English / USA ANSI B 175.1-2000 chainsaw kickback standard Section 5.11 of ANSI standard B 175.1-2000, sets certain performance and design criteria related to chainsaw kickback, which has been adopted for electric chain saws in UL 16 62 in section 30. To comply with kickback § 30 of UL 16 62 electric chain saws: - 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. The computer derived angles for electric saws are measured by applying a computer program to test results from the 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 automatic-ally mean that in a real life kickback the bar and chain will rotate at most 45°. !Warning! In order for electric chainsaws to comply with the computed kickback angle requirements of § 30 of UL 16 62 / § 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 Owner's 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 power-head with green labeled reduced kickback bars and low kickback chains. !Warning! To reduce the risk of injury, stop using the saw immediately if the chain brake does not function properly. Take the saw to your local STIHL Service Center! Do not use the saw until the problem has been rectified (see the section "Chain Brake"). 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. The Quickstop is available as standard equipment on your STIHL chainsaw and is available for installation on most older STIHL saws. Ask your dealer to retrofit your older model saw with a chain brake. MSE 140 C, MSE 160 C, MSE 180 C, MSE 200 C 13
