・ 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 insufficient, the cassette clamp device will not clamp a
cassette even when a cassette is inserted into the clamping position.

adjustment is insufficient, the sewing machine will fail to start sewing even if you press the
Start switch.
