once you run an oiler on air gear, NEVER run the machine dry again.
as was stated, the oil will wash away the lubricants in the cylinders and solenoids...
if you run it dry, you risk blowing the seals and causing yourself a really expensive repair.
That is completely correct. Oil-less systems like on the new Challenger III do not require oil and have an oil separator at the input to the air to eliminate even compressor oil from entering the system. Once oil is in the system you should not run the press for a long period of time without oil in the oilier. I would be also curious to see the oilier stated that failed to see why it is not working. I personally have not seen an oilier that did not work unless contaminated air was putting rust particles or something like that into the unit.
I'm glad I brought this up. It did sound kind of strange to me not having to use the airline lubricator.
I will check tomorrow if daring it of the oil and refilling it has made any difference.
What is considered a long period of time for running the machine without oil? Got lots of work to do next week on that press. And I'm not sure for how long this is already broken. I think we last refilled the oil a month ago.
