Recommended bar and chain combinations

Following is a list of recommended cutting equipment for the Husqvarna Models 45 and 49. The combinations of powerhead, bar and chain have been investigated in accordance with the kickback requirements of ANSI B 175.1 – 1991. 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 protection.

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 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 is has 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 B 175.1. We recommend that you as replacement use the listed chains or "Low kickback saw chains" which are available at your dealer.
