  • Page 4 WARNINGS Power down the yarn feeder’s power supply box mains switch before beginning any power supply hook-up, maintenance or part replacement operations. During standard machine operation, the yarn feeder may suddenly start up without prior warning. CAUTION: the orange lights do not signal that the yarn feeder is ON, but that the feeder has gone into an alarm mode.
  • Page 5 WARNINGS ADVICE TO ALWAYS KEEP THE FEEDER IN PERFECT WORKING ORDER AND EXTEND ITS SERVICE LIFE. For an always satisfying performance of the yarn feeder over the years, we deem it advisable to provide you with some simple tricks: 1. At the time of installation, passing from the store to the warm knitting environment, Condensation may form on a yarn feeder that has been stored in cold places when this is brought into a warm area.
