English 1. STIHL Quickstop Chain Brake 6 Kickback and Other Reactive Forces Quickstop chain brake will reduce this protection and also disable the chain brake, increasing the risk of kickback injury. - Never operate your saw without a properly functioning front hand guard. If the front hand guard is missing, manual activation and inertia activation of the chain brake will be completely disabled. - Never attempt to remove, modify or disable the front hand guard or any other component of the chain brake. ■ 0000-GXX-4568-A0 0000-GXX-4119-A0 There are two mechanisms for activating the chain brake if it is in a properly maintained condition: - Manual Activation: If a kickback occurs, the chain saw moves upwards toward the user in a rotating motion around the front handle. The brake is designed to engage if the left hand contacts the front hand guard, which is the activation lever for the brake, and pushes it forward. - Inertia Activation: All STIHL chain saws are equipped with an inertia Quickstop chain brake. If the kickback impulse is strong enough, this alone is sufficient to engage the brake even without contacting the front hand guard. WARNING ■ To reduce the risk of kickback injury: - Never use a saw if the chain brake does not function properly. - When in doubt, take the saw to an authorized STIHL servicing dealer for inspection and/or repair. - Do not use the saw until the problem has been corrected. ■ In a kickback situation, the front hand guard helps protect your left hand from contacting the chain. Removal of the front hand guard on a chain saw equipped with a ■ No Quickstop chain brake or other chain brake device prevents kickback. These devices are designed to reduce the risk of injury, if activated, in certain kickback situations. To reduce the risk of severe personal injury or death from kickback: - Always follow the instructions in this manual and follow good working technique. For example, position your body clear of the cutting attachment whenever the engine is running. Stand to the left of the cut while bucking, outside of the cutting plane, see chapter "Holding and Controlling the Chain Saw", @ 5.6.3. - Maintain as much distance as possible, and never less than 45 degrees, between the bar and your body to ensure that the Quickstop chain brake has sufficient time to activate and stop the chain before reaching any part of your body. - Follow the other precautions provided in chapter @ 8. 22 0458-787-8621-A
