Engaging the chain brake is an essential action before beginning any work with chainsaws in a tree because it serves as a crucial safety measure. The chain brake is designed to stop the chain from rotating when activated, which helps prevent accidental cuts or injuries while preparing to operate the chainsaw or when it is idling. This is particularly important in tree work, where conditions can be unpredictable and the chainsaw might come into contact with a worker or nearby equipment. Ensuring the chain is safely secured allows the operator to work with peace of mind, thus reducing the risk of accidents.

While inspecting surrounding vegetation, measuring tree height, and testing the chainsaw are all important parts of preparing for tree work, they do not specifically address the immediate safety of the operator and others around them in the same critical way as engaging the chain brake does. Safety procedures take precedence, making the activation of the chain brake a fundamental step prior to any chainsaw operation.
