They can be classified into two main categories i.e. gas-powered chainsaws and battery-powered chainsaws. The mostly widely used chainsaws are the gas –powered ones because they are more powerful than battery powered however, they have more drawbacks. For example, they are noisier and environment unfriendly since they emit dangerous fumes when operating.

Most chainsaw accidents are caused by the kicks back. Normally, kickback occurs when the upper tip of the chain bar encounters something to cut making the bar tip to go upwards and the saw gets thrown backwards towards the operator because of the rotating chain force.
The only way of avoiding kickback is by ensuring the bar tip does not encounter the material your cutting. However,sometimes kickback happens when saw operator is not aware and that why most saws have chain brake safety feature. Chain brake can stop kickback in seconds before you areinjured. It is mostly activated by either wrist or saw motion during kickback.
Another chainsaw safety feature is chain catcher and it helps in preventing the chain from being thrownbackwards towards the person operating the saw.

Mostly, all chain catchers are made using aluminum so that they cannot damage the chain.
To prevent the chain from rotating in case the trigger is pressedaccidentally. Thethrottle helps in preventing hot starting while the saw is still on the floor and your leg inside the handle.
On and off switch/Kill Switch
