A Twisted Corner is when the Blade Rotates before fully Retractingfrom the matboard, which tears the matboard and twists the corner. This is especially visible from the back of the mat. The FootBlock may become clogged with matboard debris over time, keeping it from plunging/retracting properly. See the Clean the Footblock procedure for instructions on cleaning it. Check to make sure the Rotation hasn't been set to too a high number. Twisted corners can also be a symptom of Oil/Water in the Air Valve, or an issue with the Head. Check the Air Regulator for excess water.  |
