to fine tune your settings
anyway.

When setting bevel and miter angles for all compound
miters, remember that:
The angles presented for crown moldings are very
precise and difficult to set exactly. Since they can
easily shift slightly and very few rooms have exact-
ly square corners, all settings should be tested on
scrap molding.

PRETESTING WITH SCRAP MATERIAL IS
ALTERNATIVE METHOD FOR CUTTING
CROWN MOLDING
Place the molding on the table at an angle between the
fence and the saw table, as shown inFigure 18. Use of the
crown molding fence accessory (DW7084) is highly
recommended because of its degree of accuracy and
convenience. The crown molding fence accessory is avail-
able for purchase from your local dealer.
The advantage to cutting crown molding using this method
isthat no bevel cut is required. Minute changes in the miter
angle can be made without affecting the bevel angle. This
way, when corners other than 90 degrees are encountered,
the saw can be quickly and easily adjusted for them. Use
the crown molding fence accessory to maintain the angle
at which the molding will be on the wall.

INSTRUCTIONS FOR CUTTING CROWN MOLDING
ANGLED BETWEEN THE FENCE AND BASE OF THE
SAW FOR ALL CUTS:
1. Angle the molding so the bottom of the molding (part
which goes against the wall when installed) is against
the fence and the top of the molding is resting on the
base of the saw, as shown in Figure 18.
2. The angled '_flats"on the back of the molding must rest
squarely on the fence and base of the saw.

Special Cuts
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS
SECURED ON THE TABLE AND AGAINST THE FENCE.
ALUMINUM CUTTING
ALWAYS USE THE APPROPRIATE SAW BLADE MADE
ESPECIALLY FOR CUTTING ALUMINUM. These are
available at your local DEWALT retailer or DEWALT service
center. Certain workpieces, due to their size, shape or
surface finish, may require the use of a clamp or fixture to
prevent movement during the cut. Position the material so
that you will be cutting the thinnest cross section, as shown
in Figure 19. Figure 20 illustrates the wrong way to cut
these extrusions. Use a stick wax cutting lubricant when
cutting aluminum. Apply the stick wax cutting lubricant
directly to the saw blade before cutting. Never apply stick
wax to a moving blade.
The wax, available at most hardware stores and industrial
mill supply houses, provides proper lubrication and keeps
chips from adhering to the blade.
Be sure to properly secure workpiece. Refer to page 4 for
correct saw blade.
BOWED MATERIAL
When cutting bowed material always position it as shown
in Figure 21 and never like that shown in Figure 22.
Positioning the material incorrectly will cause it to pinch the
blade near the completion of the cut.

CUTTING PLASTIC PIPE OR OTHER
ROUND MATERIAL
Plastic pipe can be easily cut with your saw. It should be
cut just like wood and CLAMPED OR HELD FIRMLY TO
THE FENCE TO KEEP IT FROM ROLLING. This is
extremely important when making angle cuts.
CUTTING LARGE MATERIAL
Occasionally you will encounter a piece of wood a little too
large to fit beneath the blade guard. If this occurs, simply
place your right thumb on the upper side of the guard and
roll the guard up just enough to clear the workpiece, as
shown in Figure 23. Avoid doing this as much as possible,
but if need be, the saw will operate properly and make the
bigger cut. NEVER TIE, TAPE, OR OTHERWISE HOLD
THE GUARD OPEN WHEN OPERATING THIS SAW.
SPECIAL SET-UP FOR WIDE CROSSCUTS
Your saw can cut very wide [up to 16 inch (406mm)] work-
pieces when aspecial set up is used. To set the saw up for
these workpieces, follow these steps:
1. Remove both left and right sliding fences from the saw
and set aside. To remove them, unscrew the fence
knobs several turns and slide each fence outward.
Adjust and lock the miter control so that it is at 0
degrees miter.
2. Make a platform using a piece of 1.5 inch (38mm) thick
particleboard or similar flat strong 1.5 inch thick wood
to the dimensions: 14.5" x 26" (368 x 660mm). The
platform must be flat otherwise the material could
move during cutting and cause injury.
3. Mount the 14.5" x 26" platform to the saw using 4
three-inch long wood screws through the holes in the
base fence (Fig. 24). Four screws must be used to
properly secure the material. When the special set up
is used, the platform will be cut into two pieces. Ensure
the screws are tightened properly otherwise material
could loosen and cause injury. Ensure the platform is
firmly flat on the table, against the fence, and centered
evenly from left to right.
WARNING: Ensure the saw is mounted firmly to a
stable flat surface. Failure to do so could cause the saw
to be unstable and fall causing personal injury.
4. Place the workpiece to be cut on top of the platform
mounted to the table. Ensure the workpiece is firmly
against the backfence (Fig. 25).
5. Secure the material before cutting. Cut slowly through
the material using a out-down-and-back motion.
Failure to clamp securely or cut slowly could result in
the material coming loose and causing injury.
After several cuts are made at various miter angles other
than 0°,the platform may weaken and not properly support
the work. Install a new, unused platform to the saw after
presetting the desired miter angle.
12
CAUTION: Continued use of a platform with several
kerfs may cause loss of material control and possible
injurjz.
Removing and Replacing Belt
The belt is designed to last the life of the tool. However,
abuse of the tool could cause the belt to fail.
If the blade does not turn when the motor is running, the
belt has failed. To inspect or replace the belt, remove the
belt cover screws. Remove the belt cover. Inspect the ribs
of the belt for wear or failure. Check belt tension by squeez-
ing the belt as shown in Figure 26. The belt halves should
almost touch when squeezing firmly with the thumb and
index finger. To adjust the tension, loosen, but do not
remove, the four Phillips head screws shown. Then rotate
the set screw on the top of the motor plate casting until the
proper tension is achieved. Tighten the four screws
securely and replace the belt cover.
NOTE: Over tightening the belt will cause premature motor
failure.
Maintenance
1. All bearings are sealed. They are lubricatedfor life and
need no further maintenance.
2. Periodically clean all dust and wood chips from around
AND UNDER the base and the rotary table. Even
though slots are provided to allow debris to pass
through, some dust will accumulate.
3. The brushes are designed to give you several years
of use. If they ever need replacement follow the
instructions on page 8 or return the tool to the nearest
service center for repair. Service center locations are
packed with your tool.
