• Front Hand Guard, designed
to reduce the
chance of your left hand contacting the chain
if your hand slips off the front handlebar.
• 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.

• Chain Brake, designed
to stop the chain in

_I_WARNING:
WE DO NOT REP-

YOU
SHOULD
NOT
AS-
SUME
THAT
THE

BRAKE
WILL
PROTECT
YOU
IN THE
EVENT
OF
A
KICKBACK.
Kickback
is a lightning
fast ac-
tion which throws the bar and rotating chain
back and up toward the operatoE
Kickback
can be ca used 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 operator.
Either of these events
may cause you to lose controt
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.
Re-
duced-kickback
guide
bars
and low-kick-
back
saw
chains
reduce
the chance
and
magnitude
of kickback
and
are
recom-
mended.
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 ser-
vicing
dealer,
or to the nearest
authorized
master
service dealer.
• Tip contact in some cases may cause a light-
ning fast reverse REACTION,
kicking the
guide bar up and back toward the 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 controt of the saw which
could result
in serious
injury.Do
not rely exclusively
upon the safety devices built into your saw.
,1_ WARNING:
Computed
kickback
angle (CKA) listed on your saw and listed in
the
CKA table below
represents
angie
of
kickback
your
bar and chain combinations
will have when
tested
in accordance
with
CSA and ANSI standards.
When purchasing
replacement
bar and chain, considerations
should
be given to the lower
CKA values.
Lower CKA values represent
safer angles to
the user, higher values
indicate
more angle
and higher
kick energies.
Computed
angles
represented
in the non-activated
cotumn in-
dicate
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 brake and resulting
kick angle of saw.
In all cases
lower
CKA values
represent
a
safer operating
environment
for the user.
The following
guide bar and chain combina-
tions
meet
kickback
requirements
of CSA
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.
