Bar And Chain Combinations; Saw Chain Filing And File Gauges - Husqvarna 440 e-series Owner's Manual

Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvarna chain saw models 440e TrioBrake and 445e
TrioBrake. 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 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 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 440e TrioBrake and 445e TrioBrake 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
440e TrioBrake and 445e TrioBrake. Other chain saw models may not meet the kickback requirements when equipped
with the listed bar and chain combinations.
