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.
