Miter Scale; Vernier Scale; When Mitering To The Right; When Mitering To The Left - DeWalt DW713 Instruction Manual

The chart (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" (Figure 19) 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, Figure 19), 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 settings on saw.
MITER SCALE (FIG. 20)
The scale is used when calculating angles. To calculate the
proper miter angle, divide 180° by the number of sides of the
box or frame. Refer to the chart for some examples.
VERNIER SCALE (FIG. 22, 23)
Your saw is equipped with a vernier scale for added
precision. The vernier scale allows you to accurately set
miter angles to the nearest 1/4°. To use the vernier scale
follow the steps listed below.
(As an example, let's assume that the angle you want to
miter is 24-1/4° right).
1. Turn off miter saw.
2. Set the miter angle to the nearest whole degree desired
by aligning the center mark in the vernier scale, shown
in Figure 22, with the whole degree number etched in
the miter scale. Examine Figure 22 closely; the setting
shown is 24º right miter.
3. To set the additional 1/4°, squeeze the miter arm lock
and carefully move the arm to the RIGHT until the 1/4°
vernier mark aligns with the CLOSEST degree mark on
the miter scale. In our example, the closest degree mark
on the miter scale happens to be 25°. Figure 23 shows
a setting of 24-1/4° right miter.
For settings that require partial degrees (1/4, 1/2, 3/4°) align
the desired vernier mark with the CLOSEST degree mark
on the miter scale, as described above. (The plastic vernier
plate is inscribed with marks for 1/4, 1/2, 3/4 and 1°. Only
the 1/2° is numerically labeled.)

WHEN MITERING TO THE RIGHT

To increase the miter angle when mitering to the right, move
the arm to align the appropriate vernier mark with the closest
mark on the miter scale to the right. To decrease the miter
angle when mitering to the right, move the arm to align the
appropriate vernier mark with the closest mark on the miter
scale to the left.

WHEN MITERING TO THE LEFT

To increase the miter angle when mitering to the left, move
the arm to align the appropriate vernier mark with the closest
mark on the miter scale to the left. To decrease the miter
angle when mitering to the left, move the arm to align the
appropriate vernier mark with the closest mark on the miter
scale to the right.

CUTTING BASE MOLDING

ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE
MAKING ANY CUTS.
Straight 90° cuts :
Position the wood against the fence as shown in
Figure 21. Turn on the saw, allow the blade to reach full
speed and lower the arm smoothly through the cut.
CUTTING BASE MOLDING UP TO 3.5" (88.9 mm)
HIGH VERTICALLY AGAINST THE FENCE
Position molding as shown in Figure 21.
All cuts are made with the back of the molding against the
fence and bottom of the molding against the base.

Material up to 3.5" (88.9 mm) can be cut as described
above. For wider boards [up to 4.25" (107.95 mm)] several
minor concessions must be made.
When cutting a board between 3.5" (88.9 mm) and 4.25"
(107.95 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 24. Once you have cleared the workpiece, you can
release the guard and it will continue to open as the cut
progresses.
When mitering to the right side of a base molding wider
than 3.5" (88.9 mm) standing vertically against the fence as
in Figure 21, 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 3-1/2"
(88.9 mm) and 4.25" (107.95 mm) wide vertically follow the
directions below.
