Stitching timing (Note 6)
• The length of time during which the button
carrier operates and the button clamp jaw
levers are in their highest position waiting
for a button.
0 → 0.05 SEC
8 → 0.05
1 → 0.10
9 → 0.10
2 → 0.15 : Standard
A → 0.15
3 → 0.20
B → 0.20
4 → 0.25
C → 0.25
5 → 0.30
D → 0.30
6 → 0.35
E → 0.35
7 → 0.40
F → 0.40
(The length of time during which the index
operates is fixed at the following values.)
0 to 7 → 0.08 SEC
8 to F → 0.16
The longer the aforementioned length of time
is specified, the better the overall timing of the
sewing machine will become.
Releasing the pedal while the sewing machine
is in operation will retard the time at which the
button carrier actuates by one second.
Since the function of adjusting the stitching
timing is not provided, DEG-1 has the function
of setting the length of time at which the triple
pawl actuates after the index has operated.

Cautions
(Note 1) The continuous cycle mode is a state where
the sewing machine is operated with the pedal held
depressed. The button clamp jaw levers go up, and
come down after waiting for the period of set time.
Then the sewing machine starts.
(Note 2) When the double stepped action function of
the button clamp is selected, depress the pedal
every time to operate the button clamp.
(Note 3) Automatic stitching mode
• When the automatic stitching mode is specified,
the fine positioning completion detecting sensor
will function. This means that the sewing machine
will not start unless a button is supplied to the
button clamp jaw levers.
(Note 4) Normal operation function
• Function to place no button on the shutter plate
excluding fine positioning of a button.
• A load is not likely to be applied to the shutter
plate and the carrier. As a result, the related
components do not easily break.
(Note 5) Automatic button discharging function
• If the fine positioning completion sensor fails to
detect the completion of the fine positioning of
button to feed a button, and the predetermined
time to perform fine positioning is exceeded, the
machine will automatically release the shutter
plate to make the button carrier actuate. If the
button discharging function is performed three
times continuously, ERROR 3 will result. To reset
the ERROR, press the MANUAL operation switch.
If the automatic discharging occurs frequently,
suppose that some mechanical trouble has
occurred and check the mechanical components
for failure.
(Note 6) Stitching timing adjusting function
(DEG, SW-1)
• This function is effective only when the continuous
stitching function is specified (Nos. 1 to 4).
• When one to four buttons are continuously sewn,
the sewing speed will gradually decrease by
stages and the length of time required to sew the
buttons will change. As a result, the operator's
constant sewing rhythm will be disturbed. To
achieve a constant sewing speed, this function is
used to adjust the length of time required to sew
the first to third buttons to that is required to sew
the fourth button.
(Note 7) Function to adjust the length of time required
to finely position a button (DEG, SW-2)
• This function is used to set the time to actuate the
automatic button discharging function.
• This function is also used to set the length of
time during which the fine positioner operates
when the prospective button feeding function is
specified.
(Note 8) Prospective button feeding function
• Use this function when sewing a button which has
a recess on the surface (the difference in height
between the bottom of recess and edge is 1 mm
or more.).
• When this function is used, the fine positioning
completion detecting sensor becomes inoperative.
So, the machine performs fine positioning of a
button for the length of time set using the DEG,
SW-2, and the machine, every time, opens the
shutter plate and actuates the button carrier
constantly at the predetermined time. This means
that the length of time required for sewing is likely
to change when compared with the sewing under
the automatic sewing mode. When this function
is used, the fine positioning completion detecting
sensor becomes inoperative. Consequently, the
sewing machine starts even when a button is
not fed to the button clamp jaw levers. When this
function is used, ERROR 3, which occurs when
the automatic button discharging function is
used, will not occur.
