exposure to vibration are mentioned as 
factors in the development of whitefinger 
disease. In order to reduce the risk of 
whitefinger 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.
– Wear gloves and 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 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 
interfere with some pacemakers. To 
reduce the risk of serious or fatal injury, 
persons with a pacemaker should 
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
Be particularly alert and cautious when 
wearing hearing protection because 
your ability to hear warnings (shouts, 
alarms, etc.) is restricted.
Avoid loose-fitting jackets, 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.
THE POWER TOOL
For illustrations and definitions of the 
power tool parts see the chapter on 
"Main Parts".
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 Z 87.1 (or your 
applicable national stand-
ard). 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 an approved safety 
hard hat to reduce the 
risk of injury to your head.
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.
Always wear heavy duty 
work gloves (e.g. made of 
leather or other wear 
resistant material) when 
handling the machine 
and the cutting tool. 
Heavy-duty, nonslip 
gloves improve your grip 
and help to protect your 
hands.
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. Do not wear 
shorts, sandals or go 
barefoot.
Good footing is very 
important. Wear sturdy 
boots with nonslip soles. 
Steel-toed safety boots 
with cut retardant inserts 
are recommended.
