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 serious or fatal injury. The terminology utilized in this manual when referring to the power tool reflects the fact that different types of cutting attachments may be mounted on it. The term “trimmer ” is used to designate an FS unit that is equipped with a nylon line head or a head with flexible plastic blades (i.e., the PolyCut head). A “brushcutter ” designates a unit equipped with a rigid metal blade. Many FS models may be used as either a trimmer or a brushcutter – therefore, the power tool is referred in this manual as a “trimmer/brushcutter. ” Some smaller and/or lightweight FS models may only be used as a trimmer, i.e., they may not be used with metal blades. !Warning As more fully explained later in these Safety Precautions, 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 on your FS model.
