* On subclasses -3/51 and -4/51, for a cutting length of 31.7 mm and more, the knife must
be at least 16.0 mm long. On the subclass -5/51, for a cutting length of 45 mm and more,
the knife must be at least 22.2 m long.
Each time parts are changed, the control unit must be adapted to the sub-class,
see Chapter Kapitel 8.04 Setting up the machine control unit. An incorrect
setting can cause the knife or needle to strike the work clamp.
