• 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
handtes 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.
Kickback
is a lightning fast ac-
tion 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

action may push the guide bar rapidly back
toward the operator.
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
AN D
CAREFULLY
TO AVOID
KICKBACK.
Re-
duced-kickback
guide bars
and low-kick-

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.
_L, 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 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.

in all cases
lower CKA values
represent
a

for the user.
