  • Page 30 Sewing process Operation / Explanation Transfer-seam over-sewing - Operate knee switch. The speed of rotation is restricted to 2 000 stitches/min. - Pull pedal fully back and hold it there. At the end of the seam The finishing lock-stitch is sewn. The thread is cut off.
  • Page 31: Maintenance

    Maintenance Caution! Danger of injury! Turn off main switch! Maintenance may only be carried out with the sewing machine switched off. Maintenance work must be carried out no less frequently than at the intervals given in the tables (see “operating hours” column). Maintenance intervals may need to be shorter when processing heavy-shedding materials.

  • Page 34: Optional Equipment

    10. Optional equipment 10.1 Residual-thread monitor RFW 13-3/RFW 13-6/RFW 13-8/RFW 13-9 The residual-thread monitor monitors the amount of thread in the shuttle bobbin. An acoustic signal is sounded when only a small amount of thread is left. The operative can finish the seam and fit a new spool. This avoids material damage and thus any need for repairs.
  • Page 35 Caution! Danger of injury! Turn off main switch! The shuttle bobbin must not be changed unless the machine is switched off. – Change the bobbin. A new seam can now be sewn. IMPORTANT ! The bobbin must be put in place with the groove 2 facing downwards.
  • Page 36: 2Nd Stitch Length Stls 13 - 2

    10.2 2nd stitch length STLS 13 - 2 The facility to activate a 2nd stitch length makes it possible to switch rapidly from the assembly seam to the subsequent overstep seam. The 1st or 2nd stitch length is selected with the keys on the sewing arm. The 2nd stitch length is always smaller than the 1st.
