4. Start the saw motor and allow the blade to come up to speed.
5. While using both hands to keep the workpiece against the face of the miter gauge,
and holding the workpiece flat against the table, slowly push the workpiece through the
blade.
6. Never try to pull the workpiece with the blade turning. Turn the switch off, allow the blade
to stop, and carefully slide the workpiece out.
CAUTION: Never touch or hold onto the "free" or "cut off" end of the workpiece.
Bevel Crosscutting
This operation is the same as crosscutting except that the bevel angle is set to an angle
other than 0°. For proper hand position, refer to Figure 38.
FIG. 38
WARNING: Before connecting the table saw to the power source or operating the
saw, always inspect the blade guard assembly and riving knife for proper alignment and
clearance with saw blade. Check alignment after each change of bevel angle.
Mitering
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 (Fig. 39) and feed the
workpiece slowly into the blade (to prevent the workpiece from moving).
FIG. 39
Miter Gauge Operation
To set your miter gauge, loosen the lock handle and move the miter gauge to the desired
angle.
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. When installing the dado stack, do not
include the inner clamp washer. Replace it with the outer clamp washer, then install the
blade stack, arbor nut, and tighten with the wrench supplied.
Since dado cuts are not through cuts, the cuts must be performed with the blade
guard assembly removed. To remove the blade guard assembly, lift guard lock lever
(N) and remove (Fig. 15).
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.
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
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 40.
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. 41). 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.
