WARNING: The shaft brake is an emergency brake. If the main shaft brake pressure is too high, machine
mechanisms may work incorrectly; especially the stopping mechanism. Set the lowest possible pressure.
3.2 Main cam brake adjustment
The main cam brake affects the stitch density, which is adjusted as in chapter 2. It is a specification given by the
manufacturer to set up the distance between stitches. It is necessary to adjust the brake belt again after some
machine operation because of wear out.
