Which of the following is a feature of the STIHL Quickstop Chain Brake?

• A. Increases chain tension
• B. Must be replaced after every use
• C. Is designed to stop the chain in fractions of a second
• D. Requires daily calibration

Answer: (C)

The main idea here is safety through rapid chain stoppage. The STIHL Quickstop Chain Brake is built to halt the chain in fractions of a second by engaging a brake band against the clutch drum when the front hand guard is moved. This quick stop is crucial for reducing the risk of injury during kickback, giving you immediate control of the saw. It doesn’t affect chain tension—tension is handled by the tensioning mechanism—nor does it need daily calibration or replacement after every use. So the standout feature is its design to stop the chain extremely quickly for safer operation.
