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 sliding fence
To Install Clamp (Fig. A)
1. Insert the clamp
21
into one of the four locations
2. Lifting up on the arm of the clamp can rapidly adjust the height, 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.
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.
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
WARNING: To reduce the risk of serious personal injury, turn off the tool and
disconnect it from the power source before attempting to move it, change
accessories or make any adjustments.
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 mitre saw table or to help feed, support or pull
the workpiece.
For best results, use the DWX723, DWX724, DWX725B or DWX726 mitre saw stand to extend the
table width of your saw. These are 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. P)
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 mitring corners like the one shown in Figure P. Sketch A in
Figure P shows a joint made by using the bevel adjustment to bevel the edges of the two boards
at 45° each to produce a 90° mitre corner. For this joint the mitre 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
mitring right and left with the broad surface against the fence.
Cutting Trim Molding and Other Frames (Fig. P)
Sketch B in Figure P shows a joint made by setting the mitre arm at 45° to mitre the two boards
to form a 90° corner. To make this type of joint, set the bevel adjustment to zero and the mitre
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 P are for four sided objects only.
As the number of sides changes, so do the mitre and bevel angles. The chart below gives the
proper angles for a variety 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° divided by the number of
sides equals the mitre or bevel angle.

Cutting Compound Mitres (Fig. Q, R)
A compound mitre is a cut made using a mitre 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 Q.
nOTE: If the cutting angle varies from cut to cut, check that the bevel clamp knob and the mitre
lock knob are securely tightened. These knobs must be tightened after making any changes in
bevel or mitre.
The chart (Table 1) will assist you in selecting the proper bevel and mitre settings for common
compound mitre cuts. To use the chart, select the desired angle "A" (Figure R) 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 mitre 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, Figure R), use the upper right
arc. Find 26° on the arc scale. Follow the horizontal intersecting line to either side to get mitre
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.
Fig. Q
When Mitring to the Right
To increase the mitre angle when mitring to the right, move the arm to align the appropriate
vernier mark with the closest mark on the mitre scale to the right. To decrease the mitre angle
when mitring to the right, move the arm to align the appropriate vernier mark with the closest
mark on the mitre scale to the left.
When Mitring to the Left
To increase the mitre angle when mitring to the left, move the arm to align the appropriate
vernier mark with the closest mark on the mitre scale to the left. To decrease the mitre angle
when mitring to the left, move the arm to align the appropriate vernier mark with the closest
mark on the mitre scale to the right.
Cutting Base Molding (Fig. S)
ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS.
Straight 90° cuts:
Position the wood against the fence and hold it in place as shown in Figure S. Turn on the saw,
allow the blade to reach full speed and lower the arm smoothly through the cut.
