B. Adjusting moveable knife and fixed knife
a) As can be seen in figure 34, it is normal that the position
of the fixed blade is at the center of fixed knife.
b) Notice if
part is widened, a thread is spitted into three
pieces and then the thread falls out of needle after
trimming. And a widened
part causes trimming miss.
[Figure 34]
C. Adjusting the trimmer driving part

b) Fix the trimming cam final crank to the trimming shaft as
in the picture.
c) Attach the stopper lever closely to bed in order to run
