TECHNICAL DATA
Recommended cutting equipment for Canada
The following is a list of recommended cutting equipment for Chainsaws Husqvarna 545, 545 TrioBrake, 550XP, 550XP
TrioBrake, 550XPG and 550XPG TrioBrake. The combinations of powerhead, guide bar and saw 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.
The following cutting attachments are approved for the models Husqvarna 545, 545 TrioBrake, 550XP, 550XP TrioBrake,
550XPG and 550XPG TrioBrake.
Note: For guide bars with nominal length 20”, two different drive link counts exist. Always check information on the guide
bar to get the correct drive link count for a spare saw chain.
