Why does my Asgard Angle Head leave edges?

Asgard Angle Heads are factory calibrated to feather both edges of the inside corner joint at the same time. If your angle head is leaving edges on one side of the corner, be sure to apply equal pressure to both sides of the angle head by keeping the tool and the handle centered in the corner. It's also possible that the corner itself is not square (90 degrees), causing the angle head to make more contact on one side than the other. If the edges are occurring on both sides of the inside corner joint, the blades of the corner finisher are most likely worn. We recommend you have the blades replaced and calibrated using TapeTech ProService.
