Stihl FS 500 Instruction Manual page 11

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.
To reduce the risk of injury,
never use steel wire in place of
the nylon cutting line.
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!
FS 500, FS 550
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 Attachments
When using metal cutting attachments
(grass cutting blade, brush knife,
shredder blade, circular saw blade)
there is a risk of kickout when the
rotating blade comes into contact with a
solid object such as a tree trunk, branch,
tree stump, rock or similar. The machine
is thrown to the right or to the rear –
opposite to the attachment's direction of
rotation.
The risk of kickout is greatest when
the black area of the rotating cutting
attachment comes into contact with a
solid object.
Grass Cutting Blade
Use for grass and weeds only – sweep
the brushcutter in an arc like a scythe.
Improper use may damage the
grass cutting blade – risk of
injury from thrown parts.
