STIHL Quickstop®STIHL chainsaws 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 Quickstop® Plus (Q) - an additional chain braking featureSTIHL offers an 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.
