Recommended original and replacement bar and chain combinations
The following cutting attachments are approved for the model Husqvarna 455e-series Rancher 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.
Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B 175.1 safety
requirements for gasoline powered chain saws when tested on the representative sample of chain saws below 3.8 cu.
in. specified in ANSI 175.1. We recommend that you as a replacement use the listed chains or "Low kickback saw chains"
which are available at your dealer. Saw chains Husqvarna H81 and H80 are both examples of listed "Low kickback
sawchains".
