Pro Installation Tip for Best Performance

Before installing your new belts, it is critical to thoroughly clean the entire belt path surface (pulleys and flywheels).

• Use isopropyl alcohol (rubbing alcohol) and a cotton swab to remove old, invisible rubber residue.
• Failing to clean the path can contaminate the new rubber, leading to premature slippage and reduced lifespan.
