English / USA A damaged clutch may cause a cutting attachment to rotate at idle speed and increase the risk of personal injury from loss of control and from contact with the cutting tool. The STIHL SuperCut, TrimCut, AutoCut and PolyCut mowing heads produce a clean and tidy finish. They are to be used only on brushcutters equipped with a limiter blade in the deflector in order to keep the line at the proper length (see "Parts and Controls" chapter of this 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 with the 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 grass cutting blades are easily replaced. !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. STIHL "SuperCut" mowing head Fresh line is advanced automatically. Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head). STIHL "TrimCut" mowing head Frayed line is replaced by a simple adjustment (see instruction sheet supplied with mowing head). STIHL "AutoCut" mowing head Nylon cutting cord advances automatically when tapped against the ground. STIHL "PolyCut" mowing head Uses either nylon lines or nonrigid plastic blades. Important! Three rectangular wear limit marks are applied to the base (periphery) of the PolyCut. To reduce the risk of serious injury from breakage of the head or blades, the PolyCut must not be used when it has worn as far as one of these marks. It is important to follow the maintenance instructions supplied with the head! 000BA015 KN 002BA177 KN 14 FS 300, FS 350, FS 400, FS 450, FS 480

A damaged clutch may cause a cutting
attachment to rotate at idle speed and
increase the risk of personal injury from
loss of control and from contact with the
cutting tool.
The STIHL SuperCut, TrimCut, AutoCut
and PolyCut mowing heads produce a
clean and tidy finish.
They are to be used only on brush-
cutters equipped with a limiter blade in
the deflector in order to keep the line at
the proper length (see "Parts and
Controls" chapter of this 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 with the 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
grass cutting blades are easily replaced.
