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.
