The inertia chain brake is a very important safety feature of the modern chain saw. Since kickback occurs suddenly and with great force most people cannot react fast enough to activate the chain brake manually. The chainsaw brake handle, brake spring, and band are designed to be of the perfect weight and tension to activate at kickback by the rapid movement of the saw.
Chain Brake: Located on the top handle of the chainsaw, the chain brake is used to stop the chainsaw chain from rotating around the bar. Always start your chainsaw with the chain brake engaged so the chain does not move. The STIHL Quickstop® chain brake is designed to stop the rotation of the chain if activated by the operator’s hand or by inertia if the saw kicks back with sufficient force.
Starting a chainsaw can be somewhat of a challenge for some and, depending on the temperature outside, on the make and model of the chain saw and the maintenance history and condition of the saw, starting can require some patience. Continue pulling the chainsaw starter until the engine starts. Once the chainsaw has started, hit the throttle once and then release to make the engine speed idle.

Carburetor Idle Adjustment The most probable – and easiest to fix – cause of chain rotation while the chainsaw engine idles is a poorly adjusted idle setting on the carburetor. The result is that too much fuel is delivered to the combustion chamber when the throttle is released, and the engine doesn’t really slow.
