Made by metal die-casting with high-strength return springs for stable and durable structure. At idle speed, the clutch shoes remain separated and the chain stays stationary. When engine speed rises, centrifugal force pushes shoes against clutch drum to drive sprocket and saw chain.

Common failures include spring fatigue, shoe wear and slipping, resulting in weak chain power or chain not rotating under load. Standard size enables simple installation, suitable for maintenance of domestic 4500, 5200, 5800 gasoline chainsaws.
