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 model RedMax GZ500 meet 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

kickback requirements when equipped with the listed

We recommend only to use the listed guide bar and saw
chain combinations.
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.
