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 action may
push the guide bar rapidly back toward the op-
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 chain brake should be made by an autho-
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.
• Tip contact in some cases may cause a light-
ning fast reverse REACTION, kicking guide
bar up and back toward operator.
• Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
• Either of these reactions may cause you to
lose control of the saw which could result in
serious injury. Do not rely exclusively upon
devices built into your saw.
,,_ WARNING: Computed kickback
angle (CKA) listed on your saw and listed in the
CKA table below represents angle of kickback
your bar and chain combinations witl have
when tested in accordance with CSA (Cana-
dian Standards Association) and ANSI stan-
dards. When purchasing replacement bar and
chain, considerations should be given to the
lower CKA values. Lower CKA values repre-
sent safer angles to the user, higher values in-
dicate more angle and higher kick energies.
Computed angles represented indicate total
energy and angle associated without activation
of the chain brake during kickback. Activated
angle represents chain stopping time relative to
activation angle of chain break and resulting
kick angle of saw. In all cases lower CKA val-
ues represent a safer operating environment
for the user.
The following guide bar and chain combina-
tions meet kickback requirements of CSA
Standards Z62.1, Z62.3, & ANSI B175.1
when used on saws listed in this manual.
Use of bar and chain combinations other
than those tisted is not recommended and
may not meet the CKA requirements per
standard.
