must be observed to reduce the risk of 
personal injury.
It is important that you 
read, fully understand and 
observe the following 
safety precautions and 
warnings. Read the 
instruction manual and 
the safety precautions periodically. 
Careless or improper use may cause

!Warning!
To reduce the risk of injury to bystanders 
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 
unauthorized persons do not use it.
Most of these safety precautions and 
warnings apply to the use of all STIHL 
trimmer/brushcutters. Different models 
may have different parts and controls. 
See the appropriate section of your 
instruction manual for a...

Keep the AV system well maintained. A 
power tool with loose components or 
with damaged or worn AV buffers will 
tend to have higher vibration levels.
Maintain a firm grip at all times, but do 
not squeeze the handles with constant, 
excessive pressure. Wear gloves and 
keep your hands warm. Take frequent 
breaks. 
All the above-mentioned precautions do 
not guarantee that you will not sustain 
whitefinger disease or carpal tunnel 
syndrome. Therefore,...
