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 49º right to 49º left and can be
cut with the miter arm set between 50º left or 60º 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) 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.
If small 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 Optional Accessories.
BODY AND HAND POSITION (FIG. 9A, 9B)
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 9B.
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 it 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" of the blade
during the cut.

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" (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 D
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 180º 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
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.
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, 10)
Lock the arm in the down position. Unlock the miter lock
handle and swing the miter arm until the miter latch button
locks it at the 0° miter position. Do not lock the miter lock
handle. 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 measure ment.)
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 handle 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.
