4. Back off the adjusting screw on the side that the trim occurred, then tighten the other screw.

5. Tighten jam nuts and make another test. Continue to adjust and test until no trim occurs

when testing either sequence.

6. Replace the rear Plexiglas table cover.

Note: Once the backgauge is square, check the backgauge accuracy (see Section 3.5.2 below) to

make sure it is accurate.

3.5.2 Backgauge Accuracy Adjustment (Models: SA and A)

If the backgauge position readout does not match the actual measurement between the knife and the

bac

kgauge, the accuracy can be adjusted. The accuracy can be checked by the following procedure:

NOTE: The backgauge should be squared before attempting to adjust the accuracy. (See Section

3.5.1 , page 13).

1. Place a 1/4 to 1/2” lift of 8-1/2 x 11” paper against the center of the backgauge.

2. Using the backgauge position readout, bring the lift up to the 10.00” position and make a cut.

Then move the backgauge up to 5.00” and make another cut.

3. Take a sheet from the center of each lift and compare them to each other. The cutter will

always space accurately between cuts (in this case the 10” and 5” cuts) whether the overall

accuracy is correct of not (Figure 7, page 15). The front stack will be a true 5”, but the paper

left against the backgauge will not be if the backgauge position is inaccurate.
