Understand Chainsaw Basics and Chain Brake

What happens here

The Stihl MS 170 chainsaw is introduced as a typical farm saw. The demonstrator explains that the chain brake is a key safety feature. When the saw's tip (kickback zone) hits an object, the chain brake is designed to engage automatically, instantly locking the chain in place to prevent the saw from violently kicking back towards the operator. It's important to understand how to engage (push forward) and disengage (pull back) this lever manually as well.

Goal: This step introduces a small Stihl MS 170 chainsaw and explains the critical function of its chain brake in preventing kickback.
