• Push and Pull - This reaction force is always
opposite to the direction the chain is moving
where wood contact is made. Thus, the oper-
ator must be ready to control the PULL when
cutting on the bottom edge of the bar, and
PUSH when cutting along the top edge.
Understanding your chain saw safety devices
Low kickback saw chain
Low kickback saw chain The rakers (depth gaug-
es) ahead of each cutter can minimize the force
of a kickback reaction by preventing the cutters
from digging in too deeply at the kickback zone.
Only use replacement chain that is equivalent to
original chain or has been certied as low kickback
chain per ANSI B175.1. Low kickback/skip tooth
saw chain is a chain that has met the kickback
performance requirements of ANSI B175.1 - 1991.
(American National Standard for Power Tools -
Gasoline-Powered Chain Saws-Safety Require-
ments) when tested on the representative sample
of chain saws below 3.8 c.i.d. specied in ANSI
B175.1-1991. As saw chains are sharpened during
their useful life, they lose some of the low kickback
qualities and extra caution should be used.
