tion, remove chain 6 for use.
When simultaneously performing presser foot lifting
and open/close of the hemming binder by pedal opera-
tion, remove knee pad plate (asm.) 7 for use.
＊ When the lifting amount of the upper feed roller is insuf-
fi cient, move hinge screw !0 to !1 . The lifting amount of
the upper feed roller increased with the same operating
