chain brake should be made by an autho-
rized servicing dealer . Take your unit to the
place of purchase if purchased from a
Husqvarna servicing dealer , or to the near-
est authorized Husqvarna service dealer.
S Tip contact in some cases may cause a
lightning fast reverse REACTION, kicking
the guide bar upand back towardtheoper-
ator.
S Pinching the saw chain along the top ofthe
guide bar may push the guide bar rapidly
back toward the operator.
S Either of these reactions may cause youto
lose control of the saw which could result
in serious injury . Do not rely exclusively
uponthesafety devices built into your saw.
W ARNING:
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 (CanadianStandards Association) and
ANSI standards. When purchasing replace-
ment 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 rep-
resented in the non-activated column indi-
cate total energy and angle associated with-
out 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 values 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.

SAFETY NOTICE:
Exposure to
vibrations throughprolongeduse of gasoline
powered hand tools could cause blood
vessel or nerve damage in the fingers,
hands, and joints of people prone to
circulation disorders or abnormal swellings.
Prolonged use in cold weather has been
linked to blood vessel damage in otherwise
healthy people. If symptoms occur such as
numbness, pain, loss of strength, change in
skin color or texture, or loss of feeling in the
fingers, hands, or joints, discontinue the use
of this tool and seek medical attention. An
anti-vibrationsystem doesnot guaranteethe
avoidance of these problems. Users who
operate power tools on a continual and
regular basis must monitor closely their
physical condition and the condition of this
tool.
SPECIALNOTICE:
Yoursaw is equipped
with a temperaturelimiting muffler and spark
arresting screen which meets the
requirements of California Codes 4442 and
4443. All U.S. forest land and the states of
California, Idaho, Maine, Minnesota, New
Jersey, Oregon, and Washington require
many internal combustion engines to be
equipped with a spark arrestor screen by
law. If you operate a chain saw in a state or
locale where such regulations exist, you are
legally responsible for maintaining the
operatingcondition of these parts. Failureto
do so is a violation of the law. Refer to the
SERVICEAND ADJUSTMENTS section for
maintenance of the Spark Arresting Screen.
Failure to follow all Safety Rules and
Precautions can result in serious injury. If
situations occur which are not coveredin this
manual, use care andgoodjudgement. Ifyou
need assistance, contact your authorized
service dealer.
