To reduce the risk of injury, follow the specified
safety precautions.

0458-716-8221-D 5
English 5 IMPORTANT SAFETY INSTRUCTIONS
5.1 Intended Use
WARNING
￭ This chain saw is designed for cutting small diameter
trees, branches and limbs around the home. It is not
designed for felling large trees or cutting large diameter
logs. Use of the chain saw for operations different than
intended could result in serious injury or death.
– Cut wood only. For example, do not use chain saw
for cutting metal, plastic or masonry.
– Use this chain saw only for light-duty cutting tasks
around the home and garden.
– Do not use it for any other purposes.
￭ For cutting larger trees, logs or branches, a more
powerful, faster saw may be necessary to reduce the risk
of binding, stalling or other risks caused by a change in
conditions during longer cutting times. This battery-
operated chain saw is not suitable for cutting larger trees
and logs, and its use could lead to a loss of control of the
object being cut and serious personal injury or death.
– A battery-powered chain saw is of only limited
suitability for felling and limbing.
– Before starting any felling operation, fully charge
your STIHL AK battery.
￭ Before starting any bucking, limbing, pruning or felling
operation, ensure that all necessary cuts can be
completed using the charge remaining in the
STIHL AK series battery. If you are unsure:
– Have multiple charged batteries available for use;
– Select a more powerful chain saw;
Read and follow all safety precautions in the
instruction manual. Improper use can lead to
serious or fatal personal injury or property
damage.
To reduce the risk of eye and head injury, always
wear proper eye protection and an approved
protective helmet, @5.3.
Avoid contact of the bar tip with any object. This
can cause the bar to kick suddenly up and back,
which may result in serious or fatal injury. Always
use two hands to operate the saw, @6.
To reduce the risk of injury or property damage
from unintended activation, remove the battery
any time the saw is not in use, @5.5.
To reduce the risk of electric shock, do not
expose the chain saw to rain, water or excessive
moisture. Store it indoors. If it is exposed to rain
or very damp conditions, take it to your
authorized STIHL servicing dealer before further
operation, @5.4.
To reduce the risk of personal injury or property
damage from fire or electric shock, keep the
charger dry. Protect it from rain, water, liquids
and damp conditions. For indoor use only, @9.
To reduce the risk of personal injury or property
damage from fire, explosion or burns, including
chemical burns, do not disassemble, crush,
drop, damage or heat the battery above 212 °F
(100 °C). Never expose it to fire or incinerate,
@8.
To reduce the risk of personal injury or property
damage from a short circuit, fire or explosion,
keep the battery dry. Protect it from rain, water,
liquids and damp conditions. Never immerse the
battery in water or other liquids, @8.
To reduce the risk of personal injury or property
damage from fire, use and store the battery only
within an ambient temperature range of 14 °F to
122 °F (- 10 °C to 50 °C), @8.

INSTRUCTIONS

English 5 IMPORTANT SAFETY INSTRUCTIONS
– Select a more powerful battery; or
– Consult a reputable tree removal professional.
￭ Read and follow the operating and use instructions in this
manual for approved applications and recommended
working techniques.
￭ The saw chain has many sharp cutters. If they contact
your flesh, they will cut you even if the chain is not moving.
– Always wear heavy-duty work gloves when handling
the saw or its chain.
– Keep hands, feet and other parts of your body away
from the chain.
￭ Reactive forces, including kickback, can be dangerous.
– 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, battery and charger 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 modified or
altered from its original design.
￭ The STIHL AK series battery is designed for use only with
compatible STIHL power tools.
￭ The STIHL AL 101, AL 300 or AL 500 series charger is
designed for charging STIHL AK and AP series batteries
only.
5.2 Operator
WARNING
￭ Working with the chain saw can be strenuous. The
operator must be in good physical condition and mental
health. To reduce the risk of personal injury from fatigue
and loss of control:
– 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, alcohol 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.
– Bystanders, especially children, and animals 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 phenomenon) or carpal tunnel
syndrome. These conditions reduce the hand's ability to
feel and regulate temperature. They produce numbness
and burning sensations and may also cause nerve and
circulation damage as well as tissue necrosis.
￭ All factors which contribute to white finger disease 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
exposure 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.

0458-716-8221-D 7
English 5 IMPORTANT SAFETY INSTRUCTIONS
– Keep the saw chain sharp. A dull chain will increase
cutting time, and pressing a dull chain through wood
will increase the vibration transmitted to your hands.
– Maintain a firm grip at all times, but do not squeeze
the handles with constant, excessive 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 consult their
physician and device manufacturer 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.
￭ Loss of control and severe cut injuries may result if hair,
clothing or apparel make contact with the moving saw
chain or otherwise become entangled in the components
of the saw. To reduce the risk of severe personal injury:
– Wear a long-sleeve shirt or jacket.
– Avoid loose-fitting jackets, scarves, neckties, flared
or cuffed pants, jewelry and any other apparel that
could be caught on branches, brush or the moving
saw chain.
– Secure hair above shoulder level before starting
work.
￭ To reduce the risk of eye injury:
– To reduce the risk of injury to your face, STIHL
recommends that you also wear a face shield or face
screen over your goggles or protective glasses.
￭ To reduce the risk of head injury from falling branches or
other objects encountered during work:
– Wear an approved protective helmet.
￭ Chain saw noise may damage your hearing. Although this
battery-powered product is relatively quiet, to reduce the
risk of hearing damage:
– Wear sound barriers (ear plugs or ear muffs).
– Regular operators should have their hearing
checked periodically.
– Be particularly alert and cautious when using
hearing protection. Your ability to hear shouts,
alarms or other audible warnings is restricted.
￭ Good footing is very important. To help maintain a secure
footing and reduce the risk of injury while working:
￭ To improve your grip and help protect your hands:
– Wear sturdy and snug-fitting clothing that
also allows complete freedom of
movement.
– Wear the type of overalls, long pants or
chaps that contain pads of cut-retardant
material.
