Compoundmiter Cut - Craftsman 315.212010 Operator's Manual

[]
Release the switch trigger and allow the saw blade
to stop rotating before raising the blade out of the
workpiece. Wait until the electric brake stops blade
from turning before removing the workpiece from miter
table.

TO COMPOUND MITER CUT
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 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 interde-
pendent 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.
[] Loosen the miter lock handle.
[] Lift the miter lock plate to disengage.
[] Rotate the miter table until the pointer aligns with the
desired angle on the miter scale.
[] Release the miter lock plate.
NOTE: You can quickly locate 0°, 15 °, 22.5 °, 31.6 °, and
45 ° left or right by releasing the miter lock plate as you
rotate the control arm. The miter lock plate will seat
itself in one of the positive stop notches, located in the
base.

[] Retighten the miter lock handle securely.
[] Adjustments of the miter fence must be made to cor-
respond to the desired angle of the bevel cut prior to
tilting the saw arm. The fence is marked for 0°, 15 °,
30 °, or 45 ° . Loosen the fence screw on the miter fence,
slide the fence to the desired position, and retighten
the fence screw.
[] The 45 ° triangle on the miter fence provides for the
maximum clearance required for adjusting the miter
saw's angle when making a bevel or compound cut.
[] Loosen the bevel lock knob and move the saw arm to
the left or right 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, jam-
ming the blade.
[] When cutting long pieces of lumber or molding, sup-
port the opposite end of the stock with a roller stand or
with a work surface level with the saw table.
[] Align the cutting line on the workpiece with the edge of
saw blade.
[] Grasp the stock firmly with one hand and secure it
against the fence or use the work clamp or a C-clamp
to secure the workpiece when possible.
