ADJUSTMENTS & MAINTENANCE
A. BLADE DEPTH ADJUSTMENT- BEVEL CUTTING HEAD
Tools needed: Screwdriver, Ruler
1. Hold the 702 Bevel Cutter upside down in your hand with the blade activated in the cutting position.
2. Looking at the tip of the blade, measure the exposed amount with a ruler at the same angle as the blade. For
standard thickness mat board (4 ply) only 1/8" of blade should be seen. To adjust, find the screw head recessed
below the bottom of the surface of the cutting head near where the blade is coming out. Fig. 4
3. Turning the screw to the right (clockwise) will decrease the blade depth, the left (counterclockwise) will increase
the blade depth. Not all matboard requires 1/8". Thicker matboard will require more. Always have the blade depth
set so that the Slip Sheet is scored only slightly. Cutting even half way through the Slip Sheet is entirely too much
blade depth. This extra blade depth allows the blade tip to flex and cause hooks and curves in the cut.
Extra blade depth can also cause the Start and Stop indicator to be incorrect which results in overcuts. This test and
adjustment needs to be done periodically as mat board has many variances of thickness and the depth can increase
itself over time with regular use.
B. RE-PARALLEL THE MAT GUIDE
Tools needed: Phillips Screwdriver, Ruler.
To re-parallel the Mat Guide, first determine that the Mat Guide is out of parallel by doing a parallel test.
Parallel Test:
1. Lock the Mat Guide at the 2" mark on the scale. Fig. 1
2. Place a scrap piece of matboard under the Guide Rail and up against the Mat Guide at the top end of the machine.
3. Using a pencil, mark a line across the mat.
4. Slide the mat all the way down to the bottom where you are standing keeping the mat against the mat guide but
not against the Squaring Arm.
5. Draw a line across the mat.
6. The piece of matboard should now appear to only have one single line across it. If the two lines drawn do not line
up with each other, the Mat Guide needs to be re-paralleled.
To Re-parallel:
1. Release the Mat Guide.
2. Use a Phillips head screwdriver to loosen the screws on either side of the black knobs one turn each. There are
four screws total to be loosened this way.
3. Place a metal ruler or suitable straight edge between the Mat Guide and the Guide Rail. Fig. 2
4. Slide the Mat Guide against the straight edge and the Guide Rail. Make sure both the Mat Guide and the Guide
Rail are making solid contact on both sides of the straight edge.
5. Re-tighten the Black Knobs first.
6. Then re-tighten the four screws. Do another parallel test to ensure that the Mat Guide is now parallel.
C. RE-SQUARE THE SQUARING ARM
Tools needed: Screwdriver, Carpenter's Square.
ATTENTION: It is common for 32" x 40" sheets of mat board to be un-square when bought. Take
this into account before making any adjustments to the Squaring Arm.
Before making any adjustments to the squaring arm, make sure that the machine is truly out of square, not
the mat board, by using the squareness test.
Squareness Test
1. Place the carpenter's square against the right hand side of the guide rail and down against the
squaring arm. Fig. 1 Look to see if there are any gaps between the framing square and the
squaring arm. If so, the squaring arm needs to be adjusted.
