• Front Handguard, 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 re-
sistance in contrelliog the pivot of the saw
back toward the operator if kickback occurs.
CHAIN
BRAKE
• Chain Brake, designed to stop the chain in
the event of kickback.

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 of the guide bar. This action may
push the guide bar rapidly back toward the op-
erator. Either of these events may caose you
to lose control of the saw which could result in
sedous 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 aL_ho-
nzed servicing dealer.
Take your unit to the
place of purchase if purchased from a servic-
ing dealer, or to the nearest authodzed master
service dealer.
• Tip contact
in some cases may cause a
lightning 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 ofthese
reactions maycauseyouto
lose control of the saw which could result
in serious
injury. Do not rely exclusively
upon safety 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 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
column in-
dicate total
energy
and angle associated
without activation
of the chain brake dudng
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.f 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.
