Hi, I ran into this problem on a Brother Serger and if your machine is set-up for four thread overlock, this may help. Set all the tension control knobs to"3". The overlock may seem loose but see if the skipped stitches gets better or worse. Remember that the loopers are just that, they work best when the thread is not pulled tight. I found that if I took the looper tensions back up gradually, I got a pretty nice overlock at about "5" without skipped stiches.

Tough finding any information on this machine. I believe the single cord 3.5mm Brother is what you need but better call them and see what they say.

Brother Brother 760DE 760D 760 730D 730 Overlocker Instruction Manual

If it is a mechanical machine, you can perform more oiling than recommended in the manual. I remove the base of my Bernina overlocker and oil the other moving joints. Even applying heat from a hairdryer may help. Below is the process I use for sewing machines, but it would work on a serger too:

Probably something wrong with bobbin case.
When did you last have this Serviced?

No you cannot, the transformer will work for a while and it will get very hot and cound catch fire. You should get a transformer at least 100 W to 120 W. It can be an auto transformer which is not so bulky as an isolating transformer, but be careful how you wire it up.

Also have look on the machine it self to see how many watts in consumes. The number on the pedal may be the handling capacity of the pedal control.

Looking for the manual for the brother lock-523
