Calibrating Miter Detent System
1.Engage the miter detent at the 0° position.
Loosen the miter lock knob 1/2 turn.
2.Look for four round holes in the miter scale
plate. In each hole is a screw. Use the small

4.Hold one side of a 90° combination square
against the fence and rotate the table (and
detent plate) until the side of the saw blade
is in full contact with the other side of the
square.
5.Tighten all four screws – loosen and reset the
miter scale pointer to the "0" position.

tion.
