TO COMPOUND MITER CUT
See Figures 30 - 31.
A compound miter cut is a cut made using a miter angle and
a bevel angle at the same time. This type of cut is used to
make picture frames, cut molding, make boxes with sloping
sides, and for certain roof framing cuts.
To make this type of cut the miter table must be rotated
to the correct angle and the saw arm must be tilted to the
correct bevel angle. Care should always be taken when
making compound miter setups due to the interaction of
the two angle settings.
Adjustments of miter and bevel settings are interdependent
with one another. Each time you adjust the miter setting you
change the effect of the bevel setting. Also, each time you
adjust the bevel setting you change the effect of the miter
setting.
It may take several settings to obtain the desired cut. The
first angle setting should be checked after setting the second
angle, since adjusting the second angle affects the first.
Once the two correct settings for a particular cut have been
obtained, always make a test cut in scrap material before
making a finish cut in good material.
NOTE: It may be necessary to adjust or remove the sliding
miter fence to insure proper clearance prior to making the cut.
 Pull out the lock pin and lift saw arm to its full height.
 Loosen the miter lock knob approximately one-half turn
and squeeze the detent release lever.
 Rotate the miter table until the pointer aligns with the
desired angle on the miter scale.
 Release the detent release lever, then tighten the miter
lock knob to secure the miter table.
NOTE: You can quickly locate 0°, 15°, 22-1/2°, 31.6°, and
45° left or right by releasing the detent release lever as
you rotate the miter table. The miter table will seat itself
in one of the positive stop notches, located in the miter
table base.
 Loosen the bevel lock knob and move the saw arm to the
desired left bevel angle.
NOTE: To obtain right bevel angles, pull the bevel stop
pin out and tilt the saw to the desired right bevel angle.
 Left and right bevel angles can be set from 0° to 45°.
 Once the saw arm has been set at the desired angle,
securely tighten the bevel lock knob.
 Recheck miter angle setting. Make a test cut in scrap
material.
 Place the workpiece flat on the miter table with one edge
securely against the fence. If the board is warped, place
the convex side against the fence. If the concave edge
of a board is placed against the fence, the board could
collapse on the blade at the end of the cut, jamming the
blade. See Figures 39 - 40.
 When cutting long pieces of lumber or molding, support
the opposite end of the stock with a roller stand or with
a work surface level with the saw table. See Figure 34.
