Calibration and Alignment of the Straight Line Trimmer: Trim a Mat | |
|---|---|
Place a piece of matboard at the 10” mark, and using the Trimmer, trim it. Measure the width of the matboard. If it does not measure 10” across the top and across the bottom, the Trimmer needs to be calibrated. | |
Calibrate the Bottom of the Straight Line Trimmer | |
|---|---|
Start with the bottom. Loosen the bottom Locking Knob by turning it Clockwise. | |
Using a 7/16” Open-Ended Wrench, loosen the Locking Nut. Using a 3/16” Allen Wrench, turn the Alignment Adjustment Screw Clockwise to move the Trimmer to the Right; turn it Counter-Clockwise to move the Trimmer to the left. When moving to the Left, you will need to push the Trimmer to the Left so that the Alignment Adjustment Screw stays on contact with the rail. | |
Tighten the bottom Locking Knob by turning it Counter-Clockwise. Cut the mat again... remember we are looking at the bottom of the mat. When the bottom of the matboard cuts the correct width, retighten the Locking Nut to keep the Alignment Adjustment Screw from moving. | |
Calibrate the Top of the Straight Line Trimmer | |
|---|---|
Trim a tall piece of matboard at 10” and measure across the top and across the bottom. If it does not measure 10” across the top and across the bottom, continue. Loosen the top locking knob by turning it Counter-Clockwise. | |
Using a 7/16” Open-Ended Wrench, loosen the Locking Nut. | |
Turn the Alignment Adjustment Screw Clockwise to move the Trimmer to the Right; turn it Counter-Clockwise to move the Trimmer to the Left. When moving to the Left, you will need to push the Trimmer to the Left so that the Alignment Adjustment Screw stays on contact with the rail. Tighten the top locking knob by turning it Clockwise. Cut the mat again, and readjust if necessary. When the top of the matboard cuts the correct width, retighten the Locking Nut to keep the Alignment Adjustment Screw from moving. | |
