Worked great for years without any issues and still currently technically runs but Old reliable finally decided to loose pressure when it wants. That is the issues it's having, runs and works well then looses pressure. For the work we are doing we need something without issues so we bought new. If someone wants or has time to tinker with it, it's for sale. It does turn on and run but occasionally looses pressure and doesn't want to build pressure. Buying as is where is, as a non operable machine. I can turn it on for you and run it if needed, I think all it needs is a rebuild kit. It is a complete unit. Was going to use it for parts since it's at least worth that in parts but will part it out if no one wants it
