20 Most Recent Necchi 4575 Mechanical Sewing Machine - Page 3 Questions & Answers

There could be a simple solution or one that needs professional assistance, try inserting a new needle with making sure that the flat side is facing away from you. Also, try a light sanding in the hole that the thread comes through. Try rethreading with different thread and making sure that you leave enough of a tail on the bobbin thread. If, this does not work you may need to have the timing checked. good luck

Hello,

Make sure you clean all the broken thread out of the bobbin area first. It sounds like you knocked the timing out when the thread knotted up. Look in your machines manual on the procedure to re-engage the timing. It will probably be a push this button in while turning the hand wheel until you feel the clutch re-engage, type of procedure.

Good Luck!

I have a necchi sewing machine, my operation manual has a picture of how to thread the machine, it might help you figure out how to thread your they should be simular,,I tryed to up load the picture & couldn't,, if you would send me your email address I will send you the picture

you might try checking your needle to see if it's bent-roll on flat surface to see if it roll correctly
or blunt or damaged
some sewing machines bunch up like that when the thread come off the thread take up lever
also check the top tension
check for lint or loose thread in the bobbin area
check to make sure the bobbin is wound correctly

make sure the sewing machine is turned off first
the flat side of the shaft of the needle goes toward the back of the machine
insert the needle as far up as it will go

try some of these solutions
check your upper thread tension number & see what it's on
the higher the number the tighter the tension
the lower the number the looser the tension
try rethreading the machine
check to make sure you have the right size needle for the fabric
check to make sure your needle is inserted in the needle clamp correctly(the flat side toward the back)
check to see if the needle is bent-roll it on a flat surface to see if it rolls correctly
if it's blunt-it makes a popping sound when going into the fabric

Hi. Interesting problem. For outdoor materials (and advise on sewing on outdoor materials) I rely on Sailrite (http://www.sailrite.com/) and interestingly, couldn't find Weathermax fabric on their site. I would contact their forum (http://forum.sailrite.com/) and ask the question there. Matt Grant (I think he runs the sewing part of the forum) is extremely knowledgeable and helpful.

Sorry I don't have anything more for you,

There is a screw on the bobbin case to adjust if you have too, the thread should pull through with slight resistence, if it is too loose tighten the screw a quarter of a turn at a time clockwise and test and keep adjusting if you have to.

try these things
1.needle inserted into holder wrong
2.needle may be bent
3.wrong needle in machine
4.size of needle & thread not compatible

Top tension about 4 or 5 makse sure you have the bobbin in the correct way round and make sure you can just pull the thread through with slight resistence.

This seller has one - http://cgi.ebay.com/Simplicity-Foot-Control-Pedal-Sewing-Machine-Serger_W0QQitemZ200351851249QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2ea5e6a2f1

Go through this list to see if one of the models looks like the 4575.

Sometimes a manual serves more than one model.

It is possible that the needle is not installed correctly - this is usually with the flat side facing the back of the machine.

Always thread the top thread with the presser foot up.

Hold onto the thread tail at the needle and (by hand and not with the power pedal) turn the handwheel to lower and raise the bobbin thread.

Take both thread tails under the presser foot and toward the back of the machine before you begin to sew.
