H L 0012BA022 KN English - must, in their original condition, meet a 45° computer-derived kickback angle when equipped with certain cutting attachments, - and must be equipped with at least two devices to reduce the risk of kickback injury, such as a chain brake, low kickback chain, reduced kickback bar, etc. b) Saws with a displacement of 3.8 cubic inches (62 cm³) and above - must be equipped with at least one device designed to reduce the risk of kickback injury, such as a chain brake, low kickback chain, reduced kickback bar, etc. The computer-derived angles for saws below 3.8 cubic inches (62 cm³) displacement are measured by applying a computer program to test results from a kickback test machine. Warning! The computer-derived angles of § 5.11 of ANSI B 175.1-2000 may bear no relationship to actual kickback bar rotation angles that may occur in real life cutting situations. In addition, features designed to reduce kickback injuries may lose some of their effectiveness when they are no longer in their original condition, especially if they have been improperly maintained. Compliance with § 5.11 of ANSI B 175.1-2000 does not automatically mean that in a real life kickback the bar and chain will rotate at most 45°. Warning! In order for powerheads below 3.8 cubic inches (62 cm³) displacement to comply with the computed kickback angle requirements of § 5.11 of ANSI B 175.1-2000 use only the following cutting attachments: - bar and chain combinations listed as complying in the "Specifications" section of the instruction manual or - other replacement bar and chain combinations marked in accordance with the standard for use on the powerhead or - replacement chain designated "low kickback saw chain". See the section on "Low kickback saw chain and reduced kickback bars". Devices for Reducing the Risk of Kickback Injury STIHL recommends the use of the STIHL Quickstop chain brake on your powerhead with green labeled reduced kickback bars and low kickback chains. Warning! To reduce the risk of injury, never use a saw if the chain brake does not function properly. Take the saw to your local STIHL servicing dealer. Do not use the saw until the problem has been rectified. STIHL Quickstop Chain Brake STIHL has developed a chain stopping system designed to reduce the risk of injury in certain kickback situations. It is called a Quickstop chain brake. All STIHL chain saws are equipped with a Quickstop chain brake which can be activated by inertia. If the forces of an occurring kickback are sufficiently high, the hand guard is accelerated towards the bar nose even without hand contact. See the chapter entitled "Chain Brake" of your instruction manual. Warning! Never operate your chain saw without a front hand guard. In a kickback situation this guard helps protect your left hand and other parts of your body. In addition, removal of the hand guard on a saw equipped with a Quickstop chain brake will deactivate the chain brake. 14 MS 192 T, MS 192 TC
