Most of these safety precautions and 
warnings apply to the use of all STIHL 
trimmers / brushcutters. Different 
models may have different parts and 
controls. See the appropriate section of 
your instruction manual for a description 
of the controls and the function of the 
parts of your model.
Safe use of a trimmer / brushcutter 
involves
1. the operator
2. the power tool
3. the use of the power tool.
THE OPERATOR
Physical Condition
You must be in good physical condition 
and mental health and not under the 
influence of any substance (drugs, 
alcohol, etc.) which might impair vision, 
dexterity or judgment. Do not operate 
this machine when you are fatigued.
These conditions reduce the hand's 
ability to feel and regulate temperature, 
produce numbness and burning 
sensations and may cause nerve and 
circulation damage and tissue necrosis.
All factors which contribute to 
whitefinger disease are not known, but 
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 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!
To reduce the risk of injury to bystand-
ers and damage to property, never let 
your power tool run unattended. When it 
is not in use (e.g. during a work break), 
shut it off and make sure that unauthor-
ized persons do not use it.
Warning!
Be alert – if you get tired, take a break. 
Tiredness may result in loss of control. 
Working with any power tool can be 
strenuous. If you have any condition 
that might be aggravated by strenuous 
work, check with your doctor before 
operating this machine.
Warning!
Prolonged use of a power tool (or other 
machines) exposing the operator to 
vibrations may produce whitefinger dis-
ease (Raynaud's phenomenon) or 
carpal tunnel syndrome.
