FOR FUTURE REFERENCE

Double Insulation

Double insulated tools are constructed throughout with two separate layers of electrical
insulation or one single layer of reinforced insulation between you and the tool's electrical
system. 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 without
concern for maintaining a ground connection.
NOTE: Double insulation does not take the place of normal safety precautions when
operating this tool. The secondary insulation system is for protection against injury resulting
from a possible failure of the primary insulation within the tool.
_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

AWARNING: To reduce the risk of eye injury, ALWAYS use eye protection when

operating the miter saw.

• 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. Tools,scrap
pieces, and other debris can be thrown at high speed, causing injury,

• KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.

• DO NOT USE THE MACHINE IN A DANGEROUS ENVIRONMENT. The use of power
tools in damp or wet locations or in rain can cause shock or electrocution. Keep your work
area well-lit to avoid tripping or placing arms, hands, and fingers in danger.

• KEEP CHILDREN AWAY. All visitors should be kept at a safe distance from work area.
Your shop is a potentially dangerous environment.

• MAKE WORKSHOP CHILDPROOF with padlocks, master switches, or by removing
starter keys. The unauthorized start-up of a machine by a child or visitor may result in injury,

• DON'T FORCE 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. Using the incorrect tool or attachment may result in personal injury,

• WEAR PROPER APPAREL. Do not wear loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get caught in moving parts. Nonslip footwear is
recommended. Wear protective hair covering to contain long hair.

• ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety glasses. Also
use face or dust mask if cutting operation is dusty, ALWAYS WEAR CERTIFIED SAFETY

EQUIPMENT."

• ANSI Z87.1 eye protection (CAN/CSA Z94.3).

• ANSI $12.6 ($3.19) hearing protection.

• NIOSH/OSHA/MSHA respiratory protection.

• SECURE THE WORKPIECE. Use clamps or a vise to hold the workpiece on the table
and against the fence or when your hand will be dangerously close to the blade within 6"
(152 mm). It is safer than using your hand and it frees both hands to operate tool

• DON'T OVERREACH. Keep proper footing and balance at all times. Loss of balance may
cause personal injury,

• MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and safest

performance. Follow instructions for lubricating and changing accessories. Poorly

maintained tools and machines can further damage the tool or machine and/or cause

Additional Safety Rules For Miter Saws

WARNING: Do not allow familiarity (gained from frequent use of your saw) to replace safety

rules.Always remember that a careless fraction of a second is sufficient to inflict severe injury.

• DO NOT OPERATE THIS MACHINE until it is completely assembled and installed

according to the instructions. A machine incorrectly assembled can cause serious injury.

• OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are

not thoroughly familiar with the operation of this machine. Knowledge is safety.

• STABILITY. Make sure the miter saw is placed on a secure supporting surface and does

not slip or move during use.

• FOLLOW ALL WIRING CODES and recommended electrical connections to prevent

shock or electrocution. Protect electric supply line with at least a 15 ampere time-delay

fuse or a circuit breaker.

• MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should

point in the direction of rotation as marked on the saw.

• TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation. Loose clamps
can cause parts or the workpiece to be thrown at high speeds.

• BE SURE all blade and blade clamps are clean, recessed sides of blade clamps are

against blade and arbor screw is tightened securely. Loose or improper blade clamping
may result in damage to the saw and possible personal injury.

• ALWAYS USE A SHARP BLADE. Check the blade to see if it runs true and is free from
vibration. A dull or a vibrating blade can cause damage to the machine and/or serious

injury.

• DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED VOLTAGE for
the saw. Overheating, damage to the tool and personal injury may occur.

• DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to
tool and possible personal injury may occur.

• DO NOT FORCE CUTTING ACTION. Stalling or partial stalling of motor can cause
damage to the machine or blade and/or serious injury.

• ALLOW THE MOTOR TO COME TO FULL SPEED priorto starting cut. Starting the cut
too soon may cause damage to the machine or blade and/or serious injury.

• NEVER CUT FERROUS METALS (those with any iron or steel content) or masonry.
Either of these can cause the carbide tips to flyoff the blade at high speeds causing serious
injury.

• DO NOTUSEABRASIVE WHEELS. The excessive heat and abrasive particles generated
by them may damage the saw and cause personal injury.

• NEVER HAVE ANY PART OF YOUR BODY IN LINE WITH THE PATH OF THE SAW
BLADE. Personal injury will occur.

• NEVER APPLY BLADE LUBRICANT TO A RUNNING BLADE. Applying lubricant could
cause your hand to move into the blade resulting in serious injury.

• DO NOT place either hand in the blade area when the saw is connected to the power
source. Inadvertent blade activation may result in serious injury.

• DO NOT PERFORM FREEHAND OPERATIONS (workpiece not supported by table and
fence). Hold the work firmly against the fence and table. Freehand operations on a miter
saw could cause the workpiece to be thrown at high speeds, causing serious injury.

• NEVER REACH AROUND OR BEHIND THE SAW BLADE. A blade can cause serious
injury.

• DO NOT REACH UNDERNEATH THE SAW unless it is unplugged and turned off.
Contact with saw blade may cause personal injury.

• SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. Vibration can

possibly cause the machine to slide, walk, or tip over, causing serious injury.

• USE ONLY CROSSCUT SAW BLADES recommended for miter saws. For best results,
do not use carbide tipped blades with hook angles in excess of 7 degrees. Do not use
blades with deep gullets. These can deflect and contact the guard, and can cause damage
to the machine and/or serious injury.

• USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this tool to

prevent damage to the machine and/or serious injury.

• INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or
damaged blade can come apart and pieces can be thrown at high speeds, causing serious
injury. Replace cracked or damaged blades immediately.

• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning the blade
and blade clamps allows you to check for any damage to the blade or blade clamps. A
cracked or damaged blade or blade clamp can come apart and pieces can be thrown at
high speeds, causing serious injury.

• DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the

plastic guard. The polycarbonate material used in the guard is subject to attack by certain

chemicals.

• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED.
Small chip accumulation under the saw may interfere with the saw blade or may cause
instability of workpiece when cutting.

• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to prevent damage to the
machine and/or serious injury.

• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can
cause the machine to overheat, damaging the machine and possibly causing a short which
could cause serious injury.

• KEEP ARMS, HANDS, AND FINGERS AWAY FROM THE BLADE to prevent severe
cuts. Clamp all workpieces that would cause your hand to be within 6" (152 mm) of the

saw blade.

• NEVER LOCK THE SWITCH IN THE "ON" POSITION. Severe personal injury may
result.

• TURN OFF THE MACHINE and allow the blade to come to a complete stop before
raising the arm and prior to cleaning the blade area, removing debris in the path of the
blade, before servicing or adjusting tool A moving blade can cause serious injury.

• PROPERLY SUPPORT LONG OR WIDE WORKPIECES. Loss of control of the
workpiece can cause injury.

• NEVER CROSS ARMS IN FRONT OF BLADE while using tool Always make a dry run
(unpowered) before making a finish cut so that you can check the path of the blade or

severe personal injury may result.

Familiarization FIG.2

Your miter saw is fully assembled in the carton.
Open the box and lift the saw out by the
hand indentations in the base of the saw, as
shown in Figure 2.
Place the saw on a smooth, flat surface such as
a workbench or strong table.
Examine Figure 4 to become familiar with the
saw and its various parts. The section on adjus-
tments will refer to these terms and you must
know what and where the parts are.
i_CAUTION: Pinch hazard. To reduce the risk

of injury, keep thumb underneath the operating
handle when pulling the handle down. The lower

guard will move up as the operating handle is
pulled down, which could cause pinching. The

operating handle is placed close to the guard for
special cuts.

Press down lightly on the operating handle and pull out the lock down pin. Gently release the
downward pressure and hold the operating handle, 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 hand
indentations to transport the saw as seen in Figure 4.

Bench Mounting

Holes are provided in all 4 feet to facilitate bench mounting, 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" (12.7 mm)
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 plywood, 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 surface, clamp only on the clamping bosses
where the mounting screw holes are located. Clamping at any other point will interfere with
the proper operation of the saw.
i_CAUTION: Toprevent 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 material under one
saw foot until the saw sits firmly on the mounting surface.

LOCK DOWN PIN (FIG. 4}

i_WARNING: The lock down pin should be used ONLY
when carrying or storing the saw. NEVER use the lock down

pin for any cutting operation.

To lock the saw head in the down position, push the saw
head down, push the lock down 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.

AUTOMATIC ELECTRIC BRAKE

Your saw is equipped with an automatic electric blade
brake which stops the saw blade within 5 seconds of trigger
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.
Ifa 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 or for
ensuring your own safety by giving the saw your complete
attention.

OPERATION

i_ WARNING: 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.

J_WARNING: Always use eye protection. All users and
bystanders must wear eye protection that conforms to ANSI

Z87.1 (CAN/CSA Z94.3).

h_WARNING: 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.

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.

Trigger Switch (Fig. 4)

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 speed 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 detailed discussion to the
cutting 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.

NOTE: Refer to Guard Actuation and Visibility in the

Adjustments section for important information about the

lower guard before cutting.

CROSSCUTS

A crosscut is made by cutting wood across the grain at any
angle. A straight crosscut is made with the miter arm at the
zero degree position. Set and lock the miter arm at zero, hold

the wood firmly on the table and against the fence. With the rail lock knob tightened, turn on
the saw by squeezing the trigger switch shown in Figure 4.
When the saw comes up to speed (about 1 second) lower the arm smoothly and slowly to cut
through the wood. Let the blade come to a full stop before raising arm.
When cutting anything larger than a 2 x 8 (51 x 203 mm [2 x 6 (51 x 152) at 45° miter]) use an
out-down-back motion with the rail lock knob loosened. Pull the saw out, toward you, lower
the saw head down toward the workpiece, and slowly push the saw back to complete the
cut. Do not allow the saw to contact the top of the workpiece while pulling out. The saw may
run toward you, possibly causing personal injury or damage to the workpiece.
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.

NOTE; To provide greater crosscut capacity with reduced stroke, the blade on the DWS709
extends deeper into the table. As a result, a greater lifting force on the workpiece may be
experienced during the cut.

A WARNING: Always use a work clamp to maintain control and reduce the risk of workpiece

damage and personal injury,if your hands are required to be within 6" (152 mm) of the blade
during the cut.

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° for making corners, but can be set anywhere from zero to 50° left or 60° right. Make the
cut as described above.

When performing a miter cut on workpieces wider than a 2 x 6 that are shorter in length,
always place the longer side against the fence (Fig. 7).

To cut through an existing pencil line on a piece of wood, match the angle as close as
possible. Cut the wood a little too long and measure from the pencil line to the cut edge to
determine which direction to adjust the miter angle and recut. This will take some practice,
but it is a commonly used technique.

BEVEL CUTS

A bevel cut is a crosscut made with the saw blade leaning at an angle to the wood. In order to
set the bevel, loosen the bevel lock (Fig. 4), and move the saw to 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 lock firmly. Refer to the Features and Controls section for detailed
instructions on the bevel system.

Bevel angles can be set from 49° right to 49 ° left and can be cut with the miter arm set
between 50° left or 60° right. 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.

NOTE: Refer to Fence Adjustment in the Adjustments section for important information on
adjusting the fences for certain bevel cuts.

QUALITY OF CUT

The smoothness of any 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 of the cut.
When smoothest cuts are desired for molding and other precision work, a sharp (60 tooth
carbide tip or greater) blade and a slower, even cutting rate will produce the desired results.

Ensure that the material does not move or creep while cutting; clamp it securely in place.
Always let the blade come to a full stop before raising arm.

Ifsmall fibers of wood still split out at the rear of the workpiece, 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 recommended saw blades for your saw and
select the one that best fits your needs. Refer to Saw Blades under OptionalAccessories.

BODY AND HAND POSITION (FIG. 8A-8D)

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" (152 mm) from the blade. Hold the workpiece tightly 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 8C.

Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm
left and right, follow it and stand slightly to the side of the saw blade. Sight through the guard
louvers when following a pencil line.

CLAMPING THE WORKPIECE

_ WARNING: To reduce the risk of injury, turn unit off

and disconnect ff from power source before installing
and removing accessories, before adjusting or when
making repairs. An accidental start-up can cause injury.

_,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 workbench.

When making a cut that may become unbalanced, properly
support the workpiece and ensure the saw is firmly bolted to
a stable surface. Personal injury may occur.

_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.

_ CAUTION: Always use a work clamp to maintain control
and reduce the risk of workpiece damage and personal
injury,if your hands are required to be within 6" (152 mm) of
the blade during the cut.

FIG. 8B

PROPER CUT

FIG.8D

IMPROPER CUT

Ifyou cannot secure the workpiece on the table and against
the fence by hand (irregular shape, etc.), or your hand would
be less than 6" (152 mm) from the blade, a clamp or other

fixture must be used.
Use the material clamp provided with your saw. To purchase

the material clamp, contact your local retailer or DEWALT
service center.

Other aids such as spring clamps, bar clamps or C-clamps
may be appropriate for certain sizes and shapes of material.
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° 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 (UNPOWERED)

BEFORE FINISH CUTS TO CHECK THE PATH OF THE
BLADE. ENSURE THE CLAMP DOES NOT INTERFERE
WITH THE ACTION OF THE SAW OR GUARDS.

ADJUSTMENTS

A WARNING: To reduce the risk of injury, turn unit off
and disconnect ff from power source before installing
and removing accessories, before adjusting or when
making repairs. An accidental start-up can cause injury.

Your miter saw is fully and accurately adjusted at the factory
at the time of manufacture. If readjustment due to shipping
and handling or any other reason is required, follow the
instructions below to adjust your saw.

Once made, these adjustments should remain accurate.
Take a little time now to follow these directions carefully to
maintain the accuracy of which your saw is capable.

MITER SCALE ADJUSTMENT (FIG. 5, 9)

Lock the arm in the down position. Unlock the miter lock
knob and swing the miter arm until the miter latch button
locks it at the 0° miter position. Do not lock the miter lock
knob. Place a square against the saw's fence and blade, as
shown. (Do not touch the tips of the blade teeth with the
square. To do so will cause an inaccurate measurement.)
If the saw blade is not exactly perpendicular to the fence,

loosen the four- screws that hold the miter scale and move
the miter lock knob and the scale left or right until the blade

is perpendicular to the fence, as measured with the square.
Retighten the four screws. Pay no attention to the reading of
the miter pointer at this time.

FIG. 9

MITER LOCK

KNOB

MITER POINTER ADJUSTMENT (FIG. 5)

Unlock the miter lock knob to move the miter arm to the zero
position. With the miter lock knob unlocked, allow the miter
latch to snap into place as you rotate the miter arm to zero.
Observe the miter pointer and miter scale shown in Figure 5.
Ifthe pointer does not indicate exactly zero, loosen the miter
pointer screw holding the pointer in place, reposition the
pointer and tighten the screw.

BEVEL SQUARE TO TABLE ADJUSTMENT
(FIG. 4, 6, 10)

Toalign the blade square to the table, lock the arm in the down position with the lock down
pin. Place a square against the blade, ensuring the square is not on top of a tooth. Loosen
the bevel lock knob and ensure the arm is firmly against the 0° bevel stop. Rotate the 0° bevel
adjustment screw with the 1/2" (13 mm) blade wrench as necessary so that the blade is at 0°
bevel to the table, as measured with the square.

FIG. 10

MITER LOCK

KNOB

BEVEL POINTERS (FIG. 6)

If the bevel pointers do not indicate zero, loosen each screw that holds each bevel pointer in
place and move them as necessary. Ensure the 0° bevel is correct and the bevel pointers are
set before adjusting any other bevel angle screws.

BEVEL STOP 45° RIGHT AND LEFT ADJUSTMENT (FIG. 4, 6}
Toadjust the right 45 ° bevel angle, loosen the bevel lock knob and pull the 0° bevel stop to
override the 0° bevel stop. When the saw is fully to the right, if the bevel pointer does not
indicate exactly 45°, turn the left 45 ° bevel adjustment screw with the 1/2" (13 mm) blade
wrench until the bevel pointer indicates 45°.
Toadjust the left 45 ° bevel stop, first loosen the bevel lock knob and tilt the head to the left.
If the bevel pointer does not indicate exactly 45 °, turn the right 45 ° bevel adjustment screw
until the bevel pointer reads 45 °.

FENCE ADJUSTMENT (FIG. 4)

In order that the saw can bevel to many bevel positions, one of the fences may have to be
adjusted to provide clearance. To adjust each fence, loosen the fence adjustment 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
support, without interfering with arm up and down movement. Tighten the fence adjustment
knob securely. When the bevel operations are complete, don't forget to relocate the fence.
For certain cuts, it may be desirable to bring the fences closer to the blade. To use this feature,
back the fence adjustment knobs out two turns and move the fences closer to the blade past
the normal limit, then tighten the fence adjustment knobs to keep the fences in this location.
When using this feature, make a dry cut first to ensure the blade does not contact the fences.
NOTE: The tracks of the fences can become clogged with sawdust. If you notice that they are
becoming clogged, use a brush or some low pressure air to clear the guide grooves.

GUARD ACTUATION AND VISIBILITY (FIG. 4)

_CAUTION: Pinch hazard. To reduce the risk of injury,keep thumb underneath the operating
handle when pulling the handle down. The lower guard will move up as the operating handle
is pulled down, which could cause pinching.

The lower guard on your saw has been designed to automatically uncover the blade when the
arm is brought down and to cover the blade when the arm is raised.
The guard can be raised by hand when installing or removing saw blades or for inspection
of the saw. NEVER RAISE THE LOWER GUARD MANUALLY UNLESS THE BLADE IS
STOPPED.

NOTE: Certain special cuts of large material will require that you manually raise the guard.

Refer to Cutting Large Material under Special Cuts.
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.

KERF PLATE ADJUSTMENT (FIG. 4)

To adjust the kerf plate, loosen the screws holding the kerf plate in place. Adjust so that the
kerf plate does not interfere with the blade's movement.

RAIL GUIDE ADJUSTMENT (FIG. 4)

Periodically check the rails for any debris, play or clearance. The rails can be cleaned with a
dry clean cloth. The right rail can be adjusted with the set screw shown in Figure 4. To reduce
clearance, use a 4 mm hex wrench and rotate the set screw clockwise gradually while sliding
the saw head back and forth. Reduce play while maintaining minimum slide force.

Support for Long Pieces

_ WARNING: 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.

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.

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 (Fig. 11, 12)

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 11. Sketch A in

Figure 12 shows a joint made by using the bevel adjustment to bevel the edges of the two
boards at 45° each to produce a 90° corner. For this joint the miter arm was locked in the
zero position and the bevel adjustment was locked at 45°.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.

FIG. 11 FIG. 12

10

Cutting Trim Molding And Other Frames (Fig. 12)

Sketch B in Figure 12 shows a joint made by setting the miter arm at 45° to miter the two
boards to form a 90° corner. To make this type of joint, set the bevel adjustment to zero and
the miter arm to 45 °. 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 12 are for four-sided objects only.
As the number of sides changes, so do the miter and bevel angles. The chart below gives the

proper angles for a variety of shapes.

Material up to 6.75" (171 mm) can be cut as described above.

FIG. 14

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° 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 FIG.13
(Fig. 13)

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 13.
NOTE: If the cutting angle varies from cut to cut,
check that the bevel lock knob and the miter lock
knob are securely locked. These must be locked
after making any changes in bevel or miter.
The chart at the end of this manual (Table 1) will assist you in selecting the proper bevel and
miter settings for common compound miter cuts. To use the chart, select the desired angle A
(Fig. 13) 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 develop a feel for this procedure and feel comfortable with it.
Example: To make a 4-sided box with 26° exterior angles (Angle A, Fig. 13), 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 the settings on the saw.

Cutting Base Molding (Fig. 14)

Straight 90° cuts:

Position the wood against the fence and hold it in place as shown in Figure 14. Turn on
the saw, allow the blade to reach full speed and lower the arm smoothly through the cut.

CUTTING BASE MOLDING UP TO 4.5" (114 ram) HIGH VERTICALLY AGAINST THE
FENCE

Position material as shown in Figure 14.

ANGLE "A"

Cutting Crown Molding

Your miter saw is well suited to the task of cutting crown molding. 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°. Most, but not all, crown molding has a top rear angle (the section
that fits flat against the ceiling) of 52° and a bottom rear angle (the part that fits flat against
the wall) of 38°.
Your miter saw has special pre-set miter latch points at 31.62 ° left and right for cutting crown
molding at the proper angle and bevel stop pawls at 33.9° left and right. There is also a mark
on the bevel scale at 33.9 °.

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 precisely 90°, you will have to fine tune your
settings anyway.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

INSTRUCTIONS FOR cu'rI'ING CROWN MOLDING LAYING FLAT AND USING THE
COMPOUND FEATURES

1. Molding should lay flat with broad back surface down on saw table (Fig. 15).

2. Top of molding against fence.

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 exactly square corners, all
settings should be tested on scrap molding.

PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!

ALTERNATIVE METHOD FOR CUTTING CROWN MOLDING

Place the molding on the table at an angle between the fence and the saw table, as shown
in Figure 16. Use of the crown molding fence accessory (DW7084) is highly recommended
because of its degree of accuracy and convenience (Fig. 1). The crown molding fence
accessory is available for purchase from your local dealer.

The advantage to cutting crown molding using this method is that 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° 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 saw table, as
shown in Figure 16.

2. The angled "flats" on the back of the molding must rest squarely on the fence and saw
table.

NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND

AGAINST THE FENCE.

ALUMINUM CUTTING (FIG. 17, 18)

ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING
ALUMINUM. These are available at your local DEWALT retailer or DRWALT 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 17. Figure 18 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 Saw Blades under Optional Accessories for correct saw blade.

BOWED MATERIAL (FIG. 19, 20)

When cutting bowed material always position it as shown in Figure 19 and never like that
shown in Figure 20. Positioning the material incorrectly will cause it to pinch the blade near
the completion of the cut.

cu'rI'ING 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.
cu'rI'ING LARGE MATERIAL (FIG. 21)

Occasionally you will encounter a piece of wood a little too large to fit beneath the lower
guard. To clear the guard over the wood, with the motor off and your right hand on the
operating handle, place your right thumb outside of the upper portion of the guard and roll
the guard up just enough to clear the wood, as shown in Figure 21. Release the guard prior
to starting the motor. The guard mechanism will function properly during the cut. Only do
this when necessary. NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN
OPERATING THIS SAW.

SPECIAL SET-UP FOR WIDE CROSSCUTS (FIG. 22, 23)

Your saw can cut very wide (up to 13-3/8" [340 mm]) workpieces when a special 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 adjustment knobs several turns and slide each fence outward. Adjust

and lock the miter control so that it is at 0° miter.

2. Make a platform using a piece of 1.5" (38 mm) thick particleboard or similar flat strong

1.5" thick wood to the dimensions: 12" x 24" (305 x 610 mm). The platform must be flat,

otherwise the material could move during cutting and cause injury.

3. Mount the 12" x 24" (305 x 610 mm) platform to the saw using four 3" (76.2 mm) long
wood screws through the holes in the base fence (Fig. 22). 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.

i_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 back of the base fence (Fig. 23).

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.

_CAUTION: Continued use of a

platform with several kerfs may cause

loss of material control and possible
injury.

Removing and Replacing Belt (Fig. 4, 24)

The belt is designed to last the life of the FIG.24
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 squeezing the belt as
shown in Figure 24. 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 crosshead 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.

NOTICE: Overtightening the belt will cause premature motor failure.

Dust Duct Cleaning

Depending on your cutting environment, saw dust can clog the dust duct and may prevent
dust from flowing away from the cutting area properly. With the saw unplugged and the saw
head raised fully, low pressure air or a large diameter dowel rod can be used to clear the dust
out of the dust duct.

Brushes

_ WARNING: 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.

Inspect carbon brushes regularly by unplugging tool, removing the motor endcap (Fig. 4),

lifting the brush spring and withdrawing 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. If the brushes are worn down to approximately 1/2" (12.7 mm), the

springs will no longer exert pressure 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.

Cleaning

A WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week.

To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye protection when
performing this.

i_,WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts

of the tool. These chemicals may weaken the plastic materials used in these parts. Use a

cloth dampened only with water and mild soap. Never let any liquid get inside the tool,"never
immerse any part of the tool into a liquid.
