Needle Detectors
The machine is equipped with two needle detectors:
- On the right side of the carriage front
- On the left side of the carriage back
The needle detector (1) checks the height of the fabric in the needle area.

If needles are defective (e.g. latch breakage), there is a danger of the fabric not being taken down downward and gathering in the needle area.
The machine will then stop automatically to prevent from a major damage.
