chain brake

The chainsaw comes equipped with
a chain brake, which stops both the
motor and the motion of the chain
when kickback occurs (Fig. 2). The chain
brake can be activated by the forward
motion of the hand guard as the saw
rotates backward during kickback; it can
also be activated by the inertial forces
generated during rapid pushback.
Fig. 2
danger: never modify or
attempt to disable the
chain brake.
chain
This saw comes equipped with a saw
chain that met the reduced kickback
requirements of ANSI B175.1 when
tested on a representative sample of
chainsaws . For replacement chain, see
"specifications and components" in this
manual .
bar
This saw comes equipped with a
guide bar that has a small radius nose .
Small radius noses generally have less
potential for kickback.
when replacing the bar, be sure to order
the bar listed in this manual .

battery safety

danger: failure to folloW
these safety rules can
cause the battery pack to
leak hazardous chemicals,
overheat, emit smoke, burst,
flare, explode, and/or ignite.
• Do not disassemble or modify the
battery pack. The battery pack is
equipped with built-in safety and
protection features which may be
inadvertently disabled.
• Do not connect the positive (+) and
negative (-) terminals with metal
objects. Do not transport or store
the battery pack together with metal
objects such as coins or screws. Short-
circuiting may occur or the metal object
in contact with the battery pack can
generate heat .
• Do not discard the battery pack into
fire or otherwise expose to excessive
heat . such conditions can cause the
insulation to melt or safety features to
be damaged .
• Do not use, charge, or store the battery
pack near a heat source as fire or a
heater that generate temperatures
above 80°c (176°F) . overheating and/or
internal short circuiting may occur.
• Do not immerse the battery pack in
water or expose it to extremely wet
conditions . moisture can cause the
protective features to be damaged,
resulting in charging with extremely
high current and voltage, which may
lead to abnormal chemical reactions .
• To recharge the battery pack, use the
battery charger specifically designed
for the battery pack and observe the
specified charger safety precautions
detailed in this manual . Failure to
do so may result in extremely high
current and voltage, which may lead to
abnormal chemical reactions .
