Cautions
(Note 9) High-speed operating function
• This function means that a button always rests on
the shutter plate.
• Since the button carrier operates with the shutter
plate closed, a load is likely to be applied to the
shutter plate and the button carrier when the
machine is locked.
(Note 10) Not provided with the stitching timing
adjusting function. In the double-stepped action of
the button clamp (Nos. 5 to 7), the stitching timing
adjusting function is not necessary. So, the DEG,
SW-1 is used only to set the length of time required
to make the triple pawl actuate after the index
operated.
(Note 11) Function to adjust the button carrier
operating timing
• If the sewing product may be caught in the button
carrier when attaching buttons to hip pockects
or the like, this function can be used to delay the
actuation of the button carrier in accordance with
the length of time specified by the DEG, SW-1.
(Note 12) SW (Switch) stand-by
• The button carrier operates when the manual
operation switch on the operation panel is pressed.
• If the knee switch is used, connect it to the pins 9
and 10 of J24 on the control box. Then the “switch
stand-by” function can be used. (This feature is
available by a special order.)
(Caution)
• For all the functions controlled by the DIP switches
(DIP-SW), it is possible to stop the subsequent
action of the button carrier by pressing the manual
operating switch or the knee switch (special order
part) while the sewing machine is in opersation, and
to actuate the button carrier by pressing it again.
• If a button comes off the index unit, the machine
makes the button carrier actuate, with no button,
once after the completion of sewing to allow the
operator to remove the material from the machine
with ease.
• If, when the automatic button discharging function
works, the predetermined length of time for
fine positioning of a button has passed before
a button is placed on the button carrier, the
shutter plate will be opened and the button will
be discharged. At this time, it is possible that the
discharged button is accidentally placed on the
button carrier. In this case, the button carrier will
be actuated twice. As a result, two buttons will be
fed to the button carrier, causing needle breakage.
To prevent this, the time for starting the sewing
machine is retarded by 0.5 sec. if the automatic
button discharging function has actuated. (It is
possible to decrease the frequency of actuation
of the automatic button discharging function by
increasing the length of time during which the
machine performs fine positioning of a button.)
• When the double-stepped action of the button
clamp is selected and the operator operates the
pedal too quickly, the button clamp jaw levers
will go up before it opens after the completion of
sewing. In this case, the operator cannot smoothly
move the material on the machine. To prevent this,
the time for turning ON the button clamp jaw lever
lifting magnet should delay by 0.2 sec. to give
priority to mechanical actions.
