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 type of cutting attachments that 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). FS models with an “R ” on the nameplate were originally configured (at the time of distribution) as a trimmer with a loop handle. !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. To reduce the risk of severe or fatal injury from blade contact and/or loss of control, never attempt to use a metal blade on this trimmer. Have your STIHL dealer show you how to operate your power tool. Observe all applicable local safety regulations, standards and ordinances. !Warning! The 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 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.
