-Set air compressor to 60-80psi.  Pressure regulator dial near the back of the cutter should point nominally up.  I don’t know the reading at that setting, it was obscured by a post on the cart.  We should note that number here. +Set air compressor to 60-80psi. Pressure regulator dial near the back of the cutter should point nominally up. I don’t know the reading at that setting, it was obscured by a post on the cart. We should note that number here. Current setting should also point (mostly) up, about 25A for most thinner material, like 16gu plate.

-Check the height gauge, which looks likely to be made from a simple 16gu sheet (0.060”).  Ideally you want the height of the cut head to be about 1.5 times the thickness of this gauge above your material.+Check the height gauge, which looks likely to be made from a simple 16gu sheet (0.060”).
