(3) Starting
Depress the front part of the starting pedal, and the machine will start.
1. If the material does not reach the sensor, the sewing machine will not start even if you
depress the starting pedal. It is therefore necessary to place the material in the
predeterminded position without fail.
2. To lift the presser foot during sewing, depress the back part of the starting pedal.
(Do not fully depress the back part of pedal.)
(4) End of sewing
1) The chain-off thread sewing automatically starts when the material end comes off the sensor.
When the sewing machine has sewn the specified number of stitches of chain-off thread sewing, the
sewing machine stops and the presser foot goes up.
The sewing machine does not stop even if you release the starting pedal during the auto-
matic chain-off thread sewing.
Turn OFF the power in case of emergency.
2) For the setting of the (automatic) chain-off thread sewing speed and the number of stitches at the end of
sewing, refer to "@ -4. Various settings of the chain-off thread rolling-in sewing" and " @ -5. Chang-
