-10- G3183 Hollow Chisel Mortiser
5. Feed the bit into the chuck until the tip of the
bit extends between
1
⁄16'' and
3
⁄16'' below the
tip of the chisel edge. Once you have prop-
erly aligned the bit and chisel, tighten the
chuck with the chuck key provided in the
package.
NOTE: If the bit extends beyond the maximum
3
⁄16'' below the chisel, even when fully engaged in
the chuck, it will be necessary to shorten the
shank of the bit to achieve proper clearance.
4. Insert the bit into the chisel, then insert both
through the bottom of the bushing. Loosen
the brass screw, if necessary, to allow the
chisel and bit to pass by. Push the chisel as
far as it will go into the head assembly.
Tighten the brass screw to hold the chisel in
position. Figure 9.
3. Place the bushing in the opening directly
under the chuck. Align the hole on the side
of the bushing with the threaded hole in the
front of the headstock. Once in place, thread
in the brass screw. Figure 8.
