<p>[QUOTE=&quot;GDJMSP, post: 2572596, member: 112&quot;]Short and sweet it comes from the machines - the only place it CAN come from. You also have to realize that &quot;grease&quot; as in &quot;struck through grease&quot; is a generic term. I really don&#039;t know what kind of lubricant the presses have in them, on their parts. But they most definitely have a lubricant just as any and all hydraulic machines do. And in my lifetime I&#039;ve been around a whole lot of hydraulic machines, from the smallest you can think of to the NASA crawler you talked about - and I mean up next to it - on it even. And every single one of them, if you touched one of the hydraulic pistons with your hand or fingers, regardless of what kind of seals they have on them, you will absolutely get &quot;grease&quot; on your fingers.</p><p><br /></p><p>That&#039;s where the grease comes from.[/QUOTE]</p><p><br /></p>
