angles to the nearest 1/4 degree. 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 degree 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 V1, with the whole degree num-
ber etched in the miter scale. Examine Figure V2
closely; the setting shown is 24 degrees right miter.
3. To set the additional 1/4 degree, squeeze the miter
arm lock and carefully move the arm to the RIGHT until
the 1/4 degree 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 degrees. Figure V2 shows a setting of 24-1/4
degrees right miter.
For settings that require partial degrees (1/4, 1/2,
3/4 degrees) align the desired vernier mark with the
CLOSEST degree mark on the miter scale, as described
below (The plastic vernier plate is inscribed with marks for
1/4, 1/2, 3/4 and 1 degrees. Only the 1/2 degree and the
1 degree are 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 degree cuts:
Position the wood against the fence and hold it in place
as shown in Figure 16. Turn on the saw, allow the blade
to reach full speed and lower the arm smoothly through
the cut.
CUTTING BASE MOLDING UP TO 6" (152.4mm)
VERTICALLY AGAINST THE FENCE
Position material as shown in Figure 16.
All cuts made with the back of the molding against the
fence and bottom of the molding against the base.

CUTTING CROWN MOLDING

Your miter saw is better suited to the task of cutting
crown molding than any tool made. In order to fit properly,
crown molding must be compound mitered with extreme
accuracy.
The two flat surfaces on a given piece of crown molding
FIG. 17
are at angles that, when added together, equal exactly 90
degrees. Most, but not all, crown molding has a top rear
angle (the section that fits flat against the ceiling) of 52
degrees and a bottom rear angle (the part that fits flat
against the wall) of 38 degrees.
Your miter saw has special pre-set miter latch points at
31.62 degrees left and right for cutting crown molding at the
proper angle and bevel stop pawls at 33.85˚ left and right.
TABLE
There is also a mark on the bevel scale at 33.85 degrees.
The chart below gives the proper settings for cutting crown
molding. (The numbers for the miter and bevel settings are
very precise and are not easy to accurately set on your
saw.) Since most rooms do not have angles of precisely 90
degrees, you will have to fine tune your settings anyway.
PRETESTING WITH SCRAP MATERIAL IS
EXTREMELY IMPORTANT!
