TROUBLE SHOOTING HOW TO RAISE OR LOWER THE ACCEPTANCE NUMBER
With the brake lathe plugged in but not turning, push RESET and release, and wait for the READY TO START
light to be illuminated
With the READY light illuminated, press and hold the CALIBRATION button (located just below the lights)
until the ADJUSTING light illuminates, then release the CALIBRATION button.
Now the machine is displaying the acceptance number. Generally this should be 1.0.
To raise the acceptance number (loosen the calibration), press the START button once. To lower the accep-
tance number (tighten the calibration), press the CALIBRATION button once. The acceptance number will
change in increments of two. After raising or lowering, hit the RESET button to save the change.
Once you have raised or lowered the acceptance number by two and hit RESET, test the machine to ensure
that the problem has been solved. You may need to repeat the procedure once or twice to fully solve the
problem.
If you have any difficulty or questions about executing this procedure, call Pro-Cut.
