Recommended original and replacement bar
and chain combinations
Following is a list of recommended cutting equipment for
the Jonsered chain saw models 2045 and 2050. The
combinations of power head, bar and chain have been
investigated in accordance with the kickback and vibration
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 sprocket teeth may be considered to have equivalent
kickback energy. A hard nose bar having the same length
and nose radius as a sprocket-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.
