Inspection And Maintenance By User - Stihl FS 94 Instruction Manual

Adjusting nylon line
STIHL SuperCut
Fresh line is advanced automatically if
the remaining line is at least 6 cm
(2 1/2 in) long. The blade on the
deflector trims overlong lines to the
correct length.
STIHL AutoCut
With the engine running, hold the
N
rotating mowing head above the
grass surface.
Tap it on the ground once – fresh
N
line is advanced and the blade on
the deflector trims it to the right
length.
Fresh line is advanced every time the
mowing head is tapped on the ground.
For this reason observe the mowing
head's cutting performance during
operation. If the mowing head is tapped
on the ground too often, the line limiter
blade will unnecessarily cut off unused
lengths of nylon line.
Line feed operates only if both lines are
still at least 2.5 cm (1 in) long.
Replacing nylon line
STIHL PolyCut
A length of nylon line can be fitted to the
PolyCut in place of the cutting blades.
