As before, the chain brake can be activated by the inertia of the front hand guard in certain kickback situations or manually by pushing the front hand guard toward the bar nose. In both of these cases the brake, once activated, is designed to bring the chain to a standstill within fractions of a second. In addition, there is a secondary system (STIHL Quickstop Plus) that is designed to stop chain rotation within a second of the operator fully releasing the rear handle. The locked chain is not released again until you press down the throttle trigger lockout to operate the throttle. The chain brake can be activated in three ways: 3 Manually by fully releasing the rear handle, including the throttle trigger and throttle trigger lockout. To reduce the risk of personal injury or property damage during cutting, observe the characteristics that make this saw different from saws not equipped with a STIHL Quickstop Plus chain brake system. Before operating the chain saw for the first time, make sure you are familiar with how the rear-handle activation works. Pay special attention to the chapter “Chain Brake. ” 2 1 150BA000 KN The activating mechanism for the STIHL Quickstop Plus chain brake system is integrated in the throttle trigger lockout (rear handle). One of the big advantages of this system is that the saw chain is automatically locked in position when carrying the running saw by the front handle (with the rear handle fully released). 1 2 By inertia in certain kickback situations Manually via the front hand guard 2 MS 261 C-Q English Guide to Using this Manual Pictograms The meanings of the pictograms attached to or embossed on the machine are explained in this manual.
