• Front Hand Guard, designed to reduce the
chance of your left hand contacting the chain
if your hand slips off the front haediebar,
• Position
of front and rear handlebars,
de-
signed with distance between
handles and
"in-line" with each other.
The spread and
"in-line" position
of the hands provided
by
this design work together to give balance
and resistance
in controlling
the pivot of
the saw back toward
the operator
if kick-
back occurs.

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 ofthe guide bar. This action may

push the guide bar rapidly back toward the op-
erator.
Either of these events may cause you
to Iose 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 deaIer, 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
will 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
listed is not recommended
and
may
not meet the CKA
requirements
per
standard.
