TO COMPOUND MITER CUT
See Figures 28 - 29.
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, and make boxes with
sloping sides.
To make this type of cut the control arm on 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.
 Pull out the lock pin and lift saw arm to its full height.
 Lift the miter lock lever to unlock the miter table.
 Rotate the miter table until the pointer aligns with zero
on the miter scale.
NOTE: You can quickly locate 0°, 15°, 22-1/2°, left or right,
31.62° and 45° left or right as you rotate the control arm.
The miter table will seat itself in one of the positive stop
index points, located in base.
 Push the miter lock lever down to lock the miter table.
 Loosen the bevel lock knob and move the saw arm to
the left to the desired bevel angle.
 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 32 - 33.
 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 30.
 Align the cutting line on the workpiece with the edge of
saw blade or laser line.
