You should take it for service. It could be slightly out of time.

Often not a DIY job, as there are usually a number of other adjustments to be made. If you really want to DIY, talk to the nice folks at the yahoo group "wefixit": https://groups.yahoo.com/neo/groups/wefixit/info who can walk you through it.

Jeff: First it is never wise to put your email address in a public place like this. Second... your pictures didn't come up. I suspect you have a shim... but not being able to see the pictures. It's hard to advise you.

Unfortunately you'll only find the diagrams in the user's manual, and as it's copyright material it's against International Laws and against FixYa's terms and conditions for me to simply scan and upload them.

The information is not available in the public domain either, so you'll have to buy a new manual as either a download or a hard copy. You'll find a hard copy to buy here, but there are other suppliers. A downloadable version is available here at a lower cost.

If you can do without the diagram then most Necchi models are similar with respect to threading, so these free instructions may help or these videos (for different models) may be of use.

Sheila,
I called the company which sells Necchi Machines and parts(Allyn)
in the States about the belts.Their Number is 800-525-9987. The parts department says Necchi used several different motors with differing motor mounts which means there is no standard motor belt for this model machine. The only way to get the right belt is to either take in the machine or the old belt to your repairman. More than likely he will have a Generic belt which will work.

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

The most common reason is the needle not inserted correctly (backwards), other causes can be burrs on the needle plate opening or burrs on the parts in the bobbin area.

What you really need is manual - unfortunately I cannot find a free one but here is a link to one you can buy ($14.99) :-

It is a foot that has a small square hole on the bottom that goes up and down with the needle.

If your stitches do not look good on the top side you have a problem with the bottom thread. make sure you have the correct bottom tension: Is the thread under the bobbin tension plate and when you hold the bobbin and case lightly in your hand the tension should be set in a way that there is little resistance , yet still some, when you pull the thread. After you set your bobbin tension, you may have to adjust your top tension to balance. Also make sure the thread comes off of your bobbin the way your manual tells you, clock or counter clock wise.
Make sure your bobbin (plastic) is not sooooo old, buy a new one.

You can find your manual @ the Necchi distributer (it is a copy of your original) @ 1-800-525-9987. Mine cost $14.25- Shipping & Handling, included. Also, they let yu download or get a copy of your manual (or sent on a CD), if it is listed where the Necchi's are listed ( in order of first letter of your brand). I ordered mine from the distributer.

Instructions normally come via the manual, but you might find a sewing club. https://www.google.com/search?q=Necchi+4825+manual https://www.google.com/search?q=Necchi+sewing+club+near+me ..
