Review on Valianto Grinder Pneumatic Polishing Engraver by Carta Gutierrez

I haven't used it yet because the instructions are so bad I can't figure out how to assemble it. Came with an empty bottle for oil I guess hmm where do I put the oil? How do I put sharpening points in a pencil grip? Why do you need another nozzle? I can't even find a video with instructions on YouTube. Disappointing! Well understood, but the problem is, use two wrenches, turn the collet and the hole in the cover in opposite directions. The rear triangle holder slipped off the tube, it didn't have a screw to hold it. After using the tool for 15-20 minutes, it got too hot to handle, so back to the oil issue, which one and where to apply it? Love the way it grinds, just wish the company had put a little time and effort into the instructions, now I'm missing a screw, a loose bottom cap and a tool that needs oil (where and what).
