Which device is described as capable of stopping the chain in fractions of a second?

• A. Ematic Bar Lubrication System
• B. Saw Tear Down
• C. Brake caliper
• D. STIHL Quickstop Chain Brake

Answer: (D)

The main concept is rapid chain stoppage through a dedicated brake system. On a chainsaw, a brake mechanism is designed to halt the chain as quickly as possible to prevent injury from kickback. It works by engaging a friction surface against the clutch drum, snapping the sprocket and chain to a stop in fractions of a second. The device that embodies this rapid-stop function on STIHL saws is the STIHL Quickstop Chain Brake. It’s specifically built to arrest chain motion almost instantly when activated, which is exactly what the question is asking about. The other options relate to lubrication, maintenance, or generic braking hardware and do not describe the fast-acting chain-stopping device.
