Take it back.

Search for: sewing machine timing Lots of web sites and videos available.

Take it back to the Dealer.( He probably has a guarantee on the work he did). Let him show you how it works. If he won't do this then it is definitely time to find a more reputable dealer. If you paid for a repair it should have been repaired.

it may be that your motor belt needs tighening or the belt may be damaged - you can check belt and adjust tension yourself once side cover is removed.

if you are sewing thick seams and the needle is resting on the seam as you begin to sew you may have to help the machine to get started. if the fabric is not thick it must be belt tension.

there is a video on utube showing how. Spinktor.

I would suggest that you call pfaff because if you do not have a pfaff dealer where you live then you will have to pack it up and ship it to a pfaff dealer that is near to you. Good luck oh and make sure to insure it. Hope that helps

That machine does not have a chain in it. It does have 2 belts a motor belt and a timing belt. Bolth belts very rarely brake. What are the machine symptoms, it may not be a belt at all?

Here's a manual for your machine. http://s2.vsmgroup.com/VSM/Pfaff/pfaffmanual.nsf/1fd5659e6f37141041256697003e64c0/8fa2fdee7a0f682f852575fb006e0f28/$FILE/Pfaff%204240-4250-4260%20Hobby%20X%20.PDF

it should be a silver lever on the back side on the left of the machine. it sticks out so it pretty easy to see,,it's called the presser foot lever

This is generally caused by either the needle being inserted backwards or by the needle being bent. It may not look bent, but be ever so slightly bent that you can't even see it with your eye.

The best thing to do is to change your needle, make sure you are inserting it with the flat side facing away from you in the shaft. See if this doesn't solve your problem. Good luck!

which make and model do you have?

Sounds like a threading problem. Thread the machine all the way to the needle but not the needle eye. Then pull on the thread and lift the presser foot up and down. You should have tension when it is down and no tension when it is up. If this is the case try sewing, should fix the problem. If this is not the case your machine will need to be adjusted buy your pfaff dealer.
Hope this helps

I believe that you have it already figured out. The tension is going to be the problem. Try adjusting the tension, just try different settings.

it will not sew

you might try sewusa.com they have threading diagrams

I had the same problem. the last resort was go get a professional repair person. i had to replace the whole needle shaft. then the tension feeds were looked and i have never been more satisfied.
