WARNING
As more fully explained later in this manual, to reduce the 
risk of personal injury, make sure your unit is equipped with 
the proper handle, harness and deflector for the type of 
cutting attachment you are using. Use only cutting 
attachments that are specifically authorized by STIHL for 
use with this power tool. Always wear proper protective 
apparel and eye protection. Bystanders, especially children, 
and animals should not be allowed in the work area where 
the trimmer is in use.
WARNING
Use of this machine may be hazardous. If the rotating line or 
blade comes in contact with your body, it will cut you. When 
it comes in contact with solid foreign objects such as rocks, 
glass or bits of metal, it may fling them directly or by ricochet 
in the direction of bystanders or the operator. Striking such 
objects could damage the cutting attachment and may 
cause blades to crack, chip or break. Thrown objects, 
including broken heads or blades, may result in serious or 
fatal injury to the operator or bystanders. Follow the safety 
precautions in this manual to reduce the risk of personal 
injury.
