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: An Additional Chain Braking Feature

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.

Front hand guard

The front hand guard can be 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.

throttle lockout lever

The large throttle lockout lever activates the additional chain braking feature. The right hand must be completely removed from the rear handle. This feature is designed to stop the chain within one second.

Coast-down Brake

Only on electric chainsaws. An additional electrically controlled braking device is designed to stop the rotating chain when the trigger is released

WARNING: No chain brake eliminates all risk of kickback injury.

WARNING FOR CORDED-ELECTRIC USERS! STIHL recommends that leg protection be worn when operating corded electric chainsaws. However, the fibers may not stop the sprocket on most corded electric chainsaws because of the constant high torque.

IMPORTANT SAFETY INFORMATION The occurrence called “kickback” can cause serious or fatal injury. Always read the instruction manual carefully before using your saw. STIHL uses a green and yellow color-coding system to help you select a powerhead, bar and chain combination that complies with the kickback requirements of ANSI Standard B175.1 (gasoline-powered saws) and §30 of UL 1662/ ANSI Standard B175.1 (electric chainsaws). Ask your STIHL dealer about safe operating procedures and the advantages of the STIHL Quickstop® chain brake, STIHL Quickstop® Plus additional chain braking feature, STIHL reduced kickback bars and STIHL low-kickback saw chains.

STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.

WARNING FOR ELECTRIC CHAINSAW USERS!
The fibers will not stop the sprocket on most electric chainsaws because of their constant high torque.
