GUIDE BAR
(Low-kickback) Replacement guide bars.
The following guide bars may be considered to have equivalent kickback energy.
• Sprocket nose guide bars of the same length and nose radius, same pitch and having the same number of teeth.
• Hard nose guide bars of the same length and nose radius as a sprocket nose bar.
SAW CHAIN
CAUTION
Do not use replacement saw chain unless it has been designated as meeting the ANSI B175.1 - 2000 kickback performance requirements, when tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI B175.1 - 2000.
NOTE
LOW KICKBACK SAW CHAIN meets the kickback performance requirements of ANSI B175.1 - 2000 (safety requirements for gasoline- powered chain saws).
