Go to Singer at and you can buy a hard cover instruction manual for $15.. Your needle shaft may be bent so that it is hitting the presser foot.

My juki HZL7700 break the needle how i can solve this problem?

Check that you are using the correct needle for your machine--a needle of the incorrect length will most likely hit where it shouldn't. Then be sure to use a heavy enough needle so it will not bend when stitching heavy fabric. Next, do not pull or push the fabric when stitching as that will tend to bend the needle. If those check out, then there is most likely a timing issue where the needle is arriving at the wrong time. Best to take it for service.

Why is bobbin thread jamming on fabric

First, remove the bobbin and clean the entire area; if your machine model has a bobbin case, be sure to remove any lint from between the overlap. Change to a new bobbin in case the bobbin is wound poorly (happens even to pre-wounds).

Check thread paths of bobbin and top threads and be sure tension isn't too loose in bobbin or top; sometimes the auto tension changes erratically when stitching on thick fabrics, check your manual for resetting it to default or for making adjustments.

Be sure the needle is one that is the right size and type for the fabric you're stitching on and use a new one; bent needles happen easy, and a slight, almost undetectable bend will cause this type of issue.

My brother started making a loud noise when sewing pant fabrics

Your machine is complaining because it doesn't have the power to push through the layers of fabric. That clunking noise is the gears in the machine skipping and being sheered off (or it will be eventually) STOP!

If you feel that you need to continue... stop when it does this noise and use the HAND WHEEL. You'll also need to make sure that the presser foot remains level while going over thick seams.

Machine stitches 2 0r 3 stitch then skips stitches on rest of seam

try changing the needle
Sewing machine skips stitches
needle inserted incorrectly--flat side of the needle faces the shaft
round needle--groove of needle faces away from the shaft
Raise the needle bar to the highest point, then loosen the clamp screw to remove the needle. Place the new needle in the clamp with the flat side of the needle facing the back of the machine.
If round needle--the groove in the needle faces away from the shaft
Push needle all the way up to the stop or as far as it will go.
possible bent needle--lay needle on flat surface & roll needle over, if the needle does not roll good -replace
blunt needle point--needle makes a popping sound when needle penetrates the fabric--replace needle
needle not all the way up in needle holder--loosen needle clamp screw & push the needle up until it stops then tighten screw
incorrect threading--one step missed in sequence of threading can cause machine to skip stitches
wrong needle in machine--check instruction manual--some machines can use a generic needle with no problem--some can't--
size of needle & thread not compatible--
Using the wrong type needle can cause problems,,
A needle to fine for heavy fabric can bend or break when it hit's the fabric
And a too large needle can make puncture holes in the fabric and pull unevenly while stitching

Kenmore 385-16231 sewing machine. we are having problems with it breaking needles while sewing, we have never oiled this machine could this cause the needle breaking problem?

some sewing machines are self oiling some are not, instruction manual should tell,, when a sewing machine breaks needles it very possible that the machine is out of time & only a sewing machine repair shop has the tools to time the machine

I have a Mini Ultra machine. Sometimes when I am sewing a heavy weight fabric the needle jams -- that is, it hits the plate instead of going through the opening. What is wrong and what can I do?

Most likely reason is the needle is bending. Try using a thicker needle. Heavyweight fabrics such as denim, duck and canvas. Use a 90/14 or a 100/16 needle if sewing on these fabrics; a lighter 70/10 or 80/12 if sewing on cotton. Singer codes this with a blue top.

I have everything in place to sew, the needle is in the fabric, I push the pedal, and it won't go and makes a horrible noise, the wheel turns about 1/2 a turn and then just stops.

see if it will work without the needle .. make sure the needle is not bent .. make sure you dont have a single (non zigzag) foot on the machine while its in zig zag mode .. the needle will hit the foot in this case .. if the machine will run without a needle and fails even with a straight needle then there could be a timing issue .. the top part of the sewing machine is syncronized with the bottom part via a shaft and some gears .. these are adjustable by a tech person .. everything has to happen at the right time if that relationship is changed thru slipage or wear then the machine may jam up .. also if some cloth, thread or lint is cought in the bottom unit it can cause the trouble .. will it turn by hand ?? if it turns by hand freely but wont turn with the motor ... and it makes a lot of noise .. you may have a loose belt from the motor .. if its a cog belt then it will make a shuddering noise as the drive gear slips over the cogs .. the belt tension is adjustable .. it just wants to be snug not tight, not loose ..

Machine jammed my lock 644D

Undo the needle/s at the holder screw in needle arm and gently manouver any fabric out of the way ... enough to access the screw holding the needleplate on.....very gently try to loosen & remove the needle, needleplate and fabric in one bunch.........cut threads a few inches from the jam and try to ease the whole jam away from the needles and looper, you can then sort that mess out later........

During all these processes, Do Not pull or force anything as you may bend something or throw the timing out (if it is not already out)

Once all is clear, replace only the R needle at this stage and very slowly rotate the handwheel towards you and watch the motion carefully to ensure that there are no drastic collisions of loopers and needle.

If all appears well, re-thread and do a sample test.

If things are not so rosy, you may contact me via the "contact us" page at and I shall see what can be done for you to reset the timing and clearances.......if you feel up to the challenge.
