What to do if Iowa Precision Cornermatic Plus Industrial Equipment won't start but start switches are working?
- KKeith WeeksAug 4, 2025
If your Iowa Precision Industrial Equipment isn't starting or completing its cycle even though the start switches are working, the issue might be with the air valve. You can manually activate each air valve by turning the red screw on each valve clockwise about a quarter turn. Turning it counter-clockwise will turn the valve off. With the power off, cycle each valve at least 3 or 4 times to check for mechanical issues, broken parts, pinched or blocked air lines, low air pressure, or valve contamination.
