Mitering (Fig. 40)
WARNING: Miter angles greater than 45˚ may force the blade guard assembly into the saw
blade causing damage to the blade guard assembly and personal injury. Before starting the
motor, test the operation by feeding the workpiece into the blade guard assembly. If the blade
guard assembly contacts the blade, place the workpiece under the blade guard assembly, not
touching the blade, before starting the motor.
CAUTION: Certain workpiece shapes, such as molding may not lift the blade guard
assembly properly. Feed the workpiece slowly to start the cut. If the blade guard assembly
contacts the blade, place the workpiece under the blade guard assembly, not touching the
blade, before starting the motor.
This operation is the same as crosscutting except the miter gauge is locked at an angle other
than 0°. Hold the workpiece FIRMLY against the miter gauge (J) and feed the workpiece
slowly into the blade (to prevent the workpiece from moving).
FIG. 40
Miter Gauge Operation
To set your miter gauge:
1. Loosen the miter gauge lock handle.
2. Move the miter gauge to the desired angle.
3. Tighten the miter gauge lock handle.
COMPOUND MITERING
This is a combination of bevel crosscutting and mitering. Follow the instructions for both bevel
crosscutting and mitering.
Dado Cutting
CAUTION: Do not attempt to stack dado blades thicker than 13/16" (20 mm). Do not use
dado blades larger than 8" (200 mm) diameter.
Since dado cuts are not thru-cuts, the cuts must be performed with the blade guard
assembly removed. To remove the blade guard assembly, pull riving knife/blade
guard release lever and pull up on the guard or riving knife to remove.
When using the dado, the special dado insert (also sold as an accessory) must be used.
Anytime a cut is required that is considerably wider than the saw kerf, a dado is used. A dado
cut is commonly used to add support and line up a shelf for a cabinet, bookcase or some
such project. When using the dado, the blade guard assembly must be removed. Use
EXTREME care when using the dado without the blade guard assembly and riving
knife. If a deep cut is required, use several successive passes rather than attempting to make
it with one pass. Maximum dado width on this saw is 13/16" (20 mm). DO NOT USE WIDER
COMBINATIONS.
J
CAUTION: Always check dado blade clearance before plugging in the saw.
Be sure to place the blade guard assembly and standard throat plate back in
position and check adjustments when the dado cuts are complete. Reinstall blade
guard assembly, anti-kickback assembly and riving knife.
Featherboard Construction (Fig. 41, 42)
Featherboards are used to keep the work in contact with the fence and table, and help
prevent kickbacks. Dimensions for making a typical featherboard are shown in Figure 41.
Make the featherboard from a straight piece of wood that is free of knots and cracks. Clamp
the featherboard to the fence and table so that the leading edge of the featherboard will
support the workpiece until the cut is complete (Fig. 42). An 8" (203 mm) high flat board can
be clamped to the rip fence and the featherboard can be clamped to the 8" (203 mm) high
board.

WARNING: Use featherboards for all non thru-sawing operations where the blade guard
assembly, anti-kickback assembly and riving knife cannot be used. Always replace the
blade guard assembly, anti-kickback assembly and riving knife when the non thru-
sawing operation is complete. Make sure the featherboard presses only on the portion of
the workpiece in front of the blade.
