Cutting Base Molding - DeWalt DW708 Instruction Manual

miter 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. Alternatively, the cut could also be made by
mitering right and left with the broad surface against the fence
and the narrow edge against the table.

CUTTING TRIM MOLDING AND OTHER FRAMES
Sketch B shows a joint made by setting the miter adjustment
at 45˚. The wood is positioned with the broad flat side on the
table and the narrow edge against the fence. Mitering the
boards forms a 90˚ corner.
The two sketches in figure 17 are for four sided objects only.
As the number of sides changes, so do the miter and bevel
angles. The following chart 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
miter or bevel angle.

DUAL RANGE MITER SCALE
The 0˚ scale (larger numbers closest to the front edge of the
miter guide) is designed for use when considering exterior
angles like those labeled "angle a" in figure 19. Setting the
miter angle to these exterior angles yields the correct miter
angle for the frames shown in figure 19. The 90˚ scale is used
when considering interior angles like those labeled "angle b" in
figure 19. To use the 90˚ scale to make a frame like those
pictured in figure 19, divide the measured "angle b" by 2.
VERNIER SCALE
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 degree. To use the vernier scale follow these
steps.
CAUTION: Disconnect the saw from the power supply
before moving it or making any adjustments.
1. Set the miter angle to the nearest whole degree desired by
aligning the center mark in the vernier scale, shown in
figure 20, with the whole degree number etched in the miter
scale. Examine figure 20 closely; the setting shown is 24˚
right miter.
2. To set the the saw to miter an additional 1/4˚, move the first
mark to the right or left of center on the vernier scale until it

aligns with the closest degree mark on the miter scale. To
set the saw to miter 24-1/4˚ right, move the first mark to the
right of center on the vernier scale so that it aligns with the
closest degree mark on the miter scale: 25˚. Figure 21
shows a setting of 24-1/4˚ right miter.
3. To set the saw to miter an additional 1/2˚ , align the second
mark to the right or left of center on the vernier scale
(marked 1/2) with the nearest whole degree mark on the
miter scale. For example, to miter 24-1/2˚ to the right, move
the second mark to the right of the center to the right until
the 1/2˚ vernier mark aligns with the closest degree mark
on the miter scale.
4. To set the saw to an additional 3/4˚, align the third mark to
the right or left of center on the vernier scale with the
nearest whole degree number. For example, to miter 24-
3/4˚ to the right, move the third mark to the right of center
on the vernier scale to the right until it aligns with the
closest degree mark on the miter scale.

Making Fine Adjustments 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.
Making Fine Adjustments 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.
To cut molding at 90˚ to its surface, position the wood against
the fence and hold it tightly to the fence and table, as shown
in figure 22. Turn on the saw, allow the blade to reach full
speed and lower the arm smoothly through the cut.
