I have a funlock 004D/004, the lower looped broke and I replaced it with one I ordered online. It makes a chain when I run it but when I try to sew fabric nothing catches. Any suggestions?

you have to make sure the looper is properly positioned. With the screw loosened slightly you should be able to move the looper up and down slightly, thus adjusting the timing. You are looking for the lower looper tip to come in slightly above the needle eyes, as close as possible without touching. Then the upper looper must come in right behind the lower looper "head" as close as possible without touching. The upper looper should then extend past the left needle by about 2-2.5mm, and the needles will come down before the eye of the upper looper returns to the right.

Thread broke on bottom looper the first time out of box i had to try and thread and the tension was still tight The bottom threads were not stiching

I'm going to assume here you're talking about a serger. Unthread the lower looper and the eyes of the needle. Set the lower looper tension to 0. Rethread the lower looper, then the needle eyes. Then reset the lower looper tension (try about half a number lower) and see if it chains. If it won't chain, try replacing the needles.

Fix timing on juki

Don't forget there is a "hidden" threading phole all the to left side of lower looper before it gets threaded front to back in the threading hole on horizontal lower looper that is visible looking at machine head on.
Hope this helps.

I have a coverstitch PF857 and I have broken the upper over edge looper I have sent for the spare part but been told it must be set what does this mean and how do I do this

There are many adjustments which can be made: up, down, twist right or left, slide front or back. The main question is why did the looper break? The needlebar, upper and lower looper and the needle guard all must be in perfect syncronization. The upper looper must be set so that, on its movement to the right, ever so slightly brushes the needles. Then, as it travels upward, it must cross behind the lower looper at just the right spot as close as possible without touching. If you are very mechanically inclined, give it a shot. If not, the risk of further damage is high.

Lower looper needle broke

 Well, first of all, while it might be possible, I highly doubt it.
More then likely the timing is off. There are several adjustments that need to be made correctly or you will end up with more problems. Your best bet is to take it to a qualified service technician.
