(1) - 2nd Needle thread guide
(2) - 2nd Needle thread tension
Twin-needle machines have a second tensioning wheel and
a second thread guide on the machine arm, to accommodate
both the needle thread and the looper thread.
The thread puller and the other thread guides on all machines
have two holes so that two threads can also be threaded.
The threading procedure corresponds to that for the single-needle
machines.
Important
Take care when threading the machine that the threads do not
cross over one another
