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
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
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.
