LOW KICKBACK SAW CHAIN
The ramp-shaped depth gauges 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 a replacement chain that is equivalent to the original
chain or has been certified as a low kickback chain per ANSI B175.1. A low
kickback tooth saw chain is a chain that has met the kickback performance
requirements of ANSI B175.1 (American National Standard for Power Tools-
Gasoline-Powered Chainsaws-Safety Requirements) when tested on the
representative sample of chainsaws below 3.8 c.i.d. specified in ANSI B175.1.
The bumper drive link (Fig. 2) also helps deliver low-kickback performance.

CAUTION: As saw chains are sharpened during their useful life, they lose some
of the low kickback qualities and extra caution should be used.
GUIDE BAR
This saw comes equipped with a guide bar that has a small radius nose. Small
radius noses generally have less potential for kickback. When replacing the guide
bar, be sure to order the bar listed in this manual.
ADDITIONAL WARNINGS
With a basic understanding of kickback (Fig. 3-5), you can reduce or eliminate
the element of surprise. Sudden surprise contributes to accidents.
