This feature allows the Magnum to machine the hinge mortises flush with the beveled edge of a double-
beveled door. The jamb can be held and machined at the same angle by installing the 6 jamb riser wedges
(item # 0001-741) which are included with the standard machine. The wedges slip over the jamb risers
and are held in place by a thumb screw on the side. The thin edge of the wedge points toward the door.
To change between 0 and 3-1/2 degree mortising, the following procedure is recommended (refer to fig
4-12):
1. Unplug the butt router motor.
2. Install the six jamb riser wedges.
3. Lower the butt router assembly.
4. Release both pivot lock pins by pulling the pin out and rotating it 90 degrees. Push down on the
butt router handle to cause the pivot blocks to move up in their slots. While still holding the handle
down, rotate the lock pins to allow them to lock the assembly in the “up” position.
5. Reverse the procedure to return the router to the normal position.
