Best left to a gunsmith
The thread I've attached below from TheBoxoTruth.com has a lot of helpful information for all new owners of the TT-33, but I wasn't able to find an original, translated PDF for the operators manual. Sorry, mate. Hope this will suffice.
Search for Tokarev TT33, it's technically the same. Although this is true, there are some important differences. The Yugoslavian M57 holds one more round in the magazine for a total of 9 in the mag. The T33 holds 7. Also during dis-assembly the barrel is removed differently, being pulled up and back out of the slide, whereas the T33 is removed from the front of the slide.
