Recommended cutting equipment for Canada
Following is a list of recommended cutting equipment for the Husqvarna chainsaw model s 445 II, 445e II, 450 II and
450e II. The listed combination(s) of powerhead, bar and saw chain meet all requirements outlined in Canadian
Standards Assosiation Z62.1-15 (Chain Saws) and Z62.3-11 (R2016) (Chain Saw Kickback).
Furthermore the saw chain Husqvarna H30 is evaluated and listed as a Type C Low Kickback Saw Chain according to
the provisions in Z62.3-11 (R2016).
Kickback information
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.
