4 Inserting needles
Caution !
Switch off the main switch and remove your feet from the pedals on the machine support
before replacing needles so that the machine may not be started by unintended treading on
the pedal.
Fig.3
Having chosen the right thickness (size) of needle whose system coresponds to the prescribed
kind (usually 134 LR) loosen screw (A,fig.3) on needle bar and insert needle (B) as far as it will
go, i.e. up to the bottom of the needle hole in the needle bar. Turn the needle so that the recess
above the needle eye facs the looper point. Caution – when a greater needle size has ben chosen
it is necessary to check if the looper point does not catch the needle – a possible adjustment of
looper position must be carried out by an autorised person. Make sure that the needle passes
through the middle of the stitch plate opening. If it is not the case, check up if the needle is not
bent. Replace the defective needle.
5 Replacing Hook Bobbin, Threading Hook Thread
The thread passes from the bobbin case (A) through slot (B) under spring (C) into the looper
(fig. 4) in such a way that the thread will be unwound from the bobbin in the direction of the
arrow. Hold a thread end of ca. 5-6 cm and insert the bobbin case containing bobbin into the
hook in such a way so that the thread can be unwound from the bobbin smoothly. Lock the
bobbin case (A) in the looper using the lock (E).
Fig.4 Fig.5
Use screw (fig. 5) to adjust fhe tension of the thread unwound from the bobbin. Turn it in the
(+) direction to increase the thread tension or in the (-) direction to decrease the tension.
