Hi Erik,

Like you, I did not know much about these machines. I did find a lot of info online. My machine was used by the US military so they had documents online about how to service it, etc. Things like the engine are often used in other application so you can research what type of engine it has and then search for that specifically. I my case the engine in my machine was often used for welders.

There are also so excellent folks here with knowledge so you may luck out. The more specific the question, the more specific the help.

Good luck!
