Last year I pulled a used but well-preserved Butler Airdraulic ashore. The part stood around at a forwarding company and was apparently NOT used. After I removed the resins of the piston rods of the pneumatic cylinders with oil, I quickly realized that the air motor rotates much too slowly. Sounds like a sniffing steam lock. At work we have an identical machine, which I use as a ref. Both machines were operated with 10 bar pressure (compressor boiler is sufficiently large, attached compressor has more than enough steam to supply pressure). My suspicion is that there may also be resins in the air engine, which I can only fix by disassembly and possibly replacement of the sealing rings of the pistons in it. Also the connection for the air supply of the engine seems leaking. Here I have to look at the temperature. h attack. Unfortunately, the web gives only an incomplete manual in PDF form and otherwise no specific information about these machines. Can someone help me here from his experience or with other information? Also by PN. Thank you very much! Greeting Thomas
