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 limiting
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.

STIHL TrimCut

To reduce the risk of injury, always shut

N

Pull ends of the lines outward.

Repeat the above procedure as
necessary until both lines reach the
limiter blade on the deflector.
Rotating the spool from one stop to the
next advances about 4 cm (1 1/2 in) of
fresh line.
