When I did my first Mdoel 33 (an ASR, in a Data Dynamics 390 cabinet), I compleely stripped it, cleaned very part, and reassembled it. It didn;t work the fiurst tiem, I'd mies-assembled the linkage that auppresses printing on control characeters. On the otehr hand my excuse is that I didn't have the manauals, and was doing everythign by intuition... I wouldn;t even turn it over by hand without lubricating it. Perhaps I am over-cautious, but I'd rather not add wear to parts if I can avoid it. I would dismantle it at least partically. That is remveo the carriage, motor and trasmit shaft at least. Clean all the parts you can, then go over the lubrication points. Then turn the machine by ahnd and check everythign seems free and works correctly. Only then apply power. Note that the clutches will not latch up propermy if run and hand-turning speed. Unless you latch them up byy hand or trip them immediately after applying power so that they then latch up properly, you will burn the cluch shoes. As for the puch, take care if you strip this down. I think it's best to keep parts in the origianl order. Yes, the levers are all the same, but like the parts of a car engine, the y'wear into each otehr amd it's best to keep them in sets. Keep the punch pins in the same holes of the die block. Follow the instructions in the manual if you have it. I didn't ahve the manaual nad removed an obvious screw early on. Unfortuantely this releeased the main pivod with the reult that the levers (and IIRC pins) becaame airborne. Don't ask... -tony
