Because a chainsaw is a high-speed wood-cutting tool, some special safety precautions must be observed as with any other power saw to reduce the risk of personal injury. Careless or improper use may cause serious or even fatal injury. STIHL’s philosophy is to continually improve all of its products. As a result, engineering changes and improvements are made from time-to-time. If the operating characteristics or the appearance of your chainsaw differs from those described in this Manual, please contact your STIHL dealer for information and assistance. STIHl MS 441 C 1 English / USA Secondary Chain Braking System This STIHL chainsaw is equipped with a chain brake system that can be activated in three different ways. 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 that is designed to stop chain rotation within a second of you letting go of the rear handle. The locked chain is not released again until you press down the throttle trigger interlock lever to operate the throttle. The chain brake can be activated in three ways: 2 1 150BA000 KN 1 2 By inertia in certain kickback situations Manually via the front hand guard The activating mechanism for the secondary chain braking system is integrated in the throttle trigger interlock lever (rear handle). One of the big advantages of this system is that the saw chain is automatically locked in position for engine starts and when carrying the running saw by the front handle (with the rear handle released). 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 secondary chain braking system. Before operating the chainsaw for the first time, make sure you are familiar with how the rear-handle activation works. Pay special attention to the chapters “Chain Brake ” and “Starting/Stopping the Engine “. 3 Manually by releasing the rear handle 2 MS 441 C English / USA Guide to Using this Manual Pictograms All the pictograms attached to the machine are shown and explained in this manual.
