4. Depress the spindle lock button (Fig. 3) while carefully

rotating the saw blade by hand until the lock engages.

5. Keeping the button depressed, use the other hand and

the wrench provided (D) to loosen the blade screw.
(Turn clockwise, left-hand threads)

6. Remove the blade screw (E), outer clamp washer (F),

and blade (G). The 1' (25.4mm) blade adapter (H), if
used, and the inner clamp washer (I), may be left on
the spindle.

NOTE: For blades with a blade hole of 5/8' (15.88mm), the
1' (25.4mm) blade adapter is not used.

Installing a Blade

1. Unplug the saw.
2. With the arm raised, the lower guard held open and the

pivot plate raised, place the blade on the spindle, onto
the blade adapter [if using a blade with a 1' (25.4mm)
diameter blade hole] and against the inner clamp
washer with the teeth at the bottom of the blade point-
ing toward the back of the saw.

3. Assemble the outer clamp washer onto the spindle.
4. Install the blade screw and, engaging the spindle lock,

tighten the screw firmly with wrench provided. (Turn
counterclockwise, left-hand threads)

NOTE: When using blades with a 5/8' (15.88mm) diame-
ter blade hole, the blade adapter will not be used and
should be stored in a safe place for future use.

5. Return the guard bracket to its original position and

firmly tighten the guard bracket 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.

WARNING: Do not lift, support, or carry the miter saw

by the extension kit. To do so may cause tipping and loss
of control, leading to personal injury.

NOTE: Before transporting the saw, remove the extension
or telescope it into the base.

Rear Lower Guard Adjustment

Check the rear lower guard to ensure that it is located such
that the saw blade is in the center and equidistant from
each side, as shown in Figures 6 and 7. Adjust as neces-
sary by loosening the two screws and moving the guard.
Firmly tighten both screws. Never remove this guard.

Transporting the Saw

TURN OFF AND UNPLUG THE MITER SAW BEFORE
ATTEMPTING TO MOVE IT OR MAKE ANY ADJUST-
MENTS 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, as shown in Figure 3. To transport the saw,
lower the arm and depress the lock down pin shown in
Figure 4.

Adjustments

PERFORM ALL ADJUSTMENTS WITH THE MITER
SAW UNPLUGGED
NOTE: 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 steps 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
Place a square against the saw’s fence and blade, as
shown in Figure 8. (Do not touch the tips of the blade teeth
with the square. To do so will cause an inaccurate meas-
urement.) Loosen the miter clamp knob (see Fig. 9) and
swing the miter arm until the miter latch locks it at the 0
miter position. Do not tighten the clamp knob. If the saw
blade is not exactly perpendicular to the fence, loosen the
three screws that hold the miter scale to the base (shown
in Fig. 9) and move the scale/miter arm assembly left or
right until the blade is perpendicular to the fence, as meas-
ured with the square. Retighten the three screws. Pay no
attention to the reading of the miter pointer at this point.

MITER POINTER ADJUSTMENT
Loosen the miter clamp knob and squeeze the miter latch
to move the miter arm to the zero position, as shown in
Figure 9. With the miter clamp knob loose allow the miter
latch to snap into place as you rotate the miter arm past
zero. Observe the pointer and miter scale through the
viewing opening shown in Figure 10. If the pointer does
not indicate exactly zero, gently pry it left or right using a
flat bladed screwdriver.

Bevel angles can be set from 3 degrees right to
48 degrees left and can be cut with the miter arm set
between zero and 48 degrees right or left.

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) 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 3).

BODY AND HAND POSITION (FIG. 16)
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 16.
Keep both feet firmly on the floor and maintain proper bal-
ance. 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
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 should be used.
For best results us the DW7052 clamp made for use with
your saw. It is available through your local retailer or
D

WALT service center at extra cost.

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
fence will slide from side to side to aid in clamping.

SUPPORT FOR LONG PIECES
Turn Off and Unplug Saw
ALWAYS SUPPORT LONG PIECES
For best results, use the DW7050 extension work support
to extend the table width of your saw. Available from your
