STIHL Chain Saw MS180

The average weight of a chainsaw is between 10 to 15 lbs. Some of the smaller electric chainsaws can weigh just 6 lbs while some of the larger and more powerful gas operated chainsaws can even exceed 20 lbs. As you can see the weight of a chainsaw can vary a lot.Chainsaws use a centrifugal clutch, which automatically engages when the engine spins at high speed (when the saw is actually chopping wood) and disengages when it's running more slowly (idling, in other words). A centrifugal clutch is really simple and consists of just a few parts.
