A lock washer maintains tension on its fastener so it won’t back off as the machine runs and vibrates. Because the brush-head hardware is common across the CV/CVD line, this washer fits a wide range of Tornado uprights.
Replace the lock washer if it is flattened, cracked, or corroded, or has lost its spring tension so it no longer keeps its fastener tight.
