Safety Precautions and Working Techniques Because a trimmer is a high-speed, fast-cutting power tool, special safety precautions 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 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).

A description of a step or procedure that refers directly to an illustration may contain item numbers that appear in the illustration. Example: N N Loosen the screw (1) Lever (2).
