I just bought this compressor and am looking for a bit a information. It looks to be in great shape for it's age (1973) and appeared to be well cared for. I purchased it from a Mako dealer who just used it occasionally to fill some tanks. They ran it for me before I purchased it and it quickly built to 3200 and shut down. They state it can only pump to 3200 with the current setup. It has filtration and auto drains installed. They said the 4th stage was just rebuilt, fresh oil change, and 25hrs on the filter. The unit has around 2600hrs on it. I was wondering if anyone had any maintenance information or manuals for this compressor. Also, it came with a 6 month warranty, so is there anything I could check to possibly catch any problems that may need attention now. Any help that you may have would be greatly appreciated. Thanks Mike
