Hi Emily,
(I’m a bit cofused, since I don’t think C&P made a 9×13 platen.) The designation comes from the size measured on the inside of the chase. I’m betting it is either a 10×15, or 8×12. Either one is a fine machine, and I’ve owned both and loved them. I’m assuming it is a hand-fed and not automatic, right? OK—oiling it is very important, and in my shop we used to try to oil the press every four or five operating hours, or once a week at least. I found it easy to establish a “route” for oiling, beginning at one spot and going around the press. For example, beginning at the top at the ink fountain, if it is so equipped. No ink fountain? Start at the rear of the ink disc where there are a couple of oil holes for the disc axle. Also, there should be an oil hole for the ratchet arm and end. From there move either direction and wherever you find a hole, fill it with oil. If there are bits that interact against one another, they will need a light coating of oil. The large ring gear and small driving gear on the off-side of the press need grease on occasion. Assuming it is treadle-driven, it’s very important to oil the crank follower arm (between the crankshaft and and the treadle arm), as well as the main bushings for the crank (One on each side of the arm, where it goes through the side-frames of the press.) After you get oil in all the holes you can find, turn the press over a revolution or two and stop in a different position (bed to platen, for example) and see if you can find any more oil holes. Odds are that there will be a couple more holes, hiding out and grinning at your attempts to find them….
I use single-weight 30 or 40 oil, since when these machines were built, there were no multi-grades.
It is very important that the machine is clean, and I suggest following advise already given. You also might ask your roller supply house what they suggest for cleaning your rollers. Oh, and when setting up the machine, begin with a gap between the rollers and the type, and work in toward a nice solid contact. This avoids punching a roller or ruining type.
(I do ramble on….my apologies. I used to teach press operation at our local community college, and I guess one never out-grows the need to explain in painful detail.) How about this: go slowly, follow your instincts, and “when in doubt, back it out!”
Best of luck,
Barb
