GENERAL SAFETY RULES
UNDERSTANDING YOUR CHAIN SAW SAFETY
DEVICES
See Figure 4.
SAFE-T-TIP
®
ANTI-KICKBACK NOSE GUARD
The SAFE-T-TIP
®
prevents rotational kickback from hap-
pening, because it covers the tip of the bar where kickback
is generated. Never attempt any kind of cutting where the
SAFE-T-TIP
®
would have to be removed from the bar tip.
LOW KICKBACK SAW CHAIN
The rakers (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
replacement chain that is equivalent to original chain or has
been certified 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 - Gas-
oline-Powered Chain Saws-Safety Requirements) when
tested on the representative sample of chain saws below
3.8 c.i.d. specified 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.
GUIDE BARS
Generally, guide bars with small radius tips have somewhat
lower kickback potentials.
When making a replacement, be sure to order one of the
Ryobi bars listed for the saw in this operator's manual. The
proper size SAFE-T-TIP
®
nose guard comes installed on the
bar. Use only guide bars that have a provision for mounting
the SAFE-T-TIP
