Recommended original and replacement
bar and chain combinations
Following is a list of recommended cutting equipment for the
Jonsered chain saw model 2149. The combinations of powerhead,
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 maxi-
mum 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 of sprocket teeth may be conside-
red 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 B 175.1.
We recommend that you as replacement use the listed chains or
"Low kickback saw chains" which are available at your dealer.
