– 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.
– 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.

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.
To reduce the risk of injury or property damage,
immediately disconnect the chain saw from the
power supply if the power supply cord or the
extension cord is damaged, @5.6.
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.

5 IMPORTANT SAFETY
INSTRUCTIONS

0458-729-8221-A

English 5 IMPORTANT SAFETY INSTRUCTIONS
– 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.
– 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.
– 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.
– Always wear goggles or close-fitting
protective glasses with adequate side
protection that are impact-rated and
marked as complying with CSAZ94.
