₹150.00
Wheel sensor for the Jack F4 direct-drive single needle sewing machine. It reads the handwheel (main shaft) position and passes it to the control box, so a faulty one causes wrong needle stop positions, erratic speed or position error codes.
Fits
- Jack F4 direct-drive single needle lockstitch machine
Signs the Sensor Is Failing
- Needle stops in the wrong position.
- Speed is uneven or the machine will not start properly.
- The display shows a position-related error.
How to Replace the Sensor
- First, switch off and unplug the machine.
- Next, find the sensor at the handwheel and note its position and cable route.
- Then fit the new sensor in the same place and reconnect the cable.
- Finally, power on and check the needle stop position.
FAQ
Could a position error be something else?
Yes. A loose sensor cable or a dirty sensor area can cause the same fault, so check the connector and clean around the sensor before replacing it.
Does it fit F5 or F6?
Do not assume so. This listing is for the F4; send a photo of your model plate and we will confirm.
