TECHNICAL DATA
Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Jonsered chain saw model CS 2255. 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 hard nose.
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.
Bar and chain combinations
Note: For the saw chains above (if available) you are free to choose between 0,050" or 0,058" gauge drive links for the
corresponding bar, see the table below.
