Recommended original and replacement bar and chain combinations
The following is a list of recommended cutting equipment for chain saws 346XP, 346XPG, 346XP E-tech, 346XPG E-
tech TrioBrake et 353, 353G, 353 E-tech, 353G E-tech, TrioBrake. The combinations of power head, bar and chain have
been investigated 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 maxim
um 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
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.
