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.

SAFE-T-TIP

Fig. 4

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
