do not squeeze the handles with
constant, excessive pressure. Take
frequent breaks.
All the above-mentioned precautions do
not guarantee that you will not sustain
whitefinger 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 inter-
fere with some pacemakers. To reduce
the risk of serious or fatal injury, persons
with a pacemaker should consult their
physician and the pacemaker manufac-
turer before operating this tool.

Clothing must be sturdy
and snug-fitting, but allow
complete freedom of
movement. Wear long
pants made of heavy
material to help protect
your legs from contact
with branches or brush.
To reduce the risk of cut
injuries, wear pants or
chaps that contain pads
of cut retardant material.
Avoid loose-fitting jack-
ets, scarfs, neckties,
jewelry, flared or cuffed
pants, unconfined long
hair or anything that
could become caught on
branches, brush or the
moving parts of the unit.
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.
Wear an approved safety
hard hat to reduce the
risk of injury to your head.
Chain saw noise may
damage your hearing.
Wear sound barriers (ear
plugs or ear mufflers) to
help 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.
Never operate your power tool unless
wearing goggles or properly fitted
protective glasses with adequate top
and side protection complying with ANSI
Z 87.1 (or your applicable national
standard). 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.
Always wear gloves
when handling the
machine and the cutting
tool. Heavy-duty, nonslip
gloves improve your grip
and help to protect your
hands.
