HELP PLS. pfaff serger, hobbylock 788. it has been working fine. today i cant turn it on at all. what could be the problem?

Pfaff has the manual for the Hobbylock 796 on their site, http://www.pfaff.com/Support-and-Updates/Support . Use the drop-down menu to find the Hobbylock. The current link to the manual is http://www.pfaff.com/SiteMedia/PFAFF/Products/Machines/Support-manuals/Hobbylock_794_796-manual-EN.PDF . See pages 7 - 11 for the threading diagrams for a 4-thread double overedge seam. See page 17 for the changes needed for a 3-thread seam. One of the generic threading videos for sergers may help: https://www.youtube.com/watch?v=MrqHC2CNjVI . There's also one for the Pfaff Hobbylock 786: https://www.youtube.com/watch?v=cOZ-djsXdhQ .

I hope these help.

Pfaff has a video on threading the Hobbylock 4842 here: http://www.pfaff.com/mediafiles/threading_guide/index_en.html . You need Adobe Flash Player available on your browser. Enter the tutorial, the link is below the Quick Help paragraph. Then choose the correct machine (from the links across the top). Then use the drop-down menu to choose the stitch that you will be sewing for the appropriate threading video. Then click on the appropriate thread (below the video window) to see how to thread that section of the serger. (For two-thread stitches, you will see two options are greyed out.)

I hope this helps.

However, if it is a used machine, so much is subjective based on physical and operating condition, the accessories included, desirability of the model, where it is located, etc.

Do you frequently oil your serger? Sergers require more frequent oiling and cleaning than sewing machines to keep them going. Be sure to use the correct oil for your machine.

It could have some threads wrapped somewhere that is keeping the machine from operating.

The other problem could be that it is out of time. If so, take it for service.

Hi,
I have the same problem, thee needle holder shaft swirls from left to right, is very loose. Maybe there is a screw missing, but which one? Please look at the pictures.

The hobbylocks all thread in much the same fashion.  There is a diagram for a four thread hobbylock on this website.  It would be better if you found a Pfaff dealer to show you as it is quite complicated.

Once you have it threaded, always cut the old threads at the spool and knot new ones on and pull through.  You will have to thread the needles as the knots will not pass through but it does save an awful lot of frustration when needing new colours on the spools.

Does it still make noise? Maybe it needs a new belt or just some oil?

Do you know the looper threader broken can be repair by yourself? I suggest you to order the following product:
