(Caution) 1. Adjust the position only when there ls a concrete problem that presser 8 and
top
feed dog 8 come
in
contact
with
each
other
and noise occurs, the
left
and
right
clearances are excessively different from each other and trouble occurs, etc.
2. When the adjustment value ls improper, there
is
the possibility that contact among
the components occurs, a bad influence Is given to the durability
of
the sewing
machine
or
the like since the
top
feed mechanism is strictly assembled because
of
the
space. So, be careful.
