TECHNICAL DATA Recommended original and replacement bar and chain combinations Following is a list of recommended cutting equipment for the Husqvarna chain saw models 445, 445e, 450e and 450. The combinations of power head, bar and chain have been tested and found to be in accordance with the kickback and vibration requirements of ANSI B 175.1-2000. 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 chain saw 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. Bar and chain combinations Chain saw models Husqvarna 445, 445e, 450e and 450 met the kickback performance requirements of ANSI B 175.1-2000 when tested with the combinations of bars and saw chains listed below. The saw chain Husqvarna H30 is also classified as a low kickback saw chain since it met the requirements for low kickback saw chain outlined in ANSI B 175.1-2000. We recommend to use only the listed combinations of bars and chains for chain saw models Husqvarna 445, 445e, 450e and 450. Other chain saw models may not meet the kickback requirements when equipped with the listed bar and chain combinations.
