Approved bar and chain combinations
"Low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B 175.1-1991
(American National Standard for Power Tools-Gasoline-Powered Chain Saws-Safety Requirements) when tested on the
representative sample of chain saws below 3.8 c.i.d. specifed in ANSI B 175.1-1991". The approved bar and chain
combinations are low kickback chains according to ANSI B 175.1-1991 and also meet the kickback requirements of
CSA Z62.3-96 for chains saws below 80 cm
3
.
WARNING
Do not use other replacement bars and chains unless they have been designated as meeting the ANSI B 175.1-1991
(for USA) and CSA Z62.3-96 (for Canada) kickback performance requirements on that specific powerhead, or has
been designated as "low kickback" saw chain in accordance with the ANSI B 175.1-1991 (for USA) and CSA
Z62.3-96 (for Canada) standard.
