STIHL Quickstop® Chain Brake
STIHL chain saws are equipped with a chain stopping system designed to reduce the risk of injury in certain kickback situations. It is called a STIHL Quickstop® chain brake. 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. In some working positions, the STIHL Quickstop® chain brake can be activated by inertia, stopping the chain within fractions of a second.
STIHL Second Chain Braking System (Q)*
STIHL also offers a second additional, manually-activated chain brake on some models. This system is designed to engage when the operator’s right hand completely releases the rear handle, stopping the chain within one second. Available on some models.
*WARNING: No chain brake eliminates all risk of kickback injury.
1. Front hand guard activated
either by manual movement of the hand guard forward
or by inertia if there is sufficient force in
the kickback. This system is designed to stop
the chain within a fraction of a second.

2. The large throttle interlock
lever activates the second brake system. The right
hand must be completely removed from the rear
handle. This system is designed to stop the chain
within one second.
