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.
