Sewing Studio manual

Learn how to operate and adjust the industrial sewing machines, and learn how to use the steam iron unit. The instruction videos (5) will show you in detail how to operate and adjust the machines.


  • Select the machine according to its intended use (see machine descriptions).
  • Turn off the machine when changing the bobbin / needle, and when checking the threading.
  • Eye and finger protection components cannot be removed.
  • The machines are extremely rarely broken. Usually, the problems are caused by issues with threading or the condition of the needle. Be patient and try to solve the problem.

2. Overlockers

Overlockers are ideal for finishes and for sewing stretchy materials. The stitching is flexible.

The use of overlockers differs from sewing machines

  • Usually operated with 3 or 4 threads, which are thinner (120) or crêpe threads.
  • Needle threads (1–2) run on top of the machine.
  • Looper threads (2) run inside the machine.
  • You cannot backstitch on an overlocker, sew past the edge of the fabric to finish off. The remaining tail must be separately finished to stop the seam from unravelling.
  • Some overlockers have a cutting blade.
  • The pressure foot can be lifted using the small pedal, and you can move forward by using the larger pedal.
Adjusting the machine settings

  • The basic settings (thread tension) are good for most materials.
  • Overlockers are challenging to adjust, do not do it alone.
  • The workshop master can help if adjustment is needed, for example, to create a very stretchy stitch.

Lifting the pressure foot and cutting the thread

  • A separate small pedal, no automatic cutting of thread.

Cutting blade

  • All material on the right side of the blade is cut off.
  • Do not sew over needles, the blade will become blunt and unusable.


  • See device-specific set of needles.
  • 2 needles, you can use only one needle for a three-thread overlock.
