If you don't know what you're doing, find or hire somebody that knows crawler loaders, even better if they know similar Case's, if you can't find somebody that knows Case crawlers then a well seasoned operator who knows equipment in general would still be worth the second opinion, even if it's just another set of eyeballs.
