Stihl FS 46 Product Instruction Manual - Page 14

English Warning! 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. Using the Mowing Heads Do not use with mowing line longer than the intended length. With a properly mounted deflector, the built-in linelimiting blade will automatically adjust the line to its proper length. Using the unit with an overly long nylon cutting line increases the load on the engine and reduces its operating speed. This causes the clutch to slip continuously and results in overheating and damage to important components (e.g. clutch, polymer housing components.) Such damage could, among other things, cause the cutting attachment to rotate at idle. Mowing heads are to be used only on trimmers equipped with a line-limiting blade in the deflector in order to keep the line at the proper length (see "Main Parts" chapter in your instruction manual.) If the lawn edges are planted with trees or bordered by a fence etc., it is best to use a nylon line head. It achieves a "softer" cut with less risk of damaging tree bark etc. than polymer blades. However, the polymer-bladed STIHL PolyCut produces a better cut if there are no plants along the edge of the lawn. Sharpening is not necessary, and worn polymer blades are easily replaced. 000BA019 KN Warning! To reduce the risk of serious injury, never use wire or metal-reinforced line or other material in place of the nylon cutting lines. Pieces of wire could break off and be thrown at high speed toward the operator or bystanders.
