Let it warm up and cool down and I’d suggest not running the compressor to the 300 bar maximum. Stop at about 4000 psi and it will last a lot longer. I had one and probably over worked it. AOA was great about repairing it but when it was returned I sold it went to nitrogen found that to be a hassle and am now using a Alkin 31. I did it the expensive way. If you respect that unit and realize it’s not a continuous duty rated machine it will be fine. Depending on how many friends you have you might need ti consider that aspect of it as well.
