Technical Data; Bar And Chain Combinations - Husqvarna 445 Operator's Manual

TECHNICAL DATA
Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvarna chain saw models 445, 445e, 450 and 450E.
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 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.
Recommended cutting equipment for Canada
The following is a list of recommended cutting equipment for chain saws 445, 445e, 450 and 450e. The combinations of
powerhead, bar and chain meet all requirements outlined in the CSA Z62.1-03 Chainsaws and Z62.3-04 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 "Type C Low-Kickback Saw Chains" which
are available at your dealer.
