Sharpening Metal Cutting
Blades
Use a sharpening file (see "Special
N
Accessories") to sharpen dull
cutting attachments. In case of
more serious wear or nicks:
Resharpen with a grinder or have
the work done by a dealer – STIHL
recommends a STIHL servicing
dealer.
Sharpen frequently, take away as
N
little metal as possible – two or three
strokes of the file are usually
enough.

Resharpen the teeth (1) uniformly –
N
do not alter the contour of the parent
blade (2) in any way.
See cutting attachment packaging for
additional sharpening instructions. Keep
the packaging for future reference.
Balancing
After resharpening about 5 times,
N
check the cutting tool for out-of-
balance on a STIHL balancer
(special accessory) or have it
checked by a dealer and re-
balanced as necessary – STIHL
recommends a STIHL servicing
dealer.

Maintaining the Mowing
Head
Placing power tool on the ground
Shut off the engine.
N
Lay your power tool on its back so
N
that the cutting attachment
mounting face is pointing up.
Replacing Nylon Line
2
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
N
head.
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.
Replacing Nylon Line

STIHL PolyCut

Precut lengths of nylon line can be fitted
to the PolyCut in place of the cutting
blades.
