For best results, use the DWX723, DE7260 or DE7033 mitre saw stand to extend the table
width of your saw. This is 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 mitreing 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 mitreing 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.

is used when calculating angles. To calculate the proper mitre angle, divide
180° by the number of sides of the box or frame. Refer toExamples.
When Mitreing to the Right
To increase the mitre angle when mitreing 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 mitreing to the right, move the arm to align the appropriate vernier mark with the
closest mark on the mitre scale to theleft.
When Mitreing to the Left
To increase the mitre angle when mitreing 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 mitreing 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
ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANYCUTS.
Straight 90° Cuts (Fig. S)
Position the wood against the fence as shown in FigureS. Turn on the saw, allow the blade to
reach full speed and lower the arm smoothly through thecut.
Cutting Base Molding up to 89 mm High Vertically Against The Fence
(Fig. L, S)
Position molding as shown in FigureS.
All cuts are made with the back of the molding against the fence and bottom of the molding
against thebase.

Material up to 89 mm can be cut as described above. For wider boards [up to 108 mm] several
minor concessions must bemade.
When cutting a board between 89 mm and 108 mm in width the roller on the tip of the
guard could hang up on the workpiece. 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L. Once you have cleared the workpiece, you can release the guard and it will continue
to open as the cutprogresses.
When mitreing to the right side of a base molding wider than 89 mm standing vertically
against the fence as in FigureU, the saw can only cut through the board up to 1 inch from the
end of the board. Trying to cut more than an inch will cause the saw’s gear case to interfere
with the workpiece. If you want to cut base molding between 89 mm and 108 mm wide
vertically follow the directionsbelow.

* NOTE: If the cut must be made somewhere other than 1" from the end of the molding: cut off
the molding at 90° approx. 25.4 mm longer than your final length then make the mitre cut as
described above.
Another method of making the cut is to make a zero degree mitre, 45° bevel cut. Your saw can
cut a bevel 158 mmwide.
Cutting Base Molding Laying Flat and Using the Bevel Feature
• All cuts made with the saw set at 45° bevel and 0mitre.
• All cuts made with back of molding laying flat on thesaw.
• Move the left side fence out of the path of the blade before attempting any of the
followingcuts.
