3.5 Adjustments
Some of the following tests require the machine to be operational for
checking and adjusting. Be very careful that tools and other people are clear of moving parts and that
the cutter is not accidentally operated while adjustments are being made. Whenever possible,
disconnect the power and lock it out (see SAFETY PRECAUTIONS, page 6) unless the directions
specifically require the machine to be powered.
3.5.1 Squaring the Backgauge (All Models)
To test if the backgauge is square, place a small lift of paper against the left side of the backgauge
(bu
t not against the side guide) and make a cut. Now, 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 5). 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 5
To square the backgauge:
1. Make sure the backgauge gibs are set properly (see section 3.5.6 , page 18).
2. Remove the rear Plexiglas table cover.
3. Loosen the jam nuts on the backgauge adjusting screws (Figure 6, page 14).
