STIHL chainsaws come equipped with a STIHL Quickstop® chain brake designed to reduce the risk of injury in certain kickback situations. Some chainsaw models have STIHL Quickstop® Plus, an additional braking feature.
When handguard is in forward position, brake band is engaged.
When front handguard is in the rearward position, brake band is disengaged.
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 also 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.

Only on electric chainsaws. An additional electrically controlled braking device to stop the rotating chain when the trigger is released.
WARNING: No chain brake eliminates all risk of kickback injury.
