loosen
the
screw
® @Fig.35 and makeadjustment so that the
shank button holding clamp © holds the exact center of the button.
To
adjust
the
holding
pressure
of the
shank
button
holding
clamp
®, loosen the thrust collar set screw ®, Fig. 35, and if the thrust collar
® Fig. 35 is rotated, the
pressure
of the spring will change, so set it at
an optimal pressure.
When you do
this,
be sure that the button clamp lever holding
® Fig. 35 will not develop any rattling along the shaft direction.
G.
In order to attach the shank button
securely,
try to minimize
the
cross-wise
feed as much as possible.
To maintain a stable stitching condition, make doubly sure that the
needle is not contacting the needle
groove
of the adapter or the button
clamp work support plate, then start the button attaching task.
The holding pressure of the button holding clamp ® Fig. 35 should
be sufficiently strong enough so that the button does not move during
the stitching operation.
