are included on your saw to help reduce the
hazard of kickback; however, such features
will not  totally eliminate this danger.   As  a

vices.
You must  follow all  safety precau-
tions, instructions, and maintenance in this
manual  to help  avoid kickback  and  other
forces which can result in serious injury.
S  Reduced--Kickback Guide Bar, designed
with a small radius tip which reduces the
size of the kickback  danger zone on the
bar tip.  A Reduced--Kickback Guide Bar
has been demonstrated to significantly re-
duce the number and seriousness of kick-
backs  when  tested in  accordance  with
safety requirements for gasoline powered
chain saws as set by ANSI B175.1.
BACK.
Kickback  is a  lightning  fast  action
which throws the bar and rotating chain back
and up toward the operator. Kickback can be
caused by allowing contact of the bar tip in the
danger zone with any hard object.   Kickback
can also be caused by pinching the saw chain
along the top of the guide bar. This actionmay
push the guide bar rapidly back toward theop-
erator.  Either of these events may cause you
to lose control of the saw which could result in
serious injury or even death. DO  NOT RELY
UPON ANY OF THE DEVICES BUILT INTO
YOUR SAW. YOU SHOULD USE THE SAW
PROPERLY AND  CAREFULLY  TO AVOID

KICKBACK.
Reduced--kickback guide  bars
and  low--kickback  saw  chains  reduce  the
chance and  magnitude of kickback  and are
recommended.  Your saw has a low kickback
chain and bar as original equipment. Repairs
on a chainbrake shouldbe madeby anautho-
rized servicing dealer.   Take your unit  to the
place of purchase if purchased from a servic-
ing dealer, or to the nearest authorized master
service dealer.
