A chainsaw engine runs all the time, but you don’t want the chain spinning unless you’re actually cutting wood, like using it as a brush cutter machine: that’s dangerous and it wastes energy. The clutch solves this problem. As explained in more detail below, the centrifugal clutch connects the engine and the chain when the engine speed is fast (when the operator pulls on the throttle) and stops the chain from spinning when the engine speed is low (when the chainsaw is just idling).
