What is the primary purpose of a chainsaw chain brake?

To increase the speed of cutting

To protect the user from kickback

The primary purpose of a chainsaw chain brake is to protect the user from kickback. Kickback occurs when the tip of the chainsaw bar comes into contact with an object or when the chain binds in the cut, causing the saw to jerk back towards the operator. The chain brake is a critical safety feature that can instantly stop the movement of the chain in the event of kickback, thus reducing the risk of serious injuries to the user.

This feature is especially important in wildland firefighting and other scenarios where operators may be working in hazardous conditions. Safety guidelines emphasize the importance of using a chainsaw with an effective chain brake as part of overall safety practices. Understanding this function helps users to operate their chainsaws more safely and effectively.
