In
addition to the alignment of the cutter, you need to be sure you are
moving the cutter forward in the way it was designed. If you look at
the cutter from the side you will see two things. The most obvious
one is that the angles of the cutaway on the head are shallower at
the front and steeper at the back. In addition if you look
carefully, the axel for the wheel is slightly forward of the centre
line of the whole cutter.

So
it does not matter where the fixing screw on the head is. It may be
at the front or at the back. What matters is the cutaway at the back
which allows the cutter to be used with a shallower angle, than if
reversed. This is most obvious on wide cutter heads.
