Mowing Head with Nylon Lines
Nylon line achieves a soft cut for edging 
and trimming around trees, fence posts, 
etc. – less risk of damaging tree bark.
STIHL FixCut
Check the wear limit marks!
N If the raised moldings (1) on the 
base of the attachment are worn as 
shown in the illustration (above 
right), do not continue using the 
mowing head. Install a new one. 
There is otherwise a risk of injury 
from thrown parts of the head.
STIHL Polycut Mowing Head with 
Polymer Blades
For mowing unobstructed edges of 
meadows (without posts, fences, trees 
or similar obstacles).
Check the wear limit marks!
If one of the wear limit marks on the 
PolyCut mowing head is worn through 
(arrow): Do not continue using the 
mowing head. Install a new one. There 
is otherwise a risk of injury from thrown 
parts of the head.
It is important to follow the maintenance 
instructions for the Polycut mowing 
head.
Risk of Kickout (Blade Thrust) with 
Metal Cutting Blades
When using grass cutting blades there is 
a risk of kickout when the rotating blade 
comes into contact with a solid object 
like a tree trunk, branch, tree stump, 
rock or similar. The machine is thrown to 
the right or to the rear – opposite to the 
blade's direction of rotation.
The risk of kickout is greatest when the 
black area of the rotating blade comes 
into contact with a solid object.
To reduce the risk of injury, 
never use steel wire in place of 
the nylon cutting line.
