Husqvarna 550 XP G Owners Manual - Page 38

TECHNICAL DATA Recommended cutting equipment for USA Following is a list of recommended cutting equipment for the Husqvarna chain saw models 545, 545 TrioBrake, 550XP, 550XP TrioBrake, 550XPG and 550XPG TrioBrake. The combinations of power head, bar and chain have been investigated in accordance with the kickback and vibration requirements of ANSI B175.1-2000. The guide bar nose radius is determined by either the maximum number of teeth in the nose sprocket or the corresponding maximum nose radius of a solid bar. The following list is the chainsaw manufacturers recommendations. There may be other combinations available, which will also achieve kickback reduction. As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius than in our list. For guide bars of the same length, all sprocket-nose guide bars of the same pitch and having the same number of sprocket teeth may be considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar may be considered to have equivalent or less kickback energy than the sprocket-nose bar. Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B175.1 safety requirements for gasoline powered chain saws when tested on the representative sample of chain saws below 3.8 cu. in. specified in ANSI B175.1. We recommend that you as a replacement use the listed chains or "Low kickback saw chains" which are available at your dealer. Saw chain Husqvarna H30 is listed as a "Low kickback saw chain". The following cutting attachments are approved for the models Husqvarna 545, 545 TrioBrake, 550XP, 550XP TrioBrake, 550XPG and 550XPG TrioBrake.
