English 1 Introduction
Thank you for your purchase. The information contained in
this manual will help you receive maximum performance and
satisfaction from your STIHL chain saw and, if followed,
reduce the risk of injury from its use.
This lightweight, top-handle chain saw is designed
specifically for in-tree operation by arborists and other tree
care professionals. Its compact design makes it particularly
useful for in-tree maintenance, tree surgery and other
cutting work in confined spaces where greater
maneuverability is required. For cutting work at ground level,
use a traditional rear-handle chain saw with a wider handle
configuration for greater control.
SAVE THIS MANUAL!
WARNING
Operating this chain saw in a tree requires special working
techniques, which must be observed to reduce the risk of
personal injury. Never work in a tree unless you have
received specific, professional training for such work,

English 5 IMPORTANT SAFETY INSTRUCTIONS
￭ This chain saw should be used only for work in a tree by
persons trained in special cutting and working techniques.
Because this saw is not intended for use on the ground,
this manual does not contain instructions for felling or for
limbing or bucking felled trees.
– Cut wood only. For example, do not use chain saw
for cutting metal, plastic or masonry.
– 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 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 modified 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.
￭ Do not use STIHL AR batteries or AP series batteries in a
battery bag with connecting cord with STIHL MSA
top-handle chain saws while climbing in a tree for in-tree
surgery and maintenance. Use could lead to severe
personal injury and property damage from entanglement
of the connecting cord, loss of control, or loss of balance.
– If using an AR series battery or AP series battery in
a battery bag with connecting cord always use a lift
bucket for in-tree surgery and maintenance. Do not
climb in the 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 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.

0458-791-8221-C 7
English 5 IMPORTANT SAFETY INSTRUCTIONS
￭ 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
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.
– Any crew member in the cutting area should also
proper protective equipment, including an approved
helmet.
– 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 top and
side protection that are impact-rated and
marked as complying with CSA Z94.
