Which statement best characterizes the Quickstop Chain Brake’s activation?

• A. It requires no user input
• B. It is activated only by the engine RPM
• C. It cools the chain after braking
• D. It can be manually activated or activated by inertia

Answer: (D)

The statement reflects how the Quickstop Chain Brake is designed to engage: it stops the chain quickly and can be activated in two ways—manually by the operator and automatically by inertia. You can trigger it by pushing the front hand guard forward or otherwise activating the brake, and it can also engage if a kickback causes the guard to move, pulling the brake into place. This dual capability is what makes it the best description, since activation isn’t limited to a single input or to engine behavior. It isn’t about engine RPM, and it doesn’t cool the chain after braking.
