Bernina L850 234Thread Freearm Overlocker Serger 3-9mm Wide 1Step Jet Air Looper Threading, Needle Threader, Knee Lift, Swing Foot, ExtTable, DC Motor

Threading the loopers on this machine is a dream come true. By operating the air threader with the BERNINA Foot Control, your hands remain free to do other things. You can even thread both loopers at one time, if you are so inclined. Turn the air threader connector knob to the left to set the machine for threading. Then press the foot control. The machine has a feature called Pulse Drive. What this means is that the machine will slowly sew into the correct position for threading when pressing on the foot control. You do not need to move the handwheel to set the machine for threading. Once the air threader pipes are closed, you will hear the air threading motor—it is a nice quiet sound. Hover the end of the looper threads over the air threading nozzles and the powerful air threader will actually pull the thread into the nozzle and through the looper eye. You will need a length of thread approximately 20-25” in length to clear the looper eye. The key advantage here is how smooth and unfussy this whole process becomes–the entire looper threading process is achieved with just One-Step!
