How can I get the needle dropped into sewing machine?

SOURCE: Machine is locked up

When you say you can't get the arm to move are you talking about the needle bar, if this is the case the chances are if you broke the needle there may be a piece stuck in the bobbib case area but can you be a bit more explicit. Thanks Ken [email protected]

SOURCE: FEW STITCHES DROP IN BOBBIN

Dropped stitches troubleshooting:
1>change to a new proper needle (proper needle means quilting needles for free motion, stretch needle for knits, leather needle for leather, microtex needle for micro fabrics.....etc.) of proper size. Most sewers never need a needle smaller then an 80/12 when sewing. Smaller needles bend more easily causing more problems.
2>If a new needle doesn’t fix the problem, remove parts from bobbin case area (as best as easily allowable) and clean out all the lint thoroughly, and oil with 2-3 drops of oil where friction occurs (turn hand wheel and look for rubbing)
3>If still skipping, try a different spool of thread (Yes, thread can caused skipped stitches, not common but I see it).
4>If you haven’t solved it yet, sounds like you could need to make a lower level adjustment like hook timing.
Hook Timing:
To time the machine, you want the tip of the hook to pass just over the top of the eye of the needle when the needle is in the left most or right most position depending on which side the eye of the needle will be higher

Before you put the cam in did you make sure the machine was set on straight stitch and then select zig zag?

Use a penny or a nickel in the screw head. Works like a charm

Testimonial: "Thanks!"

SOURCE: I have a Janome 6260. My machine sewed great, but

I've had the Lo come on my screen of my sewing machine also, but normally when I turned it off it corrected the jam up.
Lo- A button is pressed when the machine halts due to a overload
wait 15 seconds to recover
if thread jamming causes the overload, remove the tangled thread
check the bobbin area for lint & loose threads
also check to see if the bobbin is warped
check you needle to see if it's bent-roll on a flat surface to see if it rolls correctly
if it's blunt it makes a popping sound when going thru fabric
let me know if these suggestions help
