When the green LED 4 is lit, the machine head is turned on. The three-way switch 3
determines the method of operation of the edge trimmer. At switch position I the edge
trimmer is switched on for normal applications. The switch position II is for the
turning-on of the edge trimmer at greater stitch lengths. At switch position 0 the function
is turned off.
When the yellow LED 2 blinks, the edge trimmer operates after the programmed
number of stitch count (Parameter 259 at the supplier level; Prerequisite: Parameter
255=2). The number of stitch count for the shutting-off of the edge trimmer is
established through parameter 258 at the supplier level.
