Replacing Nylon Line
Always check the mowing head for signs of wear
before replacing the nylon line.
WARNING
If there are signs of serious wear, replace the
complete mowing head.
The nylon mowing line is referred to as "nylon
line" or "line" in the following.
The mowing head is supplied with illustrated
instructions for replacing the nylon line. Keep the
instructions for the mowing head in a safe place.
► If necessary, remove the mowing head.
11.3
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 rotating
mowing head above the grass surface.
► Tap it on the ground once – fresh 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
WARNING
To reduce the risk of injury, always shut off the
engine before adjusting the nylon line by hand.
► Pull the spool up – rotate it about 1/6 turn
counterclockwise until it engages – and allow it
to spring back.
► Pull ends of the lines outward.
Repeat the above procedure as necessary until
both lines reach the limiter blade on the deflec‐
tor.
Rotating the spool from one stop to the next
advances about 4 cm (1 1/2 in) of fresh line.
11.4
Replacing Nylon Line
STIHL PolyCut
Precut lengths of nylon line can be fitted to the
PolyCut in place of the cutting blades.
STIHL DuroCut, STIHL PolyCut
WARNING
To reduce the risk of injury, always shut off the
engine before refilling the mowing head.
► Fit precut lengths of nylon line in the mowing
head as described in the instructions supplied.
