Mowing heads are to be used only on 
trimmer/brushcutters equipped with a 
line-limiting blade in the deflector in 
order to keep the line at the proper 
length (see "Parts and Controls" 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.
!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 (TapAction).
STIHL PolyCut mowing head
Uses either nylon lines or nonrigid, 
pivoting polymer blades.
!Warning!
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.
