English / USA
The damaged clutch may cause the
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 AutoCut, PolyCut and FixCut
mowing heads produce a clean and tidy
finish.
They may be used only on 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 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
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 AutoCut mowing head
Nylon cutting cord advances auto-
matically 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!
