Recommended cutting equipment
A specific chainsaw model has to be evaluated with
the cutting equipment to be recommended and fulfill the
requirements in ANSI B175.1-2012 (Internal Combustion
Engine-Powered Hand-Held Chainsaws - Safety and
Environmental Requirements) and Canadian Standards
CSA Z62.1-15 (Chainsaws) and CSA Z62.3-11 (R2016)
(Chainsaw kickback).
Chainsaw models Husqvarna 545 Mark II, 545G Mark
II, 550XP Mark II, 550XPG Mark II met the safety
requirements in ANSI B175.1-2012 and Canadian
Standards Association CSA Z62.1-15 (Chainsaws) and
CSA Z62.3-11 (R2016) (Chainsaw kickback), when
equipped with the below listed saw chain and guide bar
combination(s).
Note:
Other chainsaw models may not meet the
kickback requirements when equipped with the listed
guide bar and saw chain combinations.
We recommend only to use the listed guide bar and saw
chain combinations.
Low kickback saw chain
A saw chain that is designated as Low kickback saw
chain, meets the low kickback requirement specified in
ANSI B175.1-2012.
Kickback and guide bar nose radius
For sprocket nose bars the nose radius is specified by
the number of teeth, such as 10T. For solid guide bars
the nose radius is specified by the dimension of the
nose radius. For a given guide bar length, you can use a
guide bar with smaller nose radius than given.
Note:
The usable cutting length is usually 1 in less
than the nominal guide bar length.

Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder.
