HOW TO USE A MOLDING CUTTERHEAD
To reduce the risk of injury, turn unit off
and disconnect it from power source before installing
and removing accessories, before adjusting or when
making repairs. An accidental start-up can cause injury.
The riving knife and blade guard
assemblies cannot be used when dadoing. It must be
removed as described in Riving Knife and Blade Guard
Operations section. Use EXTREME care when using
the dado without the blade guard assembly and riving
knife.
Use pushsticks, hold-downs, jigs,
fixtures or featherboards to help guide and control the
workpiece when the guard cannot be used.
Never use a molding cutterhead (R) Fig. 70
in a bevel position. Always use the proper molding
cutterhead throat plate (S).
Never run the stock between the fence
and the molding cutterhead. Irregular-shaped wood will
cause kickback.
To reduce the risk of injury, always return
and fasten the riving knife and blade guard assemblies
to the proper operating position for normal through
sawing operations. Also, be sure the standard throat
plate is back in position.
Give special attention to the grain
direction. Make all cuts in the same direction as the
grain whenever possible.
Molding is cutting a shape on the edge or face of the
workpiece with a special molding cutterhead.
The molding head consists of a cutterhead that can be
fitted with various shapes of steel cutters (Fig. 71). Each
of the three knives in a set is fitted into a groove in the
cutterhead and securely clamped with a screw. Keep the
knife grooves free of sawdust to allow the cutter to seat
properly.
NOTE: The standard outer arbor flange nut assembly
(M) Fig. 65 cannot be used with a molding cutterhead.
A special nut (N) is included with the Unisaw to be used
in these applications. Tighten this arbor nut against the
molding cutterhead. Do not discard the outer arbor
flange nut. It will be needed when reattaching the
standard blade to the arbor.

1. You can easily attach a molding cutterhead (R) Fig. 70 to the saw arbor. Also, you must use the accessory molding
cutterhead throat plate (S) in place of the standard throat plate. Be sure the throat plate is level to the table before
you proceed.
2. When using the molding cutterhead, add wood-facing (T) to the face of the rip fence (Fig. 72). Attach the wood
facing to the fence either with wood screws through holes drilled in the fence, or with two clamps. Stock that is 3/4"
(19 mm) thick is suitable for most work, although an occasional job may require 1" (25 mm) facing.
3. Position the wood-facing over the cutterhead with the cutterhead below the surface of the table. Turn the saw on
and raise the cutterhead. The cutterhead will cut its own groove in the wood-facing. Fig. 71 shows a typical molding
operation.
To reduce the risk of injury, always return and fasten the riving knife and blade guard assemblies to the
proper operating position for normal through sawing operations. Also, be sure the standard throat plate is back in
position
