3-3. Adjustment method (Adjusting the position of the automatic switch)
When you carry out adjustment with the power to the sewing machine ON, the air is expelled from the
cylinder. Carry out setting in this state. Carry out the work while carefully protecting your ngers, etc.
from being caught in the clamp device.

❸❸❹
1) With respect to cassette mounting plate ❹,
put left chuck ❶into the state as shown in
the gure. Detach spring ❸once. Then,
carry out the aforementioned work.
2) In the state shown in the gure, move sen-
sor (marker No. 5) ❷to such a position that
the sensor LED lights up. Tighten the screw
to secure the sensor.
3) For the sensor (marker No. 6) on the right
side, also carry out the aforementioned
adjustment as described in 1 and 2.
4) Insert chuck base ❺between chuck ❶and
cassette mounting plate ❹so that chuck ❶
rmly holds chuck base ❺.
5) In the state as shown in the gure, move
the sensor (marker No. 7) to the position at
which the LED lights up. Then, tighten the
screw to secure the sensor at that position.
6) For the sensor (marker No. 8) on the right
side, also carry out the aforementioned
adjustment as described in 5).

❺❺
❶
【Point】
・
When the sensors (marker Nos. 5 and 6) are both ON, the air is supplied to the air cylinders to
clamp the cassette.
・
If the aforementioned adjustment is insu󰀩cient, the cassette clamp device will not clamp a
cassette even when a cassette is inserted into the clamping position.
【Point】
* The sensors (marker Nos. 7 and 8) work to conrm that the cassette is clamped. The "Start"
instruction is accepted only when both of these sensors are ON. If the aforementioned
adjustment is insu󰀩cient, the sewing machine will fail to start sewing even if you press the
Start switch.
7) After the completion of the adjustment, turn the power OFF.
3-4. Bundle wires of the automatic switch and air tubes
Move the feed by hand to conrm that the air tubes, etc. are not caught on the mechanisms, and that
the air tubes and automatic switch wires have some slack regardless of the position of the feed.

4. Setting the operation panel
4-1. Setting input/output of the ports
In order to use the cassette clamping function, input/output of the ports have to be set.
For the input/output settings of the ports, the following settings have been factory-set as default values.
If you have not changed the aforementioned settings, input/output setting of the ports is not necessary.
If you have changed the settings, set the ports as shown in the table given below. Refer to "4-4. Setting
the ports" p.12 or to the Engineer's Manual for the input/output settings of the ports.

5. Operation procedure
❷
❶
1) When you press the Ready
key, the origin is retrieved,
then, the feeding frame goes
up and the cassette chuck
opens. Be aware that, if a
cassette is inserted into the
cassette clamp, it will be auto-
matically discharged.
3) When you depress the
2-pedal unit switch Bor
3-pedal unit switch Cwhile
the feeding frame is in its
lower position, the sewing
machine will start sewing.
If the sewing machine fails
to start, the cassette is not
securely clamped. Discharge
the cassette once and re-
clamp it.
In order to discharge the
cassette that has been in
place once, depress the
2-pedal unit switch A. When
the 3-pedal unit is used and
the K194 is set to "Auto-
matic", press the switch B
to discharge the cassette.
Or, when the K194 is set to
"Manual", press the switch
Bto lift the feeding frame
and press the switch Ato
discharge the cassette.

【In the case of the 2-pedal unit (U81 and U82: 0)】
2) In the case the K194 is set to "Automatic", the
cassette will be automatically clamped after you
have inserted one into the clamp section.
In the case the K194 is set to "Manual", the
feeding frame will be lowered by depressing the
2-pedal unit switch Aor 3-pedal unit switch B
with the cassette being clamped.
【In the case the 3-pedal unit (U81 and U82: 2)】
4) After the completion of sewing, the sewing machine moves to the second origin (or to the sewing
starting point if the second origin is not set). After that, the feeding frame goes up. Then, the cassette is
discharged. After the aforementioned operation is carried out in the written order, the sewing machine
will return to the ready state.
