What is the first step in the procedure for removing a trapped saw?

Switching off the engine and/or applying the chain brake is the correct first step in the procedure for removing a trapped saw. This action is crucial for ensuring the safety of the operator. When a chainsaw is trapped, if the engine remains running, there is a high risk of the saw losing control and causing injury upon release. By switching off the engine, the operator eliminates the risk of accidental activation during the removal process. Additionally, engaging the chain brake prevents the chain from moving, providing an extra layer of safety while handling the saw. This procedure aligns with best practices in chainsaw operation and maintenance, which prioritize the safety of the user above all else.
