Chain Brake - Partner 422 Instruction Manual

S Tip contact in some cases may cause a light-
ning fast reverse REACTION, kicking the
guide bar up and back toward the operator.
S Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back toward the operator.
S Either of these reactions may cause you to
lose control of the saw which could result
in serious injury. Do not rely exclusively
upon the safety devices built into your saw.

CHAIN BRAKE

S Chain brake, designed to stop the chain in
the event of kickback.
WARNING
: Your chain saw is
equipped with a chain brake that is designed
to stop the chain immediately if you get a
kickback. The chain brake reduces the risk
of accidents, but only you can prevent them.
DO NOT ASSUME THAT THE CHAIN
BRAKE WILL PROTECT YOU IN THE
EVENT OF A KICKBACK.
WARNING
: Recheck each assem-
bly step if the saw is received assembled.
Protective gloves (not provided) should be
worn during assembly. Always wear gloves
when handling the chain. The chain is sharp
and can cut you even when it is not moving!

SAFETY NOTICE:
vibrations through prolonged use 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-vibration system does not guarantee the
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.
