5 IMPORTANT SAFETY INSTRUCTIONS
► Pay special attention to the sections of this
instruction manual dealing with reactive
forces.
■ Observe all applicable federal, state and local
safety regulations, standards and ordinances.
■ Improper use could result in personal injury or
property damage, including damage to the
chain saw.
► Use the chain saw and battery only as
described in this manual.
► Never attempt to modify or override the
chain saw's controls or safety devices in
any way.
► Never use a chain saw that has been modi‐
fied or altered from its original design.
► Be sure to read and follow the warnings
and instructions for your battery and
charger before charging or starting work.
■ This power tool may be powered by a
STIHL AP series battery. Alternatively, it may
be powered by a STIHL AR series backpack
battery in combination with an AP Adapter.
■ Using an AR series battery or AP battery bag
with connecting cord while climbing in a tree is
not authorized because it could lead to entan‐
glement of the connecting cord or otherwise
increase the risk of injury from loss of control
or loss of balance.
► Use an AR series battery or AP battery bag
with connecting cord only when working
from a lift bucket. Never use while climbing
in a tree.
Batteries, chargers and other accessories are
sold separately.
5.2 Operator
WARNING
■ Working with the chain saw can be strenuous.
The operator must be in good physical condi‐
tion and mental health. To reduce the risk of
personal injury:
► Check with your doctor before using the
chain saw if you have any health condition
that may be aggravated by strenuous work.
► Do not operate the chain saw while under
the influence of any substance (drug, alco‐
hol or medication, etc.) that might impair
vision, balance, dexterity or judgment.
► Be alert. Do not operate the chain saw
when you are tired. Take a break if you
become tired.
► Do not permit minors to use the chain saw.
0458-791-8221-D
► Bystanders, especially children, and ani‐
mals should not be allowed in the area
where the chain saw is in use.
■ Prolonged use of a chain saw (or other power
tools) exposing the operator to vibration may
produce white finger disease (Raynaud's phe‐
nomenon) or carpal tunnel syndrome. These
conditions reduce the hand's ability to feel and
regulate temperature. They produce numb‐
ness and burning sensations and may also
cause nerve and circulation damage as well
as tissue necrosis.
■ All factors which contribute to white finger dis‐
ease are not known. Cold weather, smoking
and diseases or physical conditions that affect
blood vessels and blood transport, as well as
high vibration levels and long periods of expo‐
sure to vibration, are mentioned as factors in
the development of white finger disease.
■ To reduce the risk of white finger disease and
carpal tunnel syndrome:
► Wear gloves while working and keep your
hands warm.
► Keep the chain saw well maintained. An
improperly maintained chain saw or one
with loose components will tend to have
higher vibration levels.
► Keep the saw chain sharp. A dull chain will
increase cutting time, and pressing a dull
chain through wood will increase the vibra‐
tion transmitted to your hands.
► Maintain a firm grip at all times, but do not
squeeze the handles with constant, exces‐
sive pressure. Take frequent breaks.
■ These precautions do not guarantee that you
will not sustain white finger disease or carpal
tunnel syndrome.
► Closely monitor the condition of your hands
and fingers if you are a regular operator.
► Seek medical advice immediately if any of
the above symptoms appear.
■ According to STIHL's current knowledge, the
electric motor of this chain saw should not
interfere with a pacemaker.
► However, persons with a pacemaker or
other implanted medical device should con‐
sult their physician and device manufac‐
turer before operating this chain saw.
5.3 Personal Protective Equipment
WARNING
■ To reduce the risk of personal injury:
► Always wear proper clothing and protective
apparel, including proper eye protection.
