S
Low--Kickback Chain, designed with a
contoured depth gauge and guard link
which deflect kickback force and allow
wood to gradually ride into the cutter. Low--
Kickback Chain has met kickback per-
formance requirements when tested on a
representative sample of chain saws be-
low 3.8 cubic inch displacement specified
in ANSI B175.1.

S
Front Hand Guard, designed to reduce the
chance of your left hand contacting the
chain if your hand slips off the front handle-
bar.
S
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 AND CKA ANGLE
S
Chain Brake, designed to stop the chain in
the event of kickback.
WARNING:
WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS-
SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OF A
KICKBACK. Kickback is a lightning fast ac-
tion which throws the bar and rotating c hain
back and up toward the operator. Kickback
can be caused byallowing contact of the bar
tip in the danger zone with any hard object.
Kickback can also becaused by pinching the
sawchain along the topof 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 o f the saw
which could result in serious injury or even
death. DO NOT RELY UPON ANY OFTHE
DEVICES BUILT INTO YOUR SAW. YOU
SHOULD USE THE SAWPROPERLYAND
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 hasa low kickback chain
and bar as original equipment. Repairs on a
chain brake should be made by an autho-
rized servicing dealer. Tak e your unit to the
place of purchase if purchased from a ser-
vicing dealer, or to the nearest authorized
master s ervice dealer.

Either of these reactions may cause you to

devices built into your saw.
WARNING:
Computed kickback
angle (C KA) listedon yoursaw andlisted in the
CKA table below r epr esents angle of kickback
your bar and chain combinations will have
when tested i n accordance with CSA (Cana-
dian Standards Association) and ANSI stan-
dards. W hen 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 ener gies.
Computed angles r epr esented indicate total
energy andangle associated withoutactivation
of the chain b r ake during kickback. A ctivated
angle representschain stopping timerelativeto
activation angle of chain break and r esulting
kick angle of saw. In all cases low er C KA v al-
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.
