1.3 Engineering improvements
STIHL's philosophy is to continually improve all
of its products. For this reason we may modify
the design, engineering and appearance of our
products periodically.
Therefore, some changes, modifications and
improvements may not be covered in this man‐
ual.
2 Safety Precautions
This special chain saw shall be used
only by persons who are trained in
special cutting and working techni‐
ques.
Due to the special handle design
(closely spaced handles) there is an
increased risk of injury using this kind
of saw (cut injuries due to uncontrol‐
led reactive forces of the chain saw).
Special safety precautions must be
observed to reduce the risk of per‐
sonal injury when working with a
chainsaw because of the very high
chain speed and very sharp cutters.
It is important that you read the
instruction manual before first use
and keep it in a safe place for future
reference. Non-observance of the
instruction manual may result in seri‐
ous or even fatal injury.
2.1 General
Observe all applicable local safety regulations,
standards and ordinances.
The use of noise emitting power tools may be
restricted to certain times by national or local
regulations.
If you have not used this model before: Have
your dealer or other experienced user show you
how to operate your machine or attend a special
course in its operation.
Minors should never be allowed to use a chain‐
saw. Exceptions to this rule are young persons
0458-508-8321-B
older than 16 who have been trained in special
cutting techniques with the tree surgery saw.
Keep bystanders, especially children, and ani‐
mals away from the work area.
The user is responsible for avoiding injury to third
parties or damage to their property.
Do not lend or rent your chain saw without the
instruction manual. All users must be specially
trained in tree surgery work with a tree surgery
saw and be familiar with this model and its oper‐
ation.
To operate a chain saw you must be rested, in
good physical condition and mental health. If you
have any condition that might be aggravated by
strenuous work, check with your doctor before
operating a chainsaw.
Do not operate the chain saw if you are under
the influence of any substance (drugs, alcohol)
which might impair vision, dexterity or judgment.
To reduce the risk of accidents or injury, put off
the work in poor weather conditions (rain, snow,
ice, wind).
Persons with pacemakers only: The ignition sys‐
tem of your chainsaw produces an electromag‐
netic field of a very low intensity. This field may
interfere with some pacemakers. To reduce
health risks, STIHL recommends that persons
with pacemakers consult their physician and the
pacemaker manufacturer before operating this
power tool.
2.2 Intended Use
Tree surgery chainsaws are special-purpose
saws equipped with a top handle. They are
designed specifically for tree surgery and mainte‐
nance in the crown of the standing tree.
Chainsaw operators must be properly secured
while working in a tree (e.g. lift bucket, personal
safety equipment, safety harness).
The chainsaw may be used for cutting wood and
wooden objects only.
It must not be used for any other purpose
because of the increased risk of accidents.
They must not be used for felling trees or cutting
firewood. Normal chainsaws with wider spaced
handles are recommended for such operations.
Never attempt to modify your saw in any way
since this may increase the risk of personal
injury. STIHL excludes all liability for personal
