factors in the development of white
finger disease. In order to reduce the
risk of white finger disease and carpal
tunnel syndrome, please note the
following:
Most STIHL power tools are
–
available with an anti-vibration
("AV") system designed to reduce
the transmission of vibrations
created by the machine to the
operator's hands. An AV system is
recommended for those persons
using power tools on a regular or
sustained basis.
Keep your hands warm.
–
Keep the AV system well
–
maintained. A power tool with loose
components or with damaged or
worn AV elements will tend to have
higher vibration levels.
Maintain a firm grip at all times, but
–
do not squeeze the handle with
constant, excessive pressure. Take
frequent breaks.
All the above-mentioned precautions do
not guarantee that you will not sustain
white finger disease or carpal tunnel
syndrome. Therefore, continual and
regular users should closely monitor the
condition of their hands and fingers. If
any of the above symptoms appear,
seek medical advice immediately.
WARNING
The ignition system of the STIHL unit
produces an electromagnetic field of a
very low intensity. This field may
interfere with some pacemakers. To
reduce the risk of serious or fatal injury,
persons with a pacemaker should
4
consult their physician and the
pacemaker manufacturer before
operating this tool.
Proper Clothing
WARNING
To reduce the risk of injury, the operator
should wear proper protective apparel.
WARNING
To reduce the risk of
injury to your eyes never
operate your power tool
unless wearing goggles
or properly fitted protec-
tive glasses with
adequate top and side
protection complying with
ANSI Z87 "+" (or your
applicable national
standard).
Power tool noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
protect your hearing.
Continual and regular
users should have their
hearing checked
regularly.
Be particularly alert and cautious when
wearing hearing protection because
your ability to hear warnings (shouts,
alarms, etc.) is restricted.
Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement.
Avoid loose-fitting jack-
ets, scarfs, neckties,
jewelry, flared or cuffed
pants, unconfined long
hair or anything that
could become drawn into
the air intake. Secure hair
so it is above shoulder
level.
Good footing is very
important. Wear sturdy
boots with nonslip soles.
Steel-toed safety boots
are recommended.
WARNING
To reduce the risk of injury when the
inhalation of dust cannot be
substantially controlled use an
appropriate respirator for the material
being blown. For more information see
the "Working conditions" section of
these Safety Precautions.
THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
"Main Parts."
WARNING
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may,
in fact, be extremely dangerous.
