6 IMPORTANT SAFETY INSTRUCTIONS
– 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 battery.
– Read and follow the operating and use instructions
in this manual for approved applications and
recommended working techniques.
￭ The STIHL AK series battery is designed for use only with
compatible STIHL power tools.
￭ The STIHL AL series charger is designed for charging
STIHL AK and AP series batteries only.
￭ Improper use could result in personal injury or property
damage.
– Use the chain saw, battery and charger only as
described in this manual.
6.2 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.
￭ Prolonged use of a chain saw (or other power tools)
exposing the operator to vibrations 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 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 saw chain will
increase cutting time, and pressing a dull saw chain
through wood will increase the vibrations 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 user.
– 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 should consult
their physician and pacemaker manufacturer before
operating this chain saw.
