3.4.1 Squaring the Backgauge
To test if the backgauge is square, place a small lift of paper against the left side of the backgauge
(but not against the side guide) and make a cut. Leave the backgauge in the same position, flip the
lift over and push it against the right side of the backgauge (but not against the side guide). Make
another cut to see if any of the paper will trim off (Figure 6). Run two checks, one starting on the left
and moving to the right; the other, moving from the right to the left. If paper is trimmed in either
sequence, the backgauge is out of square.
Figure 6
To square the backgauge:
1. Make sure the backgauge gibs are set properly (see section 3.4.5 ).
2. Loosen the jam nuts on the backgauge adjusting screws. (Figure 7).
Figure 7
3. Back off the adjusting screw on the side that the trim occurred, then tighten the other screw.
