Bar and chain combinations
Chain saw models Husqvarna 445, 445e, 450 and 450e 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,
450 and 450e. Other chain saw models may not meet the kickback requirements when equipped with the listed bar and
chain combinations.
Note: For the saw chains above (if available) you are free to choose between 0,050" or 0,058" gauge drive links for the
corresponding bar, see the table below.
