SAFETY DETECTOR
■
The safety detector is included so that the machine
will not run if the thread trimmer does not return
home safely after the operation. Switch A on the
safety detector must be ON (switch A is pressed)
during sewing (the thread trimmer is completely at
home). Adjustment is made by loosening screws B
and E and moving brackets C and D as required.
