If both the needle and the hand wheel on your Singer 140Q sewing machine are jammed, it indicates a more serious issue that likely requires attention. Here are some steps you can take to troubleshoot and possibly resolve the problem:
1. Turn Off the Machine: Start by turning off the sewing machine and unplugging it from the power source. This ensures safety while you troubleshoot the issue.
2. Check for Obstructions: Inspect the area around the needle and hand wheel for any obstructions such as broken needles, tangled thread, or debris. Remove any obstructions carefully.
3. Rotate the Hand wheel: Gently try to rotate the hand wheel manually. If it's stuck, avoid forcing it as this could cause further damage. Instead, try to identify what's causing the jam by examining the mechanism closely.
4. Inspect the Bobbin Area: Open the bobbin case and remove the bobbin. Check for any tangles of thread or debris that could be causing the jam. Clean the bobbin area thoroughly.
5. Check the Needle: Remove the needle and inspect it for any damage. Replace the needle if it's bent, dull, or damaged in any way.
6. Oil the Machine: Lubrication is important for smooth operation. Apply a drop of sewing machine oil to the moving parts, such as the hand wheel shaft and other points indicated in your machine's manual.
7. Professional Inspection: If you're unable to resolve the issue on your own, consider taking your sewing machine to a qualified technician for inspection and repair. They can diagnose the problem accurately and perform any necessary repairs.
Attempting to force the machine to work when it's jammed can potentially cause further damage. So, proceed with caution and prioritize safety while troubleshooting the issue.
SOURCE: bobbin case case keeps jamming
I am having somewhat the same problem with the exception that my needle did not break. I've cleaned and oil, but the bobbin case and projection positioned spring is not communicating to allow sewing to continue. The thread keeps jamming and the bobbin raises up the plate. So, what else am I to do?
SOURCE: hand wheel is stuck
hi there,
well,stuck up hand wheel, is due to mechanical obstruction inside machine,bushing on shafting need to oil,and on handwheel bushing near clutch there is oil port there. since hand wheel are connected to cam shaft with set of gears and pulley is coupled to motor pulley,and other linkage under bobbins,shuttle race etc,broken gears are most common causes of stuck up handwheel,we can consider also the brush carbon,when worn out and damage the rotor commutator brush.if you can open the cover of motor below side of handwheel,you can see the pulley and motor assembly.also on top of machine there an opening to see the top gear assembly,this should be done by service technician.try to bring to nearest service center if still under warranty claim this for lesser maintenance cost.have a nice day,don't forget to rate me.thank's.

SOURCE: The bobbin case on my Singer Inspiration 4210
unscrew the black plate that holds in the bobbin case and move it over to the left just a little bit, but make sure there is still clearance between the lower right corner of the case and the plate. The case should be able to wiggle a little, but not so loose it can pop out..
