Tighten by rotating Ridged Base clockwise. Cleaning epoxy from your machine: Scrape as much material as you can from the surface using a stiff metal or plastic scraper. Clean the residue with lacquer thinner, acetone, or rubbing alcohol (follow safety warnings on solvents, and provide adequate ventilation). Once epoxy is removed, use a clean, wet cloth to remove any remaining solvents from the surface to avoid damaging, stripping or corroding the machine or arm. Troubleshooting: If rotating arm falls off, be sure to tighten before each use and check occasionally while the arm is rotating to ensure the arm is secure. Additionally, prop up the end of the base opposite the motor housing to counteract gravity and keep the arm from unscrewing. If medium is sliding to either end of cup, prop up corresponding end of Base to even out pooling.
