Recommended original and replacement bar and chain combinations for USA
Following is a list of recommended cutting equipment for the Husqvarna chain saw models 235 and 240. 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 B 175.1–2000.
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 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.
Chain saw models Husqvarna 235 and 240 met the kickback performance requirements of ANSI B 175.1-2000 when tested
with the combinations of bars and saw chains listed below. The saw chains Oregon 91VG and 90SG are also classified as
a low kickback saw chain since it met the requirements for low kickback saw chain outlined in ANSI B 175.1-2000. We
recommend to use only the listed combinations of bars and chains for chain saw models Husqvarna 235 and 240. Other
chain saw models may not meet the kickback requirements when equipped with the listed bar and chain combinations.
Recommended cutting equipment for Canada
The following is a list of recommended cutting equipment for Class 1A and 1B Chainsaws. The combinations of powerhead,
bar and chain meet all requirements outlined in the CSA Z62.1-95 Chainsaws and Z62.3-96 Chainsaw Kickback standards.
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.
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.
We recommend that you as replacement use the listed bars and chains or ÅhType C Low-Kickback Saw ChainsÅh which
are available at your dealer.
